Answer:
5.3%
Step-by-step explanation:
The first step is to find the z score corresponding to $200.
The next step is to find the area under the standard normal curve to the right of z = 1.62. Some graphing calculators can do this, and there are tables that will help, although many of those show areas to the left of a particular z-score.
Calculator (TI-83/84)
See the attached image.
The command uses 1 x 10^99 as "positive infinity" and calculates the area under the normal curve from 1.62 all the way to the right.
Table
See attached table. This table shows areas to the <u>left</u> of a certain z-score.
Find the entry for 1.62 (it's on page 2 highlighted with a red box). The table says the area to the left of 1.62 is 0.9474.
But the area under the entire curve is 1!
This important fact means that the area to the right of z = 1.62 is 1 - 0.9474 = 0.0536, about 5.3%
(To get the area to the right of z, subtract the area to the left of z from 1.)
Your answer would be D. 16/24 8x3=24 2x8=16 and 5x3=15 8x3=24
First find the slope of the line segment joining the points.
Slope = ((-5)-7)/(1-(-3)) = -3
The slope of any perpendicular to the line is 1/3
Find the midpoint of the line segment by taking the average of the coordinates.
x-coord of midpoint = (-3+1)/2 = -1
y-coord of midpoint = (7-5)/2 = 1
Midpoint : (-1,1)
Point-slope equation for line of slope 1/3 that passes through (-1,1):
y-1 = (1/3)(x+1)
