From the whole population of automobiles, 30% fail emission test with normal performance of a car. A manufacture is selecting 15 cars to run through emission tests. Use the binomial cumulative distribution function to calculate the probability for each number of failures possible. From the distribution, how many cars can fail the test before we conclude there is a malfunction

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two

well if he bought them at 5 cedis each sold them at 7 cedis each then he would make a profit of 2 cedis of each book. if in total he made 150 cedis profit that means he sold 75 books. he lost 12 books at the start so that means he originally bought a total of 82 books.
