Determine the size of sample space
Represent this with S
S is calculated by dividing the total number of kids by the number of selection.
<em>Hence, the sample space has a size of 4</em>
Answer:
(x+8, y+2) and reflect across x axis
Answer: .
Credit reporting agencies provide a free credit report each year upon request
Step-by-step explanation:
A credit report simply refers to the record of the credit history of a borrower from sources, such as collection agencies, banks, credit card companies, and governments.
It should be noted that an individual will be given one free copy of his or her credit report every year. Therefore, the correct option will be D.

Answer:
Yes, the normal curve can be used as an approximation to the binomial probability.
Step-by-step explanation:
Let <em>X</em> = number of students that pass their college placement exam.
The probability that a given student will pass their college placement exam is, P (X) = <em>p</em> = 0.53.
A random sample of <em>n</em> = 127 students is selected.
The random variable <em>X</em> follows a Binomial distribution.
But the sample size is too large.
A Normal approximation to Binomial can be used to approximate the distribution of proportion <em>p</em>.
The conditions to be satisfied are:
- <em>np</em> ≥ 10
- <em>n</em>(1-<em>p</em>) ≥ 10
Check whether the conditions are satisfied as follows:
Both he conditions are satisfied.
Thus, a normal curve can be used as an approximation to the binomial probability.
