Answer:

x= 13

both angles are equal to 106

Step-by-step explanation:

8x + 2= 14x - 76

-8x +76 - 8x +76

78 = 6x

78/6 = 13

8 (13) + 2 = 104 + 2 = 106

14(13) - 76 = 182 - 76 = 106

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

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.

Determine if (3,-4) is a solution to y < 2x – 5.

spin [16.1K]

You would plug in the ordered pair into the equation.

1. Put the y value from the ordered pair in the y spot, and the x value in the x spot.

2. add up the x side

Does it equal the y side?

Im a bit confused as the question says “&lt” at least on my end? I’m not sure if that’s just the way it ended up being written or if it means something. Sorry if my answer doesn’t apply :(. But if it does, I hope it helps!
