Answer:
Step-by-step explanation:
The distributive property is for example 3(2*4) the outside number multiplies everything inside the parenthesis. For the communitive, its like opposites, but they give the same answer, for example 4*5, 5*4. And for associative is like the distributive property, but not at the same time, for example, (a*b)*c = a*(b*c) it has the numbers, but pluged in in another type of way
Hope this helps!

Answer:
g(q) = ![\frac{5q}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B5q%7D%7B8%7D)
Step-by-step explanation:
Given
- 7q + 12r = 3q - 4r
Rearrange making r the subject
Add 7q to both sides
12r = 10q - 4r ( add 4r to both sides )
16r = 10q ( divide both sides by 16 )
r =
=
, thus
g(q) = ![\frac{5q}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B5q%7D%7B8%7D)
Answer:
P(x < 92) is 0.16
Step-by-step explanation:
We are given that the normal distribution has a mean of 98 and a standard deviation of 6.
Mean =![\mu = 98](https://tex.z-dn.net/?f=%5Cmu%20%3D%2098)
Standard deviation = ![\sigma = 6](https://tex.z-dn.net/?f=%5Csigma%20%3D%206)
We are supposed to find P(x < 92)
Formula : ![Z=\frac{x-\mu}{\sigma}](https://tex.z-dn.net/?f=Z%3D%5Cfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D)
![Z=\frac{92-98}{6}](https://tex.z-dn.net/?f=Z%3D%5Cfrac%7B92-98%7D%7B6%7D)
Z=-1
Refer the z table for p value
So,p value = 0.1587
So, P(x < 92) is 0.16
Option A is true
Hence P(x < 92) is 0.16
