The following chart shows the number of concert tickets sold and the profit earned. What is the slope of the line through these points? a. -1/4
b. -1/2
c. 4
d. 2

C.) 4

Step-by-step explanation:

y2 - y1/x2 - x1

m = 160 - 80/60 - 40

m = 80/20

m = 8/2

m = 4/1

m = 4

A) Best line of fit is last diagram diagonal line. Explanation below.

B) The weight increased by 4 on average with 1 or 2 76 calorie intake increases and then decreased by 6 pounds with every 7 x 75 calorie intakes only to increase by 10 this 6 pound proves a 4 pound overall increase it just proved that calories energy levels created a rapid weight gain and loss sequence when higher calories are consumed in pony's and all active animals.

C) 4 pounds as energy levels are proved.

Equation k= 13 makes sense as √1720.75 = 41  √1867 = 43

where 13 divides x 3-1/2 into the lower group √1650 = √40.6201920232 = 6.4

3-1/2 = 2.5 x 4 = 10

Showing that 3x 4 used = 12 being the higher section numbers 'the last 3 values'

Step-by-step explanation:

Middle value is found when you actually draw it

Alternatively we grid this in order and separate the two data as independents this way we can see the middle values.

x axis = 3  3  4  7  7  8  9  13  15  17

                      < 75                 <75  (<32.5) <75             <75

y axis = 1500 1575  |  1650 1725 | 1800 1875 | 1950 2025| 2100

median = 1800-32.5 midpoint for line of fit is centre origin 0 to coordinate that matches 1867.5 = the median

We see this is somewhere between value 8 and 9 x axis

We check to see the shift of x in the sequence above shown as x axis

And see the numbers median is 10 numbers and 5.5th number is 7.5 is the median so the shift is actually on this number half way to 1867.5

1800- 1575 = 225 + 67.5 = 292.5

We half this value and find 292.5/2 = 146.75

We add this amount to 1574 + 146.75 =  1720.75

1867.5- 146.75 = 1720.75

And use point of origin 0 on the axis grid and consider >1720.75<  to be the exact median and slant the ruler in area of the 1867 and decide on a value being either.
