Identify the range of the function shown in the graph.
Answer:
C
Step-by-step explanation:
The range is the set of ALLOWED y-values of the function (graph). Also, the range is the y-values for which the function is defined.
Looking at the graph, we see that the graph is defined between y = 1 and y = 7. So the range is 1 ≤ y ≤ 7

a 34 gram sample of a substance that's used to treat thyroid disorders has a k-value of 0.137. find the substance's half-life, in days. round to the nearest tenths.
Answer:
5.1 days
Step-by-step explanation:
Given in the question,
initial amount of substance = 34 grams
k-value = 0.137
To find the half life of this substance we will use following formula
[tex]N(0)/2 = N(0)e^{-kt}[/tex]
here N(0) is initial amount of substance
t is time in days
Plug values in the formula
[tex]34 /2 = 34e^{-0.137t}[/tex]
1/2 = e^{-0.137t}
Take logarithm on both sides
ln(1/2) = ln( e^{-0.137t})
ln(1/2) = -0.137t
t = ln(1/2) / -0.137
t = 5.059
t ≈ 5.1 days (nearest to tenths)
A survey found that women's heights are normally distributed with mean 63.9 in. and standard deviation 3.6 in. The survey also found that men's heights are normally distributed with mean 69.7 in. and standard deviation 3.6 in. Consider an executive jet that seats six with a doorway height of 55.9 in. Complete parts (a) through (c) below. a. What percentage of adult men can fit through the door without bending? The percentage of men who can fit without bending is 0.02%. (Round to two decimal places as needed.) b. Does the door design with a height of 55.9 in. appear to be adequate? Why didn't the engineers design a larger door?
Using the normal distribution, it is found that:
a) The percentage of men who can fit without bending is 0.02%.
b) A very small percentage of people can fit through the door, thus the dimensions are not adequate. Possible, the engineers did not design a large door because of engineering constraints.
In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.Item a:
Men have mean of 69.7 in, thus [tex]\mu = 69.7[/tex]Standard deviation of 3.6 in, thus [tex]\sigma = 3.6[/tex]The proportion is the p-value of Z when X = 55.9, thus:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{55.9 - 69.7}{3.6}[/tex]
[tex]Z = -3.83[/tex]
[tex]Z = -3.8[/tex] has a p-value of 0.0002.
0.0002 x 100% = 0.02%
The percentage of men who can fit without bending is 0.02%.
Item b:
A very small percentage of people can fit through the door, thus the dimensions are not adequate. Possible, the engineers did not design a large door because of engineering constraints.

A number from 8 to 15 is drawn at random. What is the probability that the number is an even number?
Answer:
The probability that the answer is an even number is 50%.
Step-by-step explanation:
There are 8 terms: 8, 9, 10, 11, 12, 13, 14, 15. Even numbers: 8, 10, 12, 14. So, 4 out of the 8 terms are even, which is equivalent to 50%.
The probability that the number is an even number is 1/2.
What is the probability?The probability is defined as the ratio of number of favourable outcomes and the the total number of possible outcome.
A number from 8 to 15 is drawn at random.
The number between 8 to 15 are 8, 9, 10, 11, 12, 13, 14, 15 = 8
Total even number = 8, 10, 12, 14 = 4
The probability that the number is an even number is;
[tex]\rm Probability =\dfrac{Total \ even \ number}{Total \ number}\\\\Probability =\dfrac{4}{8}\\\\Probability =\dfrac{1}{2}[/tex]
Hence, the probability that the number is an even number is 1/2.

