Answer: the exact form is 9/2 and the decimal form is 4.5 and the mixed number form is 4 and 1/2
Step-by-step explanation:
Answer:
The distribution of the sampled means becomes normally distributed (bell shaped) as the sample size increases.
Explanation:
According to the Central Limit Theorem, if the mean values for increasing sample sizes are obtained, the distribution of sample means will be normally distributed, even if the individual samples do not have normal distributions.
Typically, sample sizes of 30 or greater are recommended.
Answer:
: Arrow hits the ground after 4 seconds.
Step-by-step explanation:
I assume you are going to ask when the arrow hits the ground, right? If so, follow these steps!

We can factor/distribute to solve this...

If this is true, then that means that...


So the solution would be

In this case, we want to use 4.
Answer:
120870
Step-by-step explanation:
Add 93100+27770
Y=-1/2x +3
(y= slope x + or - the y-intercept
y=m(slope)x+/-b(y-intercept))
