A shipment to a warehouse consists of 500 PS4. The manager chooses a random sample of 50 PS4 and finds that 3 are defective. How many PS4 in the shipment are likely to be defective?

Answers

Answer 1

Answer:

Answer:

30 PS4 in the shipment are likely to be defective

Step-by-step explanation:

We take the estimate from the sample and estimate to all the PS4 in store. This means that we can solve this question using a rule of 3.

From the sample of 50 PS4, 3 are defective. How many are expected to be defective out of 500?

50PS4 - 3 defective

500 PS4 - x defective

$50x = 3*500$

$x = (1500)/(50)$

$x = 30$

30 PS4 in the shipment are likely to be defective

What is the area of the trapezoid? If necessary, round your answer to the nearest tenth. A trapezoid with bottom side length of 8.5 feet, top side length of 5.5 feet, and height of 6.5 feet. 35.8 feet squared 45.5 feet squared 46.8 feet squared 55.3 feet squared

Answers

Answer:

45.5 sq. feet

Step-by-step explanation:

Area of trapezoid is given by 1/2(sum of parallel sides) * height of trapezoid.

In the problem

Parallel sides are bottom and top sides with length of 8.5 feet and 5.5 feet

Thus sum of Parallel sides = 8.5 feet + 5.5 feet = 14 feet

Height = 6.5 feet.

Thus,

area of trapezoid = 1/2*(14)* 6.5 feet = 7*6.5 feet = 45.5 sq. feet

The area of the trapezoid is whose sides are 8.5 feet and 5.5 feet with a height of 6.5 feet is 45.5 feet squared.

What is the area of a trapezoid?

A trapezoid is a quadrilateral with parallel opposite sides and a height.

Mathematically, the area of a trapezoid can be calculated by using the expression:

$\mathbf{Area \ of\ a \ trapezoid = (1)/(2)(a+b)* h}$

where:

a and b =the two parallel sides of the trapezoid
h = height

$\mathbf{Area \ of\ a \ trapezoid = (1)/(2)(8.5+5.5)* 6.5}$

$\mathbf{Area \ of\ a \ trapezoid = (1)/(2)(14)* 6.5}$

$\mathbf{Area \ of\ a \ trapezoid = 45.5 \ ft^2}$

a basketball team played six games. In those games, the team won by 8 points, lost by 14, won by 9, won by 10, lost by 1, and won by 6. What was the mean difference in game scores over the six games?

Answers

The mean of all the data will be equal to 8.

What is mean?

Mean is defined as the ratio of the sum of the number of data sets to the total number of data. Mean is generally the average it is calculated by adding all the data and dividing by the number of the data.

Given that a basketball team played six games. In those games, the team won by 8 points, lost by 14, won by 9, won by 10, lost by 1, and won by 6.

The mean of the data will be calculated as:-

Mean = ( 8 + 14 + 9 + 10 + 1 + 6 ) / 6

Mean = 8

Therefore, the mean of all the data will be equal to 8.
