find the area of a square, width times height
then find the area of the triangle, width times height divided by 2
Answer:
Step-by-step explanation:
L= 3W
Perimeter = 2(l+w) = 40
2(3w+w) = 40
2*4w = 40
8w =40
w = 5
l = 3*5 = 15
Answer:
The answer is 0
Step-by-step explanation:
0^2 is just 0x1 so 0+9=9
Here are a ton of correct answers. I got a few questions wrong but they still show the correct answer.
Answer:
The mean for the sample mean distribution is 297 minutes.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean
and standard deviation
, a large sample size can be approximated to a normal distribution with mean
and standard deviation
.
Using the Central Limit Theorem for Means, what is the mean for the sample mean distribution?
The mean is the same as the population mean, that is, 297 minutes.
