Answer:
p = 22
z = 8
Step-by-step explanation:
Average is sum of the terms divided by number of terms.
<u>Question # 1:</u>
Given that:
![\displaystyle \frac{p+10}{2} = 16\\\\Multiply\ both\ sides\ by \ 2]]\\ p+10 = 2 \times 16\\\\p+10 = 32\\\\Subtract \ 10\ to \ both \ sides\\\\p = 32-10\\\\p = 22](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7Bp%2B10%7D%7B2%7D%20%3D%2016%5C%5C%5C%5CMultiply%5C%20both%5C%20sides%5C%20by%20%5C%202%5D%5D%5C%5C%20p%2B10%20%3D%202%20%5Ctimes%2016%5C%5C%5C%5Cp%2B10%20%3D%2032%5C%5C%5C%5CSubtract%20%5C%2010%5C%20to%20%5C%20both%20%5C%20sides%5C%5C%5C%5Cp%20%3D%2032-10%5C%5C%5C%5Cp%20%3D%2022)

Answer:
This question is not clear, you might want to add whole problem.
Step-by-step explanation:
A+ny = n
a = n-ny
a = (1-y)n
a/(1-y) = n
<span>n = a/(1-y)</span>
The experimental probability that the next student Estelle talks to will pick science is 1/2.
What is the experimental probability ?
Experimental probability is based on the result of an experiment that has been carried out multiples times
The experimental probability = number of students who liked science / total number of students surveyed
7/14 = 1/2
