Answer:

A- Students who do not act

B- Every 4th student selected from an alphabetical register of the club

E- Students whose names are randomly selected from a hat

Step-by-step explanation:

A drama teacher wants to decide where the drama club should go to celebrate their performance.

We are to determine whether which of the options is not a representative sample.

By definition, a sample which is the subset of the bigger population reflecting the characteristics is said to be a representative sample.

So the correct options are:

A- Students who do not act

B- Every 4th student selected from an alphabetical register of the club

E- Students whose names are randomly selected from a hat

Answer:

Step-by-step explanation:

The objective is to determine where the drama club should go to celebrate their final performance.

In orther to achieve that objective, the sample must be representative. For example, the sample must be formed by students that actually acts.

Therefore, A, B and E are not representative samples because they don't act, every 4th student selected doesn't imply that all of them act, and selecting randomly names won't represents students that actually acts.

The total surface area of a square pyramid with a side length of 4 feet and a height of 6 feet is 64 square feet.

To find the total surface area of a square pyramid, we need to calculate the area of the base and the area of all four triangular faces. The area of the base (a square) can be found using the formula side². In this case, that's 4² which equals 16 square feet. To find the area of a triangular face, we use the formula 0.5 * base * height. Since we have 4 identical triangular faces, we calculate this once and then multiply by 4. The base of each triangle is the side of the square, which is 4 feet, and the height is given as 6 feet. Plugging these values into the formula we get 0.5 * 4 * 6 = 12 square feet for one triangular face. Since there are 4 of these faces, the total surface area of the faces is 4 * 12 = 48 square feet. Adding this to the area of the base, we find the total surface area of the pyramid is 16 + 48 = 64 square feet.

To find the total area of a square pyramid, calculate the area of the base and the area of the four triangular faces. The total area is 64 square feet.

To find the total area of a square pyramid, you need to calculate the area of the base and the area of the four triangular faces. Since the base is a square with sides measuring 4 feet, its area is 4 x 4 = 16 square feet.

To find the area of each triangular face, you can use the formula for the area of a triangle: (base x height) / 2.

In this case, the base of each triangular face is 4 feet and the height is 6 feet, so the area of each face is (4 x 6) / 2 = 12 square feet. Since there are 4 triangular faces, the total area of these faces is 4 x 12 = 48 square feet.

Finally, you can find the total area of the pyramid by adding the area of the base and the area of the faces: 16 + 48 = 64 square feet.

Therefore, the total area of the square pyramid is 64 square feet.

It is unknow. This is because x can be any number.

Answer: [tex]x=-8\\y=0[/tex]

Step-by-step explanation:

You can apply the elimination method:

- Multiply the first equation by -2.

- Add both equations to cancel out the variable x.

- Solve for y:

[tex]\left \{ {{(-2)(x-4y)=-8(-2)} \atop {2x-3y=-16}} \right.\\\\\\\left \{ {{-2x+8y=16} \atop {2x-3y=-16}} \right.\\ ------\\5y=0\\y=0[/tex]

- Substitute y=0 into any of the original equations ans solve for x. Then:

[tex]x-4(0)=-8\\x=-8[/tex]

The answers are:

[tex]x=-8\\y=0[/tex]

Since we have to equations, first we need to isolate one variable, and then substitute it into the other equation.

So, isolating x from the first equation we have:

[tex]x-4y=-8\\x=-8+4y[/tex]

Then, substituting "x" into the second equation, we have:

[tex]2(-8+4y)-3y=-16\\-16+8y-3y-=-16\\5y=-16+16\\5y=0\\y=\frac{0}{5}=0[/tex]

Therefore, substituting "y" into the first equation, we have:

[tex]x-4(0)=-8\\x-0=-8\\x=-8[/tex]

So, the solutions for the system of equation are:

[tex]x=-8\\y=0[/tex]

Step-by-step explanation:

We graph the function.

Final answer:

Plotting points that satisfy an equation or inequality creates a graph representing their relationship, with lines or curves like parabolas depending on the equation type.

Explanation:

When we plot all the points that satisfy an equation or inequality, we create a visual representation of the relationship between variables that are described by that equation or inequality. For instance, if the equation is linear and we plot its solutions on a graph, we will see a line. The y-intercept is an important feature of this line, indicating the point where the plot crosses the y-axis. In the case of a quadratic equation, plotting its solutions results in a parabola. If we want to determine whether the plot crosses a particular axis, such as the t-axis, we may need to analyze the discriminant (D) of the quadratic equation, which tells us whether the equation has real roots and, consequently, intersects with the axis.

9x= 4x +35

5x=35

x=6

ask if u need explanation

To find the value of x that makes the equation true, you need to solve the equation 9x = 4x + 25 by subtracting 4x from both sides and then dividing by 5 to find x = 5.

Value of x: To find which value of x makes the equation 9x = 4x + 25 true, you need to solve the equation.

Step-by-step explanation:

Subtract 4x from both sides: 9x - 4x = 25

This simplifies to 5x = 25

Divide by 5 to solve for x: x = 5

Therefore, the value 5 makes the sentence 9x= 4x+ 25​ true.

The total number of paper airplanes Fiona and her family made can be represented by the numerical expression: (12 + 8) x 2 + 3.

The total number of paper airplanes Fiona and her family made can be represented by the numerical expression: (12 + 8) x 2 + 3. The expression uses parentheses to indicate that the addition of 12 and 8 should be done first. Then, the result is multiplied by 2 to account for the doubling of planes in the afternoon. Finally, 3 is added to account for the extra planes made by Fiona's little brother. This expression represents the total number of paper airplanes made by Fiona and her family without simplifying it.

The given points have the same Y value.

Find the distance between the X values -3 to 1 is 4 units.

All sides of a square are the same length so the other points must be 4 units away.

Add 4 units to the Y values:

Answer:

750 sq. ft

Step-by-step explanation:

To understand the area of a triangle, we can start with the area of a rectangle. The area of a rectangle with some length (which I'll call L) and some width (which I'll call W) is just the product of those two values, L × W. How does this carry to triangles? Well we can take any triangle we want and draw a rectangle around it, using the base of the triangle as one of the rectangle's sides.

Now, the key here is to cut that original rectangle into two smaller ones, starting at the top point of the triangle. Notice now that half of the left rectangle is taken up by the orange triangle, and half of the right one as well. Putting those two together, we can say that the big orange triangle takes up exactly half of the green rectangle, or in other words, its area is (L × W) ÷ 2. Of course, when we talk about triangles, we use the words "base" (B) and "height" (H) rather than length and width, so you could also say that the area of a triangle is (B × H) ÷ 2.

Taking this into our problem, we're given a base of 100 ft and a height of 15 feet; using our newly-discovered equation, we find its area to be

(100 × 15) ÷ 2 = 1500 ÷ 2 = 750 sq. ft.

Applying the angle bisector theorem, the value of x is: B. 5.3.

An angle bisector divides an angle into two congruent halves. According to the angle bisector theorem, an angle bisector of a triangle divides the interior angles opposite sides in such a way that the corresponding lengths are proportional to each other. This means that the corresponding sides have ratios that are equal.

In the image given, applying the angle bisector theorem, we have the following proportion which we can use to find the value of x in the triangle given above:

6/x = 9/8 [according to the angle bisector theorem]

Cross multiply

(9)(x) = (6)(8)

9x = 48

Divide both sides by 9

9x/9 = 48/9

x = 5.333

Thus, to the nearest tenth, the value of x is approximately calculated as: B. 5.3
