8 years because its uses 100l per load and you wash 100 per year you multiply and get 10,000 which divided by 1,00 its 10 so 10 x 5 = 50 so you save 50 per year and its 400 dollars more so 50 x 8 years will be 400

Answer:
I know the formula and believe I can answer the question, I just want to make sure I'm using the right probability,p from the equation bellow.
Using the equation: p(x)=(nx)px(1−p)n−x. I wanted to know if p=2/10?
Step-by-step explanation:
no steps just answer
Answer: If the time is 3 1/2 years (most reasonable assumption)
Her initial deposit was $160
Step-by-step explanation: The basic formula for simple interest is
<em>i = prt i </em>is interest, P is principal (deposit) r is the percentage (converted to a decimal) and t is time, the number of years.
For this question, you have to rearrange the equation to solve for p.
So divide both sides by rt and you have
p = i/rt
Substitute the values given
p = 36.40/(0.065)(3.5)
