I took this test the answer is 92.
A large interquartile range shows the range in values of the central 50% of the data.
Answer:
y=2/3x-16/3
Step-by-step explanation:
ok ill show you how to do one question since the rest will take too long so what you do is
equation is y=mx+b right
so you have slope and these points (2,-4) and m=2/3
y=2/3x +b right
now all you do is sub in x and y which are ur given points
-4=2/3 (2) +b
now you solve for b
-4 = 4/3 + b
-4-4/3 = b
-12/3 - 4/3 = b
-16/3=b so therefore
y=2/3x-16/3
2z−31=−9z+24
Add 9z to both sides.
2z−31+9z=−9z+24+9z
11z−31=24
Add 31 to both sides.
11z−31+31=24+31
11z=55
Divide both sides by 11.
11z/11=55/11
z=5
Given:
Nora has a day off every 4 day while Amirah has day off every 6 days .
Nora last day off was on 29 april while Amirah was on 1 may.
To find:
When they have same day off.
Solution:
Nora last day off was on 29 april and she has a day off every 4 day.
So, her off days are
29 april, 3 may, 7 may, 11 may, 14 may, ...
Amirah last day off was on 1 may and she has day off every 6 days .
So, her off days are
1 may, 7 may, 13 may, ...
From the above two lists of off days, it is clear that they have same day off on 7 may.
