Mathematics

Answer:

5/3

Step-by-step explanation:

The slope is the rise over run or the change in y over the change in x. One way to find the slope is through the formula, which is $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$ . To use this simply plug in the two points. In this case, the expression would be $\frac{10-5}{8-5}$ . This simplifies down to 5/3.

You and your friends have just measured the heights of your dogs. The heights are 600mm, 470mm, 170mm, 430mm and 300mm. Find out

Rufina [12.5K]

Answer:

To find the mean, you have to add all numbers together and divide them by the number of data points.

let me show what I mean:

The heights of the dogs are 600,470,170, 430,300.

Step-by-step explanation:

600+470+170+430+300.

1970.

Now we have to divide 1,970 by 5 ( because we are given 5 data points)

The mean is:

1970/5=394

Variance: First, arrange the data from least to greatest.

s2 = 27130

Standard Deviation: 164.71187

Use the distance formula to find the distance between each pair of points. Round your answers to the nearest hundredths place W

Elodia [21]

Answer:

The answer is

<h2>5.83 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

$d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

W (-3,-5) and T (2,-2)

The distance between them is

$|WT| = \sqrt{ ({ - 3 - 2})^{2} + ( { - 5 + 2})^{2} } \\ = \sqrt{ ({ - 5})^{2} + ( { - 3})^{2} } \: \: \: \\ = \sqrt{25 + 9} \\ = \sqrt{34} \: \: \: \: \: \: \: \: \\ = 5.830951$

We have the final answer as

<h3>5.83 units to the nearest hundredth</h3>

Hope this helps you

Widths of two similar rectangles are 21ft and 18ft. What is the ratio of the perimeter? Of the areas?

ad-work [718]

Ratio of perimeters is a : b:

21:18

Which reduces to: 7:6

Ratio of areas is a^2 : b^

2:

"7 ^2: 6^2"

Which simplifies to: 49:16

The answer is 7:6 and 49:36
