(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.
(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
Answer:
hello it's really urgent the question is to find x and y and pls help me very urgent and pls give with full method or I can't understand pls ...
The length of fenceshadow is 16.25 feet.
In general, the term "proportion" refers to a part, share, or amount that is compared to a total.
According to the concept of proportion, tworatios are in proportion when they are equal.
A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.
Given:
length of Shadow Height
8 20
12 x
18 y
z 6.5
Using proportion
8/12 = 12 / x
8x = 144
x= 144/8
x= 18
and, 8/ 20 = 18/ y
8y = 360
y = 360/ 8
y = 45
and, 8/20 = z/6.5
130 = 8z
z= 16.25
Hence, the length of fence shadow is 16.25 feet.
