The diameter of a pipe is normally distributed, with a mean of 0.8 inch and a variance of 0.0025. What is the probability that t

fgiga [73]

Answer:

0.02275

Step-by-step explanation:

Standard deviation is the square root of variance

Standard deviation= Square(0.0025)= 0.05

Because of the normally distributed, the z- score for 0.9 inches is:

(0.9-0.8)/0.05= 2

-> P(x<= 0.9)= P(2) = 0.97725

-> P (x>= 0.9)= 1-0.97725 = 0.02275

Answer:

Step-by-step explanation:

$(3,10)=(x_1,y_1)\\\\m=5$

Substitute values into point-slope form:

$y-y_1=m(x-x_1)\\\\y-10=5(x-3)\\\\y-10=5x-15$

Collect like terms

$y=5x-15+10\\\\y =5x-5$
