9(.80) = 7.2(.80) = 5.76(.80) = 4.608. round it and it is 4.6 feet
For the set B= { 3, 5, 7, ,9 , 12, 17, } determine n(B)
n is asking for the count of numbers in the set.
Set B has 6 numbers.
n(B) = 6
-12.8 - (-7.4) + 16.7 Expand out the brackets
-12.8 + 7.4 + 16.7 Simply add all
= 11.3
A
<u>Answer:</u>
- There is a 41.7% chance that you got a blue ball.
<u>Step-by-step explanation:</u>
<u>Total number of blue balls/Total number of balls x 100 = Chance of getting a blue ball</u>
- => 5/12 x 100
- => 5/6 x 50
- => 5/3 x 25
- => 125/3
- => 41.7
Hence, <u>there is a 41.7% chance that you got a blue ball.</u>
