Rosa is correct, as 1 is not considered a prime no.
Answer:
0.9138 = 91.38%
Step-by-step explanation:
For each item, there are only two possible outcomes. Either it is defective, or it is not. The probability of an item being defective is independent of other items. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
10 items
This means that 
5 percent of the items shipped can be defective.
This means that 
Probability that a batch that meets the contract requirements will be shipped without further inspection
Probability of 1 or fewer defects.
So

In which




So the answer is:
0.9138 = 91.38%
First convert both distances to the same unit.
1 mile is 5280 feet or 1760 yards.
Subtract 1760-880 and get 880 yards.
Noah swam 880 yards further than Liam ran.
Answer:Coplanar line
Step-by-step explanation:
Answer:
The unknown number is 90
Step-by-step explanation:
This question requires a good understanding so as to interprets it well
And always ensure that all symbols used in representation are well stated so as to help the examiner or anyone who will mark it to understand better
So back to the question,let the unknown number be x
And two thirds of the unknown number is 2/3x
2/3x was decreased by 20 which can be written as 2/3x-20
And this decrease gives 40
That's,2/3x-20=40
Then go ahead to solve the question
Start by finding the LCM and the LCM is 3
2x-60/3=40
Cross multiply
2x-60=40×3
2x-60=120
Collect like terms by adding 60 to both sides
2x=180
Divide both sides by 2
x=90
Therefore the final answer is 90
