Choice B) Commutative Property is the answer

The commutative property of addition says that we can add two numbers in any order. For example: 2+3 = 5 and 3+2 = 5.

In general, the rule can be written as x+y = y+x. The x and y are simply placeholders for numbers. You can think of them as empty boxes to write a number inside. In this case, we have 7.2 for one of the boxes and -5.5 as the other value in the other box.

If $5,000 is borrowed with an interest of 12.3% compounded semi-annually, what is the total amount of money needed to pay it bac

jarptica [38.1K]

Answer:

$7153.03

Step-by-step explanation:

To find the total amount after 3 years, we can use the formula for compound tax:

P = Po * (1+r/n)^(t*n)

where P is the final value, Po is the inicial value, r is the rate, t is the amount of time and n depends on how the tax is compounded (in this case, it is semi-annually, so n = 2)

For our problem, we have that Po = 5000, r = 12.3% = 0.123, t = 3 years and n = 2, then we can calculate P:

P = 5000 * (1 + 0.123/2)^(3*2)

P = 5000 * (1 + 0.0615)^6

P = $7153.029

Rounding to the nearest cent, we have P = $7153.03

ANSWER

The number of children between the ages of 9 and 15 who visited the park is
$20$

EXPLANATION

The number of children between the ages of 9 and 15 who visited the park are those within the age group 9 to 12 and 12 to 15.

We can from the graph that, the height of the bar that corresponds to the age group 9 to 12

$= 14$
and the height of the bar that corresponds to the age group 12 to 15

$= 6$

The sum of the two frequencies

$= 14 + 6 = 20$
