Historical data for a local manufacturing company show that the average number of defects per product produced is 2. In addition

charle [14.2K]

Answer:

The probability that there will be a total of 7 defects on four units is 0.14.

Step-by-step explanation:

A Poisson distribution describes the probability distribution of number of success in a specified time interval.

The probability distribution function for a Poisson distribution is:

$P(X = x)=\frac{e^{-\lambda}\lambda^{x}}{x!}, x=0,1,2,3,...$

Let <em>X</em> = number of defects in a unit produced.

It is provided that there are, on average, 2 defects per unit produced.

Then in 4 units the number of defects is, $(2\times4)=8$ .

Compute the probability of exactly 7 defects in 4 units as follows:

$P(X = x)=\frac{e^{-\lambda}\lambda^{x}}{x!}\\P(X=7)=\frac{e^{-8}8^{7}}{7!}\\=\frac{0.0003355\times2097152}{5040}\\ =0.1396\\\approx0.14$

Thus, the probability of exactly 7 defects in 4 units is 0.14.

C) How long is the potato in the air? *hint set h=0*<br> if h=-2(t-3)2+32

Galina-37 [17]

Answer:

if you meant to put $(t-3)^{2}$ , then the answer is 7

Step-by-step explanation:

h=-2 $(t-3)^{2}$ +32

solve for t

0=-2 $(t-3)^{2}$ +32

subtract 32 from both sides

-32=-2 $(t-3)^{2}$

divide both sides by -2

16= $(t-3)^{2}$

find suare root of 16

4= t-3

add 3 to both sides

7 = t
