Step-by-step explanation:
The table shows the types of movies and the number of DVDs reented by customers at a Red Box in one
Based on the data in the table, what is the probability that a random customer will not rent a drama?
Answer:
A
Step-by-step explanation:
The probability that a random customer will not rent a drama is 4/5. Option B is correct.
What is probability?Probability can be defined as the ratio of favorable outcomes to the total number of events.
here,
Total number of rented DVDs = 25 + 36 + 52 + 12 = 125
Number of Drama movies = 25
The probability that a random customer will rent a drama.
P(D) = 25 / 125 = 1/5
Now,
The probability that a random customer will not rent a drama,
P(D)' = 1 - P(D)
= 1 - 1/5 = 4/5
Thus, the probability that a random customer will not rent a drama is 4/5. Option B is correct.

finding missing angles of triangles show your work
Answer:
angle = 50
x = 6
Step-by-step explanation:
solution for angle:
180-(70+60) = 50
solution for x:
8x+2=50 (subtract 2 from both sides)
8x=48 (divide both sides by 8)
x=6

The time required to complete a job varies inversely as the number of people working. It took 4 hours for 7 electricians to wire a building. How long would it have taken 3 electricians?
A. 1 hour 43 minutes
B. 5 hours 15 minutes
C. 7 hours 30 minutes
D. 9 hours and 20 minutes
Answer:
9 hours and 20 minutes: b
Step-by-step explanation:
4*60=240
7x240=1680
1680/3=560
560= 9 h 20 m
The time required when 3 electricians are working is 9 hours and 20 minutes.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
The time required to complete the job varies inversely with the number of people working.
This means that if the number of people working decreases, the time required to complete the job will increase.
We can use the formula for inverse variation to solve the problem:
t = k/n
where t is the time required to complete the job, n is the number of people working, and k is a constant of proportionality.
We can find k by plugging in the given values:
4 = k/7
k = 28
Now we can use the formula to find the time required when 3 electricians are working:
t = 28/3
t ≈ 9.33 hours
Converting this to hours and minutes, we get:
t ≈ 9 hours and 20 minutes
Thus,
The time required when 3 electricians are working is 9 hours and 20 minutes.

x = -3i, x = 2 and the third zero is x = 3iPolynomial is:
(x + 3i)(x - 3i)(x - 2) =(x² - 9i²)(x - 2) =(x² + 9)(x - 2) =x³ - 2x² + 9x - 182.

-2y - 10 = x
- 10x - y = -14
Answer:
x=2 and y=−6
sorry this is pretty long, I did not know if you needed the steps or not
Step-by-step explanation:
−2y−10=x;−10x−y=−14
Solve−2y−10=x for x
−2y−10=x
−2y−10+−x=x+−x
−x−2y−10=0
−x−2y−10+2y=0+2y
−x−10=2y
−x−10+10=2y+10
−x=2y+10
-x/-1=2y+10/-1
x=−2y−10
Substitute−2y−10 for x in−10x−y=−14
−10x−y=−14
−10(−2y−10)−y=−14
19y+100=−14
19y+100+−100=−14+−100
19y=−114
19y/19=-114/19
y=-6
Substitute−6 for y in x=−2y−10
x=−2y−10
x=(−2)(−6)−10
x= 2
x=2 and y=−6
