Answer:
Step-by-step explanation:
<u>Use the Pythagorean theorem:</u>
<u>Verify this for each line:</u>
1.
- 28² + 45² = 53²
- 2809 = 2809
- Yes
2.
- 33² + 56² = 64²
- 4225 ≠ 4096
- No
3.
- 36² + 77² = 85²
- 7225 = 7225
- Yes
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
a^2 = c^2 - b^2 = 64 - 4 =60
So a = the square root of 60.
Multiply 2/3 and 1/6
2*1= 2
3*18=54
simplify 2/54 = 1/27
