Answer:
Option D is correct.
Rejecting the null hypothesis means that;
There is sufficient evidence to support the claim that the mean is greater than 32 miles per gallon.
Step-by-step explanation:
For hypothesis testing, the first thing to define is the null and alternative hypothesis.
In hypothesis testing, especially one comparing two sets of data, the null hypothesis plays the devil's advocate and usually takes the form of the opposite of the theory to be tested. It usually contains the signs =, ≤ and ≥ depending on the directions of the test. It usually maintains that, with random chance responsible for the outcome or results of any experimental study/hypothesis testing, its statement is true.
The alternative hypothesis usually confirms the theory being tested by the experimental setup. It usually contains the signs ≠, < and > depending on the directions of the test. It usually maintains that significant factors other than random chance, affect the outcome or results of the experimental study/hypothesis testing and result in its own statement.
For this question, Carter Motor Company claims that its new sedan, the Libra, will average better than 32 miles per gallon in the city. And since this is talking distance covered per gallon of fuel, better means that the new sedan will average more than 32 miles per gallon.
So, the null hypothesis negating this claim would be that there isn't significant evidence to conclude that the average of the new sedan will be better or greater than 32 miles per gallon.
That is, the new average will be less than or equal to 32 miles per hour.
And the alternative hypothesis will confirm the claim that there is significant evidence to conclude that the average of the new sedan will be better or greater than 32 miles per gallon.
Mathematically,
The null hypothesis is represented as
H₀: μ ≤ 32 miles per gallon
The alternative hypothesis is given as
Hₐ: μ > 32 miles per gallon
So, after the hypothesis test has been conducted, rejecting the null hypothesis means accepting the alternative hypothesis and its statement that there is significant evidence to conclude that the average of the new sedan will be better or greater than 32 miles per gallon.
Hence, option D is correct.
Hope this Helps!!!
The conclusion of the hypothesis test indicates that there is sufficient evidence to support the claim that the mean fuel efficiency of the new Libra sedan is greater than 32 miles per gallon.
Explanation:From the noun hypothesis testing conducted, the conclusion drawn is to reject the null hypothesis. In non-technical terms, rejecting the null hypothesis means that based on the data collected and analyzed, there is sufficient statistical evidence to support the claim that contrary to the null hypothesis, the average (or 'mean') miles per gallon of the new Libra sedan is indeed greater than 32 miles per gallon. These results should confirm Carter Motor Company's assertions about their vehicle's fuel efficiency.

I want to know if mammal usually have more teeth than reptiles
Final answer:
While the number of teeth varies among species, mammals usually have more complex dentition than reptiles due to their heterodont (four different types) teeth, compared to reptiles' homodont teeth. Most mammals are diphyodonts with two sets of teeth over their lifetime, unlike many reptiles that replace their teeth continuously.
Explanation:
Mammals generally have a more complex dental structure than reptiles due to their heterodont dentition. Mammals have four different types of teeth: incisors, canines, premolars, and molars, each specialized for different dietary functions such as cutting, tearing, and grinding. In contrast, most other vertebrates, including reptiles, possess homodont teeth, meaning their teeth are all the same type and shape, which often don't vary much in structure compared to mammals.
This difference in dentition is related to the various diets that mammals adapt to, allowing them to process different kinds of foods more efficiently. Furthermore, most mammals are diphyodonts, meaning they have two sets of teeth in their lifetime—deciduous ("baby") teeth and permanent teeth—compared to many reptiles that replace their teeth throughout their lives.
In terms of the absolute number of teeth, it varies widely among species in both groups. Some reptiles indeed have a high number of teeth; for instance, a crocodile has many sharp, conical teeth. However, it's not accurate to say that all reptiles have more teeth than all mammals because there is a great deal of variation within each group, with some mammals having more teeth than certain reptiles, and vice versa.
The Scholastic Aptitude Test (SAT) is a standardized test for college admissions in the U.S. Scores on the SAT can range from 600 to 2400. Suppose that PrepIt! is a company that offers classes to help students prepare for the SAT exam. In their ad, PrepIt! claims to produce "statistically significant" increases in SAT scores. This claim comes from a study in which 427 PrepIt! students took the SAT before and after PrepIt! classes. These students are compared to 2,733 students who took the SAT twice, without any type of formal preparation between tries. We conduct a hypothesis test and find that PrepIt! students significantly improve their SAT scores (p-value < 0.0001). Now we want to determine how much improvement we can expect in SAT scores for students who take the PrepIt! class. Which of the following is the best approach to answering this question? Group of answer choices Use the sample mean 29 to calculate a confidence interval for a population mean. Use the difference in sample means (500 − 529) in a hypothesis test for a difference in two population means (or treatment effect). Use the difference in sample means (500 − 529) to calculate a confidence interval for a difference in two population means (or treatment effect). Use the difference in sample means (29 and 21) in a hypothesis test for a difference in two population means (or treatment effect).
The best approach to determine the average improvement in SAT scores for PrepIt! students is to calculate a confidence interval for the difference in two population means using the sample mean differences, option A.
To determine the average improvement in SAT scores for students who take the PrepIt! class, the best approach is to use the difference in sample means to calculate a confidence interval for a difference in two population means (or treatment effect), option A.
This involves taking the mean SAT score before the PrepIt! class and the mean SAT score after the class and computing the confidence interval for this difference. Doing this calculation will provide an interval estimate that shows the range of values within which the true mean difference in SAT scores, due to the PrepIt! class, is likely to fall. For instance, if the mean SAT score improvement is 29 points, we would use this value and the appropriate standard error and confidence level to calculate the confidence interval.

