I think 5.55 will travel in 3.7 seconds
Answer:
Step-by-step explanation:
- The Z-score allows you to decide if your sample is different from the population mean. In order to use z, you must know four things:
- The population mean.
- The population standard deviation.
- The sample mean.
- The sample size.
- Usually in stats, you don’t know anything about a population, so instead of a Z score you use a T-Test with a T Statistic.
- The major difference between using a Z score and a T statistic is that you have to estimate the population standard deviation. The T test is also used if you have a small sample size (less than 30).
Answer:
Step-by-step explanation:
<u>The volume formula:</u>
<u>Given:</u>
- d = 0.75 in ⇒ r = d/2 = 0.75/2 in
- h = 0.04 in
<u>The volume of each penny:</u>
<u>The volume of 100 pennies:</u>
- V = 100*π(0.75/2)²(0.04) = π(0.75/2)²(4)
