Answer:
I getting the probability of the adult female that will rent the action movies in DVDs in by dividing the possible probability outcome which is 10% of all adults by the total number of possible outcome. So all of the population of the female is 51% and the ones who rent is only 10%. the probability is 19%
The solution is, 0.20 is the probability that the person rents action-movie DVDs, given that the person is female.
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
here, we have,
given that,
Data:
A: the adult is a male, P(A) = 0.49
B: the adult rent action-movie DVDs
C: the adult is a female, P(C) = 1 - P(A) = 1 - 0.49 = 0.51
24% of the adults are male and rent action-movie DVDs, then P(A ∩ B) = 0.24
10% of the adults are female and rent action-movie DVDs, then P(C ∩ B) = 0.10
The conditional probability of B (the adult rents action-movie DVDs) given C (the adult is female) is computed as follows:
P(B|C) = P(C ∩ B)/P(C)
= 0.1/0.51
= 0.2
Hence, The solution is, 0.20 is the probability that the person rents action-movie DVDs, given that the person is female.

Step-by-step explanation: The total should be 180 and its common sense to know that measure <5 is not 105 degrees
At a certain restaurant, 8 sandwiches and 10 burritos will cost $123.40. In addition, 5 sandwiches
and 9 burritos cost $97.20. Assuming that we are talking about the same sandwiches and burritos,
what is the cost of 1 sandwich? What is the cost of 1 burrito? Let x represent the cost of a
sandwich and y represent the cost of a burrito
Equation #1:
Equation #2:
Cost of 1 burrito:
Cost of 1 sandwich: $
Answer:
Equation 1: 8x + 10y = 123.4
Equation 2: 5x + 9y = 97.2
cost of a burrito = $7.30
cost of a sandwich = $6.30
Step-by-step explanation:
Let x = cost of a sandwich
Let y = cost of a burrito
Equation 1: 8x + 10y = 123.4
Equation 2: 5x + 9y = 97.2
Rewrite equation 1 to make y the subject, then substitute into equation 2 and solve for x:
8x + 10y = 123.4
⇒ 10y = 123.4 - 8x
⇒ y = 12.34 - 0.8x
5x + 9(12.34 - 0.8x) = 97.2
⇒ 5x + 111.06 - 7.2x = 97.2
⇒ 13.86 = 2.2x
⇒ x = 6.3
So cost of a sandwich = $6.30
Substituting x = 6.3 into equation 2 and solving for y:
5(6.3) + 9y = 97.2
⇒ 31.5 + 9y = 97.2
⇒ 9y = 65.7
⇒ y = 7.3
So cost of a burrito = $7.30
Answer:
8x + 10y = 123.40
5x + 9y = 97.20
OR
40x + 50y = 617
-40x - 72y = -777.6
x = $6.30
y = $7.30
Step-by-step explanation:
we can write this system of equations:
8x + 10y = 123.40
5x + 9y = 97.20
using the 'elimination method', we can multiply the first equation by 5 and the second equation by -8 to get:
5(8x + 10y) = 123.4(5)
40x + 50y = 617
-8(5x + 9y) = 97.2(-8)
-40x - 72y = -777.6
now we can add the new equations and solve for 'y':
40x + 50y = 617
-40x - 72y = -777.6
-22y = -160.6
y = 7.30
now we can substitute 7.3 for 'y' so we can solve for 'x':
8x + 10(7.3) = 123.4
8x + 73 = 123.4
8x = 50.4
x = 6.30
A small bus charges $3.50 per person for a ride from the train station to a concert. The bus will run if at least 3 people take it, and it cannot fit more than 10 people.
Function B gives the amount of money that the bus operator earns when n people ride the bus.
Which numbers make sense as inputs and outputs for this function?
i. 3-10
ii. 4-11
iii. 2-10

A circle is divided into 10 equal parts what is the angle measure of four of those parts
Answer:
Four of those parts will have 144 degrees
Explanation:
A full circle will always have 360 degree
If the circle is divided into 10 equal parts,
The angle shall divide in 10 parts:
Each slice angle: [tex]\frac{360}{10}[/tex] = 36 degrees.
1 parts has 36 degrees; so:
Four parts will have: 36 * 4 = 144 degrees.
Three vertices of a rectangle are (6,1), (3,1), and (3,8). What are the coordinates of the fourth vertex?
Answer:
Image result for Three vertices of a rectangle are (6,1), (3,1), and (3,8). What are the coordinates of the fourth vertex?
One would be to divide the rectangle into two triangles, then use the Pythagorean Theorem to find the distances between the points, and finally use Heron's formula to find the areas of the two triangles.
To find the area of a triangle where you know the x and y coordinates of the three vertices, you'll need to use the coordinate geometry formula: area = the absolute value of Ax(By - Cy) + Bx(Cy - Ay) + Cx(Ay - By) divided by 2.

2x+5y=-11
-8x-5y= -1
Answer:
x = 2 , y = -3
Step-by-step explanation:
by elimination method
+5y in equation 1 cancel -5y in equation 2
2x - 8x = -11 - 1
-6x = -12
divide both sides by - 6
- 6x/ -6 = -12/-6
x = 2
substitute x = 2 into equation ii
- 8 (2) - 5y = - 1
- 16 - 5y = - 1
collect like terms
- 5y = -1 + 16
- 5y = 15
divide both sides by -5y
-5y/-5y = 15/-5y
y = - 3

WILL GIVE BRAINLIEST!! In this triangle, what is the value of x? enter your answer, rounded to the nearest tenth, in the box.
x = 56.5 and rounded to the nearest tenth is still gonna be 56.5 but to the nearest TENS is 60 (Please give brainliest!!)
Step-by-step explanation:
His is a right triangle so you can use SOH CAH TOA :
Sine = opposite/ hypotenuse
Cosine= adjacent/ hypotenuse
Tangent = opposite/ adjacent
here you have the hypotenuse and are looking to solve for the adjacent side to angle measure 28
so you can set this up like this: cos(28)= x/64
now multiply both sides by 64 and you'll get x = 56.5 just make sure your calculator is in degrees not radians

Answer:
16 units squared
Step-by-step explanation:
First, calculate the distance between (0, 0) and (0, 4). The distance is in y, so there are 4 units in-between.
Next, calculate the distance between (0, 0) and (4, 0). This time, the distance is in x, but it is still four.
We know the dimensions of the shape are 4x4 so we just multiply.
