Answer:
21
Step-by-step explanation:
First, add the parenthesis
2^4 + 4.50 ÷ 0.9
Second, divide 4.50 by 0.9
2^4 + 5
Third, get rid of the ^4
(2x2x2x2)
16 + 5
21
Answer:
0.219 or 21.028%
Step-by-step explanation:
0.18 are defective, so
P(x=1) = 0.18
P(x=2) = 0.18^2 = 0.0324
P(x=3) = 0.18^3 = 0.005832
P(x=4) = 0.18^4 = 0.00104976
Then add them together: 0.21928176
Answer:
do u still need the answer or no?
Step-by-step explanation:
Let M = #miles driven
Plan 1: .50M + 70 = total cost
Plan 2 .70M = total cost
To know how far she would drive to have an equal cost for either plan just set the equations equal to each other
.70M = .50M + 70
subtract .50M from both sides
.20M = 70
M = 70/.20 = 350 miles
Check the answser:
Plan 1: .50(350) + 70 = 175 + 70 = $245
Plan 2: .7(350) = $245
they are equal so our answer checks as correct
