If you're finding the mean for row 1 and row 5, remember that the mean is the same as finding an average. You would add all the numbers together then divide by how many you added.

Let me show you:

Row 1: 6, 5, 2, 8, 6
Row 5: 2, 3, 2, 2, 4

Add all the numbers from row 1 and 5 together.

You will get a value of 40.

Now divide number by how many numbers you added together, in this case we would divide 40 by 10, because we added together 10 numbers.

40 / 10 = 4

Thus, your mean/average would equal 4.

I hope this helps!

Answer:

B. $5039.58

Step-by-step explanation:

compound interest formula: amount = p(1 + \frac{r}{n})^{nt}

p= principal ($2,300)

r= interest rate as a decimal (4% = 0.04)

n= number of times the principal is compounded per year (annually = onceper year so 1 time per year)

t= time in years (20 years)

new equation: amount = 2300(1+\frac{0.04}{1} )^{1*20}

That equation equals $2,739.58 which you add to the principal.

$2,739.58 + $2,300 = $5039.58

hope this helps :)
