By Hand
Step 1:
Put the numbers in order.
1, 2, 5, 6, 7, 9, 12, 15, 18, 19, 27.
Step 2:
Find the median.
1, 2, 5, 6, 7, 9, 12, 15, 18, 19, 27.
Step 3:
Place parentheses around the numbers above and below the median.
Not necessary statistically, but it makes Q1 and Q3 easier to spot.
(1, 2, 5, 6, 7), 9, (12, 15, 18, 19, 27).
Step 4:
Find Q1 and Q3
Think of Q1 as a median in the lower half of the data and think of Q3 as a median for the upper half of data.
(1, 2, 5, 6, 7), 9, ( 12, 15, 18, 19, 27). Q1 = 5 and Q3 = 18.
Step 5:
Subtract Q1 from Q3 to find the interquartile range.
18 – 5 = 13.
Answer:

Step-by-step explanation:
Given
---- 10 sided
--- 6 sided
Required

First, list out the sample space



--- total outcomes
The event that the outcome of both is greater than 4 is:


So, the probability is:



If 4 isn’t part of the question it would be out of 26 students 12 wear glasses so 12:26
Couch: 2x
love seat: 2x+400
chair: x
total amount: $1565
2x+2x+400+x=1565
5x+400=1565
5x=1165
x= 233
The cost of the chair is $233. The cost of the couch is $466. The cost of the love seat is $866.
Hope this helps!
The answer is n=15 because you have to simplify
