IGNORE WORK ON PAPER PLS HELP3. A game at an arcade consists of a balloon that is inflated little-by-little during each round of play. The player wins. when the balloon pops. The amount of air (in cubic inches) that is needed to make the balloon pop can be modeled by a uniform distribution on the interval from 25 to 35 cubic inches of air.

(a) Draw a density curve to model the amount of air that is needed to make the balloon pop. Be sure to include scales on both axes.

(b) About what percent of the time will the balloon pop upon receiving at most 28 cubic inches of air?

(c) Find the first quartile (Q1) of this distribution.

4. The manager of the arcade wants to know how quickly players switch from one game to another. After conducting a
study, he concludes that the amount of time that people spend playing a game before switching to a different game can be modeled by a normal distribution with mean 2.1 minutes and standard deviation 0.4 minutes.
Sketch the normal density curve. Label the mean and the points that are 1, 2, and 3 standard deviations from the mean.

Answers

(a) To draw a density curve for the uniform distribution on the interval from 25 to 35 cubic inches of air, you can use a horizontal line segment that represents a constant density over that interval. The density should be 1 divided by the width of the interval, which is 35 - 25 = 10 cubic inches. Here's how you can represent it graphically

What is one quarter added to three eights answer

Answers

1/4 + 3/8 = 5/8

You always have to change the denominators (which are the bottom parts of the fraction) to be the same. To make it simple you do 8 as the denominators, 2 × 4= 8.
Now all you have to do is add 2/8 + 3/8= 5/8
Easy as pie! Hope I helped you :)

You have to make the denominators the same so 1/4 and 3/8, times 1 and 4 by 2 so intead of 1/4 you have 2/8 and 2/8 + 3/8 which makes 5/8, which is a prime number so cannot be simplified

State an equation you could use to find the value of x. Then find the value of x in simplest form.

Answers

You can use the Pythagorean Theorem:

a^2+b^2=c^2
x^2+x^2=(7√2)^2
2x^2=49*2 (combine like terms and square the 7√2)
x^2=49 (divide both sides by 2)
x=7 (square root both sides)

So the equation is 2x^2=98 (simplest form) and x=7

128 is 74% of what number if necessary round your answer to the nearest hundredth

Answers

74% * x = 128
x=128/74%
x=172.97 (nearest hundredth)

Steps:
1. Do a proportion
128/x=74/100
2. Do 128 times 100 which equals 12,800
3. Do 12,800 divided by 74 which equals 172.972
4. If you rounded to the nearest hundreth, your answer would be: 172.97
(Since the 2 after the 7 was below 5, you would round down to 7)

Solve: 16x2 − 81 = 0.x = 4, 9
x = −4, −9
x = 9 over 4, x = −9 over 4
x = 81 over 16, x = −81 over 16

Answers

If you would like to solve 16x^2 - 81 = 0, you can calculate this using the following steps:

16x^2 - 81 = 0
(4x - 9) * (4x + 9) = 0
1. 4x - 9 = 0 ... 4x = 9 ... x = 9/4
2. 4x + 9 = 0 ... 4x = - 9 ... x = - 9/4

The correct result would be: x = 9 over 4, x = −9 over 4.
