A certain kind of sheet metal has, on average, 9 defects per 11 square feet. Assuming a Poisson distribution, find the probability that a 14 square foot metal sheet has at least 10 defects. Round your answer to four decimals.

The probability that there are at least 10 defects is 0,7067

Step-by-step explanation:

Using a rule of three, if there are 9 defects average per 11 square feet, then for 14 there should be 9/11 * 14 = 11.4545. Lets call X the total amount of defects per 14 square foots. The distribution of X is given by

We can compute the probability for X being equal to 0,1,2,3,4,5,6,7,8 and 9 and substract it from 1

Thus, P(X ≥10) = 1-(P(X <10)) = 1-0.2933 = 0.7067

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
