You would mutiple 22000 by 5 then divide that by .2 and that would be your answer
Answer:down there
Step-by-step explanation:
Start with 60 fliers
post 1/4 of fliers so 60*.25=15
60-15=45 left
post 1/5 of remaining so 45*.20=9
45-9=36 left
Have a great day!
Answer:
The IQR of the data set is 4.5
Step-by-step explanation:
Given:
10 13 15 12 12 4 12 17
12 13 15 18 10 11 20 19
Now, to determine the IQR (interquartile range) of this data set.
So, <em>we need to set the data in numerical orders:</em>
4 10 10 11 12 12 12 12
13 13 15 15 17 18 19 20
Now,<em> we split this in half and get the medians of both half:</em>
<u>4 10 10 11 12 12 12 12 </u> Median 1 = 11.5
<u>13 13 15 15 17 18 19 20 </u> Median 2 = 16
Getting the medians of both half now we subtract the median 1 from median 2:
IQR = 16 - 11.5
IQR = 4.5.
Therefore, the IQR of the data set is 4.5
Hey don’t worry about that grade just keep practicing maths and honestly at one point you’ll start understanding the concepts trust me. Just do it a lot.
So here are my explanations
Answer:
D
Step-by-step explanation:
the center is (0,8)
(to solve this just flip the signs on the constants being added to x and y (there is an invisible constant of 0 being added to the x))
the radius is 7 (or √49)
