In order to achieve an average of 12 successful shots she has to score 36 times in total. So, she has to score 5 times in the 3rd set.
13 + 18 + 5 = 36
In order to achieve an average of 16 successful shots she has to score 48 times in total. So, she has to score 17 times in the 3rd set.
13 + 18 + 17 = 48
Express your answer in the form of a compound inequality using the variable F to represent a successful basketball free throw:
5 <= F <= 17
20% of 200 is 40, so H is the correct answers the proportion can be written as 40:200

Answer:
w = 1.5
Step-by-step explanation:
22(w + 2) = 77
22w + 44 = 77
22w = 77 - 44
22w = 33
22w/22 = 33/22
w = 1.5
Answer:
The height of the trapezoid is 6.63 units
The perimeter of the trapezoid is 38 units
Step-by-step explanation:
Whenever a geometry problem is given, it is often useful if it is sketched out. A sketch of this problem can be found in the image attached.
A)
We can see that a right-angled triangle is formed between points BED, with line BE being the height, h.
To get the dimensions of the line EB, we subtract the dimensions of DC from AB. This will give 15 -5 = 10
hence the dimensions of the righ angled triangle are
DE= h
DB = 12 (diagonal)
EB = 10
From Pythagoras' theorem,
The height of the trapezoid is 6.63
B)
We can get the perimeter of the trapezoid by adding the dimensions of all four sides together.
This will be
AD + DC + CB + AB
However we can assume for this case that it is a symmetrical trapezoid, and hence AD = CB
Thus, perimeter =
2 (AD) + DC +AB
2(9) +5 +15 = 38.
The perimeter of the trapezoid is 38 units
