After plotting the data from the table, with the number of times sick per year as a function of the number of apples eaten per week, I can conclude that there is no definite correlation between the two variables. This is because the data points do not have a good fit with any trend, meaning the R-squared value is low. Thus, the number of apples eaten per week has no significant effect on the number of times the people listed get sick per year.
8 ÷ (2/3)
Divide 2/3 first, because it's in the parenthesis.
Divide 8 by the product of 2/3 = 12.
<span>f(x) = the quantity of x plus 7, divided by 5
![f(x)= \frac{x+7}{5}](https://tex.z-dn.net/?f=f%28x%29%3D%20%5Cfrac%7Bx%2B7%7D%7B5%7D%20)

To get the inverse
of any function f(x) [ just make sure that it passes the horizontal line test]
follow the steps:
- Solve for x, i.e separate x in one side
and the other terms in the other side, included f(x).
- Swap x and f(x).
- The result is the inverse of the original
function ![f^{-1}(x)](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29)
So that:
![5*f(x)=x+7\\~\\~\\5f(x)-7=x\\~\\~\\Swap~now\\~\\~\\f^{-1}(x)=5x-7](https://tex.z-dn.net/?f=5%2Af%28x%29%3Dx%2B7%5C%5C~%5C%5C~%5C%5C5f%28x%29-7%3Dx%5C%5C~%5C%5C~%5C%5CSwap~now%5C%5C~%5C%5C~%5C%5Cf%5E%7B-1%7D%28x%29%3D5x-7)
and for the value of 3:
![f^{-1}(3)=5(3)-7=15-7=8](https://tex.z-dn.net/?f=f%5E%7B-1%7D%283%29%3D5%283%29-7%3D15-7%3D8)
I hope that
helps!
Answer:
230 for Daughter and son each
Step-by-step explanation:
