Answer:
see attached
Step-by-step explanation:
3x(x − 2)(5x + 2)
- (x − 2)(5x + 2) expand
- 5x² - 8x - 4
- 3x ( 5x² - 8x - 4) expand
- 15x³ - 24x² - 12x
Here! :) i hope this helps bunny!
Answer:
20.27
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 
Using the Central Limit Theorem for Means, what is the standard deviation for the sample mean distribution?
This is s when
. So

So the correct answer is:
20.27
Answer:
no solution
Step-by-step explanation:
Given
(6x + 12) - 2(x - 7) = 19 ← distribute parenthesis on left side
2x + 4 - 2x + 14 = 19 , that is
18 = 19 ← not possible
This indicates the equation has no solution
