The mode of this set of data is 12
Answer:
They are 9, 5 and 8
Step-by-step explanation:
F(1) = (1)^3 + 2(1)^2 - 5(1) - 6 = 1 + 2 - 5 - 6 = -8; x = 1 is not a solution to the polynomial.
f(-1) = (-1)^3 + 2(-1)^2 - 5(-1) - 6 = -1 + 2 + 5 - 6 = 0; x = -1 is a solution to polynomial.
From the options, a or c has x = -1, both has x = , so lets check for x = 3
f(3) = (3)^3 + 2(3)^2 - 5(3) - 6 = 27 + 18 - 15 - 6 = 24; x = 3 is not a solution to the polynomial.
Therefore the solutions to the polynomial are x = -3, x = -1, x = 2

Answer:
$850
Step-by-step explanation:
The amount of interest earned is ...
I = Prt . . . . . on principal P at annual rate r for t years
Using the given values, the interest earned is ...
I = $2000·0.0425·10 = $850
The interest Rozlyn's account earns in 10 years is $850.
