The number of surface flaws in a plastic roll used in the interior of automobiles has a poisson distribution with a mean of 0.07 flaw per square foot of plastic roll. assume an automobile interior contains 10 square feet of plastic roll. round your answers to four decimal places (e. g. 98.7654). (a) what is the probability that there are no surface flaws in an auto interior?

There is a 49.6585% probability that there are no surface flaws in an auto interior

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

In which

x is the number of sucesses

e = 2.71828 is the Euler number

is the mean in our unit interval.

In this problem

We have mean of 0.07 flaw per square foot of plastic roll. Assume an automobile interior contains 10 square feet of plastic roll. So

(a) What is the probability that there are no surface flaws in an auto interior?

This is

There is a 49.6585% probability that there are no surface flaws in an auto interior

i think it is 18

step-by-step explanation:

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
