Answer:
B.) 8x + 12
Step-by-step explanation:
Using the Distributive Property the 4 is multiplied by each number inside the parentheses
4*2x = 8x
4*3 = 12
8x+12
Sorry this took so long! I managed to do everything except for the parts involving standard deviation. (I tried but I couldn't quite figure it out.)

Answer: $106,300
<u>Step-by-step explanation:</u>
A = P(1 + r)
- A is the accrued amount (balance)
- P is the principal (initial amount)
- r is the rate --> convert to a decimal
Given: P = 96,812 r = 9.8% --> 0.098
A = 96,812(1 + 0.098)
= 96,812(1.098)
= 106,299.576
rounded to the nearest dollar is $106,300
Answer:
Step-by-step explanation:
x= money earned per hour working as a cashier.
y=money earned per hour working delivering newspapers.
We propose the following system of equations:
5x + 4y =77
6x + 3y=78
We solve the system by reduction method:
-6*(5x+4y=77) ⇒ -30x-24y=-462
5*(6x+3y=78)⇒ 30x+15y=390
---------------------------
-9y=-72 ⇒ y=-72 /-9=8
Now, we get the value of "x" replacing the value of "y" by "8" in any part of the equation above.
5x + 4(8)=77
5x+32=77
5x=77-32
5x=45
x=45/5=9
therefore;
money earned per hour working as a cashier= $9/ hour
money earned per hour working delivering newspapers=$8/hour
