Answer:
The required product is
Step-by-step explanation:
Consider the provided expression.
Open the parentheses.
Add the like terms.
Hence, the required product is
you can transform 4x + 12 = 9x - 3 again into a simpler form by subtracting 4x form both sides to get 12 = 5x - 3, if you subsit

Answer:
The probability that the HR director will select an employee who is not a multiple of 13 is
Step-by-step explanation:
* <em>Lets explain how to solve the problem</em>
- The probability of an event is the measure of the chance that the
event will occur
- The probability of an event A is the number of ways that event A can
occur divided by the total number of possible outcomes
- If P(A) is the probability of event A, is the probability that the event A
does not occur is 1 - P(A)
* <em>Lets solve the problem</em>
- An HR director numbered employees 1 through 50 for an extra
vacation day contest
∴ There are 50 employees
- The HR director will select an employee
- We need to find the probability of select an employees who is not
multiple of 13
* At first lets find the multiples of 13
∵ 13 × 1 = 13
∵ 13 × 2 = 26
∵ 13 × 3 = 39
∴ The multiples of 13 from 1 to 50 are 13 , 26 , 39
∵ There are 3 multiples of 13
∵ There are 50 numbers
∵ Probability of multiple of 13 =
∵ Probability of not multiple of 13 = 1 - P(multiple of 13)
∴ Probability of not multiple of 13 =
∴ Probability of not multiple of 13 =
* The probability that the HR director will select an employee who is
not a multiple of 13 is
Answer:
Step-by-step explanation:
The interquartile range is IQR is:
Where:
= third quartile
= first quartile
So the interquartile range is the difference between the highest quartile and the lowest quartile. In other words, it is the width of the box in the diagram.
So:
The R range is the difference between the highest value and the lowest. In other words:
Finally:
