1. IQR = Q3 - Q1 = 35 - 20 = 15
A. 15
3. The ages include 20 and 25 so A and C are out, and the ages are between the two ages
B. a >= 20 and a <= 25
4. With the addition of 30, there are now 14 dots. Therefore, the median will be the mean of the 7th and 8th dots from least to greatest on the number line. In this case, it would still be 22.
C. The median would stay the same.
Jones takes 8 hours , therefore in one hour he paints a fraction of 1/8
smith takes 6 hours, thus in one hour he paints a fraction of 1/6
When working together they paint a fraction of 7/24 in an hour.
After 2 hours they will have painted a fraction of (7/24) ×2 = 7/12
The remainder will be 5/12 which will be undertake by smith alone.
Smith will therefore take 5/12 ×6/1 = 2.5 hour or 2 hours 30 minutes

i cant tell, sorry.
I cannot see the file attached. Can you type it in.
The perimeter in 60 minutes is:
2 * pi * r
2 * pi * 8
50.26548246 inches
It moves from 12 to 2:
The perimeter will be:
(10/60) * (50.26548246)
Rewriting:
= (2/12) * (50.26548246)
= (1/6) * (50.26548246)
= 8.37758041
round to two-decimal places:
= 8.38 inches
Answer:
the top of the minute hand moves 8.38 inches
