The model that you could use to find the probability is a binomial model with parameters n = 3, X = 3 and p = 0.45.
For each TV bought, there are only two possible outcomes, either it is wide screen, or it is not. The probability of a TV bought being wide screen is independent of any other TV, hence the binomial distribution is used to solve this question.
What is the binomial probability distribution?It is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.
In this problem:
45% of its customers buy a wide-screen television, hence p = 0.45.The experimental probability that the next three television-buying customers will buy a wide-screen television is P(X = 3) when n = 3.More can be learned about the binomial distribution at https://brainly.com/question/24863377

P'(8,-2) is the image of P after a 180° rotation about the origin. What are the coordinates of P?
Answer:
-8,2
Step-by-step explanation:
180 Rotation formula: -x,-y
Given: 8,-2
Apply: -x,-y
Outcome: -8,2
based on the diagram given, find the value of x and y
Answer:
x = 6 , y = 2
Step-by-step explanation:
81x + 10 = 5y + 486 ............ (1)
9x + 40 = 20y + 54 ............ (2)
(1) × 4 - (2)
315x = 1890
x = 6 -------> (2)
9(6) + 40 = 20y + 54
20y = 94 - 54
y = 2
given data 4,x,9,5,2,7 find x if the mode is 4
Answer:
x = 4
Step-by-step explanation:
This is because the definition of mode is the number that appears the most or is the popular of the numbers in the data set.
This could be any number since each number is listed once, but the requirements/directions say the mode is 4 so you need another 4 in order to have a mode of 4.
Bella is typing a 400 word essay. She types 50 words in 2 minutes.
Enter an equation in the form of y=mx+b, that represents the number of words (y) remaining to type after x minutes.
Answer:
[tex]y=25x[/tex]
Step-by-step explanation:
If Bella types 50 words in 2 minutes, we can divide 50 by 2 to see how many words she types in 1 minute.
[tex]50/2=25[/tex]
So, Bella types 25 words per minute. When she first began writing her essay, she did not have words to start with, so there is no y-intercept ([tex]b[/tex]).
Therefore, the equation that represents this relation is [tex]y=25x[/tex].
Solving the equation
We can divide 400 by 25 to determine how many minutes it would take her to finish her essay.
[tex]\frac{400}{25} =16[/tex]
Therefore, it will take her 16 minutes to complete her essay.

All the line segments of this 22-gon meet at right angles. The radius of the smallest circle that will completely surround the polygon is
Answer:
√61 ≈ 7.81
Step-by-step explanation:
It appears that the polygon can be enclosed by a rectangle that is 12 units wide and 10 units high. The enclosing circle is the one that will circumscribe that rectange. Its radius is half the length of the diagonal, so is ...
(1/2)√(12² +10²) = 1/2√244 = √61
The smallest circle that will surround the polygon will have a radius of √61 ≈ 7.81 units.
_____
The Pythagorean theorem is used to find the length of the diagonal. It tells you the square of the diagonal is the sum of the squares of the sides of the rectangle. Our radius is half the diagonal, so is half the square root of the sum of the squares of the side lengths.

meters west of Jenna. How far does Lillian need to throw the ball to get it to Jenna? If
necessary, round to the nearest tenth.
meters
Submit
Answer:
8.2 meters
Step-by-step explanation:
This problem will form a Right angle triangle.
Where;
6.4 m and 5.2 m are the adjacent and opposite sides of the triangle while the distance that Lillian needs to throw the ball to get it to Jenna is the hypotenuse of the right angle triangle. Thus;
h = √(6.4² + 5.2²)
h = √68
h = 8.2

Step-by-step explanation:
To determine how to round up or down, we look at the place after the one we want to round to. In this case, we look at the tenths place.
If the tenths place is [tex]\geq 5[/tex] then you round up, and if it is [tex]\leq 4[/tex] you round down.
We see that the number is five and we round up to 426

Answer:
(x = 0,y = 0),(x = 1, y = 5),(x= 2, y =10)
Step-by-step explanation:
the rule is to multiply x by 5.
when x = 0, y =5(0) = 0
when x = 1, y =5(1) = 5
when x = 2, y =5(2) = 10

Step-by-step explanation:A table can be completed by plugging x-values into an equation or by graphing.
Plug in x-values
First, plug 0 into the equation to find the first y-value.
y=5(0)y=0Next, plug in 1 for x
y=5(1)y=5Finally, plug in 2
y=5(2)y=10Additionally, each of these y-values increases by 5. So, once we found the first y-value, 0, we can just add 5 to find the next y-values.
Graphing
Also, you can use a graph to find the missing values. The y-intercept is 0 and the slope is 5. Using this information you can graph the equation. Then, find the x-values on the graph and match these values to y-values.

the dimensions of rectangle ABCD are shown below. (picture included)
A) 4.5
B) 7.5
C) 13.5
D) 19.5
Answer:
I believe the answer is 13.5
Step-by-step explanation:
because u need to find the area of a triangle which is Area= b*h*0.5 so fill in the blank b=9 h=3 b*3*0.5=13.5
Answer:
D). 19.5
Step by step answer:
Bigger triangle:
4 + 5 = 9 (Base)
Height = 3
A = 9 x 3 / 2 = 13.5
Smaller triangle:
Height = 3
Base = 4
A = 4 x 3 / 2 = 6
6 + 13.5 = 19.5
