Answer:
26
Step-by-step explanation:
given f(x)=3(2-x)+5 what is the value of f(-5)?
f(x)=3(2-(-5))+5 x minus a negative is a plus 2 - -5 = 2 +5
= 3(7) + 5
= 21 +5
= 26
Answer:histogram 4

Histogram 1 only shows one number for that section so i assume that it should be number 4.
Answer:
The minimum sample size is n = 75 so that the desired margin of error is 5 or less.
Step-by-step explanation:
We are given the following in the question:
Population variance = 484
Standard deviation =
Confidence level = 0.95
Significance level = 0.05
Margin of error = 5
Formula:
Margin of error =
Putting values, we get
Thus, the minimum sample size is n = 75 so that the desired margin of error is 5 or less.
