The random variable X has a uniform distribution with values between 16 and 24. What is the mean and standard deviation of X
Answer:
[tex]Mean = 20[/tex]
[tex]SD = 2.31[/tex]
Step-by-step explanation:
Given
[tex]a = 16[/tex]
[tex]b = 24[/tex]
Solving (a): The mean
The mean of a uniform distribution is:
[tex]Mean = \frac{1}{2}(a + b)[/tex]
This gives:
[tex]Mean = \frac{1}{2}(16 + 24)[/tex]
[tex]Mean = \frac{1}{2}(40)[/tex]
[tex]Mean = 20[/tex]
Solving (b): The standard deviation
The standard deviation is:
[tex]SD = \sqrt{\frac{(b - a)^2}{12}}[/tex]
This gives:
[tex]SD = \sqrt{\frac{(24 - 16)^2}{12}}[/tex]
[tex]SD = \sqrt{\frac{(8)^2}{12}}[/tex]
[tex]SD = \sqrt{\frac{64}{12}}[/tex]
[tex]SD = \sqrt{5.333}[/tex]
[tex]SD = 2.31[/tex]
Alfonso has 435 stamps in his collection. He wants to collect at least
815 stamps. Write and solve an inequality to determine how many
more stamps Alfonso must collect to reach his goal. Let d represent the
number of stamps Alfonso must collect to reach his goal.
435 + d-815; d-380
435 + > 815;d > 380
435 + d 2815;d > 815
435 +0 2 815; d 2380
Answer:
Inequality: [tex]435 + d \geq 815[/tex]
Solution: [tex]d \geq 380[/tex]
Step-by-step explanation:
He has 435 stamps in his collections.
He will collect d stamps, and he wants to collect at least 815 stamps, that is, the sum of 435 and d has to be at least 815.
So the inequality is given by:
[tex]435 + d \geq 815[/tex]
And the answer is given by:
[tex]d \geq 815 - 435[/tex]
[tex]d \geq 380[/tex]
What is the slope of a line that is perpendicular to the line y = 8x + 5?
Answer . m= -1/8
Step-by-step explanation:
The perpendicular slope is the negative reciprocal. Meaning that the numerator and denominator are switched and the sign of the slope becomes the opposite. (if the slope was -8, then the perpendicular slope would be 1/8)

the length of x is option H. x=16
PLEASE HELP WILL MARK BRAINLIEST!!!!!
The numbers inside the parenthesis is the value of x, uses the equation associated with the value of x and solve.
H(1) Since 1 fits 1≤x≤3 use x^3
x^3 1^3 = 1
h(1) = 1
h(4) 4 fits x >3, so use 5
h(4) = 5

Johann takes a random sample of 101010 of his coworkers and asks them each how many hours they worked in the past week. Assume that their hours worked are independent, and let HHH represent the average number of hours worked. Is HHH a binomial variable
Answer:
there is no success or failure in the scenario
Step-by-step explanation:
khan academy
The average number of hours worked. Is not a binomial variable.
Binomial variable.
A binomial variable is a variable that can take either of two forms. It could either be heads or tail, yes or no and success or failure. For example, if a coin is tossed, it can either be heads or tail. Thus, it is a binomial variable.
The average hours worked can have more than two values. Thus it is not a binomial variable.

Find the zeros of the function.
Enter the solutions from least to greatest.
f(x) = 5x^2 - 20
lesser x =
greater x =
Answer:
lesser x = -2
greater x = 2
Step-by-step explanation:
The values of a function f(x) are the values of x for which f(x) = 0.
In this question:
[tex]f(x) = 5x^2 - 20[/tex]
So, finding the zeros:
[tex]5x^2 - 20 = 0[/tex]
[tex]5x^2 = 20[/tex]
[tex]x^2 = \frac{20}{5}[/tex]
[tex]x^2 = 4[/tex]
[tex]x = \pm \sqrt{4}[/tex]
[tex]x = \pm 2[/tex]
So
lesser x = -2
greater x = 2
