Answer:
6 samples
Step-by-step explanation:
Given :
Sample size, = n
Standard deviation, = 6000
Margin of Error = 2000
Confidence interval, α = 95%
Zcritical at 95% = 1.96
n = (Zcritical * σ) / margin of error
n = (1.96 * 6000) /2000
n = 11760 / 2000
n = 5.88
n = 6 samples
Answer:
Once you know the sum, you can divide that by 12 to get the measure of each interior angle: 1800°/12 = 150°

The formula is as follows
V = L*W* H
V = 12.1 cm * 5.3 cm * 4.2 cm
V =269.346 cm^3
rounded to the nearest tenth
V = 269.3 cm^3
Choice D
