A. The domain is any real number.
The range is f(x) ≥ 0.5 (or 50%)
b. The formula is
f(x) = (3.5 + x) / (7 + x)
c. The domain is any number except -7. The range is any real number greater than 0.
Answer:
81π
Step-by-step explanation:
Area of a circle formula is :
. r stands for radius.
Radius is half of the diameter. To solve for the area of the circle, we must replace r with diameter/2 which is 9 (18/2 = 9).

Now, the question wants us to give the answer in terms of pi. So we are going to simplify the equation WITH PI. Meaning, we aren't going to multiply pi. So we will just simplify 9 squared to 81.
So in terms of pi the area is 81π
Answer:
242
Step-by-step explanation:
3*4/2*2 + 5*8*3 = 242
Answer:
3%
Step-by-step explanation:
2 : (2 + 9 + 16 + 12 + 8 + 6 + 4 + 2 + 1) = 1/30 ≈ 3.33% ≈ 3%
The z-score is defined as the number of standard deviations above the mean. Its formula is z = (x - mean) / (standard deviation). So if we are given that this player's height has a z-score of 4.10 relative to others, this means that his height is 4.10 standard deviations above the mean.
