The option (D) the range is 70 and the midrange is 35 is correct option (D) would be correct.

It is defined as the difference between the maximum value in the data set to the minimum value in the data set.

The range is a quick yet effective technique to understand the distribution of the numbers in the data collection. Furthermore, since it simply calls for a simple arithmetic operation, it is simple to calculate. The standard deviation, a different measure of spread, can also be estimated using the range.

Range = max value - min value

Range = 85 - 15

Range = 70

Mid range = 70/2 = 35

Thus, the option (D) the range is 70 and the midrange is 35 is correct option (D) would be correct.

Without specific statements to evaluate, we can't determine which is true for the set of numbers given. These numbers could represent heights in inches, and more context is needed to provide an accurate answer.

The student may be asking which statement regarding the listed set of numbers is true. These numbers are 20, 15, 50, 85, 75, 60. Without knowing the specific statements, we cannot definitively say which one is true or false. However, we can examine the statistics provided for a different data set of students' heights and base our answer on typical statistical questions.

A true statement about this set could be related to trends, averages, medians, modes, ranges, or any other statistical measure. For example, if asked whether this set of numbers could represent a set of heights, the answer could be true, assuming these numbers are in inches since all fall within a plausible range of human heights.

More context or specific questions about the data set would be needed for a more precise answer. The reference information about the heights of students, percentile data, and uniform distributions provide examples of typical problems in a statistics class.

Answer:

V = 490 cm^3

Step-by-step explanation:

V = l*w*h

V = 7*10*7

V = 490 cm^3

To find the volume of a rectangular prism, we use the formula

Volume = length × width × height.

Since the rectangular prism has a length of 10 cm, a width of 7 cm, and a height of 7 cm we can plug this information into the formula.

(10 cm) (7 cm) (7 cm)

10 × 7 = 70

70 × 7 = 490 cm³

Answer:

Step-by-step explanation:

The slope-intercept form of an equation of a line:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

==============================================

From the table we have :

x = 1 → y = 6

x = 2 → y = 9

x = 3 → y = 12

x = 4 → y = 15

Calculate the slope (choice any two pairs, and calculate the slope):

(1, 6), (2, 9)

[tex]m=\dfrac{9-6}{2-1}=\dfrac{3}{1}=3[/tex]

We have the equation:

[tex]y=3x+b[/tex]

Put the coordinates of the point (1, 6) to the equation, and solve it for b:

[tex]6=3(1)+b[/tex]

[tex]6=3+b[/tex]              subtract 3 from both sides

[tex]3=b\to b=3[/tex]

Finally:

[tex]y=3x+3[/tex]

Answer:

Yes The triangles are similar by SAS Similarity Theorem

Step-by-step explanation:

we know that

Side-Angle-Side Similarity, states that If an angle of a triangle is congruent to an angle of another triangle and if the included sides of these angles are proportional, then the two triangles are similar

In this problem

Angle  L is congruent with Angle Z

so

Verify if the included sides are proportional

so

[tex]\frac{LJ}{ZY}=\frac{KL}{XZ}[/tex]

substitute the values

[tex]\frac{3}{1.5}=\frac{4}{2}[/tex]

[tex]2=2[/tex] -----> is true

therefore

The triangles are similar by SAS

Area = r^2 x PI

to find r take the square root of the area:

r = √100 = 10

The circumference of a circle is the diameter times PI.

The diameter is 2 times r = 2 x 10 = 20

The circumference = 20PI m

The answer is C.

Answer:

6(7 - 3y) + 6(y + 1) = 42 - 18y + 6y + 6 =

-12y + 48 = 12(4 - y)

The expression 6(7-3y)+6(y+1) simplifies to 48-12y by distributing the 6 and combining like terms.

To simplify the expression 6(7-3y)+6(y+1), we need to apply the distributive property and then combine like terms.

The simplified equivalent expression is 48 - 12y.

To check that the expression is reasonable, you can substitute values for y and see if the original and the simplified expressions yield the same result.

Thus, for the given equation, the result is obtained as: 48 - 12y.

-3 because below is less and 3 less than zero is -3

6 because sea level would be zero and 6 above is 6

-5 cause your losing 5 pounds which means its 5 less so -5

4 because say you have zero dollars then you find 4 you now have positive 4

The answer to this is A and E, W and X, C and P

A is -7

E is 7

These are opposite

W is -5

X is 5

These are opposite

B is -3

C is 3

These are opposite

The answer is A

Answer:

A. A and E, W and X, C and P

Step-by-step explanation:

The opposite of any number (let's call it "x") is a number which, if added to x, results in 0.

