Answer:
20 different total voting combinations.
Step-by-step explanation:
so lets called them A, B, C, D, and E
If John has to vote on his favorite and second favorite that means we will be selecting 2 bands out of the 5 possible to choose from.
To find the TOTAL amount of different combinations we need to pair up bands and find all the combo's.
Here are the results/totals:
AB
AC
AD
AE
BA
BC
BD
BE
CA
CB
CD
CE
DA
DB
DC
DE
EA
EB
EC
ED
If you want to do it simpler without listing you can take the the 5 bands and multiple by 4 since you know each initial band (A, B, C, D, and E) will be paired with another band other than itself.

The expression T = 15*3 + 32 could be used to correctly calculate the amount Roberta owes Mr. Jones
Step-by-step explanation:
Given that:
Amount charged for parts = $32
Per hour labor = $15
Time spent on repairing = 3 hours
Total amount = Per hour labor * Number of hours + Amount of parts
T = 15*3 + 32
Hence,
The expression T = 15*3 + 32 could be used to correctly calculate the amount Roberta owes Mr. Jones

Answer: The correct answer is Choice B, 12.3 years.
A z-score of about -0.523 would corresponding to the area which divides the normal distribution at 70% and 30%.
Now, we just need to write and solve an equation for that z-score.
(x - 15) / 5.2 = -0.523
x - 15 = -2.7196
x = 12.283
We can round it to 12.3 years old.
