It depends on the length of the festival, the length of each band's performance, and other factors. There could be any number of ways to schedule their appearances.
The number of ways to schedule the bands' appearances at the weekend festival depends on a variety of factors such as the length of the festival, the length of each individual band's performance, and the number and type of stages available.
For example, if the festival runs for two days and each band's performance is one hour, there could be a total of 22 hours of music, so eleven bands could each perform twice, once on each day.
Alternatively, if the festival has three stages and two of the stages are dedicated to different genres of music, then the bands could be scheduled to perform on those stages, with each stage hosting five bands each day.

To find the probability that the student ONLY takes History Class, we need to divide the number of students taking only History (37) by the total number of students (150).
What is probability?Probability is the measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. Probability can be used to analyze and make predictions about a wide range of situations, including games of chance, weather patterns, financial markets, and more.
Here,
Using the given numbers, we can calculate the probabilities as follows:
To find the probability that the student ONLY takes History Class, we need to divide the number of students taking only History (37) by the total number of students (150):
P(ONLY History) = 37/150 = 0.2467 or approximately 24.67%
To find the probability that the student takes BOTH History and Biology, we need to divide the number of students taking both (25) by the total number of students (150):
P(History AND Biology) = 25/150 = 0.1667 or approximately 16.67%
To find the probability that the student does NOT take History or Biology, we need to add the number of students taking neither History nor Biology (21) to the number of students taking only Biology (17), and then divide by the total number of students:
P(Neither History nor Biology) = (21 + 17)/150 = 0.2533 or approximately 25.33%
The complement of this event (i.e., the probability of taking either History or Biology) is:
P(History or Biology) = 1 - P(Neither History nor Biology) = 1 - 0.2533 = 0.7467 or approximately 74.67%
To find the probability that the student takes Biology class, we need to add the number of students taking both History and Biology (25) to the number of students taking only Biology (17), and then divide by the total number of students:
P(Biology) = (25 + 17)/150 = 0.2133 or approximately 21.33%

What are x and y i don't know
Answer:
Step-by-step explanation:
Perimeter of the rectangle= 42 cm
Length= x
Breadth= y
2(x+y)= 42
x+y= 42/2= 21 (Let it be the first equation)
Perimeter of the triangle= 36 cm
x+y+2y-3= 36 cm (Let it be the second equation)
Substitute equation 1 in 2.
x+y+2y-3= 36
⇒ 21+2y-3= 36
2y= 36-21+3
2y= 18
y= 18/2
y= 9
x+y= 21
x+9= 21
x= 21-9
x= 12
∴ the values of x and y are 12 and 9 respectively.
Which graph represents the solutions to this equation?
x2 + 8x = -20
A, B, C, or D?
(See pictures attached)
Answer:
Step-by-step explanation:
The answer is Graph B.
First the equation needs to be in standard form.
x² + 8x= -20
becomes y = x² + 8x + 20
The leading coefficient is positive - a positve one is in front of the x.
So the parabola opens upward.
solve for the x coordinate of the minimun by using the formula
x = -b/2a
x = -8/2(1) = - 8/2 = -4
substitute -4 into the original equation.
y = (-4)² + 8(-4) + 20
y = 16 + -32 + 20
y = -16 + 20
y = 4
so the minimun - or bottom of the parabola is (-4, 4)
Correct choice is graph B

What is the exponential function?
An exponential function is a Mathematical function in form f (x) = ax, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0. The most commonly used exponential function base is the transcendental number e, which is approximately equal to 2.71828.
The exponential function can be described as y = 3 * 2ˣ,
where,
x is the input value
and y is the output value.
This function says that for every increase in x by 1 unit, the value of y will be multiplied by 2, starting from an initial value of 3.
For example, when x = 0, y = 3 * 2⁰ = 3, and when x = 1, y = 3 * 2¹ = 12.
Hence, the exponential function for each set of points is y = 3 * 2ˣ,

Emma wrote the expression 2(3w-6) to represent the amount of money that Juan spent. Is she correct? Explain
Yes, Emma is correct. The expression 2(3w-6) represents two times the difference of three times w and six. w can represent any amount of money, so this expression represents twice the amount of money that Juan spent.
2(3w-6) = 6w - 12
2(3w-6)
2 • (3w - 6)
2 • 3w - 2 • 6
6w - 12
The expression 2(3w-6) can be expanded by first multiplying the two together. This is done by multiplying the coefficient of 2 with each of the terms inside the parentheses. This results in 2 • 3w - 2 • 6. Next, the terms inside the parentheses can be combined. Since they are both being multiplied by 2, we can simply add the two terms together, resulting in 6w - 12. Thus, the expression 2(3w-6) can be expanded to 6w - 12.The expression 2(3w-6) represents two times the difference of three times w and six. w can represent any amount of money, so this expression represents twice the amount of money that Juan spent.

