F(2) = -5(2) + 7
f(2) = -10 + 7
f(2) = -3
Answer:
l
Step-by-step explanation:
Given the data temperatures to be;

We would require the following to get the 98% confidence interval of the mean body temperature.
Mean, Standard deviation, sample size, Probability of a confidence interval of 98%.
Using a calculator, we can get the mean to be

The standard deviation would be derived to be;

The sample size can be gotten from the question to be;

The probability value of a 98% confidence interval is given to be 2.33
We can then derive the answer using the formula below;
![\mu\pm z^x(\frac{\sigma}{\sqrt[]{n}})](https://tex.z-dn.net/?f=%5Cmu%5Cpm%20z%5Ex%28%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%5B%5D%7Bn%7D%7D%29)
We would substitute into the formula
![\begin{gathered} \mu\pm z^x(\frac{\sigma}{\sqrt[]{n}}) \\ =98.2285+2.33(\frac{1.2230}{\sqrt[]{7}}) \\ =98.2285\pm1.0770 \\ =(97.152,99.306) \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Cmu%5Cpm%20z%5Ex%28%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%5B%5D%7Bn%7D%7D%29%20%5C%5C%20%3D98.2285%2B2.33%28%5Cfrac%7B1.2230%7D%7B%5Csqrt%5B%5D%7B7%7D%7D%29%20%5C%5C%20%3D98.2285%5Cpm1.0770%20%5C%5C%20%3D%2897.152%2C99.306%29%20%5Cend%7Bgathered%7D)
ANSWER:
Unfortunately there's not much we can say other than

If we knew the numbers that replace a,b,c,d, then we could compute the actual numeric distance.
Answer:
I believe its C- 25%
Step-by-step explanation:
If you count how far it is from 15 to 20 (5) and <u>divide</u> that by 1/20 you should end up with 0.25. Turn that into a <u>percent</u> and you get 25%.
Let me know if Im wrong!