Typically is -x, because x + (-x) = x - x = 0

Knowing these, let's see the values that are marked:

A = -7

W = -5

C = -3

B = 1

P = 3

X = 5  

E = 7

The opposite of 7 is -7, so A and E are opposites.

The oposite of 5 is -5, so X and W are opposites

The opposite of 3 is -3, so P and C are opposites.

The opposite of 1 is -1, but -1 is not marked.

The correct answer is the first one.

The new coordinations would be (6,8)

Answer:

(6, 8)

Step-by-step explanation:

The y- axis (the vertical axis) acts as a mirror point.  When reflecting over the y axis, the y value will stay the same.  Think about looking into a mirror on your wall, your height is the same on both sides of the vertical reflecting object

The x-value will change and be the other side of the y-axis.  It will be the same distance away from the y-axis that is was, but will have an opposite sign.

Here is was 6 units to the left of the y-axis (where x values are negative), now it is 6 units to the right of the y-axis (where x values are positive)

Answer:

x + 2

Step-by-step explanation:

3x^3 - 12x

=3x(x^2 - 4)

= 3x(x + 2)(x - 2)

so (x+2), (x - 2) and 3x are the factors of 3x^3 - 12x

answer:

x + 2

Answer:

x + 2

Step-by-step explanation:

given

3x³ - 12x ← factor out 3x from each term

= 3x(x² - 4) ← x² - 4 is a difference of squares, hence

= 3x(x - 2)(x + 2) ← fully factorised

hence x + 2 is a factor of the polynomial

Answer:

7 is the number of how many days are in a week. So 7 x 3 is 21. That is less than 24 days. 24 days is 3 weeks and 3 days.

Step-by-step explanation:

Well, there is 7 days in a week.

So, in 3 weeks, there are 3 times more days than 7 days.

Therefore, there are 21 days in three weeks, and 24 days are more than 21 days, or three weeks.

Answer:

y = 3

Step-by-step explanation:

The side labeled 'y' is the 'adjacent side' of the 30° angle.  The hypotenuse of this right triangle is 2√3.

The trig function relating this 30° angle, the 2√3 hypotenuse and the adj. side labeled 'y' is the cosine:

                 adjacent side          y

cos 30° = ---------------------- = --------- , and the value of cos 30° is (√3)/2.

                        2√3                2√3

Solving for y, we get 2√3 (√3)/2, or y = 2(3)/2, or y = 3

Answer:

y=-x+2

Step-by-step explanation:

Take two points and solve for the slope using: (y2-y1)/(x2-x1)=m

Then take the slope and plug it into the slope-intercept equation, y=mx+b.

Finally, take a xy pair and plug it into your equation to solve for b.

Answer:

The answer is 672.

Step-by-step explanation:

To solve this problem, first let's find the surface area of the rectangular prism. To do that, multiply each dimension with each (times 2 | just in case you don't understand [what I'm talking about is down below]).

8 x 8 x 2 = 128

8 x 11 x 2 = 176

8 x 11 x 2 = 176

Then, add of the products together to find the surface area of the rectangular prism.

176 + 176 + 128 = 480

Now, let's find the surface area of the square pyramid. Now, for this particular pyramid, let's deal with the triangles first, then the square. Like we did with the rectangular prism above, multiply each dimension with each other (but dividing the product by 2 | in case you don't understand [what i'm talking about is down below]).

8 x 8 = 64.

64 ÷ 2 = 32.

SInce there are 4 triangles, multiply the quotient by 4 to find the surface area of the total number of triangles (what i'm talking about is down below).

32 x 4 = 128.

Now, let's tackle the square. All you have to do is find the area of the square.

8 x 8 = 64.

To find the surface area of the total square pyramid, add both surface areas.

128 + 64 = 192.

Finally, add both surface areas of the two 3-D shapes to find the surface area of the composite figure.

192 + 480 = 672.

Therefore, 672 is the answer.

(w + 11)(w + 7)

Step-by-step explanation:

Consider the factors of the constant term ( + 77) which sum to give the coefficient of the w- term ( + 18)

The factors are + 11 and + 7, since

11 × 7 = 77 and + 11 + 7 = + 18

w² + 18w + 77 = (w + 11)(w + 7)
