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.

I=0.13x+1025 A textbook salesperson's monthly income depends on the amount of his sales. His monthly income is a salary of $1025

Snezhnost [94]

Answer:

l = 0.13x+1025

Step-by-step explanation:

Let the monthly sales be x

Monthly income = $1025 + 13% of monthly sales

Monthly income = $1025 + 0.13x

Since l represent the monthly income

l = 1025+0.13x

Rearrange

l = 0.13x + 1025

Hence the linear equation representing the statement is l = 0.13x+1025
