Answer:
The required equation of the line is:
Step-by-step explanation:
Given the equation
comparing the equation with the slope-intercept form
Here,
so the slope of the line is -4.
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so
The slope of the perpendicular line will be: 1/4
Therefore, the point-slope form of the equation of the perpendicular line that also intersects the point (8, 1) is:
add 1 to both sides
Answer:
The probability that the average score of a group of n = 4 people is between 70 and 75=0.13591
Step-by-step explanation:
We are given that
n=4
We have to find the probability that the average score of a group of n = 4 people is between 70 and 75.
Hence, the probability that the average score of a group of n = 4 people is between 70 and 75=0.13591
D=20 because if you divide 70 by 3.5 you get d. hope this helps!
