The answer b because you act like you’re folding the paper in half over the vertical y axis and the points will be in the same spot
Answer:
The correct option is B.
Step-by-step explanation:
It is given that the correlation coefficient between two variables is -0.95.
Correlation coefficient between two variables is denotes by ρ. The value of ρ is leis between -1 to 1.
If
, then it represent perfect negative correlation.
If
, then it represent perfect positive correlation.
If
, then it represent no relationship between the variables.
Since the -0.95 is near to the value -1, therefore we can say that there is a strong negative association between the variables. Option B is correct.

The answer is:
D. ![m(p)=4p-28](https://tex.z-dn.net/?f=m%28p%29%3D4p-28)

Why?</h2>
Inversing a function consists of switching the function (name) and the variable, so, where we have the variable (m for this case) we should rewrite it as the function (p(m)), and then, isolate the function in order to know the inverse function.
So, we are given the function:
![p(m)=\frac{m}{4}+7](https://tex.z-dn.net/?f=p%28m%29%3D%5Cfrac%7Bm%7D%7B4%7D%2B7)
We know that:
![p(m)^{-1}=m(p)](https://tex.z-dn.net/?f=p%28m%29%5E%7B-1%7D%3Dm%28p%29)
Then, rewriting and calculating, we have:
![p(m)=\frac{m}{4}+7](https://tex.z-dn.net/?f=p%28m%29%3D%5Cfrac%7Bm%7D%7B4%7D%2B7)
![p=\frac{m(p)}{4}+7\\\\p-7=\frac{m(p)}{4}\\\\m(p)=(p-7)*4=4p-28](https://tex.z-dn.net/?f=p%3D%5Cfrac%7Bm%28p%29%7D%7B4%7D%2B7%5C%5C%5C%5Cp-7%3D%5Cfrac%7Bm%28p%29%7D%7B4%7D%5C%5C%5C%5Cm%28p%29%3D%28p-7%29%2A4%3D4p-28)
Hence, we have that the answer is:
D. ![m(p)=4p-28](https://tex.z-dn.net/?f=m%28p%29%3D4p-28)
Have a nice day!
Its is 900 because 120 divided by 8 is 15 and 15 times 60 is 900
I believe you mean volume, not area, since the height is given as well.
If the first cake and the second cake are the same size, they'd have the same area and the same volume.
Ratio between 1st pieces and 2nd pieces:
24:40 = 6:10
= 3:5
So for every 3 pieces from the first cake, you get 5 pieces from the second cake.
Therefore, your volume of each piece of the second cake should be 45 cm^3.
Since the height is given as 3 cm, the area of each piece of the second cake should be 15 cm^2. (45/3 = 15)
Working with whole numbers (i'm assuming), the possible dimensions of the second cake pieces would be: 5 cm x 3 cm x 3 cm (and since 3 and 5 are the only integer factors of 15).
Your answer: width x length = 5 cm x 3 cm (or vice versa)
