(simple interest) I = $14,300.00
Answer:
Two-Factor ANOVA with replication
Step-by-step explanation:
Types of detergent used ( A,B,C ) = 3
Length of time for the washing cycle : A = 18 mins, B = 20 mins, C = 22 mins
number of laundry loads = 18
significance level = 5%
The alternative hypothesis for testing the interaction is a Two-Factor ANOVA with replication this is because the factors that have variations are the : The type of detergent and the length of time for a washing cycle while the load is constant for all.
1.40 x 21 passes = 29.40 for passes.
38.40 - 29.40 = 9.00
He spent $9.00 on the card
8.263-13.48= -5.217
I suggest using a calculator for math that is hard to work out in your head.
Answer:
- c(m) = 39.95 +0.35m
- 85 minutes over 500
Step-by-step explanation:
Let m represent the number of minutes used over 500. Then the cost of the cell phone plan is ...
c(m) = 39.95 +0.35m
__
For a cost of 69.70, the number of excess minutes can be found by solving ...
69.70 = 39.95 +0.35m
29.75 = 0.35m . . . . . . . . . subtract 39.95
29.75/0.35 = m = 85 . . . . divide by the coefficient of m
The number of minutes of usage over 500 is 85.
