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:
A. None of them are defective
True that's equivalent since none defective means 0 defective
Step-by-step explanation:
For this case we have a total of 13 computers and we define the event:
E= "At least one of them is defective"
When we say at last one means that can be 1,2,3,4,5,6,7,8,9,10,11,12 or 13
The complement for this case is E' ="None of them is defective"
Let's analyze one by one the possible options:
A. None of them are defective
True that's equivalent since none defective means 0 defective
B. None of them are free of defects
False thats note equivalent since that means all have defects and that's not the complement.
C. More than one of them are free of defects
False we are interested on the complement and on this case 1 or more defective is not the complement for this case.
D. All of them are defective
False the complement is defined as non of them defective and for this case is not the correct way.
Answer:
66
Step-by-step explanation:
complimentary angles add up to 90 so:
3x-6 + 2x +46 = 90
5x +40 = 90
5x = 50
x = 10
2(10)+46 = 66
3(10) - 6 = 24
