So hmm check the picture below

$\bf 4x=\cfrac{(6x-2)+(5x-4)}{2}\implies 8x=6x-2+5x-4
\\\\\\
8x-6x-5x=-2-4\implies -3x=-6\implies x=\cfrac{-6}{-3}\implies \boxed{x=2}$

Simple...

when they ask for the rate of change they ask for slope -->>

Using $\frac{ y_{1} - y_{2} }{ x_{1} - x_{2} }$ to find the rate of change for (-3,0) and (-2,-5)

$\frac{0--5}{-3--2}$

$\frac{0+5}{-3+2}$

$\frac{5}{-1}$

m=-5

Thus, your answer.

M- Determine whether or not the procedure described below results in a binomial distribution. If it is not binomial, identify a

Igoryamba

Answer:

A. Yes, the result is a binomial probability distribution.

Step-by-step explanation:

The experiment above depicts a binomial probability distribution because the 4 required conditions are met :

1.) The distribution is independent as the possible outcome of each trial is the same.

2.) There are two possible categories and the result of each trial is one of two outcomes : Yes or No

3.) The number of observation is fixed at sample size of 5500

4.) The probability of success and failure of each trial is the same for all trials in the sample.

Hence, we can conclude that the experiment depicts a binomial probability distribution.
