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

Answer:
The correct answer is 30 miles.
Step-by-step explanation:
Porter is driving due east to point, say B, from his initial point, say A, for about 20 miles. Therefore AB = 20 miles.
He is driving due south to point, say C, from B, for about 23 miles. Therefore BC = 23 miles.
Therefore the distance between A and C is given by the Pythagoras theorem,
⇒ AC = = = 30.479 miles ≈ 30 miles.
Therefore Porter is 30 miles away from his initial point, to the nearest hundredth of a mile.
Answer:
15625
Step-by-step explanation:
Lets use the information to present the question into mathematical form:
so this means -5 is multiplying itself 6 times so this means
value of negative 5 superscript 6 means
= -5 x -5 x -5 x -5 x -5 x -5
so the answer is 15625
