Answer:
Option 1: 10r^2 - 36r + 32
Step-by-step explanation:
Option 1: 10r^2 - 36r + 32
First, you need to distinguish if this is a permutation or a combination. The difference between the two is the order. In combination, order does not matter. Since there is no any restriction given, we assume this is a combination problem. The equation of determining the number of ways to choose 'r' objects out of total 'n' objects is:
Number of ways = n!/r!(n-r)! = 15!/3!(15-3)! = 455
There are 455 ways.
Let p = peaches
Let m = mangos
We can now develop our system of equations in two variables, the variables chosen to be p and m.
7p + 5m = 16.00
10p + 4m = 14.50
Use the substitution method to find p and m.
Take it from here.
Answer:
9.007
Step-by-step explanation:
two thousandths= 0.002
nine ones= 9.0
five thousandths= 0.005
Add them all together, and you get 9.007
Answer:
y=1/3x+2
Step-by-step explanation:
y=3x-6
x=3y-6
3y=x+6
y=1/3x+6/3
y=1/3x+2
