Put numbers in order: 4,5,6,6,7,8,9,9,10,10,12,12,14,15
Cut the list into two equal parts: 4,5,6,6,7,8,9 and 9,10,10,12,12,14,15
Find middle numbers: 4,5,6,6,7,8,9 and 9,10,10,12,12,14,15
Lower quartile: 6
Upper quartile: 12
The difference of the values of the first and third quartiles of the data set is 12 - 6 = 6
Answer:
0.40
Step-by-step explanation:
to find out the probability that at least one of a pair of fair dice lands of 5, given that the sum of the dice is 8
Let A = sum of dice is 8
B = one lands in 5
P(B/A) = P(AB)/P(A) by conditional probability
P(AB) = sum is 8 and one is 5
So (5,3) or (3,5)
P(A) = sum is 8.
i.e. (2,6) (2,6) (3,5) (5,3) (4,4)
Required probability
= n(AB)/n(A)
=
Add the numbers together and divide it by 2. 1.5 + 7.1 is 8.6. Then divide by 2 to get 4.3
Answer:
A. 1%
B. 80%
C. 0.8, 8/10
Step-by-step explanation:
A. There are 100 blocks so each block is 1/100 which is 1%
B. As you can see, there are 80 blocks shaded so that would be 80/100 which is 80%
C. You can represent a percent as a decimal or a fraction
Hope this helped!
Kevin will have enough. He will need to pay $23.10.
5% of $22 is $1.10.
22+1.10=23.10
23.10 is less than 24
