Answers
Answer: 100
5
Step-by-step explanation:
a) The mean of a normal distribution is also the median. Half the population will have values above the mean. Half of 200 is 100, so ...
... 100 students will have grades above 70%.
b) 84% is 14% above the mean. Each 7% is 1 standard deviation, so 14% is 2 standard deviations above the mean. The empirical rule tells you 95% of the population is within 2 standard deviations of the mean, so about 5% of students (10 students) got grades higher than 84% or lower than 56%. The normal distribution is symmetrical, so we expect about 5 students in each range.
... about 5 students will have grades above 84%.

the width of a rectangle is 7 cm less than twice its length. its area is 30 square cm. find the dimensions
Answers
Answer:
l = 6 cm
w = 5 cm
Step-by-step explanation:
l(2l - 7) = 30
2l^2 - 7l - 30
(2l + 5)(l - 6)
l = 6
2(6) - 7 = 5
The length of a rectangle is 5 more than the width. The area is 500 square feet. Find the length and width of the rectangle.
Answers
Answer:
length = 25ft, width = 20ft
Step-by-step explanation:
Let x= width, so length = x+5
Area = l x w so A = x(x+5)
Since the area is given as 500 sqft, your equation is x(x+5)=500.
Although the numbers are easy enough to factor in your head, mathematically the equation can be solved as a quadratic, as follows:
x^2 + 5x -500 = 0
Using either factoring or quadratic formula, x = 20 (the other value is negative). Therefore the width is 20ft and the length is 25ft.

Suppose that the middle 68% of speeding ticket fines on a highway fall between 93.18 and 118. Give an approximate estimate of the standard deviation of the speeding ticket fines. Assume the fine amount has a normal distribution
Answers
Answer:
The approximate estimate of the standard deviation of the speeding ticket fines is of 12.41.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
Middle 68% of speeding ticket fines on a highway fall between 93.18 and 118.
This means that 93.18 is one standard deviation below the mean and 118 is one standard deviation above the mean. That is, the difference between 118 and 93.18 is worth two standard deviations. So
[tex]2s = 118 - 93.18[/tex]
[tex]s = \frac{(118 - 93.18)}{2}[/tex]
[tex]s = 12.41[/tex]
The approximate estimate of the standard deviation of the speeding ticket fines is of 12.41.

Write the equation of the lines which have the following parameters. Write the equation in slope intercept form.
1. slope = 3; y-intercept = 5
2. slope = 2/5; y-intercept =-10
3. slope = -3/2; y-intercept = -2
4. slope = 18; y-intercept = 0
5. slope = -3.253; y-intercept =-14.159
6. Challenge problem: x-intercept = -2; y-intercept = 6
Answers
Answer:
Step-by-step explanation:
Slope intercept form is :
y = mx + b
where m is the slope and b is the y-intercept.
So, given slope and y-intercept, all you have to do is plug in slope for m and y-intercept for b.
1.) y = 3x + 5
2.) y = 2/5x - 10
3.) y = -3/2x - 2
4.) y = 18x
5.) y = -3.253x - 14.159
For question 6, you need to calculate the slope given the two points then plug in the slope and y-intercept to get the equation.
So to find slope, you use the equation below:
slope = (y2 - y1) / (x2 - x1) = (6-0) / (0 - -2) = (6) / (2) =3
6.) y = 3x + 6