There is a 70% chance that your car will get stuck in the snow during the next big snow fall. Given that you are already stuck in the snow with your car, the chance that you will require a tow truck to pull you out is 90%. What is the chance that you will get stuck in the snow with your car AND require a tow truck to pull you out?
Hint: P(A|B)= P(A∩B) / P(B)
66%
63%
78%
29%
Answer:
63%
Step-by-step explanation:
This is a problem of conditional probability.
The two events that are given are:
Car stuck in the snow - Let it be event S. P(S) = 70% = 0.70Require a tow truck - Let it be event T.We have to find the probability of being stuck in the snow AND requiring a tow truck which can be given as P(S and T)
We are also given the conditional probability, which is P(T | S) = 90% = 0.90
Using the given formula for our case we can modify the formula as:
[tex]P(T|S)=\frac{P(S \cap T)}{P(S)}[/tex]
[tex]0.90=\frac{P(S \cap T)}{0.70}\\\\ P(S \cap T)=0.90 \times 0.70\\\\ P(S \cap T)=0.63[/tex]
Therefore, there is 63% (0.63) chance that you will get stuck in the snow with your car AND require a tow truck to pull you out
The probability of getting stuck in the snow and requiring a tow truck is found by multiplying the individual probabilities, resulting in a 63% chance.
The question asks for the probability that you will get stuck in the snow with your car AND require a tow truck to pull you out. To calculate this combined probability (P(A AND B)), we use the rule of multiplication for dependent events, which states P(A AND B) =[tex]P(B|A) imes P(A).[/tex] Here, P(A) is the probability of getting stuck in the snow, and P(B|A) is the probability of requiring a tow truck given that you are stuck.
In numbers, this becomes P(A AND B) = [tex]0.90 imes 0.70 = 0.63 or 63%[/tex]. Therefore, the chance that you will get stuck in the snow and require a tow truck to pull you out is 63%.
Which polynomial function has a leading coefficient of 1, roots –2 and 7 with multiplicity 1, and root 5 with multiplicity 2?
f(x) = 2(x + 7)(x + 5)(x – 2)
f(x) = 2(x – 7)(x – 5)(x + 2)
f(x) = (x + 7)(x + 5)(x + 5)(x – 2)
f(x) = (x – 7)(x – 5)(x – 5)(x + 2)
ANSWER
[tex]f(x) = (x -7)(x - 5) {(x - 5)}(x + 2)[/tex]
EXPLANATION
If the polynomial has a root -2, with multiplicity 1, then (x+2) is a factor.
If the polynomial has root, 7 with multiplicity 1, then (x-7) is a factor.
If the polynomial has root 5, with multiplicity 2, then (x-5)² is a factor of the polynomial.
The fully factored form of the polynomial is
[tex]f(x) =a (x + 2)(x - 7) {(x - 5)}^{2} [/tex]
It was given that the polynomial has a leading coefficient of 1.
Hence a=1.
This implies that,
[tex]f(x) =(x + 2)(x - 7) {(x - 5)}^{2}[/tex]
Or
[tex]f(x) = (x -7)(x - 5) {(x - 5)}(x + 2)[/tex]

In the figure below, △ABC ~ △PQR. If the Area of △ABC is 40 cm2, what is the area of △PQR? show your work.
Answer:
90 square cm.
Step-by-step explanation:
For similar figures, the length of corresponding sides are proportional.
So we can write 4k = 6 where k is the proportionality constant.
Note: In terms of area, the scale factor would be k^2 and in terms of volume, it would be k^3y
Solving 4k = 6, we see that k = 6/4 or 3/2
We need area, so we multiply area of ABC by k^2 to get area of PQR.
[tex]40(\frac{3}{2})^2\\=40(\frac{9}{4})\\=90[/tex]
Area of PQR = 90 cm^2
Answer:
The area of △PQR is [tex]90\ cm^{2}[/tex]
Step-by-step explanation:
step 1
Find the scale factor
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor
so
Let
z-----> the scale factor
x---> the corresponding side triangle PQR
y---> the corresponding side triangle ABC
[tex]z=\frac{x}{y}[/tex]
substitute the values
[tex]z=\frac{6}{4}=1.5[/tex]
step 2
Find the area of triangle PQR
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
so
Let
z-----> the scale factor
x---> the area of triangle PQR
y---> the area of triangle ABC
[tex]z^{2} =\frac{x}{y}[/tex]
we have
[tex]z=1.5[/tex]
[tex]y=40\ cm^{2}[/tex]
substitute the values
[tex]1.5^{2} =\frac{x}{40}[/tex]
[tex]x=40(1.5^{2})=90\ cm^{2}[/tex]

A researcher records the minutes of activity for an SRS of 6 mildly obese people and an SRS of 6 lean people.Use z-scores rounded to two decimal places to answer the following:What is the probability (Image for It appears that people who are mildly obese are less active than leaner people. One study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 mildly obese people exceeds 420 minutes? What is the probability (Image for It appears that people who are mildly obese are less active than leaner people. One study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 lean people exceeds 420 minutes?
Answer:
0.0322; 0.9929
Step-by-step explanation:
Since the data is normally distributed, we use z scores for these probabilities.
The formula for a z score of a sample mean is
[tex]z=\frac{\bar{X}-\mu}{\sigma \div \sqrt{n}}[/tex]
For the sample of mildly obese people, the mean, μ, is 371; the standard deviation, σ, is 65; and the sample size, n, is 6.
Using 420 for X,
z = (420-371)/(65÷√6) = 49/(65÷2.4495) = 49/26.5360 ≈ 1.85
Using a z table, we see that the area under the curve to the left of this is 0.9678. However, we want the area to the right, so we subtract from 1:
1-0.9678 = 0.0322
For the sample of lean people, the mean, μ, is 528; the standard deviation, σ, is 108; the sample size, n, is 6.
Using 420 for X, we have
z = (420-528)/(108÷√6) = -108/(108÷2.4495) = -108/44.0906 ≈ -2.45
Using a z table, we see that the area under the curve to the left of this is 0.0071. We want the area under the curve to the right, so we subtract from 1:
1-0.0071 = 0.9929
The probability that the mean number of minutes of daily activity of the 6 mildly obese people exceeds 420 minutes is about 3.2%. For the 6 lean people, this probability is approximately 0.7%.
Explanation:For this type of problems, we use the concept of z-scores in statistics. The z-score is a measure of how many standard deviations a data point is from the mean. In this case, we will first calculate the standard error by dividing the standard deviation by the square root of sample size and then find the z-score by dividing the value of interest (420 minutes) minus mean by the standard error.
For mildly obese people, mean = 371 min, standard deviation = 65 min, sample size = 6. So, standard error = 65/sqrt(6) ≈26.51. The z-score for 420 min = (420-371)/ 26.51 ≈1.85. This indicates 420 minutes is 1.85 standard deviations above the mean. The probability that z-score exceeds 1.85 (assuming a one-tailed test since we are looking for the mean to be more than 420 minutes) is 0.032 (approximately). Hence, the probability that the mean number of minutes of daily activity of the 6 mildly obese people exceeds 420 minutes is about 0.032 or 3.2%.
For lean people, mean = 528 min, standard deviation = 108 min, sample size = 6. Using the same approach, standard error = 44.11. The z-score for 420 min = (420-528)/44.11 ≈-2.45. This indicates 420 minutes is 2.45 standard deviations below the mean. The probability that z-score is less than -2.45 (assuming a one-tailed test for under 420 minutes) will be more than 99%. The probability that z-score exceeds -2.45 (420 min or more time) is about 1 - 0.993 = 0.007. Hence, the probability that the mean number of minutes of daily activity of the 6 lean people exceeds 420 minutes is about 0.007 or 0.7%.

