Step-by-step explanation:
a) The first approach is to sort the data in ascending or descending order. Next, we Identify the minimum grade and the maximum grade. We then list the stems based on the minimum and maximum. And we construct the stem and leaf diagram as show. The first digit represents the stem and the last digit represents the leaf.
As shown, all the grade are two digits value, with minimum as 06 and maximum as 98. In this case, the first stem is 0 and the last stem is 9.
Others (b & c) are just the usual calculations.

Answer:
her balance aka ADB would be 372.08
3-4x+5=16-4x =>>kick 1. -4x to right side =>>
8=16-4x+4x=>> 8=16 that means question is wrong lol
Question should be 3+4x+5=2(8-2x) or 3-4x+5=2(8+2x)
Then the answer will be 8x=8 =>> x=1 :)
The average number of pins he knocks down per role is about 7 1/3
10 + 9 + 7 = 22
22 divided by 3 = 7 1/3
so his pin total would probably be 44
