Answer:

$Mean = 5.45$

Step-by-step explanation:

Given

$\begin{array}{cc}{x} & {f} & {0} & {1} & {1} & {2} \ \\ {3} & {1} & {4} & {2} & {5} & {6} & {6} & {7} & {7} & {6} & {8} & {5}\ \end{array}$

Required

Calculate the mean

Mean is calculated as:

$Mean = \frac{\sum fx}{\sum f}$

So, we have:

$Mean = \frac{0*1 + 1*2 + 2*1 + 3*1+4*2+5*6+6*7+7*6+8*5}{1+2+1+1+2+6+7+6+5}$

$Mean = \frac{169}{31}$

$Mean = 5.45161290323$

$Mean = 5.45$ -- approximated

Answer:

y=1/2x+13

Step-by-step explanation:

The slope-intercept form is: y=mx+b, where m is the slope and b is the y-intercept of the line. First, you have to calculate the slope using the following formula:

m=y2-y1/x2-x1

You have two points: (6, 16), (10,18) as the chores are the independent variable which is x, and the money is the dependent variable which is y.

Now, you can replace the values in the formula:

y2=18

y1=16

x2=10

x1=6

m=(18-16)/(10-6)

m=2/4

m=1/2

Now, you use the point-slope formula:

y-y1=m(x-x1)

You have to replace the value of the slope and one point and solve for y:

y-16=1/2(x-6)

y-16=1/2x-3

y=1/2x-3+16

y=1/2x+13

According to this, the answer is that the equation for his allowance in slope-intercept form is: y=1/2x+13.
