0.75 lbs.
Step-by-step explanation:
Okay, this one is more simple. To find the weight of each book, You have to solve this division problem:
15/20
If you divided it the other way around, you would be saying each book weighed 1.33 pounds. That wouldn't be correct because then you would have over 20 lbs. of books, when you only have 15.
So, the answer is 0.75 pounds.
Answer:
B) 1/8
Step-by-step explanation:
each child born has 50/50 to be a boy or a girl, so, we determine a Bernoulli process where p=0.5, and we need 3 out of 3 successes.
the probability will then be:
(0.5)³=0.125=1/8
Leeza can put 33 or less gallons of water in aquarium.
Step-by-step explanation:
Given,
Capacity of aquarium = 55 gallons of water
Water already in aquarium = 22 gallons
Let,
x be the number of gallons that can be added in aquarium.
As aquarium can hold 55 gallons of water, therefore, we cannot add more than 55 gallons of water.
Subtracting 22 from both sides
Leeza can put 33 or less gallons of water in aquarium.
