Suppose that, for every lot of 100 computer chips a company produces, an average of 1.4 are defective. Another company buys many
Allisa [31]

Answer:

0.1665

Step-by-step explanation:

Given that on an average 1.4 are defective per 100 computer chips

If the tested lot contains more than three defects, the buyer will reject all the lots sent in that batch.

Let X be the no of defective items in 100 chips

X is Poisson with mean =1.4

i.e. the probability that the buyer will accept the lots

=P(X\geq 3)\\\\=0.16651

Answer is 0.1665

Both pyramids in the figure have the same base area as the prism. The ratio of the combined volume of the pyramids to the volum
defon
At first, I thought this was going to be a dog of a bear of a problem,
but then I fixated it with my steely burning gaze and it fell apart for me.

The volume of a pyramid is   (1/3) (base area) (height)

Each of these pyramids has the same base area and the
same height, so ...

      Volume of the lower pyramid = (1/3) (base area) (height)
      Volume of the upper pyramid = (1/3) (base area) (height)

Combined volume of both pyramids = (2/3) (base area) (height) .

Now, how do the pyramids relate to the rectangular prism ?

Their base area is  (length x width) of the prism, and
their height is  (1/2 the height) of the prism.

From here, we'll work with the dimensions of the prism ... L, W, and H .

Combined volume of the pyramids = (2/3) (L x W) (1/2 H)

                                                           =  (1/3) (L x W x H) .

Volume of the prism  =  (L x W x H)

The pyramids occupy 1/3 the volume of the prism.

The ratio is  1/3 .

A manufacturer of skis offered chain discounts of 10/5/4 to many of its customers. Joe Jones ordered skis that had a total list
expeople1 [14]
,Okay, so here is how to calculate the amount of the trade discount:

I: $149,500 * .10 (10%) = 14,950 (this is the 10% discount)
149,500 - 14,950 = 134,550 (how much it costs with a 10% discount)

II: 134,550 * .5 (5%) = 6727.50
134,550 - 6727.50 = 127,822.50

III: 127,822.50 * .4 (4%) = 5112.90

The amount of the trade discount is: $14,950 + $6727.50 + $5112.90 = 26,790.40 dollars.

Make y the subject of the formula x=a-2by squared
Dominik [7]

Answer:

y = ± \sqrt{\frac{a-x}{2b} }

Step-by-step explanation:

Given

x = a - 2by² ( subtract a from both sides )

x - a = - 2by² ( multiply through by - 1 to clear the leading negative )

a - x = 2by² ( divide both sides by 2b )

\frac{a-x}{2b} = y² ( take the square root of both sides )

y = ± \sqrt{\frac{a-x}{2b} }
