What is the difference between the areas of a circular table with diameter 6ft and a circular table with diameter 8 ft ? Round y

miskamm [114]

Answer:

22 ft^2

Step-by-step explanation:

The area of a table with diameter 6 ft

A = pi r^2 = pi (6/2) ^2 = pi 3^2 = 9pi

The area of a table with diameter 8 ft

A = pi r^2 = pi (8/2) ^2 = pi 4^2 = 16pi

Subtract 16pi-9pi = 7pi

Using 3.14 for pi

7 * 3.14

21.98 ft^2

To the nearest square foot

22 ft^2

The data represent the age of world leaders on their day of inauguration. Find the five-number summary, and construct a boxplot

Mumz [18]

Answer:

Minimum value = 43, $Q_1=52$ , $Q_2=Median=61$ , $Q_3=67$ , Maximum value = 69.

Distribution is negative skewed.

Step-by-step explanation:

The given data set is

44, 43, 67, 68, 57, 65, 52, 62, 69, 54, 53, 61, 67, 48, 65

Arrange the data in ascending order

43, 44, 48, 52, 53, 54, 57, 61, 62, 65, 65, 67, 67, 68, 69

Divide the data in 4 equal parts.

(43, 44, 48), 52, (53, 54, 57), 61, (62, 65, 65), 67, (67, 68, 69)

Minimum value = 43

$Q_1=52$

$Q_2=Median=61$

$Q_3=67$

Maximum value = 69

Starting and end point of box plot represent the minimum and maximum value respectively. Box starts from the first quartile to the third quartile. A vertical line goes through the box at the median.

The shape of the distribution.

Normally distributed: If $Q_3-Q_2=Q_2-Q_1$

Positive skew: If $Q_3-Q_2>Q_2-Q_1$

Negative skew: If $Q_3-Q_2$

For the given data set

$Q_3-Q_2=67-61=6$

$Q_2-Q_1=61-52=9$

Since $Q_3-Q_2$ , therefore the given distribution is negative skewed.

Find the slope of the line containing the pair of points.

LenKa [72]

Answer:

Step-by-step explanation:

$my \: dear \: \\ to \: find \: the \: slope \: of \: a \: line \: use \: the \: formular \\ slope = \frac{y2 - y1}{x2 - x1} \\ from \: the \: question \: x1 = 5 \: \: y1 = 1\: \: x2 = - 5 \: \: y2 =- 9 \\ slope = \frac{ - 9 - 1}{ - 5 - 5} = \frac{ - 10}{ - 10} = 1 \\ therefore \: slope = 1 \\ hope \: this \: helps \\ stay \: focused \: with \: your \: studies$

Redo bc the last one was blurry

andrezito [222]

4. * 10^-9
4. * 10^10
6. * 10^7
4. * 10^-8
All rounded to the nearest whole number. Take the number given and move the decimal point to make the number less that 10 but greater than 1. The, count how many spaces you moved the decimal point, this will be the power of 10. If you moved the decimal point to the left, the power of 10 will be positive. If you moved it to the right, the power of 10 will be negative. Hope this helped!
