Answer:
6 is the answer for your box :) Double checked :)
Step-by-step explanation:
25.12 = 1/3(12.56h)
multiply both sides by 3 to get rid of the fraction
75.36 = 12.56h
divide both sides by 12.56
6 = h
h = 6
Answer:
The real answer is:
3x^2 -6x+3x-6
Step-by-step explanation:
Answer:
2A /b = h
Step-by-step explanation:
A = 1/2 bh
Multiply each side by 2
2A = 2*1/2 bh
2A = bh
Divide each side by b
2A/b = bh/b
2A /b = h

Answer:
c) 75, 2
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean 
and standard deviation 
, the sampling distribution of the sample mean, with a large sample size, can be approximated to a normal distribution with mean and standard deviation 
.
In this problem, we have that:
Records show that the weights of boxes that it carries have a mean of 75 lb and a standard deviation of 16 lb. This means that 
.
For sample size of 64, find the mean and standard deviation of x bar
We have that 
.
So the correct answer is:
c) 75, 2
