x = 6

set the two angles equal to each other
3x+7 = 6x-11
subtract 3x from both sides
7 = 3x-11
add 11 on both sides
18 = 3x
divide by 3 on both sides
6 = x

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)

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?

Answers

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.

What is inequality?

The phenomenon of unequal or unequal distribution of resources and opportunities among members of a given society is referred to as inequality. In different contexts and for different people, the concept of inequality may mean different things. In addition, there are distinct but interconnected economic, social, and spatial dimensions to inequality. The disjuncture between the moral ethics of equity and social justice, on the one hand, and the normative concept of "deservingness," on the other, adds complexity to debates about inequality.

Given equation of inequality for basket ball and soccer ball

y ≥ 2 + x

where  x is the number of basketballs, and y is the number of soccer balls on display,

situation says  the second number must be at least 2 more than the first number. Also, we are dealing with basket ball and soccer ball, so we won't have negative numbers (Choice E is out) or fractions (Choice B is out).

for choice A: x = 4 and y = 10 (10 is 6 more than 4)

for C: x = 14 and y = 12 (12 is 2 lee than 14 it is not correct)

for D: x= 10 and y = 12  (12 is 2 more than 10)

Hence the option A and D is correct representation for solutions.
