The area of the room is 125 square feet because 12.5 times 10=125 square feet. As a result, you will spend $187.5 for it cost $1.5 to buy one square foot of carpet, and now we need 125 square feet to cover the room which 125 times 1.5 to get 187.5. Hope it help!
Answer:
15 out 45 is the probability.
So out of 45 times he will hit 15 times.
Given that a random variable X is normally distributed with a mean of 2 and a variance of 4, find the value of x such that P(X < x)=0.99 using the cumulative standard normal distribution table
Answer:
6.642
Step-by-step explanation:
Given that mean = 2
standard deviation = 2
Let X be the random Variable
Then X
N(n,
)
X
N(2,2)
By Central limit theorem;


P(X<x) = 0.09


P(X < x) = 0.99





X -2 = 2.321 × 2
X -2 = 4.642
X = 4.642 +2
X = 6.642
