Solve your equation step-by-step.
2700=2200(1+r)^5
Flip the equation.
2200(r+1)^5 = 2700
Divide both sides by 2200.
2200(r+1)^5 / 2200 = 2700 / 2200
(r+1)^5=27/22
Solve Exponent.
(r+1)^5=27/22
((r+1)5) ^1/5 = (27/22)^1/5 (Raise both sides to power)
r+1=1.041809
r+1−1=1.041809−1(Subtract 1 from both sides)
r = 0.041809
Check answers. (Plug them in to make sure they work.)
r = 0.041809 (Works in original equation)
The correct answer for the question that is being presented above is this one: "<span> C. The mean is decreased by about 1.2 and the median is decreased by 2." </span>For the data shown in the stem-and-leaf plot, the effect on the mean and median of adding the value 10 to the data set is that t<span>he mean is decreased by about 1.2 and the median is decreased by 2.</span>
-12 = 6 + 2/3y
Subtract 6 from both sides
-18 = 2/3y
Multiply both sides by 3
-54 = 2y
Divide both sides by 2
-27 = y
6 out of 10 or 3 out of 5
B or (0,-2) is the answer i would go with
