Answer:
1568
Step-by-step explanation:
The computation of the minimum sample size is shown below:
Given that
Error E = 11
The population standard deviation 
=217
Confidence level 1-α = 95%
Now following formula should be used
n > (Zalpha ÷ 2 × sigma ÷ E)^2
As we know that
Zalpha ÷ 2= 1.96
Now the sample size is
n> (1.96 × 202 ÷ 10)^2
= 1568
Answer:
12 = 3 + p
Step-by-step explanation:
She has a total of 12 pencils
3 of them are red
The rest are "p"
p + 3 must equal 12 because she has a total of 12 pencils consisting of 3 red and "p" as the rest
Answer:
1. Calculate the slope from 2 points.
2. Substitute either point into the equation.
3.Solve for b, which is the y-intercept of the line.
4. Substitute b, -1, into the equation from step 2.
Step-by-step explanation:
I gave you one extra than what you expected, if thats ok.
Hope this helps : )
