Answer:
$33.92
Step-by-step explanation:
First, we have to find how much the sale price for the tennis racket is before tax.
100% - 20% = 80% Marcus has to pay 80% of the original price.
80% * 40 = .8 * 40 = 32
Marcus has to pay $32 for the tennis racket before tax.
6% = .06 (tax percentage)
.06 * 32 = 1.92 ————> tax
Add the tax with the sale price.
32 + 1.92 = 33.92
Marcus has to pay $33.92 for the tennis racket.
I hope this helped and please mark me as brainliest!
The relative frequency table would look something like this

30 and younger | | |

Where the empty spaces would be for the actual count or the for relative percentages
Since we are given that the relationship between x and y
is linear. Therefore this means that the given equation takes the form of:
y = m x + b
where,
b is the y intercept of the equation
m is the slope of the equation
However we should take note that the slope m is directly
proportional to the coefficient of correlation. Since our coefficient of
correlation is negative, this only means that the value of y is decreasing with
increasing x, hence plot of y and x is descending with increasing x.
Furthermore, this also tells that for every 1 unit increase of x, there is a
0.75 units decrease of y.
the local maximum is at x = -2.2 and has a value of 72.576
Answer:
B. y = x - 2
Step-by-step explanation:
The sale price (y) is $2 less than the original price (x - 2).
To test this out, if a book's original price is $10..
x = 10
Using y = x - 2 and to test out if it works, we'll plug in x = 10 to discover y.
y = 10 - 2
y = 8
