<u>Answer:</u>
<u>For a:</u> The probability of getting a red or blue ball is 0.48
<u>For b:</u> The probability of getting a white, blue or orange ball is 0.81
<u>For c:</u> The probability of getting neither white or orange ball is 0.48
<u>Step-by-step explanation:</u>
Probability is defined as the extent to which an event is likely to occurs. It is measured by the ratio of the favorable outcomes to the total number of possible outcomes.
.......(1)
We are given:
Number of red balls in a box = 12
Number of white balls in a box = 18
Number of blue balls in a box = 19
Number of orange balls in a box = 15
Total balls in a box = [12 + 18 + 19 + 15] = 64
- <u>For a:</u>
Number of favorable outcomes (ball must be red or blue) = [12 + 19] = 31
Total number of outcomes = 64
Putting values in equation 1, we get:
- <u>For b:</u>
Number of favorable outcomes (ball must be white or blue or orange) = [18 + 19 + 15] = 52
Total number of outcomes = 64
Putting values in equation 1, we get:
- <u>For c:</u>
Number of favorable outcomes (ball must be white or orange) = [18 + 15] = 33
Total number of outcomes = 64
Putting values in equation 1, we get:
Probability of getting a ball which is neither white or orange = [1 - (Probability of getting a white or orange ball)] = [1 - 0.52] = 0.48
Answer:
An equation in function notation for the total cost of the book club will be:
- y = 20x + 12
Step-by-step explanation:
Given that Genesis needs to pay $12.00 for entrance into the book club.
Per month fee = $20.00
We know that the slope-intercept form of a linear function is
where m is the slope and b is the y-intercept
As the rate of change is also called the slope.
The rate of $20.00 per month would be termed as the slope = m = 20
One time fee = $12.00, meaning the y-intercept = b = 12
Thus, the equation becomes
- y represents the total cost
- x represents the duration
- m represents the rate of change = m = 20
- b represents the y-intercept = b = 12
y = 20x + 12
Therefore, an equation in function notation for the total cost of the book club will be:
- y = 20x + 12
