Hello from MrBillDoesMath!
Answer:s:
For #18, see attachment, "Scatterplot_18", where the data is plotted. It looks like choice J -- no association-- is the correct answer.
For #14 it looks like you had some confusion but are on the right track. The formula for compound interest is Amount = P(1+r)^n, where P if the Principal (initial investment), r is the yearly rate, and "n" is the number of years invested. In your case,
A = 1000 ( 1 + .02)^3 => as 2% = 2/100 = .02; n = 3 as money
invested for three years
A = 1000 (1.061208) =
$1061.21
This is the same answer you got but is NOT one of the choices. Hmmm.....
Thank you,
MrB
Answer:
<em>The retail price of the jeans was $81.25.</em>
<em>Second Choice: $81.25.</em>
Step-by-step explanation:
Mrs. Jimenez paid $65 for some jeans.
She intended to sell them at her store by marking their price up by 25%.
We have to add 25% to $65:
25 * $65 / 100 = $16.25
$65 + $16.25 = $81.25
The retail price of the jeans was $81.25.
Second Choice: $81.25.
Answer:
- b = P - a - a - B
- b = P - 2a - B
Step-by-step explanation:
The perimeter is the sum of the lengths of the sides, so is ...
P = B + a + b + a
Subtracting the terms that are not "b" from both sides of the equation, you get
P - a - a - B = b
Swapping sides of the equal sign, this matches the first choice:
b = P - a - a - B
The two "-a" terms are "like terms" so can be added together. The result matches the second choice.
b = P - 2a - B
