Listed below are the top 10 annual salaries (in millions of dollars) of TV personalities. Find the range, variance, and standard

larisa86 [58]

The range, variance and standard deviation of the is :

Range = 31.2
Variance = 152.978
Standard deviation = 12.368

Given the data :

39 37 35 27 19 16 13 9 8.6 7.8

Arranging in ascending order :

7.8, 8.6, 9, 13, 16, 19, 27, 35, 37, 39

Range = maximum - minimum values

Maximum value = 39

Minimum value = 7.8

Range = 39 - 7.8 = 31.2

The variance :

The variance : Σ(X - m)² / (n - 1)

m = mean

n = number of items

m = ΣX/ n = 211.4 / 10 = 21.4

Variance = [(39-21.14)^2 + (37-21.14)^2 + (35-21.14)^2 + (27-21.14)^2 + (19-21.14)^2 + (16-21.14)^2 + (13-21.14)^2 + (9-21.14)^2 + (8.6-21.14)^2 + (7.8-21.14)^2] / (10-1)

Variance = 1376.804 / 9

Variance = 152.978

Standard deviation = √variance

Standard deviation = √152.978

Standard deviation = 12.368

Two boys and three girls are auditioning to play the piano for a school production. Two students will be chosen, one as the pian

finlep [7]

Answer:

30% is the correct answer.

Step-by-step explanation:

Total number of boys = 2

Total number of girls = 3

Total number of students = 5

To find:

Probability that the pianist will be a boy and the alternate will be a girl?

Solution:

Here we have to make 2 choices.

1st choice has to be boy (pianist) and 2nd choice has to be girl (alternate).

$\bold{\text{Required probability }= P(\text{boy as pianist first}) \times P(\text{girl as alternate})}$

Formula for probability of an event E is given as:

$P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}$

For $P(\text{boy as pianist})$ , number of favorable cases are 2 (total number of boys).

Total number of cases = Total number of students i.e. 5

So, $P(\text{boy as pianist})$ is:

$P(\text{boy as pianist}) = \dfrac{2}{5}$

For $P(\text{girl as alternate})$ , number of favorable cases are 3 (total number of girls).

Now, one boy is already chosen as pianist so Total number of cases = Total number of students left i.e. (5 - 1) = 4

$P(\text{girl as alternate}) = \dfrac{3}{4}$

So, the required probability is:

$\text{Required probability } = \dfrac{2}{5}\times \dfrac{3}{4} = \dfrac{3}{10} = \bold{30\%}$
