<h2>Answer:</h2>

1)x+.25+5+2=[x= - \frac{28}{5}]=[x=-5.6] EQUIVALENT

2)x-7+.25x+14=[x=-\frac{28}{5}]=[x=-5.6] EQUIVALENT

3)2x+5-0.75x=2=[x=-\frac{29}{4}]=[x=-7.25] IS NOT EQUIVALENT

1.25x+7=[x=-\frac{28}{5}]=[x=-5.6]

<h2>Answer: </h2><h3>1 and 2 are equivalent, 3 is not equivalent!</h3>

A pharmaceutical company receives large shipments of aspirin tablets. The acceptance sampling plan is to randomly select and tes
hammer [34]

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
