IQ scores are normally distributed with a mean of 100 and a standard deviation of 15. Using the empirical rule, what percentage of people have an IQ score between 70 and 130?​

Answers

70 = 100 - 2•15 is 2 s.d.'s below the mean.

130 = 100 + 2•15 is 2 s.d.'s above the mean.

By the empirical rule,

Pr [70 ≤ X ≤ 130] = Pr [-2 ≤ Z ≤ 2] ≈ 95%

(where Z is normally distributed with mean 0 and s.d. 1)

Constant terms are terms with no variables attached to them, and will not change under any circumstances. A variable is typically denoted by a Latin Alphabet.

4. 4

The coefficient is the whole number found in front of the variable, typically being multiplied to it. In this case, you are solving for the coefficient that is found in front of g², which is 4.

5. -3c

The coefficient -3 is found at the 3rd term of the expression.

6. -12x & -17x ; 15y & 16y

Like terms are terms with the same variable as well as the same amount of variables. For example x² is not a like term of x, though both variables have x to signify them.

7. 3c

Unlike terms are terms that do not share at least one partner of the same amount of variables. c is a variable by itself with no other terms containing it, and so is your answer.

Write a system of equations and then solve by the method of your choice. Reserved seat tickets for the football game cost $4.00 each and general admission tickets cost $3.00 each. After the game is over, the turnstile count shows 1787 people attended the game. The total receipts were $5792. Find the number of each general admission tickets sold.

Answers

Given :

Reserved seat tickets for the football game cost $4.00 each and general admission tickets cost $3.00 each.

After the game is over, the turnstile count shows 1787 people attended the game. The total receipts were $5792.

To Find :

The number of each general admission tickets sold.

Solution :

Let, general admission are x.

So, Reserved seat tickets will be 1787 - x.

Now, total amount T = 3x + 4( 1787 - x )

T = $5792

3x + 4( 1787 - x ) = $5792

-x + 7148 = 5792

x = 1356

Therefore, the number of each general admission tickets sold are 1356.

Hence, this is the required solution.

The diameter of a cylinder is 5 yd. The height is 4 yd. What is the volume of the cylinder

Answers

Answer:

25 pi square yd OR rounded pi to 3.14: 78.5 square yd

Step-by-step explanation:

Use the formula volume of cylinder = base area × h to determine the value of the base area.

Diameter: 5 yd

Height: 4 yd

(5/2)^2 Pi x 4 = 25 pi square yd.

Answer:

78.5 yd

Step-by-step explanation:

= [tex]\pi[/tex]r²h

= (3.14)(2.5)²(4)

= (3.14)(6.25)(4)

= 19.625 x 4

Write the equation of the line that passes through the points (4,-1) and (4,8). Put
your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.

Answers

Answer:

x = 4

Step-by-step explanation:

Given the points (4, - 1) and (4, 8)

Note the x- coordinates are 4 in both cases.

This indicates the line passing through the points is vertical with equation

x = c

where c is the value of the x- coordinates the line passes through. In this case 4, thus

x = 4 ← equation of vertical line

Let P(t) represent the amount of a certain drug, in milligrams, that is in the bloodstream at time t hours. The rate at which the drug leaves the bloodstream is proportional to the amount of the drug in the bloodstream. The amount of the drug in the bloodstream can be modeled by dP/dt = kP, where k is a constant and t is time, in hours. At time t = 0,500 milligrams of the drug was administered. At the moment when the amount of the drug in the bloodstream is 50 milligrams, the amount is decreasing at a rate of 11.5 milligrams per hour. Which of the following is an expression for P (t)?
A. P(t) = 500 – 0.23t.
B. P(t) = 500 – 0,23 42.
C. P(t) = 500e -0.231.
D. P(t) = e-0.23+ + 499.

Answers

I think its B, I hope this helped!:)

As proportional relationship, the amount decreasing at a rate milligrams per hour can be written in expression P(t) = 500 + e⁻⁰²ˣ

What is Proportional relationship?

In math, the relationships between two variables where their ratios are equivalent is known as proportional relationship.

