Step-by-step explanation:
1hr 60 minutes = 2.5hours ÷15minutes =0.16×60=9.6 which they will be allowed to do the game time
Answer:
Mean = sum of all elements/number of elements
= (7.5 + 10.5 + 5 + 4.5 + 3.5 + 7.5 + 4 + 10 + 7.5 + 5)/10
= 6.5
=> Option C is correct
Hope this helps!

This is how I would factor it
Answer:
-2 - 8 = -10
Step-by-step explanation:
Complementary angles add up to 90°
----------------------------------------------
Ratio
----------------------------------------------
7 : 3
----------------------------------------------
Find total parts :
----------------------------------------------
Total parts = 7 + 3 = 10
----------------------------------------------
Find 10 parts :
----------------------------------------------
10 parts = 90
----------------------------------------------
Find 1 part :
----------------------------------------------
1 part = 90 ÷ 10 = 9
----------------------------------------------
Find 7 parts :
----------------------------------------------
7 parts = 9 x 7 = 63
----------------------------------------------
Find 3 parts :
----------------------------------------------
3 parts = 9 x 3 = 27
--------------------------------------------------------------------------------------------
Answer: The ratio of the two angles are 63:27
--------------------------------------------------------------------------------------------
