If the length of a rectangle is halved and its breath is tripled, what is the percentage change in its area??

Dennis_Churaev [7]

Answer:

A 50% increase

Step-by-step explanation:

Area = length x breadth

Let illustrate this with an example

original dimensions

length = 4

breadth = 5

area = 4 x 5 = 20

new dimensions

length = 4/2 = 2

breadth = 5 x 3 = 15

area = 15 x 2 = 30

Percentage change = 30 - 20 / 20 x 100 = 50%

Suppose a shipment of 120 electronic components contains 3 defective components. to determine whether the shipment should be ac

Likurg_2 [28]

For this problem, the most accurate is to use combinations

Because the order in which it was selected in the components does not matter to us, we use combinations

Then the combinations are $nC_r = \frac{ n! }{r! (n-r)!}$

n represents the amount of things you can choose and choose r from them

You need the probability that the 3 selected components at least one are defective.

That is the same as:

(1 - probability that no component of the selection is defective).

The probability that none of the 3 selected components are defective is:

$P = \frac{_{117}C_3}{_{120}C_3}$

Where $_{117}C_3$ is the number of ways to select 3 non-defective components from 117 non-defective components and $_{120}C_3$ is the number of ways to select 3 components from 120.

$_{117}C_3 = 260130$

$_{120}C_3 = 280840$

So:

$P = \frac{260130}{280840} = 0.927$

Finally, the probability that at least one of the selected components is defective is:

$P = 1-0.927 = 0.0737$

P = 7.4%
