7 0

Answer:

22years

Step-by-step explanation:

The sum of ages of people in the room is 40 * 5= 200

[ Remember mean = total ahead of people/ number of people]

Let the age of the 6th person be X

200+x. / 6 = 37

200 + x = 37 * 6 = 222

x = 222- 200 = 22

Find the distance between (-3,-1) and (4, 2). (Round up to the nearest hundredths.)
yanalaym [24]

Answer:

The answer is

<h2>7.61 units</h2>

Step-by-step explanation:

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

<h3>d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  }  \\</h3>

where

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

From the question the points are

(-3,-1) and (4, 2).

The distance is

d =  \sqrt{ ({ -  3 - 4})^{2}  +  ({ - 1 - 2})^{2} }  \\  =  \sqrt{ ({  - 7})^{2}  +  ({ -   3 })^{2} }  \\  =  \sqrt{49 + 9}  \\  =  \sqrt{58}  \\  = 7.615773

We have the final answer as

<h3>7.61 units to the nearest hundredth</h3>

Hope this helps you
