Answer:

Expected_A  = 1.36

Expected_B  = 1.54

Company A, as it has the lowest expected number of defective boards

Step-by-step explanation:

What is the expected number of defective circuit boards for company A?

To obtain this value, we multiply the probabilities of each, per the number of defective circuit boards

Expected_A = 0*(0.21) + 1*(0.3) + 2*(0.41) + 3*(0.08)

Expected_A  = 1.36

What is the expected number of defective circuit boards for company B?

Expected_B = 0*(0.18) + 1*(0.32) + 2*(0.28) + 3*(0.22)

Expected_B  = 1.54

Which company should be chosen for purchasing circuit boards?

Company A, as it has the lowest expected number of defective boards

I need help with this please
SpyIntel [72]

Answer:

n= -1.2

Step-by-step explanation:

I think because if you use slope equation to find the slope which is 3/5 and then you use point slop equation to find out what the equation would be. y=3/5x and then you substitue y for 18 and solve/simplify the equation to get -1.2.

What is the approximate area of the circle shown below?
svet-max [94.6K]

Answer:

A. 804 cm²

Step-by-step explanation:

Formula :

\boxed{A = \pi r^2}

A = 3.14 × 16²

A = 3.14 × (16 × 16)

A = 3.14 × 256

A = 803.84 cm²

A = <u>8</u><u>0</u><u>4</u><u> </u><u>cm²</u> (rounded)

So, the approximate area of the shown below is 804 cm² (A)

What is the similarity ratio of △WXY to △GEF?

Simplify your answer and write it as a proper fraction, improper fraction, or whole number.

If two triangles are similar, their similarity ratio is the ratio between a side length in the first triangle and the corresponding side length in the second triangle.
