Answer:
A) 34.13%
B) 15.87%
C) 95.44%
D) 97.72%
E) 49.87%
F) 0.13%
Step-by-step explanation:
To find the percent of scores that are between 90 and 100, we need to standardize 90 and 100 using the following equation:
Where m is the mean and s is the standard deviation. Then, 90 and 100 are equal to:
So, the percent of scores that are between 90 and 100 can be calculated using the normal standard table as:
P( 90 < x < 100) = P(-1 < z < 0) = P(z < 0) - P(z < -1)
= 0.5 - 0.1587 = 0.3413
It means that the PERCENT of scores that are between 90 and 100 is 34.13%
At the same way, we can calculated the percentages of B, C, D, E and F as:
B) Over 110
C) Between 80 and 120
D) less than 80
E) Between 70 and 100
F) More than 130
Answer:
50
Step-by-step explanation:
The equation that represent the total cost is in form of equation of a line y = mx+c
m is the gradient of the line
c is the intercept (The point where the line cuts the y - axis
If the equation given y = 150x + 50 is graphed, it will look like a straight line and the y- intercept will represent 50 when compared with the general equation of a line.
Answer:
65 square units
Step-by-step explanation:
The easiest way to calculate the area of the given irregular polygon is to <u>divide</u> the shape into a triangle and a trapezoid (see attached diagram).
<u>Area 1: triangle</u>
<u>Area 2: trapezoid</u>
<u>Area of the polygon</u>
Therefore, the area of the polygon is 65 square units.
