Bill needs to earn $28 on Sunday so that the average is $22 each day, the correct option is C.
What is a Graph?
The graph is a mathematical representation of the relation between two objects.
Bill works as a waiter and he keeps track of the tips that he earns daily.
The tip earned on Monday is $14
The tip earned on Tuesday is $12.
The tip earned on Wednesday is $13.
The tip earned on Thursday is $25
The tip earned on Friday is $32
The tip earned on Saturday is $30
Average is the mean of the data set obtained by summing all the values of the data set and then dividing it by the number of data in the set.
The average money that he wants to make by tip is $22
Let the tip earned on Sunday is $x.
Then by the formula of average
22 = ( 14+ 12 + 13+ 25+ 32 + 30 +x ) / 7
Multiplying 22 by 7
154 = 14 + 12 + 13 + 25+ 32 + 30 +x
154 = 126 + x
x = $28

First thing you want to do is put it over 100
28/100
Now divide by 4
28÷4=7
100÷4=25

Hi!
Let's set up a proportion and cross-multiply.
5 x 20 = 100
100/1.25 = 80
The actual distance is 80 miles.
Hope this helps! :)

Answer:
C
Step-by-step explanation:
Direct variation is a special case of first order equations; in both cases, the input is multiplied by a constant which we call the "slope" or "constant of variation." However, no direct variation equation includes a constant ("y-intercept"). So, if a given equation does have a y-intersect, that equation does not represent direct variation; if it does NOT have a y-intercept, that equation represents direct variation.
A) involves a constant term, -2; NOT direct variation
B) involves a constant term, 10; NOT direct variation
C) Here 3y = x, or y = x/3, involves no constant term, so Does represent direct variation
D) involves a constant term -3; NOT direct variation

Answer:
M is 1 it is the slope. B is 2 it is where the slope crosses the y axis.
Step-by-step explanation:
y = mx + b
"m" is the slope, "b" is the y-intercept (the y value when x = 0) or (0,y)
y = mx
"m" is the slope (the y-intercept is 0/it crosses the origin (0,0))
When x = 0, y is 2, so the y-intercept is 2.
You can find the slope by using the slope formula and plugging in two points, or you use this:
Rise is the number of units you go up(+) or down(-)
Run is the number of units you go to the right.
If you look at the graph, from each point, you go up 1 unit, and to the right 1 unit. So the slope is 1/1 or 1.
y = mx + b
m = 1 and it represents the slope of the line
b = 2 and it represents the y-intercept of the line
y = 1x + 2 or y = x + 2
