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

Answer 1

Answer:

(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

Simplify 7 square root 2535

Answers

Answer:

The value of 7 square root 2535 is 352.443 or $91√(15)$ .

Step-by-step explanation:

Consider the provided expression.

$7√(2535)$

The value of $√(2535)$ is 50.349 approximately or 13√15

Now substitute the value of $√(2535)$ in above expression.

$7* 50.349$ or $7* 13√(15)$

$352.443$ or $91√(15)$

Hence, the value of 7 square root 2535 is 352.443 or $91√(15)$ .

7*sqrt(3*5*13^2) = 91*sqrt(15) = 91*3.872983346 = 352.4414845

Julia enjoys shooting paper balls into the wastebasket across her office. She misses the first shot 50% of the time. When she misses on the first shot, she misses the second shot 20% of the time. What is the probability of missing two shots in a row

Answers

First, convert the percentages into fractions. Since Julia misses 50% of her first shots, she misses 1/2 of her first shots. Since she misses 20% of her second shots (after missing the first one), she misses 1/5 of her second shots.

To find the probability of missing two shots in a row, multiply the two fractions together:

1/2 x 1/5 = 1/10

1/10 correlates to 10%. So, Julia has a 10% probability of missing two shots in a row.

10%

What can be multiplyed by 3 to equal 40

Answers

Let's say that the number we are looking for is called 'x'.

3 * x = 40
3x = 40

To solve for 'x', we will need to divide both sides by 3.

3x/3 = 40/3

$x = \boxed{\bf{(40)/(3) = 13(1)/(3)}}$

40/3 or 13 1/3 can be multiplied by 3 to get 40.
