5 degrees
Hoped that helped
For example, let's say b=30. If you divide 30 by 10, you get 3(obviously). But if you divide 10 into 30, you get -3.
Answer:
mean ≈ 25.45
Step-by-step explanation:
mean is calculated as
mean = 
We require the sum for both classes
class A
mean = 
= 40 ( multiply both sides by 9 )
sum = 9 × 40 = 360
class B
mean = 
= 20 ( multiply both sides by 24
sum = 24 × 20 = 480
Total sum for both classes = 360 + 480 = 840 , then mean for both classes is
mean = 
≈ 25.45 ( to 2 dec. places )
