Answer:
24 years
Step-by-step explanation:
Let Christopher's age=c
Since Christopher is 20 years younger than Ishaan.
Ishaan's age=c+20
Fourteen years ago, Ishaan was three times as old as Christopher.
Their ages 14 years ago are:
For Christopher: c-14
For Ishaan: (c+20)-14
Therefore:
3(c-14)=c+6
3c-42=c+6
3c-c=6+42
2c=48
Divide both sides by 2
c=24
Christopher is 24 years old.
I believe the answer is 5040
Answer:
One-fourth times 32
Step-by-step explanation:
Yes, I know...31.3 rounded is 31, not 32. But it's closer than any other number.
Answer:
16%
Step-by-step explanation:
First we start by solving for the z score
We have the following information
x = 3.25
Standard deviation = sd = 2.25
Mean = 5.50
Z = (x - mean)/sd
z = 3.25 - 5.50/2 25
z = -1.00
If we look this up in the standard normal distribution table,
P(z<-1.00) = 0.1587
Which when approximated gives us
16%
Therefore approximately 16% of lobsters will have to be returned back to the sea.
