Answer:

18, 24, 8, 3

Step-by-step explanation:

8a = 42 - 18

8a = 24

a = 24 / 8

a = 3

To check, plug 3 into the equation

8(3) = 42-18

24 = 24

Answer:

8a = 42 - 18

8a = 24

a = 24 ÷ 8

a = 3

Step-by-step explanation:

To find the steps to the equation, we must solve the equation.

Step 1: Subtract 18 from both sides.

  • 8a = 42 - 18
  • 8a = 24

Step 2: Divide both sides by 8.

  • a = 24 ÷ 8
  • a = 3

Therefore, the answers are 18, 24, 8, and 3.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

A test consists of 100 multiple choice questions, each with five possible answers, only one of which is correct. Find the mean a
TEA [102]

Answer:  Mean = 20 and standard deviation = 4

Step-by-step explanation:

Let x represents the success of getting the correct answer.

Here, the total number of trials(n) = 100

The probability of getting the correct answer, p = 1/5

Thus, the mean of the number of correct answer,

\mu_x= np

\mu_x= 100\times 1/5

\mu_x= 20

Now, the standard deviation, \sigma_x= \sqrt{n\times p\times (1-p)}

\sigma_x= \sqrt{100\times 1/5\times 4/5}

\sigma_x= \sqrt{16}

\sigma_x= 4

Thus, First option is correct.
