Fynjy0 [20]

A + c = 158......a = 158 - c
9.90a + 5.50c = 1265

9.90(158 - c) + 5.50c = 1265
1564.20 - 9.90c + 5.50c = 1265
- 4.40c = 1265 - 1564.20
-4.40c = - 299.20
c = -299.20/-4.40
c = 68 <=== 68 child tickets sold

A quiz consists of 40 multiple choice questions, each with five possible answers, only one of which is correct. If a student g

Artist 52 [7]

Answer:

8 and 2.529

Step-by-step explanation:

The computation of the mean and the standard deviation is shown below:

Given that

Total number of questions is n = 40

The Probability of correct answer is p = $\frac{1}{5}$

So, the probability of the wrong answer is q = $1 - \frac {1}{5}$ = $\frac{4}{5}$

Moreover, this is the binomial distribution

Based on the above information

The mean is

$= n \times p$

$= 40\times \frac{1}{5}$

= 8

Now the variance is

$= 40\times \frac{1}{5} \times \frac{4}{5}$

= $\frac{32}{5}$

So, the standard deviation is

$= \sqrt{\frac{32}{5} }$

= 2.529

hence, the mean and the standard deviation is 8 and 2.529 respectively