I want to build a rectangular garden so that the length is 45 meters more than twice the width. I have 1350 meters of fencing available. What dimensions should I make the garden?
Answer:
Step-by-step explanation:
Let's start by defining the variables for the problem. Let's say that:
w = the width of the rectangular garden (in meters)
l = the length of the rectangular garden (in meters)
We know that the length is 45 meters more than twice the width, so we can write:
l = 2w + 45
We also know that we have 1350 meters of fencing available to enclose the rectangular garden. The perimeter of the rectangular garden is equal to the sum of the lengths of all four sides. Since there are two sides of length w and two sides of length l, we can write:
Perimeter = 2w + 2l
Substituting the expression for l that we derived earlier, we get:
Perimeter = 2w + 2(2w + 45)
Perimeter = 6w + 90
We know that the perimeter of the rectangular garden is equal to 1350 meters, so we can write:
1350 = 6w + 90
Solving for w, we get:
6w = 1260
w = 210
Now that we know the value of w, we can use the expression for l that we derived earlier to find the length:
l = 2w + 45
l = 2(210) + 45
l = 465
Therefore, the dimensions of the rectangular garden should be 210 meters by 465 meters.
Find an equation for the line that passes through the points (-2, 1) and (4, 3)
Answer: y=x/3 + 5/3
Step-by-step explanation:
Answer:
Step-by-step explanation:
To find the equation of the line that passes through the points (-2, 1) and (4, 3), we can use the point-slope form of a line.
Point-slope form of a line: y - y1 = m(x - x1), where m is the slope of the line and (x1, y1) is a point on the line.
Step 1: Find the slope:
We can use the two points to find the slope:
m = (y2 - y1) / (x2 - x1) = (3 - 1) / (4 - (-2)) = 2
Step 2: Use the point-slope form:
y - 1 = 2(x - (-2))
y - 1 = 2x + 4
y = 2x + 5
The equation of the line that passes through the points (-2, 1) and (4, 3) is y = 2x + 5. This is the standard form of the line.

Juan wants to buy a guitar. The regular price of the guitar is $329.99. The sales price of the guitar is 25% off of the regular price. Juan most Pat 7.25% sales tax in addition to the sales price of the guitar. What is the total amount Juan must pay for the guitar?
The supplied document states that Juan must pay $265.32 in total for the instrument.
By sales, what do you mean?Any transaction in which goods or services are exchanged for cash is referred to as a sale. In other words, a transaction is any activity that involves transferring ownership of a good or service to the buyer in exchange for cash.
The instrument costs $329.99 at standard pricing.
$329 * 25% = $82.50
The guitar's discount price is thus $329.99 less $82.50, or $247.49.
7.25% of the purchase price is used to compute sales tax.
Therefore, $247.49 * 7.25% = $17.83
As a result, we eventually tack on the taxation to the purchase price to determine Juan's final obligation to pay for the guitar.
$247.49 + $17.83 = $265.32
The total price that Juan shall pay for something like the guitar is thus $265.32.

Suppose EL=24, DM = 12, and FM = 6.
Find the following lengths.
Note that the figure is not drawn to scale.
Answer:
DK = 18
MJ = 3
ML = 8
Step-by-step explanation:
In this problem, we need to use the Median of a Triangle Formula. This formula states that EM/EL = FM/JF = DM/DK = 2/3. To implement this into our question, we can write ML/EL = 1/3, so we get that ML = 24/3 = 8. We also know that MJ/FM = 1/2, so MJ = 6/2 = 3. Finally, DM/DK = 2/3, so DK = (12*3)/2 = 18. Hope this is correct.
Which model shows and angle that appears to represent 45/360 of a circle
A protractor is a tool used for measuring and drawing angles. It is typically a semi-circular piece of plastic or metal with a degree scale marked along its curved edge.
The scale typically ranges from 0 to 180 degrees, which covers half a circle. To measure or draw an angle of 45 degrees, you would line up the protractor's baseline with one arm of the angle and use the degree scale to find 45 degrees. If you are drawing the angle, you would then use a straightedge to extend the other arm of the angle from the point where it intersects the 45-degree mark on the protractor.
It's important to note that the 45-degree angle represents 45/360 of a full circle, which is equal to one-eighth of a full rotation. This means that if you were to rotate the angle around its vertex, it would make one-eighth of a full circle before aligning with its original position.
