Answer: The answer is provided below

Step-by-step explanation:

A histogram is a diagram which consist of rectangles whereby the area is proportional to frequency of a variable and the width is equal to class interval. A histogram is a commonly used graph that is used to show frequency distributions.

The cumulative histogram is a histogram whereby the vertical axis doesn't gives only the counts for a single bin, but gives the counts for that bin and all the bins for the maller values of a response variable.

Cumulative histograms are similar to normal histograms, but the main difference is that they graph cumulative frequencies unlike histograms that graph just frequencies.

A gondola (cable car) at a ski area holds 50 people. Its maximum safe load is 10000 pounds. A populationof skiers has a distribu

butalik [34]

Answer:

The probability that maximum safe load will be exceeded is 3.9%

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 190 pounds

Standard Deviation, σ = 40 pounds

We are given that 50 skiers are randomly chosen from this normally distributed population, hence, by central limit theorem:

Mean, μ = 190 pounds

Standard Deviation, $\sigma = \displaystyle\frac{40}{\sqrt{50}}\text{ pounds}$

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

a) P(maximum safe load exceeded)

$P( x > \frac{10000}{50}) = P( z > \displaystyle\frac{\frac{10000}{50} - 190}{\frac{40}{\sqrt{50}}}) = P(z > 1.767)$

$= 1 - P(z \leq 1.767)$

Calculation the value from standard normal z table, we have,

$P(x > 10000) = 1 - 0.961 = 0.039= 3.9\%$

Hence, the probability that maximum safe load will be exceeded is 3.9%

An event planner can set up 6 tables in 30 minutes. How many tables can the event planner set up in 4.5 hours?

adelina 88 [10]

First convert 4.5 hours to minutes

4.5 hours = 270 minutes

6:30 = ?:270

Divide 270 and 30

270/30 = 9

Then multiply 6 and 9

9*6 = 54

The event planner can set up 54 tables in 4.5 hours(270 minutes)

54 tables

A paper company needs to ship paper to a large printing business. The paper will be shipped in small boxes and large boxes. The

Tanzania [10]

x+y=23 and 10x+24y=426 can be used to determine the number of small and large boxes shipped where x represents the number of small boxes and y represent the number of large boxes.

Step-by-step explanation:

Given,

Volume of small box = 10 cubic feet

Volume of large box = 24 cubic feet

Total boxes shipped = 23

Combined volume = 426 cubic feet

Let,

x represent the number of small boxes.

y represent the number of large boxes.

x+y=23

10x+24y=426

x+y=23 and 10x+24y=426 can be used to determine the number of small and large boxes shipped where x represents the number of small boxes and y represent the number of large boxes.
