Answer:
There are 795 combinations.
Step-by-step explanation:
The number of ways or combinations in which we can select k element from a group of n elements is given by:
So, if Miriam want to choose 3 movies with at least two comedies, she have two options: Choose 2 comedies and 1 foreign film or choose 3 comedies.
Then, the number of combinations for every case are:
1. Choose 2 Comedies from the 10 and choose 1 foreign film from 15. This is calculated as:
2. Choose 3 Comedies from the 10. This is calculated as:
Therefore, there are 795 combinations and it is calculated as:
675 + 120 = 795
Answer:
$26,000.
Step-by-step explanation:
We have been given that a job that pays $100,000 per year federal income taxes 19% and state income tax is 7%.
The annual total of the required deductions of federal and state income tax would be .
To find the total amount, we will find 26% of $100,000.
Therefore, the annual total of the required deductions of federal and state income tax is $26,000.
AND
b) solve g(x)=7 for x
For part a, we need to substitute 9 for x.
g(x) = 5 - 2/3(9). Simplify the right side of the equation.
g(x) = 5 - 6.
g(x) = -1
For part b, we need to solve for x by substituting 7 for g(x).
7 = 5 - 2/3x. Subtract 5 from both sides.
2 = -2/3x. Divide each side by -2/3.
-3 = x
Answer:
x = -4
Step-by-step explanation:
Since the slope is undefined, the line is a vertical line. All vertical lines have an equation x = k. In your problem k = -4, so the equation of the line is x = -4
Answer:
a = -21
Step-by-step explanation:
Multiply the equation by the reciprocal of the coefficient of 'a'.
(-7/6)(-6/7)a = (-7/6)(18)
a = (-7)(18/6) = (-7)(3)
a = -21
Answer:
I think the answer is a=-1/21
Answer:
Step-by-step explanation:
Given in the number of hours a group of contestants spent preparing for a quiz
The list shows as follows:
60 25 86 56 45 48 90 75 30 67 90 36 80 15 32 65 61
In ascending order this becomes
x 15 25 30 32 36 45 48 56 60 61 65 67 75 80 86 90
F 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 2
Thus we have mode =90
All other entries have frequency 1 except 90
