Answer:

The correct option is 3. The total number of different ways to answer a multiple choice test is 243.

Step-by-step explanation:

Total number of questions is 5. Each question has three options.

Total number of ways to answer the first question is 3.

Similarly, the number of ways to answer each question is 3.

Total number ways to answer a multiple choice test is

3\times 3\times 3\times 3\times 3=3^5=243

Therefore the correct option is 3. The total number of different ways to answer a multiple choice  test is 243.

pantera1 [17]
The decimals are the same and are equal to each other. It is just that one decimal has a 0 after the 6 and the other one does not. You can write it either way. So both would be equal and both would be correct!

Adrienne invested a total of $2900.00 in two simple-interest money market accounts. Account A paid 3% annual interest and accoun
Butoxors [25]

Solving the system of equations, it is found that Adrienne invested $1,366.67 in account A and $1,533.33 in account B.

<h3>System of equations:</h3>

The variables are:

  • Variable A: Amount invested in account A.
  • Variable B: Amount invested in account B.

The equations are:

a + b = 2900

0.03a + 0.05b = 133

From the first equation:

a = 2900 - b

Replacing on the second:

0.03a + 0.05b = 133

0.03(2900 - b) + 0.05b = 133

0.03b = 46

b = \frac{46}{0.03}

b = 1533.33

Then, on the <em>first </em>equation:

a = 2900 - b = 2900 - 1533.33 = 1366.67&#10;

Hence, Adrienne invested $1,366.67 in account A and $1,533.33 in account B.