Given that P(t) represent the amount of a certain drug, in milligrams, that is in the bloodstream at time t hours.

Here we have the rate at which the drug leaves the bloodstream proportional to the amount of the drug bloodstream.

The amount of the drug in the bloodstream can be modeled by dP/dt = kP, where k is a constant and t is time, in hours.

Here we need to find the expression.

Bloodstream = 500 milligrams

So, the expression for this proportional relationship is written as;

P(t) = 500 + e⁻⁰²ˣ

A, B & C form the vertices of a triangle.
∠ CAB = 90°,
∠ ABC = 51° and AB = 8.6.
Calculate the length of BC rounded to 3 SF.

Answers

Answer:

BC ≈ 13.7

Step-by-step explanation:

using the cosine ratio in the right triangle

cos51° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{8.6}{BC}[/tex] ( multiply both sides by BC )

BC × cos51° = 8.6 ( divide both sides by cos51° )

BC = [tex]\frac{8.6}{cos51}[/tex] ≈ 13.7 ( to 3 sf )

-x=-y-6
x+2y=12
a. (7,1)
b. (8,2)
c. (6,0)
d. (9,3)

Answers

Answer:

c. (6, 0)

Step-by-step explanation:

First, add y on both sides of the first equation, so it's easier to solve:

-x+y = 6

x+2y = 12

Then, add the 2 equations:

3y = 18

y = 6

Since c is the only one with a 6, we can deduce that the answer is c.

We can further check by plugging y back into the first equation:

-x+6 = 6

-x = 0

x = 0

This confirms that the answer is c.

Which inequality describes the graph
Y < 3/4x -3
Y _> 3/4x -3
Y _< 3/4x -3
Y > 3/4x -3

Answers

Answer: Choice B)  [tex]y \ge \frac{3}{4}x-3[/tex]

The boundary is the equation y = (3/4)x-3 which goes through (0,-3) and (4,0)

This boundary is a solid line. Since it's a solid line, we will involve "or equal to" as part of the inequality sign.

The shading above the boundary line indicates we'll also have "greater than" as part of the inequality sign.

So overall, the inequality sign is "greater than or equal to". That leads to choice B.

Hed been running for so long that he had pains in his side and his legs were beginning to hurt. He hunched over and tried to expand his lungs, but it was like trying to suck air out of a bicycle tire. His body was too exhausted to even allow him to take a deep breath, and he started to wheeze again.Great, he thought, let me just add asthma to my expanding list of ailments. I cant believe that I cant even jog two miles without completely collapsing! He finally gave in to his aching body and laid down on the grass to recuperate. He closed his eyes and tried to imagine himself running on the school track in the 1,600-meter race. He pictured himself running steadily toward the finish line, running effortlessly like a cheetah in the jungle. He was so lost in thought that he didnt even hear Meiya approach.Hey sleepyhead, what are you doing napping on Seans lawn in the middle of the day? Meiya asked playfully.Carlo quickly sat up, breathing normally now and feeling a little embarrassed. I am trying to get in shape to try out for track, but I cant even run two miles, he said dejectedly.Wait, how many months are you out of surgery? Didnt you just finish rehab last week? Meiya asked. You cant expect to run two miles the first day.It had been six months since Carlos surgery and he specifically remembered the doctor telling him he could start running after six months. But he thought about what Meiya had said and realized she had a good point. After his surgery, the doctor did say rehab would be crucial to his recovery but that it would take time for him to gain back full use of his leg. He thought about how a baby had to learn to walk before it could run. He remembered when his nephew was learning to crawl; within days it seemed like he was walking. Running didnt come right away, Carlo remembered. He realized it was the same with his therapy. The maximum he had run in the past month was one mile on the treadmill, so he realized that Meiya was probably right. He would have to work at building up his endurance and set more realistic goals for himself. As he thought about what he had already accomplished, he started to smile and felt like a weight was being lifted off his shoulders. He realized that he had run almost a mile and a half before his body started to protest and if he kept working hard, he could get back to where he was before his accident.Since when did you get so smart, Dr. Meiya? he teased.
