11 = w - 12
11 + 12 = w -12 + 12
w = 11 + 12
w = 23
<h3>What would be the value of $150 after eight years if you earn 12 % interest per year? A. $371.39 B. $415.96 C. $465.88 </h3>
<em>The compound interest is applied, that is to say, each year the interest produced is accumulated to the outstanding capital and the interest of the next period is calculated on the new outstanding capital.</em>
The formula for calculating compound interest is:
Compound interest = Total amount of Principal and interest in future less Principal amount at present = [P(1 + i)ⁿ] – P
(Where P = Principal, i = nominal annual interest rate in percentage terms, and n = number of compounding periods)
[P(1 + i)ⁿ] – P = P[(1 + i)ⁿ – 1] = $150[(1 + 12/100)⁸ – 1] = $150[(1.12)⁸ – 1] = $150[2.47596317629 - 1] = $150[1.47596317629] = $221.39
Total amount = $150 + $221.39 = $371.39
Answer : A.) $371.39
X = number of students who are members.
<span>19-x is the number of people who are not members.</span> x number of people paid $11 for tickets and (19-x) number of people paid $13.$11x+$13(19-x)=$209 for the total cost of the tickets.
$11x+ $247-$13x=$209 $11x-13x = $209 - $247
$-2x = $-38
divide -2 by both sides
x=19, meaning that all of the students are members.

Answer: -0.81</h3>
Work Shown:
z = (x - mu)/sigma
z = (71 - 74)/(3.7)
z = -0.8108 approximately
z = -0.81
Answer:
7n-4;696
Step-by-step explanation:
I look at it as having ordered pairs (1,3), (2,10), (3,17), etc
looks like the y's increase by 7 for every increase of 1 in the x's, so the slope = 7
thus y = 7x + b
plug in (1,3) ----> 3 = 7 + b or b = -4
y = 7x - 4
in sequence terms: termn = 7n - 4
term100 = 7(100)-4 = 696