the sum of two numbers is 9 and their difference is 5.
What are the two numbers?
To solve this problem, we can set up a system of equations using the information given and solve it using the substitution method.
Explanation:To solve this problem, we can set up a system of equations using the information given. Let's call the two numbers x and y.
From the given information, we can write:
x + y = 9 (equation 1)
x - y = 5 (equation 2)
To solve this system, we can use the method of substitution or elimination. Let's solve it using the substitution method:
From equation 2, we can isolate x by adding y to both sides:
x = y + 5
Now substitute this expression for x in equation 1:
(y + 5) + y = 9
Combine like terms:
2y + 5 = 9
Subtract 5 from both sides:
2y = 4
Divide both sides by 2:
y = 2
Now substitute this value for y in equation 1:
x + 2 = 9
Subtract 2 from both sides:
x = 7
So, the two numbers are 7 and 2.
In 2009, a survey of 23 people who had home access to the Internet asked them how much they paid per month for that access, rounded to the nearest dollar. The following data show each person's response, from smallest monthly bill to largest. $14, $18, $18, $18, $19, $19, $23, $23, $23, $25, $25, $25, $25, $25, $26, $26, $26, $27, $33, $37, $42, $58 Make a histogram of the data on the cost of Internet access using the intervals 0-4, 5-9, 10-14, and so on. Describe the distribution of values in words.
Answer:
See attachment for histogram
Step-by-step explanation:
The histogram shows that the majority of customers have monthly bills between 25 to 29. There is a break between $45-$54 monthly bill as there is no customer with this amount of monthly bill. Then there is one customer between $55-$59 monthly bill.
Final answer:
The histogram of Internet costs shows a concentration between $19-28, with the majority of prices ranging from $23 to $27. It is unimodal and right-skewed with costs spread from $14 to $58, indicating that a smaller number of individuals pay much higher prices for internet access.
Explanation:
To create a histogram of the data on the cost of Internet access using intervals of $5, we will first determine the range of values within each interval:
14-18: $1419-23: $18, $18, $18, $19, $19, $23, $23, $2324-28: $25, $25, $25, $25, $25, $26, $26, $26, $2729-33: $3334-38: $3739-43: $4244-48: None49-53: None54-58: $58From the histogram, we can see that the majority of responses fall within the $19-28 range, specifically between $23 and $27. This signifies that most people in the survey pay a moderate price for Internet access. The distribution is unimodal, skewing right, and has a spread from $14 to $58, with a slight concentration of high costs on the right indicating few individuals pay significantly more for internet access.
Which function describes the graph below? On a coordinate plane, a curve crosses the y-axis at (0, 7), decreases to negative 1, and then increases again to 7. y = 8 cosine (x) + 3 y = 4 cosine (x) + 3 y = 4 sine (x) + 3 y = 8 sine (x) + 3
Answer:
y = 4 cosine (x) + 3
Step-by-step explanation:
A curve crosses the y-axis at (0, 7)
This means that when x = 0, y = 7
We have that:
sin(0) = 0, cos(0) = 1.
Let's see which of the functions respect this condition:
y = 8 cosine (x) + 3
y(0) = 8cos(0) + 3 = 8 + 3 = 11. Incorrect.
y = 4 cosine (x) + 3
y(0) = 4cos(0) + 3 = 4 + 3 = 7. Correct.
y = 4 sine (x) + 3
y(0) = 4sin(0) + 3 = 0 + 3 = 3. Incorrect.
y = 8 sine (x) + 3
y(0) = 8sin(0) + 3 = 0 + 3 = 3. Incorrect.
Decreases to negative 1, and then increases again to 7.
This means that the amplitude is 7-(-1) = 8, which means that the term which multiplies the function is 8/2 = 4. From above, we have already seen that the answer is y = 4 cosine (x) + 3.
Answer:
Pretty sure its' b (y=4Cos(x)+3)
Step-by-step explanation:
Take the max minus the min, equals 8 then times 1/2 equals 4.
Since it starts at the max, that is a characteristic of cosine NOT sine.

