Answer:
a. 22.5953 b. 3.6
Step-by-step explanation:
A. When a number is in parentheses and directly beside another number it means multiple. so you simply multiply to two together.
B. When a number is in parentheses but has a division sign or forward slash in front of it it is simply keeping the number separate as not to create confusion so just divide them.
ps. when you teacher says shoe work he/she means dint just write an answer. They mean write out beside your answer "2.43 x 9.71 = 22.5953" & "4.68 ÷ 1.3 = 3.6"
Answer:
Mean 24, standard error 0.8
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean
and standard deviation
, the sample means with size n of at least 30 can be approximated to a normal distribution with mean
and standard deviation, also called standard error ![s = \frac{\sigma}{\sqrt{n}}](https://tex.z-dn.net/?f=s%20%3D%20%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D)
In this problem, we have that:
![\mu = 24, \sigma = 6.4, n = 64](https://tex.z-dn.net/?f=%5Cmu%20%3D%2024%2C%20%5Csigma%20%3D%206.4%2C%20n%20%3D%2064)
What are the mean and the standard error of the sample mean?
By the Central Limit Theorem, mean 24 and standard error ![s = \frac{6.4}{\sqrt{64}} = 0.8](https://tex.z-dn.net/?f=s%20%3D%20%5Cfrac%7B6.4%7D%7B%5Csqrt%7B64%7D%7D%20%3D%200.8)
Answer:
I believe it is A on number one
Step-by-step explanation:
If you turn them into decimals and Monday would be 0.5 Tuesday would be 0.6 and Wednesday would be 0.5 and Thursday would be 0.625 and Friday would be 0.7 so she ran the farthest.
