Answer:

Explanation:

Number of bulbs = 20

Success of a bulb lightning properly = 0.92

Success of a bulb not lightning properly = 0.08

We have to find the probability of atmost 3 bulbs not lightning properly -

The random Variable X follows binomial distribution

= 0.929385

Mean and variance of bulbs in a string that are not lightning properly is given by

Mean of binomial distribution or E(X) = n*p = 20*0.08 = 1.6

Variance of binomial distribution or V(X) = n*p*(1-p) = 20*0.08*0.92 = 1.472

allsm [11]

Answer:

$21

Explanation:

As we know that

The inventory should be recorded in the books of accounts by applying the lower value of cost or net realizable value

In the given case

The cost is $23

And, the net realizable value is

= Expected selling price - selling cost

= $36 - $15

= $21

So by comparing the cost and net realizable value, the net realizable value contains the lower value i.e $21 and the same is recorded on the balance sheet for inventory

iragen [17]

Answer:

d. perfectly elastic.

Explanation:

Demand is perfectly elastic if it at the current price, the product is sold out but if there is a change in price demand falls to zero. the demand curve is horizontal

Demand in perfectly inelastic if there is no change in quantity demanded regardless of the change in price.

If the absolute value of price elasticity is greater than one, it means demand is elastic. Elastic demand means that quantity demanded is sensitive to price changes.  

Demand is inelastic if a small change in price has little or no effect on quantity demanded. The absolute value of elasticity would be less than one

Demand is unit elastic if a small change in price has an equal and proportionate effect on quantity demanded.
