Answer: 31
step by step solution: so the function is b(x)=x+41. they want to know what the function would equal when b(-10). so b(-10) means that you would plug (-10) in for x in the function so the function would now be b(x)=(-10)+41. now all you have to do is simplify the function. b(x)=31. so the function b(-10)=x+41 equals 31. hope this helped!!! have a great day.
Answer:
18.5
Step-by-step explanation:
120.25/6.5
The sample size needs to be 96.
First we find the z-score for this confidence interval:
Convert 95% to a decimal: 95/100 = 0.95
Subtract from 1: 1 - 0.95 = 0.05
Divide by 2: 0.05/2 = 0.025
Subtract from 1: 1 = 0.025 = 0.975
Using a z-table (http://www.z-table.com) we look up this value in the chart; the z-score that goes with this value is 1.96.
Now we use the formula
