Answer:
$13.86
Step-by-step explanation:
$5.94 / 3 = $1.98
1 slice = $1.98
7 slices = $1.98 x 7 = $13.86
Answer:
9.33333333333
Step-by-step explanation:
Answer:
B.
Step-by-step explanation:
Given,
The time for set up the game =
minutes,
Also, the time for each level of game is
minutes,
If there are l levels of games,
Then the time taken in all levels of game =
<em>
</em>
Hence, the total time ( in minutes ) = Set up time + time in all level
=
We have 60-minute of free trial of the game,
So, the total time taken can not be exceed to 60 minutes,
= 
Which is the required inequality.
Option 'B' is correct.
Using the hypergeometric distribution, it is found that there is a 0.4286 = 42.86% probability of getting 2 of the same colour.
The marbles are chosen without replacement, hence the <em>hypergeometric </em>distribution is used to solve this question.
<h3>What is the hypergeometric distribution formula?</h3>
The formula is:


The parameters are:
- x is the number of successes.
- N is the size of the population.
- n is the size of the sample.
- k is the total number of desired outcomes.
In this problem:
- There is a total of 3 + 4 = 7 marbles, hence N = 7.
- Of those, 3 are blue, hence k = 3.
- 2 marbles will be taken, hence n = 2.
The probability of getting 2 of the same colour is the sum of P(X = 0), which is both red, with P(X = 2), which is both blue, then:



Hence:

0.4286 = 42.86% probability of getting 2 of the same colour.
