we will flip a balanced coin 3 times and for each toss, record whether we get a head or a tail. write all possible outcomes of this experiment to find the probability that we get exactly 0 tails.
Answers
The probability of getting exactly 0 tails is 1/8 or 0.125.
The coin flip experiment involves three independent events, each representing the outcome of one coin flip. Since each coin flip is balanced, the outcome of each event can either be heads (H) or tails (T). Therefore, for each event, there are two possible outcomes.
Since each event is independent, the number of possible outcomes of three events is equal to the product of the number of possible outcomes of each individual event. This means that the number of possible outcomes of three coin flips is equal to 2 * 2 * 2 = 8. The possible outcomes of three coin flips can be listed as follows:
HHH
HHT
HTH
THH
THT
TTH

Out of these eight possible outcomes, only one outcome (HHH) results in getting exactly 0 tails. So the probability of getting exactly 0 tails is 1/8 or 0.125.

HELP NOW Cynthia Besch wants to buy a rug for a room that is 18 ft wide and 26 ft long. She wants to leave a uniform strip of floor around the rug. She can afford to buy 180 square feet of carpeting. What dimensions should the rug have? The dimensions of the rug should be 28 ft. (Use a comma to separate answers as needed)
Answers
Answer: To find the dimensions of the rug, we need to subtract the width of the floor strip from both the length and the width of the room. Let x be the width of the floor strip in feet. Then the dimensions of the rug will be 18-2x by 26-2x.
The area of the rug is given by:
(18-2x)(26-2x) = 180
Expanding the right-hand side gives:
468 - 72x + 4x^2 = 180
Rearranging the equation gives:
4x^2 - 72x + 288 = 0
We can use the quadratic formula to find the solutions for x:
x = (-b ± √(b^2-4ac)) / 2a
where a = 4, b = -72, and c = 288
x = (72 ± √(72^2 - 4(4)(288))) / 2(4)
x = (72 ± √(72^2 - 4(1152))) / 8
x = (72 ± √(72^2 - 4608)) / 8
x = (72 ± √(5184)) / 8
x = (72 ± 72) / 8
x = (144 ± 72) / 8
x = 72 / 8 or 0
Since the width of the floor strip cannot be negative, x = 9 feet. So, the dimensions of the rug should be 18 - 2 * 9 = 0 ft by 26 - 2 * 9 = 8 ft.
Step-by-step explanation:
The values of x are 18 and 4
How to solve for the values of xWe have the area of a rectangle
A = L* B
The l and the b would get increased by 2x
180 = (18 - 2x) (26 - 2x)
We have to open the bracket
468 - 36x - 52x + 4x² = 180
468 - 180 - 88x + 4x² = 0
rearrange the equation
4x² - 88x + 288 = 0
Solve using the quadratic formula equation
This would give us x = 144 / 8 and 32 / 8
x = 18 and x = 4

Elena and Jada were racing on their bikes. Elena started 15 meters ahead of Jada. Elena biked at a rate of 20 meters per second. Jada biked at a rate of 22 meters per second. Let x represent time in seconds and y represent distance in meters. Write a system of equations to represent the situation
Answers
If x represents time in seconds and y represents distance in meters then the system of equations to represent the above situation are
20x - y = 0 and 22x - y = 15
Let x represent time in seconds and y represents distance in meters.
Let u be the speed of Elena and v be the speed of Jada.
So, according to question,
u = 20[tex]ms^{-1}[/tex] and v = 22[tex]ms^{-1}[/tex]
We know, Speed = [tex]\frac{Distance}{Time}[/tex]
So, 20 = [tex]\frac{y}{x}[/tex]
which implies 20x = y
20x - y = 0 ......................(1)
Similarly,
22 = [tex]\frac{y + 15}{x}[/tex]
Which implies 22x = y + 15
22x - 15 = y.....................(2)
Substituting the value of y from equation (2) in (1)
20x - (22x - 15) = 0
20x - 22x + 15 = 0
15 - 2x = 0
2x = 15
x = 7.5
Substituting the value of x in equation (1)
20 x - y = 0
20 × 7.5 = y
y = 150
The values of x and y satisfies the stated conditions,
Hence, the system of equations to represent the above situation are
20x - y = 0 and 22x - y = 15

--> cost to get started
The change in total cost:
--> essentially, the slope value that is given in the equation:
[tex]y=25x+1150[/tex]
--> thus, the change in total cost per book is $25
The cost to get started before printing any books:
--> we can essentially set 'x' equal to 0 to signify no books being printed
yet
[tex]y=25x+1150=25(0)+1150=1150[/tex]
--> the total cost before printing any books is $1150
Answer:
change in total cost for each book printed: $25total cost before printing any book: $1150Answer:
1. The change in total cost for each book printed is $25
2. The cost to get started is $1,150
Step-by-step explanation:

-Y/-1 = -25x/-1 - 1150/-1
Y = 25x + 1150
To get the total cost to get started let X = 0
Y = 25x + 1150
Y = 25(0) + 1150

