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.

Answer:

7 $\frac{37}{55}$

Step-by-step explanation:

In order to solve an equation like this, you'll need to find a common denominator for your Fraction.

7 $\frac{2}{5}$ + $\frac{3}{11}$

7 $\frac{22}{55}$ + $\frac{15}{55}$

7 $\frac{37}{55}$

Which of the following is a factor of 10x2 − 19x 6? 5x − 3 5x − 2 2x 1 none of the above

kati45 [8]

I believe the correct answer from the choices listed above is the fourth option. The factor of the expression given as <span>10x^2 − 19x^6 would be 1 only. None of the other choices would factor correctly the expression. Hope this answers the question. Have a nice day.</span>
