I hope that uesful for u :)
We start by ordering the values.
5, 7, 8, 10, 13, 14, 17, 17, 21
Now we find the median(middle number).
Median(b): 13
(I added (b) for "base" since we need to take more medians)
The median now divides this data into two halves.
Now we take the medians of the two remaining halves.
Median(Half1): 7.5
Median(Half2): 17
Mark off the minimum and maximum.
Min: 5
Max: 21
Now graph!
Your median(Half1) is incorrect, since your median for the first half is 9. Since our median for the first half is 7.5, the answer would be Answer Choice C.
10. If it rained 7/10 of the days, 3/10 days did not receive rain.
90 days multiplied by 3/10 is 27.
It would not rain about 27 days in the 90 days.
11. x multiplied by 8 and a half equals 5.
(8 and 1/2)x = 5
x = .588235 which is about 6/10
12. C = 6/10 and D = 8/10 so the product would be 48/100 which is close to 5/10. This point is N.
Answer:
x= 4
m<ABC= 56
Step-by-step explanation:
since BD bisects, both sides of the angle are equal.
So we can set up an equation like this: <ABD=<CBD
(9x-8)=(5x+8) calculate for x
you'll find x=4
then put four into one of the angle equations
9(4)-8=28
now we know each side of the angle is 28, double it to find the whole (<ABC)
28+28=56
