he equation for the line of best fit is y = 0.39x + 15.89. Which of the following statements is true for the above graph?

Answers

The given equation is a slope intercept form of a line. In which,

y = mx + b

where: y = y coordinate
x = x coordinate
m = slope
b = y-intercept

In the equation, y = 0.39x + 15.89. The y-intercept is 15.89 or approximately 16. Meaning at x = 0, there's already approximately 16 dogs visiting at the park.

Therefore, the answer is the last statement.

ANSWER: The y-intercept of the line is 15.89, meaning that on the day the dog park opened, there were about 16 dogs visiting the park.

The sum of two numbers is $30$. the difference of twice the larger number and three times the smaller number is $5$. what is the positive difference between the two numbers?

Answers

The positive difference between the two numbers is 8, which is found by setting up a system of linear equations based on the sum of the numbers and the difference of twice the larger number and three times the smaller number.

To solve the system of equations given by the problem, we can set up two equations based on the information provided. Let x be the larger number and y be the smaller number. We are given:

The sum of two numbers is $30: x + y = 30.The difference of twice the larger number and three times the smaller number is $5: 2x - 3y = 5.

Solving this system of equations will allow us to find the values for x and y. From the first equation, we can express y in terms of x as y = 30 - x.

Substituting this into the second equation gives us 2x - 3(30 - x) = 5, which simplifies to 2x - 90 + 3x = 5 and further to 5x = 95.

Dividing both sides by 5, we find x = 19. Now we can determine y by plugging x back into the first equation, resulting in y = 30 - 19, so y = 11.

The positive difference between the larger and smaller number is 19 - 11 = 8.

Which of the following is the inverse of the statement, "If it is an orange, then it is a citrus fruit"? A.If it is a citrus fruit, then it is not an orange. B.If it is a citrus fruit, then it is an orange. C.If it is not an orange, then it is not a citrus fruit. D.If it is not a citrus fruit, then it is not an orange.

Answers

Your answer would be D.If it is not a citrus fruit, then it is not an orange. The reason why is because there are multiple citrus fruit. A does not make sense because they just told you that an orange is a citrus fruit so that statement is invalid. B and C does not make sense because it's not always a true statement because of the multiple citrus fruit situation I explained earlier.

C is the answer i think.

Maximum for p=3x+2y
Answers:
A. (2,1)
B. (6,2)
C. (2,5)
D. (3,5)

Answers

First, we'd need to find the feasible region which is bounded by the constraints 2 ≤ x ≤ 6, 1 ≤ y ≤ 5 and x + y ≤ 8. Let's graph all of them and we'll get the feasible region as unshaded in the attached image. To find the maximum for p = 3x + 2y, we'll plug the coordinates of the vertices in and compare them.
p(6,1) = 3(6) + 2(1) = 20
p(2,1) = 3(2) + 2(1) = 8
p(2,5) = 3(2) + 2(5) = 16
p(3,5) = 3(3) + 2(5) = 19
p(6,2) = 3(6) + 2(2) = 22
So the maximum value of p is 22 as x = 6 and y = 2.

A plane can fly 11 miles per minute. The plane will fly 6 trips, and each trip is 500 miles. How many hours will the plane fly? Show your work to receive full credit. (10 points)

Answers

So, we are given the speed in mi/min. We want to convert this to mi/hr. We can do this through cross multiplication.

(11 miles/1min) * (60min/hr) = 660 mi/hr

Now, we need to find the total distance flown:
TD= 6 trips*(500 miles/1 trip) = 3,000 mi

Lastly, we find total time using our converted speed and total distance.

speed = (total distance (in miles))/(total time (in hours))

660mi/hr= 3000mi / t
660t=3000
t=3000/660
t= 4.54 hrs

Answer: The plane will fly a total of about 4 and a half hours.

the answer is actually in the question, but you have to write it out mathematically.

he needs at least $200 per week:

20t + 7b > 200 (greater than or equal to)

he can work up to 25 hours per week:

t + b < 25

so this is your system of inequalities. hope this helps!

Find the height of the pole if the shadow of a boy 6 ft. tall is 3 ft. and the shadow of the pole is 2 1/3 yards. 1 yards 4 feet 14 feet

Answers

Hi there! To solve this question, we can write and solve a proportion. We put shadow/height = shadow/x. We do this, because we're looking for the height of the pole and we already know the how big the shadow of the pole is. The yards need to be converted to feet. There are 3 feet in one yard and 3 * 7/3 is 21/3 or 7 in simplest form. The pole casts a shadow 7 feet tall. Plug in the numbers like this: 3/6 = 7/x. Cross multiply the values in order to get 3x = 42. now, you divide each side by 3 to isolate the "x". When you, you get x = 14. There. The height of the pole is 14 feet. The answer is C: 14 feet.

Two fair dice are rolled. find the probability of a "double" given that the sum is 11.

Answers

Star with the statement: "Given that the sum is 11"
which may seem a bit odd considering its the last part of the problem

The "given" is important as it sets up the constraints of what we're dealing with. In this case, we know 100% (we can see or someone told us without lying) that the sum is 11. We don't know what the individual values are but we know they add to 11.

What are the ways to add to 11? Well they are...
5+6 = 11
6+5 = 11
so there are 2 ways to do it. As you can see, none of those ways involve a double. A double is where we have two of the same values (eg: snake eyes which is 1 and 1 giving 1+1 = 2 as the sum). It turns out that it's impossible to have doubles add to any odd number.

So if we know the sum is 11, and we're asking "what is the probability of rolling doubles", then the answer is 0.
The 0 indicates "impossible" or "certainty of it never happening".

There are 0 (zero) probability of a "double" given that the sum is 11.

What is mean by Probability?

The term probability refers to the likelihood of an event occurring.

Given that;

Two fair dice are rolled.

And, The probability of a "double" given that the sum is 11.

Now,

Since, The the probability of a "double" means;

''Two fair dice after rolled gives the same numbers.''

Since, The sum of two same number is always gives the even number.

So, We cannot get the sum 11.

Hence, There are 0 (zero) probability of a "double" given that the sum is 11.
