P(the first song is a rock song and the second is a country song)=2/8×3/7=6/56=3/28
Answer:
x=-7 x=2
Step-by-step explanation:
x^2+5x-14=0
Factor
What 2 numbers multiply to -14 and add to 5
7*-2 = 14
7 -2 =5
(x+7) (x-2) = 0
Using the zero product property
x+7 = 0 x-2 =0
x=-7 x=2

Answer:
The final ballance will be $1300.37.
Step-by-step explanation:
In this case we have a compounded interest, in order to calculate the final balance we need to use the following formula:
S = P(1 + r/n)^(n*t)
Where S is the final balance, P is the initial investment, r is the rate of interest, t is the time and n is the rate at which it is compounded. Since we have all the values we can directly apply to the formula as follows:
S = 975.52*(1 + 0.0725/4)^(4*4)
S = 975.52*(1.018125)^(16)
S = 975.52*1.333
S = 1300.37
The final ballance will be $1300.37.
