The probability that a player will be asked a math question and then a music question is 0.03125

<h3>How to determine the probability?</h3>

The size of the sections are given as:

Music = 0.5

Sport = 0.5

Others = 1

So, the total size is:

Total = 0.5 + 0.5 + 1 + 1 + 1

Evaluate

Total = 4

The probability of asking a math question is:

P(Math) = 1/4 = 0.25

The probability of asking a music question is:

P(Music) = 0.5/4 = 0.125

The required probability is:

P(Math and Music) = P(Math) * P(Music)

This gives

P(Math and Music) = 0.25 * 0.125

Evaluate

P(Math and Music) = 0.03125

Hence, the probability that a player will be asked a math question and then a music question is 0.03125

Ulleksa [173]

Answer:

Step-by-step explanation:

sample size ( n ) = 2500 women ( computer and mathematical occupations )

Average earnings of sample ( X )= $75000 / year

standard deviation ( s )= $9500

a) knowing that the average earnings of men are $89,000/year,  the null and the alternative hypotheses that the average earnings of women match the average earnings of men in the population.

Given ; Ц = $89000

Null hypothesis ( H0) : Ц = $89000

Alternative hypothesis ( H1 ) : Ц ≠ $89000

The test is : one sample t test hypothesis

Becky needs to choose a new cell phone plan. She has 2 choices. Carolina Cell offers a monthly fee of $20.79 and $2.00 for each
Paladinen [302]

Answer:

4.2 gigabytes

Step-by-step explanation:

To find the answer, you need to write an equation where the cost of Carolina Cell is equal to the cost of Sanford Cell:

20.79+2x=22.89+1.50x, where x is the number of gigabytes used.

Now, you can solve for x:

2x+1.50x=22.89-20.79

0.5x=2.1

x=2.1/0.5

x=4.2

According to this, the answer is that both plans would cost the same  when 4.2 gigabytes are used.
