The correct option is,

⇒ get a list of students at her school from the office and use a random number generator to pick 30 of them.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Bella want to know what the students at her school think of her show. which is the BEST group to survey to find this information

Now, For getting accurate results she must select a random sample without bias

For this option a will not serve since she selects only students she recognizes.

Hence, Option B may not be right, as during show on the face they may not give correct opinion

And, Option C is right as a random sample is taken

And, Option D is wrong as the first 30 students may not be at random.

Thus, The correct option is,

⇒ get a list of students at her school from the office and use a random number generator to pick 30 of them.

Answer:

A

Step-by-step explanation:

A proportional relationship either increases or decreases its points at the same rate. In the first set of ordered pairs, the x values all increase by 3 while the y values all increase by 6, which is twice the value of the x values' increasing. The second set of ordered pairs is not proportional because all pairs' x values increase by 2 while the y values increase by 8 until ordered pair (5, 20), so this set therefore is non-proportional. y = x + 3 is the correct equation because it represents that the y value is always 3 greater than the x value. All the shown ordered pairs for set 1 supports this (3 - 0 = 3, 6 - 3 = 3, 9 - 6 = 3, 12 - 9 = 3).

Answer:

Answer is in attachment. I am really sorry if I'm wrong.

Step-by-step explanation:

Greatest common factor (GCF) is the highest number that is a factor of 2 numbers. Not sure if that makes sense.

For example, GCF of 8 and 4 is 4, because 4 is the highest factor that fits into both numbers. 4x2=8 and 4x1=4.

In this case, the height is 7, because that's the GCF of 21 and 70. There's no bigger common factor than that. 7x3=21 and 7x10=70

Now that we know the "height", even though there's no such thing as height when calculating the area, we know the length.

The area of something is length x width. Your assignment calls it height for some reason so we'll use height x length.

Area of the 2 shapes is already given, which is 21n for the first shape. Length of the first shape is 3n because 3nx7=21n. Recall that 7 is what we found earlier.

As we can see, the "height" of the 2nd shape is the same as the first, therefore it should also be 7.

Since we are given the area of the 2nd shape, we now know its length. Length of 2nd shape is 10, because 7x10=70.

Step-by-step explanation:

K is Center, Radius KJ KI,KI, JR diameter.

Here we have given a diagram from the given diagram

Center :- The center of a circle is the point equidistant from the points on the edge

Therefore center is k.

Radius:-The distance from the center of the circle to any point on it's circumference

Radius is KJ,KL,KI

Chord :-The chord of a circle can be defined as the line segment joining any two points on the circumference of the circle.

chord is J and I

Diameter:-In a circle, diameter is a line that passes through the center and meets the circumference at opposite ends.

JR is the diameter.

Answer:

WT = 34

Step-by-step explanation:

The ultimate goal here to pinpoint what x is equivalent to. In a rectangle we know that the diagonals are congruent as well as the fact that they bisect each other. This means cutting in half. Using this knowledge we know VW = 9x - 11 is half of SU = 16x - 12.

Step One: Multiply 9x - 11 by 2.

2(9x - 11) = 18x - 22

Step Two: Set up your equation

18x - 22 = 16x - 12

Step Three: Solve for x

18x - 22 = 16x - 12

2x - 22 = -12

2x = 10

x = 5

Step Four: Substitute to check your work

16(5) - 12 = 68

9(5) - 11 = 34

Again, since the diagonals of a rectangle bisect each other VW = WT.

34 is half of 68 proving our findings.

The length of WT is 34.

Rectangle is a two dimensional figure which has four sides and four angles and all the angles are right angles.

We have,

VW = 9x - 11

Diagonals of a rectangle bisect each other.

So, WT = 9x - 11

VT = 2(9x - 11)

Also, we have,

SU = 16x - 12

The two diagonals of a rectangle are equal.

2(9x - 11) = 16x - 12

18x - 22 = 16x - 12

18x - 16x = -12 + 22

2x = 10

x = 5

WT = 9x - 11 = (9 × 5) - 11 = 34

Hence the length of the line WT is 34.

The weight of an object is how heavy the object is

The capacity of a container is the amount the container can hold.

A standard coffee mug has a capacity of 16 fluid ounces. If Annie needs to fill 26 mugs with coffee, how many total quarts of coffee does she need?

Annie needs 13 quarts of coffee. I know this because 1 US quart is 32 US fluid ounces. 16 fluid ounces multiplied by 26 mugs of coffee is 416 and then you convert 416 fluid ounces into 13 quarts.

Convert: 9 T =  18,000 lb

Answer:

4,200

Step-by-step explanation:

Tenemos un total de:

4 libros de matemáticas

3 libros de biología

3 libros de religión

10 libros en total.

Ahora vamos a contar la cantidad de opciones que tenemos para cada posicion.

Primer libro (tenemos 10 opciones)

segundo libro (tenemos 9 opciones, porque ya colocamos un libro)

tercer libro (tenemos 8 opciones, porque ya colocamos dos libros)

Con esto ya podemos estimar el número de opciones para cada posicion, y sabemos que el número total de combinaciones es igual al producto entre los números de opciones para cada caso. El número total de combinaciones es:

C = 10*9*8*7*6*5*4*3*2*1 = 10!

Ahora si asumimos que no podemos diferenciar los libros de matemáticas, entonces no debemos contar sus permutaciones (si tenemos 4 libros de matemáticas, tenemos 4*3*2*1 permutaciones = 4! permutaciones). Debemos dividir al numero total de combinaciones por 4!.

Y lo mismo pasa para las 3! permutaciones de los libros de biología y las 3! permutaciones de los libros de religión.

Entonces el número total de combinaciones diferentes es:

[tex]C = \frac{10!}{3!*4!*3!} = \frac{10*9*8*7*6*5*4*3*2*1}{(3*2*1)*(4*3*2*1)*(3*2*1)} = 4,200[/tex]

Answer:

She made eight 2 pointers

She made four  3 pointers

Step-by-step explanation:

2x + 3y = 28

x + y    = 12                 Multiply this equation by 2

2x + 2y =24

Write the first and third equations underneath each other,

2x + 3y = 28

2x + 2y = 24              Subtract.

        y = 4

x + y = 12

x + 4 = 12                     Subtract  4 from each side
