Sorry I don’t now the answer to this problem
Answer:
2.28%
Step-by-step explanation:
The z score is used to determine how many standard deviations that the raw score is above or below the mean. If the z score is positive then the raw score is above the mean and if it is negative then it is below the mean. It is given by:

Answer:
x= 942.22
Step-by-step explanation:
.9x-18=830
.9x=848
x=942.222222222
which will be x= 942.22
Since we know the slope is 3 we have part of the equation already (y=3x+b). Now we need to find the y-intercept. To do that we plug in the point that was given to us in the question and solve for b.
0=3(-5)+b
0=-15+b
15=b
Now that we have the y intercept we can put the equation together.
Answer: y=3x+15
Hope this helps :)
Here we use the equation

Taking points (0,4), (1,2)
Substituting the point (0,4) , we will get

Substituting (1,2) we will get

So we have

Therefore , required equation is
