7 girls participated only in Karate.
21 + 8 = 29
29 + 7 = 36
36 + 6 = 43
Recall that 1 rotation is the equivalent of 360 degrees or 2pi radians.
7.5 rotations clockwise 2pi rad
------------------------------- * ---------------------------------------
1 1 rotation counterclockwise
= -47.12 radians, or -2700 degrees.
Answer:
Not rounded:
97% of 970.92 = 941.7924
Rounded to maximum 2 decimals:
97% of 970.92 ≈ 941.79
Step-by-step explanation:
Answer:b
Step-by-step explanation:y=2x-3
Answer: a is the # of elements in A but NOT B, that is A ONLY
b is the # of elements in B but NOT A, that is B only
N is the # of elements in the INTERSECTION of A and B
a + N = 99
b + N = 25
a + b + N = 123
Subtracting the first two equations: a - b = 74
Subtracting the last two equations: -a = -98
a = 98
So then a - b = 74 and a = 98
98 - b = 74
-b = -24
b = 24
a = 98, b = 24 and a + b + N = 123
98 + 24 + N = 123
122 + N = 123
N = 1
98 are in A only
24 are in B only , which is the answer to the question
1 is in both A and B
