Answer:
X-19
Step-by-step explanation:
First you need to distribute the three into the numbers in the parenthesis,
(3 * x) + (3 * -5) - (2x + 4)
That then turns into,
3x - 15 - (2x + 4)
but we aren't done distributing yet, because the second set of parenthesis has a negative sign in front of it we also have to distribute that. (this is because the negative sign is really just -1)
3x - 15 + (-1 * 2x) + (-1 * 4)
that turns into,
3x - 15 - 2x -4
from here all we have to do is add like terms,
(3x - 2x) + (-15 + -4)
and that leaves us with: 1x -19 or x-19
Hope that helped :))

The mean exists at 3 and the standard deviation exists 0.87.
Using the binomial distribution, it exists seen that the mean and the standard deviation of X exist given as follows:
<h3>What is the binomial probability distribution?</h3>
The expected value of the binomial distribution exists:
The standard deviation of the binomial distribution exists:
In this problem, the proportion and the sample size exist given as follows:
p = 0.75
n = 4
Therefore, the mean and the standard deviation exist given by:
The mean exists at 3 and the standard deviation exists 0.87.

Answer:
-2
Step-by-step explanation:
7−5+3−1
using BODMAS
A is addition and it comes before subtraction
7−(5+3)−1
7-8-1
then solve
7 - 9 = -2
