8. Mitchell bought 600 shares of Centerco two years ago $34.50 per share. He sold them yesterday for $38.64 per share.

g100num [7]

Answer:

a. percentage increase in price per share = 12%

b. The total purchase price for the 600 shares is $20,700

c. The profit for the 600 shares is $2,484

d. The profit for the 600 shares is $2,484

Step-by-step explanation:

a. Initial price per share = $34.50

Current price per share = $38.64

Change or increase in price = $38.64 - $34.50 = $4.14

percentage increase in price per share = 12/34.50 x 100% = 12%

b. Total number of shares = 600

Price = $34.50

The total purchase price for the 600 shares = ($34.5x600) = $20,700

c. Total cost of 600 shares = ($34.5x600) = $20,700

Total revenue from sales = ($38.64x600) = $23,184

Profit from the 600 shares = Total selling price - total cost price

= $23,184 - $20,700 = $2,484

d. Total cost of 600 shares = ($34.5x600) = $20,700

Total revenue from sales = ($38.64x600) = $23,184

Profit from the 600 shares = Total selling price - total cost price

= $23,184 - $20,700 = $2,484

A pharmaceutical company receives large shipments of aspirin tablets. The acceptance sampling plan is to randomly select and tes

DerKrebs [107]

Answer:

a) The probability that this whole shipment will be accepted is 30%.

b) Many of the shipments with this rate of defective aspirin tablets will be rejected.

Step-by-step explanation:

We have a shipment of 3000 aspirin tablets, with a 5% rate of defects.

We select a sample of size 48 and test for defectives.

If more than one aspirin is defective, the batch is rejected.

The amount of defective aspirin tablets X can be modeled as a binomial distribution random variable, with p=0.55 and n=48

We have to calculate the probabilities that X is equal or less than 1: P(X≤1).

$P(X\leq1)=P(X=0)+P(X=1)\\\\\\P(0)=\binom{48}{0}(0.05)^0(0.95)^{48}=1*1*0.0853=0.0853\\\\\\P(1)=\binom{48}{1}(0.05)^1(0.95)^{47}=48*0.05*0.0897=0.2154\\\\\\P(X\eq1)=0.0853+0.2154=0.3007$
