<u>Answer:</u>
The point-slope equation of the line is
or 
<u>Solution:
</u>
Let us assume that the slope is m and the y intercept of the line is b
Hence,
--------- (i)
y intercept means we need to find the value of y when x is 0
Here the line passes through point (4,-6) and slope m = (-2)
Now putting the point (4,-6) in equation (i) we get,





So, the equation of the line will be will be
or 
Answer:
95%
Step-by-step explanation:
Given that in a large class, students' grade in a test followed the normal distribution.
The normal distribution is symmetric about the mean, bell shaped and having area of more than 99% between 3 std deviations from the mean on either side.
We are to find the percent of grades is between two standeard deviation below the mean and two standar deviation above the mean (that is in between Xbar-2S and Xbar+2S grades)
where x bar is the mean and s = std devition
This is equivalent to 100*Prob that X lies between these two values
As per normal distribution curve 68, 95, 99 rule we get
approximately 95% lie between these two values.
41 is a prime number so the factors are only 1 and 41
