Answer:
y=6-3x
Step-by-step explanation:
first subtract 9x from 9x+3y=18
-9x -9x
so you get 3y=18-9x or 3y=-9x+18 then divide both sides by 3
so you get y=6-3x hope this helps :)
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: B
Step-by-step explanation:
X = total miles run
4.6 + 0.78 + 3.4 = x
8.78 = x......so he ran a total of 8.78 miles
