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.

Neko [114]

$\dfrac{3x-1}{4}=-\dfrac{5}{11}\ \ \ \ |cross\ multiply\\\\11(3x-1)=4\cdot(-5)\\\\33x-11=-20\ \ \ \ |add\ 11\ to\ both\ sides\\\\33x=-9\ \ \ \ |divide\ both\ sides\ by\ 33\\\\x=-\dfrac{9}{33}\\\\\boxed{x=-\dfrac{3}{11}}$
