Butch has a collection of 80 vinyl records from throughout the 20th century including nine from the 40s, four from the 50s, eleven from the 60s, eight from the 70s, and 16 from the 80s. If he randomly selects one from his collection of 80, find the probability it will be from each of the following decades. The probability that it is from the 40s is

correct answer:

a + bi

step-by-step explanation:

a and d

nope lol

step-by-step explanation:

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
