Answer:
Mean = 2
Standard deviation = 1.356
Step-by-step explanation:
We are given;
Probability of taxpayers that make mistakes when filling out forms: p = 0.08
Sample size; n = 25
In binomial distribution;
Means is;
μ = np
Thus;
μ = 25 × 0.08
μ = 2
Formula for standard deviation here is;
σ = √(np(1 - p))
σ = √(25 × 0.08(1 - 0.08))
σ = 1.356
The composition of 2 functions is B
Answer: 32 1/2 meters = 106.63 ft

Answer:
10
Step-by-step explanation:
Diameter is radius times 2
so 5 is r then diameter is 10
ANSWER
A. Right
EXPLANATION
A tangent to a circle touches the circle at only one point.
The point where a tangent and a radius meet at is called the point of tangency.
The tangent to a circle meets the radius of a circle at a right angle.
This is because the angle between the tangent and the radius of the circle is 90°
The correct answer is A.
