Answer:

Option 3 (C)

Step-by-step explanation:

Given the scores of the students: 3, 4, 4, 5, 5, 6, 8, 10, 10, 12, 15, 18

To find the box plot that represents the data set, we need to find:

Min, Q1, median, Q3, and Max, which are all represented on a box plot.

Min = 3

Max = 18

Median = the average of the 6th and 7th data value = (6+8)/2 = 14/2 = 7

Q1 = the average of the 3rd and 4th data values = (4+5)/2 = 4.5

Q3 = the average of the 9th and 10th data values = (10+12)/2 = 11

The box plot that closely represented all these values is the box plot in option 3.

Is 3y=12 a linear function and if so, how would you graph it?
Fynjy0 [20]

find y which is 4 (12/3) then in would be a straight line  horizontally because y is going to always equal 4. Don't know if this helps but here you go. Have a good day.

What number line shows the solution set to this inequality? -2x + 9 < x − 9
UkoKoshka [18]

For the number line, an open circle will be drawn on the value of 6 and the arrow pointing to the right side.

<h3>Number line and inequality</h3>

Given the inequality expression as shown

-2x + 9 < x − 9

Collect the like terms

-2x - x < -9 - 9

-3x < -18

Divide through by -3

x > -18/-3

x > 6

For the number line, an open circle will be drawn on the value of 6 and the arrow pointing to the right side.

Which number line represents the solution set for the inequality <br> 3(8-4x) &lt; 6(x-5) ?
viktelen [127]

Answer:

Second number line(from top to bottom).

Step-by-step explanation:

We are given the following inequality:

3(8 - 4x) < 6(x - 5)

It is solved similarly to an equality, so:

24 - 12x < 6x - 30

-18x < -54

Multiplying by -1, the signal changes from < to >. So

18x > 54

x > \frac{54}{18}

x > 3

Thus the correct answer is given by the second number line.

Whats the answer to 45=x(14-x)
ElenaW [278]
45=x(14-x)\\ \\45=14x-x^2\\ \\x^2-14x+45=0\\ \\\Delta = b^{2}-4ac =  (-14)^{2}-4*1* 45=196-180=16 \\ \\x_{1}=\frac{-b-\sqrt{\Delta }}{2a} =\frac{14- \sqrt{16}}{2}=\frac{14-4}{2}= \frac{12}{2}=6\\ \\x_{2}=\frac{-b+\sqrt{\Delta }}{2a} =\frac{14+\sqrt{16}}{2}=\frac{14+4}{2}= \frac{18}{2}=9
