A volleyball team has 30 players: 12 freshman, 4 sophomores, 6 juniors, and 8 seniors. If two players are chosen to be captains for the next game, what is the probability that both players chosen are freshman?

.8

Step-by-step explanation:

you would take 12 over 30 and set that equal to x over 2. then multiply 12 times 2 which is 24 then divide 24 by 30 which is .8

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
