Answer:
40 miles a day
Step-by-step explanation:
The difference in fixed charge is $20; the difference in mileage charge is $0.50 per mile. So it will take $20/$0.50 = 40 miles for the extra mileage cost to eat up the savings in fixed cost. At that mileage, both companies will charge the same amount:
A: 90 + 0.30·40 = 102
B: 70 + 0.80·40 = 102
Given:
6 male professores
9 female professores
5 male teaching assistants
6 female teaching assistants
Sol:.

N (professors)

N(Male)

N(professors and male)

N(professors OR male) = N(professors) + N(males) -N(professor OR male)

N(People to choose from)

Then probablitiy is:

Then the probability is 10/13
Answer:
26
Step-by-step explanation:
The two angles shown are a linear pair. Their sum is 180°.
(4z -8)° +(3z +6)° = 180°
7z = 182 . . . . . . . . . divide by °, add 2
z = 26 . . . . . . . . . . divide by 7
Exponential increase
150,000x(1.08)^x where x is years
150,000x(1.08)^3 = 188957
