we need to find the probability of bad sound cards.

we are having 1000 computers so 1000 sound card will be there.

manager found that 4 sounds are defective out of 1000 sound cards.

P(D) of defective sound cards=n(D)/n(s)=4/1000=0.004

we know that 1 is the total probability.out of 0.004 is the failure.

If y varies directly as x, and y is 400 when x is randy is r when x is 4, what is the numeric constant of variation in this rela
juin [17]

The numeric constant of variation is 100

Step-by-step explanation:

Direct proportion means that increase in one variable cause increase in other variable

Here,

It is given that

y varies directly as x

y∝x

when the proportionality symbol is removed a proportionality constant is introduced

y = kx

Given that

y = 100 when x = 4

Putting the values

400 = k * 4\\k = \frac{400}{4}\\k = 100

The numeric constant of variation is 100
