A travel agency created a pamphlet for a city. They chose the high temperature for 10 random days during the year to calculate the temperature for the entire year, as shown below. 62°F, 72°F, 89°F, 57°F, 89°F, 62°F, 72°F, 62°F, 89°F, 57°F

Assuming that the sample was representative of the daily temperature for the entire year, what was the mean daily temperature?
A.
72°F
B.
72.6°F
C.
71.1°F
D.
67°F
pls help me quicklyy

Let's see what to do buddy...

_________________________________

We have following equation for finding the slope of the lines using two points :

Where a and b are the points which the line through them.

_________________________________

A = ( 8 , 9 )

B = ( -2 , 4 )

Now just put the coordinates in the above equation :

_________________________________

A)

The answer is :

_________________________________

B)

First we must choose one of the A or B points.

I choose : B = ( -2 , 4 )

We need using the following equation:

It's the point-slope form of the line..

_________________________________

C)

We just need to simplifies the above equation to find the slope-intercept form.

Look :

Both sides plus 4

It's the slope-intercept form of the line.

And we're done.

Thanks for watching buddy good luck.
