rohan bought 3.4 pounds of cashews on wednesday 2.5 pounds on thursday and 4 pounds on friday. he is going to divide them equall

kenny6666 [7]

First, you would add all the pounds he bought altogether, to know how much he bought, and how many pounds he will divide amongst his friends. That's 3.4 + 2.5 + 4 which equals to 9.9.

So he divides 9.9 pounds of cashews between himself and his two friends, and that makes it dividing 9.9 pounds between two people. That would simply make it : 9.9 ÷ 3, which equals to 3.3

Each friend will get 3.3 pounds of cashews.

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).

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