a dog is tied to a wooden stake in the backyard. his chain is 18.6 feet long and he runs around in circles pulling the leash as far as it can go. if he runs around the circle 10 times, how far has he run
Answer:
The dog ran 1,168.1 feet, approximately.Step-by-step explanation:
Givens
The chain is 18.6 feet long.Notice that the chain represents the radius of the circle trajectory, because the dog is running pulling the leash as far as it can go.
So, the radius of the circle is 18.6 feet long.
Now, the length of the circumference is
[tex]L=2 \pi r[/tex]
Replacing the radius, we have
[tex]L=2(3.14)(18.6)\\L=116.81 ft[/tex]
So, one lap is equal to 116.81 feet. But the dog ran 10 times, which means it ran a total distance of
[tex]d=10(116.81ft)=1168.1 \ ft[/tex]
Therefore, the dog ran 1,168.1 feet, approximately.

Explanation:The subject of the question is related to statistics and business with a focus on quality control in a grocery chain. The quality control department at Food Town Inc. conducts a check comparing scanned prices to posted prices. In essence, management is interested in understanding any possible relationship between error rates for regularly priced and specially priced items. A simple way to understand this is through the concept of a correlation.
Correlation is a term in statistics used to indicate the degree to which two or more attributes or measurements on the same group of elements show a tendency to vary together. By looking at the data, especially the error rates (overcharge and undercharge) on regular and special priced items, one could check if there's a negative or positive correlation between these variables.
It seems at first glance that regularly priced items incur fewer errors overall than specially priced items, especially in overcharging. A statistical correlation test, such as the Pearson correlation, can further confirm or refute this observation.

Given: mKP=2mIP, mIVK =120°
Find: m∠KJL.
Answer:
The measure of angle KJL is 40°.Step-by-step explanation:
Givens
[tex]m(KP)=2m(IP)[/tex]
[tex]m(IVK)=120\°[/tex]
Notice that
[tex]m(KP)+m(IP)+m(IVK)=360\°[/tex], by definition sum of arcs.
Replacing given values, we have
[tex]2m(IP)+m(IP)+120\°=360\°\\3m(IP)=360\° - 120\°\\m(IP)=\frac{240\°}{3}\\ m(IP)=80\°[/tex]
Which means [tex]m(KP)=2(80\°)=160\°[/tex]
Notice that arc KP is the subtended arc by angle KJL.
We know that the angle formed by a tangen and a secant is equal to one-half of the difference of the intercepted arcs.
[tex]m\angle KJL = \frac{1}{2} (m(KP)-m(IP))\\m \angle KJL = \frac{1}{2}(160\° - 80\° )=\frac{1}{2}(80\°)=40\°[/tex]
Therefore, the measure of angle KJL is 40°.
The archway to the entrance of an art gallery can be
modeled by y = -}(x - 5)(x + 5), where x and y
are measured in feet. The x-axis represents the floor.
Find the width of the arch at floor level.
The width of the arch at floor level is 5 feet.
Explanation:The equation given to model the archway to the entrance of an art gallery is y = -}(x - 5)(x + 5). To find the width of the arch at floor level, we need to find the x-values that correspond to y = 0. Setting y = 0 and solving for x, we get:
0 = -}(x - 5)(x + 5)
0 = (x - 5)(x + 5)
Using the zero product property, we can separate the equation into two parts:
x - 5 = 0 and x + 5 = 0
Solving each equation separately, we get:
x = 5 and x = -5

