Answer:
8.48528137423857
Step-by-step explanation:
The square root of 72 is 8.48528137423857 because Finding the square root of a number is the inverse operation of squaring that number. Remember, the square of a number is that number times itself. The perfect squares are the squares of the whole numbers. The square root of a number, n, written below is the number that gives n when multiplied by itself.

<em><u>The least amount of money you would need to invest per month is; $335</u></em>
<em><u>The anticipated rate of return on your investments is; 7%</u></em>

- Amount to have been saved at the end of 10 years ≥ $40,000
Number of years of savings = 10 years.
- We want to find out the least amount to be invested per month.
There are 12 months in a year. Number of months in 10 years = 10 × 12 = 120 months.
- Thus, amount to be saved monthly = 40000/12 = $333.33
- Since the minimum amount he wants to save after 10 years is $40000, then we need to approximate the monthly savings in order.
Thus;
Monthly savings ≈ $335
- Now, for the anticipated rate of return on the investment, we know from S & P's that the benchmark on good rate of return for investment is a minimum of 7%.
- From online calculator, the worth of the investment after 10 years based on 7% rate of return yearly would be $57626.

Answer:
None of the above
Step-by-step explanation:
To find the GCF of something find the prime factorization of each number, then see which numbers are the same. After that multiply the numbers that are the same.
(PF): Prime Factorization
A: PF - 1 PF - 2 · 3 (Since they don't have any numbers in common the GCF is 1)
B: PF - 2 PF - 3 (The GCF is also 1)
C: PF - 2 PF - 2 · 3 (Because they have 2 in common the GCF is 2)
D: PF - 3 PF - 2 & 2 (The GCF is 1)
None of the options have a GCF of 3. Therefore it is none of the above
Using a calculator, it is found that the correlation coefficient for this data is given by:
B. -0.901.
<h3>What is a correlation coefficient?</h3>
- It is an index that measures correlation between two variables, assuming values between -1 and 1.
- If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.
- If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.
To find the coefficient, which has symbol r², we input in a calculator the values of x and the values of y, hence:
r² = -0.901.
Which means that option B is correct.
