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:
Step-by-step explanation:
Subtract 5 from each side
Youre left with: 47 (21 + 3x) = 36
Use distributive property.
47 * 21 = 987
3 * 74 = 141x
987 + 141x = 36
- 987 from each side
141x = -951
divide each side by 141
x = -6 35/47
1/2 times 8 equals 4.
You multiply by 8 because the denominator is 8 so you have to have that recipe 8 times to get a whole.
The right answer is Nine.
