Step-by-step explanation:
The mean and standard deviation are:
μ = p
σ = √(pq/n)
Given p = 0.12, q = 0.88, and n = 200:
μ = 0.12
σ = √(0.12 × 0.88 / 200)
σ = 0.023
Since the sample is large, it can be approximated with a normal distribution. Find the z-score:
z = (x − μ) / σ
z = (0.14 − 0.12) / 0.023
z = 0.87
Use a calculator or table to find the probability:
P(Z > 0.87) = 1 − 0.8078
P(Z > 0.87) = 0.1922
Answer:
A. y = 3x; 30 feet
Step-by-step explanation:
The person travels 75 feet in 25 seconds, meaning that he will travel 3 feet per second.
75/25 = 3
This means that the equation will be y = 3x. To find the the feet traveled after 10 seconds, plug 10 into the given equation and solve for y.
y = 3x
y = 3(10)
y = 30
The person will travel 30 feet.
Answer:
b=7
Step-by-step explanation:
2(3b-1)= 40
divide both sides by 2
3b-1 = 20
then add 1 to each side
3b = 21
then divide both sides by 3
b = 7
then check 2(3*7-1) = 40
