First of all, Rodger must be making some serious cash to have 47 cars. Going back to the question, he can not group the cars in more than 2 ways. He can only group it in 1 way, 47 groups of 1. Pls brainliest
If the antique's value increases over time, it must be growing (not decaying) in value.
We're told the value increases by 12.12%, which means that if the current value is

, then the value after 1 year is

. Each year, the value increases by the same factor, which means after 2 years, the value is

; after 3 years, the value is

; and so on.
Here

is the starting value of the antique. So the answer is the second choice.
Answer = 5.5
You just have to add all the numbers together to get the answer
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 )
