Let the amount Tom does = x

Then Larissa’s time would be 3x( 3 times the amount of Tom)

And Neal would also be 3x

The total of the 3 is 84 hours so as an equation you have:

X + 3x + 3x = 84

Combine like terms

7x = 84

Divide both sides by 7

X = 84/7

X = 12 hours

Tom = x, so Tom exercised for 12 hours.

NARA [144]

Answer:

1/376,992

Step-by-step explanation:

Assuming that the order at which the numbers are picked does not matter, the number of possible combinations of selecting 5 balls out of 36 is:

$n=\frac{36!}{(36-5)!5!}=\frac{36*35*34*33*32}{5*4*3*2*1}=376,992$

Since each event can only happen once, the probability of getting all five balls right is:

$P = \frac{1}{376,992}$
