Answer: 58

Step-by-step explanation:

From 10 AM to 1 PM the numbers are 161, 368, 842, and 1918

So now we find the difference between the numbers.

368 - 161 = 207

842 - 368 = 474

1918 - 842 = 1076

now it asked for the average so you add them together then divide by 3

which is (207+474+1076)/3 = 585.66666666....

Then it says to round to the nearest integer which is 586

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
