A normal distribution has mean μ and standard deviation σ .An x-value is randomly selected from the distribution. Find P(μ−σ≤x≤μ+ 3σ)
P(μ−σ≤x≤μ+ 3σ)=

Answers

Answer:

The probability that a randomly selected  x-value lies between μ − 2σ and μ is the  shaded area under the normal curve shown.  P(μ − 2σ ≤ x ≤ μ) = 0.135 + 0.34 = 0.475

Step-by-step explanation:

Correct Answer is 0.8385

Empirical Rule:

The Empirical Rule states that 99.7% of data observed following a normal distribution lies within 3 standard deviations of the mean. Under this rule, 68% of the data falls within one standard deviation, 95% within two standard deviations, and 99.7% within three standard deviations from the mean.

Here,

The 68-95-99.7 rule for the normal distribution says:

P(μ - σ ≤ x ≤ μ + σ) = 0.68

P(μ - 2σ ≤ x ≤ μ + 2σ) = 0.95

P(μ - 3σ ≤ x ≤ μ + 3σ) = 0.997

By taking the left half of the first interval and the right half of the last

interval, we have:

P(μ - σ ≤ x ≤ μ + 3σ) = 0.5*P(μ - σ ≤ x ≤ μ + σ) + 0.5*P(μ - 3σ ≤ x ≤ μ + 3σ) =

0.34 + 0.4985 = 0.8385

What is the volume of the following rectangular prism?

Answers

Answer:

529 units squared

Step-by-step explanation:

PLZ HELP meeeeeeeeeeeeeeeeeee

Answers

for the first problem:

the equation is x+40=90 (degrees) because since there is a little square, that means that angle is 90 degrees. Since it has been split we can use algebra to solve it. x=50 degrees. They are complementary angles because the add up to 90 degrees.

second one: x= 180-62 degrees or x+62=180 degrees. Since this one is a straight line and all straight lines equal 180 degrees, we can use the same algebra logic and put in 62 degrees. x=118 degrees, and the angles are supplementary because they add up to 180 degrees.

hope this helped!

Answer:

Question 1: x=50°

Question 2: x=118°

Step-by-step explanation:

A right angle has a total of 90 degrees

a straight line has a total of 180 degrees

Question 1:

The first problem is an example of a complementary angle. To work out the value of x you would need to Minus the angle of 40 from the total of 90, this gives you 50. This is because question 1 is a right angle and so is 90°, also by subtracting the angle form the total of 90 you are isolating the value of x.

1) Minus 40 from 90.

[tex]90-40=50[/tex]°

Question 2:

The second question is an example of a supplementary angle. To work out the value of x in the second question you would minus the angle of  62 from the total of 180, this gives you 118. This is because question 2 is a straight line and so has a total angle of 180°, also by subtracting the angle from the total we are isolating the value of x.

1) Minus 62 from 180.

Probability that Garrick is certified = 25
Probability that Molly has not had an accident = 71.87
Probability that Ryan is both certified and has never had an accident =​

Answers

Answer:

Probability that Ryan is both certified and has never had an accident is undefined

Step-by-step explanation:

Given;

Probability that Garrick is certified = P(G) = {25}

Probability that Molly has not had an accident = P(M) = {71.87}

Probability that Ryan is both certified and has never had an accident = P(R) = {?}

Probability of Ryan being certified was not defined,

Probability that Ryan has not had an accident was not also defined

Therefore, Probability that Ryan is both certified and has never had an accident = P(R) = is undefined, since Ryan is not within the given set.

The slope of a line is -3 and it crosses the y-axis at (0,2) Which is the correct equation of the line in slope-intercept form.

Answers

Answer:

The correct equation is Y= -3 x + 2

Step-by-step explanation:

Slope intercept form is Y= mx + b. First plug the slope in for the variable "M."

The Y-intercept is the point on the graph where the "x" value is zero, so, your Y-intercept is 2. Then, plug that in for your "b" value. Hope this helps! Please mark Brainliest! :)

welp > _

Answers

Answer:

5 packs

Step-by-step explanation:

First, take away the $10 from the $120 he has to spend, therefore he then has $110. Then, divide $110 by $20 and you will get 5.5. He can't get half of a pack so he can only get 5 packs. I hope this helped!

The correct statement that describes the domain of the function is the domain is the set of all real numbers greater than or equal to 0 and less than or equal to 5.

What is a function?

A relation is a function if it has only One y-value for each x-value.

The cost of buying "x" packs of light bulbs is given by the following function:

C(x) = 20x + 10

The function C(x) gives the total cost of buying "x" packs of light bulbs, including the cost of the light bulbs and the shipping cost.

Since Billy can only spend a maximum of $120, we can set up an inequality based on the function C(x):

20x + 10 ≤ 120

20x≤ 110

x ≤ 5.5

This means that Billy can buy at most 5 packs of light bulbs with his budget of $120.

Therefore, the correct statement that describes the domain of the function is the domain is the set of all real numbers greater than or equal to 0 and less than or equal to 5.