1. Suppose a graph passes the horizontal line test: No horizontal line can be drawn that touches the graph in more than one location. Does this mean that the graph represents a function? If not, is there anything special about a graph that passes the horizontal line test? Share your ideas with a classmate.
2. Dotty and Lionel are making a graph comparing a car's age with its gas mileage. Dotty says the graph should show discrete points because the car's age is stated in whole numbers of years. Lionel says they should make a continuous line because age increases gradually, like time. Which student do you agree with and why?
3. Write two linear functions, f(x) and g(x). For example, f(x) = 3x - 7 and g(x) = -2x + 5. Then see whether f(x) - (-g(x)) is equivalent to f(x)+ g(x). Hint: To find -g(x), just change the signs of all the terms in g(x). Discuss whether you think your results would apply to every function..
Answers
A graph that passes the horizontal line test represents a function. This is because if a horizontal line can only intersect the graph at one point, it means that each input value (x) has a unique output value (y), which is the definition of a function. This is true.
How to explain the informationI agree with Lionel, the graph should show a continuous line because age increases gradually like time. Also, age is usually not a discrete variable, it's a continuous variable that can have fractional values, so a line graph is more appropriate to represent the relationship between age and gas mileage.
Let's take f(x) = 3x - 7 and g(x) = -2x + 5 as two linear functions.
f(x) - (-g(x)) = 3x - 7 - (-2x + 5) = 3x - 7 + 2x - 5 = 5x - 12
f(x) + g(x) = 3x - 7 + (-2x + 5) = x - 2
So f(x) - (-g(x)) is not equivalent to f(x) + g(x). This result would not apply to every function, as the properties of addition and subtraction of functions depend on the specific functions being used.

At a local theater, 2/3 of the seats are located on the main floor. The remaining seats are located in the balcony. There are 600 seats on the main floor.
How many total seats are in the theater?
For an upcoming show, 4/5 of the floor seats have been sold and 1/2 of the balcony seats have been sold. What overall fraction of the seats in the whole theater have been sold?
Answers
Overall fraction of sold seats is 0.63333...
How to find the total number of seats in the theaterFirst we use the fact that 2/3 of the seats are located on the main floor and the number of seats on the main floor is 600, so the total number of seats can be calculated as follows:
Total number of seats = 600 / (2/3) = 900 seats
Next, we can find the number of seats in the balcony:
Balcony seats = Total number of seats - Main floor seats = 900 - 600 = 300 seats
Next, we can find the number of sold floor seats:
Sold floor seats = 4/5 * 600 = 480 seats
And the number of sold balcony seats:
Sold balcony seats = 1/2 * 300 = 150 seats
Finally, to find the overall fraction of sold seats in the theater, we add the number of sold floor seats and the number of sold balcony seats and divide by the total number of seats:
Overall fraction of sold seats = (480 + 150) / 900 = 0.63333... (rounded to the nearest hundredth)

The measures angles are 70° and 52°
Similar triangles:The triangle in which the ratio of corresponding is equal and has an equal measure of angles is known as Similar triangle.
If ABC and XYZ are two similar triangles, the corresponding angles must be equal
=> ∠A = ∠X, ∠ B = ∠Y, ∠C = ∠Z
Here we have
ΔDEF and ΔJKL are similar triangles
As we know angles of similar triangles are equal
=> ∠D = ∠J = (9x - 20)°
=> ∠E = ∠K = 52°
=> ∠F = ∠L = (7x - 12)°
As we know the sum of angles in triangles = 180°
=> ∠D + ∠E + ∠F = 180°
=> 9x - 20° + 52° + 7x - 12° = 180°
=> 16x + 20° = 180°
=> 16x = 160°
=> x = 160°/16
=> x = 10°
At x = 10° measures of angles are
=> (9x - 20)° = 9(10) - 20° = 70°
=> (7x - 12)° = 7(10) - 12° = 58°

Answers
The volume of water in the well is 6 x 4 x 10 = 240 ft3. Since water is running into the well at the rate of 3 ft3 per minute, the water is rising at the rate of 3/240 ft per minute or 1/80 ft per minute.
The volume of water in the well is 6 x 4 x 10 = 240 ft3. Since water is running into the well at the rate of 3 ft3 per minute, the water is rising at the rate of 3/240 ft per minute or 1/80 ft per minute.
To calculate this, we can use the following formula:
Rate of Water Rising = Volume of Water Added Per Minute / Total Volume of Well
Rate of Water Rising = 3 ft3/min / 240 ft3
Rate of Water Rising = 1/80 ft per minute
Therefore, The volume of water in the well is 6 x 4 x 10 = 240 ft3. Since water is running into the well at the rate of 3 ft3 per minute, the water is rising at the rate of 3/240 ft per minute or 1/80 ft per minute.

let the continuous random variable x denote the current measured in a thin copper wire in milliamperes. assume that the range of x is [0, 20 ma], and assume that the probability density function of x is f (x) 0.05 for 0 x 20. what is the probability that a current measurement is less than 10 milliamperes?
Answers
The probability that a current measurement is less than 10 milliamperes can be found by computing the cumulative distribution function (CDF) of the random variable x at 10 milliamperes.
The CDF of a continuous random variable x is defined as the probability that x is less than or equal to a given value.
In this case, we want to find the CDF of x at 10 milliamperes, which we can write as F(10), where:
F(10) = P(X <= 10) = ∫_0¹⁰ f(x) dx
Using the probability density function f(x) given in the problem, we can evaluate the integral to find the CDF:
F(10) = ∫_0¹⁰ 0.05 dx = 0.5
So the probability that a current measurement is less than 10 milliamperes is 0.5. This means that half of the possible current measurements will be less than 10 milliamperes, and half will be greater than 10 milliamperes.

The point T( – 1,2) is rotated 180° clockwise around the origin. What are the coordinates of the resulting point, T'?
Answers
The coordinates of the resulting point, T' after the point T( – 1,2) is rotated 180° clockwise around the origin is (1, -2).
To rotate a point 180° clockwise around the origin, you can apply the following transformations:
Reflect the point across the x-axis by negating its y-coordinate.
Reflect the point across the y-axis by negating its x-coordinate.
Starting with T( – 1,2), we first reflect the point across the x-axis, which gives us T'( – 1, -2). Then, we reflect T' across the y-axis, which results in T''(1, -2).
The transformation can be represented as follows:
T' = (x, -y)
T'' = (-x, -y)
Therefore, the final coordinates of T'' are (1, -2).
