Answer: 0.0791
Step-by-step explanation:
Given : The probability that a baseball player will get a hit in any one at bat is 0.250.
Let x be the first hit.
According to the geometric probability , the probability that x (th) trial is the first success =
, where p is the probability of getting success in each trial.
As per given p= 0.250
Then, the probability that he will get his first hit on his 5th at bat will be :

Hence, the probability that he will get his first hit on his 5th at bat is 0.0791 .
The answer is c because I checked the math on the paper.
The water should fill the aquarium to 1.5 feet
Solution:
Given that the directions for the aquarium say that it should be filled with 9 cubic feet of water.
This means volume of aquarium is 9 cubic feet
Given that aquarium is 2 feet wide and 3 feet long
To find: Height of aquarium
Since a aquarium is in shape of cuboid, we can use the volume of cuboid formula
<em><u>The volume of cuboid is given as:</u></em>
volume of cuboid = 
Where "l" is the length
w is the width
"h" is the height
Substituting the values, we get,

Thus the height of aquarium is 1.5 feet
Answer:
x = 3.
Step-by-step explanation:
2(x + 1) + 1 = 1 - 2(x - 7)
2x + 2 + 1 = 1 - 2x + 14
4x = 1 + 14 - 2 - 1
4x = 12
x = 3.
