Answer:
Step-by-step explanation:
65 + 75 + 64 + 60 + 64 + 20 + 80 + 125 = 553
since there are 8 numbers in the data set, divide by 8
Ans: 69.125
The correct answer is 4
100=25/X
X=4
Answer:
1) 2 hours
2) 96 miles
Step-by-step explanation:
1) Eliot and William went hiking. They went at the same speed. Let x mph be their speed.
<u>Elliot:</u>
Distance = 8 miles
Speed = x mph
Time
hours
<u>William:</u>
Distance = 12 miles
Speed = x mph
Time
hours
It took Eliot
less than William, then
![\dfrac{8}{x}+\dfrac{2}{3}=\dfrac{12}{x}\\ \\\dfrac{2}{3}=\dfrac{12}{x}-\dfrac{8}{x}\\ \\\dfrac{2}{3}=\dfrac{4}{x}\\ \\2x=3\cdot 4\ \ [\text{Cross multiply}]\\ \\2x=12\\ \\x=6\ mph](https://tex.z-dn.net/?f=%5Cdfrac%7B8%7D%7Bx%7D%2B%5Cdfrac%7B2%7D%7B3%7D%3D%5Cdfrac%7B12%7D%7Bx%7D%5C%5C%20%5C%5C%5Cdfrac%7B2%7D%7B3%7D%3D%5Cdfrac%7B12%7D%7Bx%7D-%5Cdfrac%7B8%7D%7Bx%7D%5C%5C%20%5C%5C%5Cdfrac%7B2%7D%7B3%7D%3D%5Cdfrac%7B4%7D%7Bx%7D%5C%5C%20%5C%5C2x%3D3%5Ccdot%204%5C%20%5C%20%5B%5Ctext%7BCross%20multiply%7D%5D%5C%5C%20%5C%5C2x%3D12%5C%5C%20%5C%5Cx%3D6%5C%20mph)
So, William's hike was

hours long.
2) <u>Initially:</u>
Distance = 120 miles
Speed = 55 mph
Time
hours
<u>Final:</u>
Speed = 44 mph
Time
hours
Distance 
I think the 3rd one, please let me know if I'm wrong. I don't want to give others the incorrect answer.

Hi there
The formula of the future value of annuity ordinary is
Fv=pmt [(1+r/k)^(kn)-1)÷(r/k)]
Fv future value?
PMT monthly payment 608
R interest rate 0.06
K compounded monthly 12
N time 6years
So
Fv=608×(((1+0.06÷12)^(12×6)
−1)÷(0.06÷12))
=52,536.58...answer
Good luck!
