Answer:
Compound interest
Step-by-step explanation:
Compound interest is a type of interest that is earned on both the principal plus any previous interest earned.
This ultimately implies that, the interest are compounded either on a daily, weekly, quarterly, monthly or annual basis.
Mathematically, compound interest is given by the formula;
Where;
A is the future value.
P is the principal or starting amount.
r is annual interest rate.
n is the number of times the interest is compounded in a year.
t is the number of years for the compound interest.
Answer:
X = 5 + (Gr)/3
Step-by-step explanation:
Step 1: Write equation
3X - Gr + 5 = 20
Step 2: Subtract 5 on both sides
3X - Gr = 15
Step 3: Add Gr to both sides
3X = 15 + Gr
Step 4: Divide both sides by 3
X = 5 + (Gr)/3
Answer:
number of gym members who prefer bicycling : 18/75*350 = 84
number of gym members who prefer exercise classes: 22/75*350 ≈ 103
number of gym members who prefer running on the treadmill: 15/75*350 = 70
number of gym members who prefer weight lifting: 20/75*350 ≈ 93
Step-by-step explanation:
GYM SURVEY RESULTS
Type Number of Members
Bicycling 18
Exercise Classes 22
Running on Treadmill 15
Weight Lifting 20
Total 75
Average rate of change means find the slope of the secant line. So if there is a function f(x) and you want to find the average R.O.C over the interval [a,b], it would be (f(b)-f(a))/(b-a)
1. (f(3)-f(1))/(3-1)= (0-(-2))/2= 1, so D.
2. Same concept; (8-4)/(3-1)=2, so A.
3. Again, (39-(-1))/5= 8, B.
