Answer:frog 1

Step-by-step explanation:

Frog 1 jumps 80cm in 5 sec

Frog 2 jumps 15cm in 1 sec

The rule says each frog must cross the finish line which is 5m away to win the race

If Frog 1 jumps 80cm in 5 sec, then frog 1 jumps 80/5 = 16cm in 1 sec

Converting from cm to m

1 m = 100cm

For frog 1, 16cm = 15/100 = 0.16m

For frog 2, 16cm = 15/100 = 0.15m

Frog 1 takes 5/0.16 = 31.25 sec to run the finish line

Frog 2 takes 5/0.15 = 33.33 sec to run the finish line

So frog 1 will win the race

AlekseyPX

Answer:

0.42074

Step-by-step explanation:

In this question, we are asked to calculate the probability that a car will get less than 21 miles per gallon.

This is P(x < 21)

z = 21-22/5 = -1/5 = -0.2

Therefore the probability of getting less than 21 miles per gallon will be;

P(x<21) = P (z < -0.2)

= 0.42074
