Hey!
First, let's write the problem,
Factor out the common term, which is 4,
Then, let's factor this part:
We are going to factor it using the difference of squares rule.
Our final factored answer would be,
Thanks!

<span>Yes, it does in fact prove that. It proves that because O and M are on the outer boundaries and once taken away LM=NO as a matter of fact.</span><span />
Z-score is a statistical tool that is used to estimate the probability of finding a number in a normal distribution of data. A normal distribution is described as a function in which the mean is zero, the standard deviation is 1 and that the area under the curve is equal to 1.
The z-score at 86 is z = (86-80)/6 = 1. the probability to the right is 0.1587.
The z-score at 92 is z = (92-80)/6 = 2. the probability to the left is 0.9772.
The difference in probability is equal to 0.8185. We multiply this to the number of total students to get the answer.
Answer:
See below
Step-by-step explanation:
This is a piece-wise function.
4, -4≤ x ≤ -2
f(x) = 2, -2 ≤ x < 2
-3, 2 ≤ x ≤ 4
