Answer:

25 nickels, 60 dimes and 20 quarters

Step-by-step explanation:

Nickels, dimes and quarters

Nickel= 5 cents, dime= 10 cents, quarter= 25 cents

equations we get:

n+d+q= 105

5n+10d+25q= 1225 ⇒ n+2d+5q= 245

if we subtract the first equation from the second we get:

d+4q= 140

considering d=3q, we have

3q+4q=140

7q=140

q=20

then

d=3*20= 60

n=105-(20+60)= 25

so there are 25 nickels, 60 dimes and 20 quarters

FrozenT [24]

We know that

In French club there are
10 freshman
12 sophomores
15 juniors
30 seniors

total of the members------> (10+12+15+30)=67
total freshman-----> 10

so
the probability that a freshman will be chosen=10/67
and
the probability that a freshman will not be chosen=(67-10)/67
the probability that a freshman will not be chosen=57/67---> 0.8507
0.8507= 85.07%

the answer is
the probability that a freshman will not be chosen is 85.07%
