1/2(5x-6)-1/3(9x-5)+1
5/2x-3-3+5+1 distribute
5/2x-6+5+1 combine like terms
5/2
Answer:
B. x ≤ 2.
Step-by-step explanation:
56 - 10x ≥ 20 + 8x
-18x ≥ -36
x ≤ -36/-18 = 2. ( Note that the inequality sign flips because we are dividing by a negative value).
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).

Answer:
$15.88
Step-by-step explanation:
19.99X0.25 = 4.9975
4.9975~5.00
19.99- 5.00
14.99X0.06~ 0.89
14.99+0.89
15.88