If [tex]\mathbf{f(x)\ is\ continuous}[/tex] [a,b] and
[tex]\mathbf{f(x)\ is\ differentiable}[/tex] on (a,b),
Then there is a point c in (a,b), such that: [tex]\mathbf{f'(c) = \frac{f(b) - f(a)}{b - a}}[/tex]
The function is given as:
[tex]\mathbf{f(x) = 3x^2 - 4x + 1}[/tex]
And the interval is: [tex]\mathbf{[0,2]}[/tex]
We have
[tex]\mathbf{f'(c) = \frac{f(b) - f(a)}{b - a}}[/tex]
This becomes
[tex]\mathbf{f'(c) = \frac{f(2) - f(0)}{2 - 0}}[/tex]
[tex]\mathbf{f'(c) = \frac{f(2) - f(0)}{2}}[/tex]
Calculate f(2) and f(0)
[tex]\mathbf{f(2) = 3\times 2^2 - 4\times 2 + 1 = 5}[/tex]
[tex]\mathbf{f(0) = 3\times 0^2 - 4\times 0 + 1 = 1}[/tex]
So, we have:
[tex]\mathbf{f'(c) = \frac{5-1}{2}}[/tex]
[tex]\mathbf{f'(c) = \frac{4}{2}}[/tex]
[tex]\mathbf{f'(c) = 2}[/tex]
Recall that:
[tex]\mathbf{f(x) = 3x^2 - 4x + 1}[/tex]
Differentiate
[tex]\mathbf{f'(x)= 6x - 4}[/tex]
Substitute c for x
[tex]\mathbf{f'(c)= 6c - 4}[/tex]
Substitute 2 for f'(c)
[tex]\mathbf{ 6c - 4 = 2}[/tex]
Collect like terms
[tex]\mathbf{ 6c = 4 + 2}[/tex]
[tex]\mathbf{ 6c = 6}[/tex]
Divide both sides by 6
[tex]\mathbf{c = 1}[/tex]
The interval is given as: [0,2]
The value of c is true for interval (0,2).
Hence, the true statement is:
(b) Yes, f is continuous on [0, 2] and differentiable on (0, 2) since polynomials are continuous and differentiable

A. Federal law regulates a consumer's liability for fraudulent charges.
B. Credit card companies do not penalize consumers in cases of fraud.
C. Credit card companies know when charges are not made by the consumer.
D. Federal law states that credit card companies must collect that amount from consumers.
Answer:
A
Step-by-step explanation:
Federal law regulates a consumer's liability for fraudulent charges. Is what I got.
Answer:
A. Federal law regulates a consumer's liability for fraudulent charges.
Step-by-step explanation:
Under FCBA rules if a client reports about the lost cred card befor eit is used by someone else then the owner of the card is not responsible for any charges. As per the rule Card holders liability for unauthorised use of their credit card ends at $50. FCBA is a federal law that was framed in 1974 and allows us to dispute charges and temporarily withhold payment without affecting credit score. It is because of FCBA that she would not be charges more than fifty dollars.
Evaluate 3^2+(6-2)•4-6/3
Answer:
23
Step-by-step explanation:
3^2+(6-2)•4-6/3
Order of operations:
= 9 + (4)•4 - 6/3
= 9 + 16 - 2
= 25 -2
= 23
32+(6−2)(4)− 6/3
your answer is =23
32+(6−2)(4)− 6/3
=9+(6−2)(4)− 6/3
=9+(4)(4)− 6/3
=9+16− 6/3
=25− 6/3
=25−2
=23