The width of the arch at floor level is the distance between these points, which is 10 feet (5 - (-5) = 10).
The archway to the entrance of an art gallery is modeled by the equation y = -1(x - 5)(x + 5). To find the width of the arch at floor level (y = 0), we need to determine the x-intercepts of the equation.
1. Set y = 0 in the equation: 0 = -1(x - 5)(x + 5).
2. This simplifies to (x - 5)(x + 5) = 0.
3. Setting each factor to zero, we get x - 5 = 0 or x + 5 = 0.
4. Solve these equations for x: x = 5 or x = -5.
The x-intercepts are -5 and 5.
Therefore, the width of the arch at floor level is the distance between these points, which is 10 feet (5 - (-5) = 10).
Captain Ishaan has a ship, the H.M.S Crimson Lynx. The ship is four furlongs from the dread pirate Michael and his merciless band of thieves.
If his ship hasn't already been hit, Captain Ishaan has a probability 5/2 If his ship has been hit, Captain Ishaan will always miss.
If his ship hasn't already been hit, dread pirate Michael has a probability 8/3 of hitting the Captain's ship. If his ship has been hit, dread pirate Michael will always miss.
If the Captain and the pirate each shoot once, and the Captain shoots first, what is the probability that both the Captain and the pirate hit each other's ships?
Answer: 0
Step-by-step explanation:
The probability of event A happening, then event B, is the probability of event A happening times the probability of event B happening given that event A already happened.
In this case, event A is the Captain hitting the pirate ship and event B is the pirate hitting the Captain's ship.
The Captain fires first, so his ship can't be sunk before he fires his cannons.
So, the probability of the Captain hitting the pirate ship is 2/5
If the Captain hit the pirate ship, the pirate has no chance of firing back.
So, the probability of the pirate hitting the Captain's ship given the Captain hitting the pirate ship is 0.
A marine surveyor uses a rangefinder and a compass to locate a ship and an island in the vicinity of the coast on which she stands. The rangefinder indicates that the island is 353 ft from her position and the ship is 474 ft from her position. Using the compass, she finds that the ship's azimuth (the direction measured as an angle from north) is 320 degrees and that of the island is 58 degrees. What is the distance between the ship and the island?
Answer:
distance between the ship and the island is 465.72 ft
Step-by-step explanation:
given data
island = 353 ft
ship = 474 ft
ship's azimuth = 320 degrees
island = 58 degrees
to find out
distance between the ship and the island
solution
as per given figure we can see that
AC = 353
AB = 474
we get here angle ABC that is = 360 - 320 = 40 degree
and angle BAC is = 180 - 58 = 122
and now we apply here law sign
so
[tex]\frac{BC}{sinA} = \frac{AC}{sinB}[/tex] ...........1
put here value and we get
[tex]\frac{BC}{sin122} = \frac{353}{sin40}[/tex]
BC = 465.72 ft
so distance between the ship and the island is 465.72 ft

Answer:
0
Step-by-step explanation:
Using Descartes' rule of signs, we observe that the signs of the coefficients, + - +, have two changes. Thus there will be 0 or 2 positive real roots, hence 0 or 2 complex roots.
We can do further work to determine if it is 0 or 2. A graphing calculator provides an easy answer.
This function of x has no complex zeros. They are all real.
_____
For a cubic, it isn't always easy to find the zeros. The rational root theorem tells you any rational zeros will be factors of 30. Possibilities are ...
±1, ±2, ±3, ±5, ±6 . . . . . we're pretty sure no roots have magnitude > 6
For x=0, y = 30 . . . . the constant
For x=1, y = 12 . . . . . a smaller value, so we're going in the right direction
For x=2, y = 0 . . . . . one of the real roots
Dividing out this factor*, we get ...
y = (x -2)(x^2 +2x -15)
Factoring the quadratic gives ...

Answer:3/4
Step-by-step explanation:
Here are my reason why 1/2 is greater than 2/6 or 1/6. And it won’t be 2/4 because then it would be 1/2 + 0 or 2/4 + 0.
So 1/4 + 1/2
= 1/4 + 2/4
= 3/4

We have been given that the legs on a right triangle are 15.25 inches and 14.1 inches. We are asked to find the hypotenuse of the right triangle.
We will use Pythagoras theorem to solve our given problem.
[tex]\text{Hypotenuse}^2=\text{Leg}^2+\text{Leg}^2[/tex]
[tex]\text{Hypotenuse}^2=15.25^2+14.1^2[/tex]
[tex]\text{Hypotenuse}^2=232.5625+198.81[/tex]
[tex]\text{Hypotenuse}^2=431.3725[/tex]
Now we will take positive square root on both sides.
[tex]\sqrt{\text{Hypotenuse}^2}=\sqrt{431.3725}[/tex]
[tex]\text{Hypotenuse}=20.7695089012715946[/tex]
Upon rounding to nearest hundredth, we will get:
[tex]\text{Hypotenuse}\approx 20.77[/tex]
Therefore, the length of the hypotenuse is approximately 20.77 inches.
