Out of 124 students, only 31 students are taught to buy their lunches in the cafeteria.

<u>Step-by-step explanation:</u>

It is given that,

The 25% of 124 students are taught to buy their lunches in cafeteria.

Therefore, the total number of students taught to buy their lunches in cafeteria is 25% of 124.

<u>To find the number of students who are capable to buy lunches in cafeteria:</u>

  • Replace the % symbol into the numeric form.
  • The % is represented by 1 ÷ 100.

The 25% of 124 students is written as,

⇒ 25×(1/100)×124

⇒ (1/4)×124

⇒ 31

The number of students taught to buy lunches in the cafeteria out of 124 students is 31 students.

Find the value of x needed to make the equation true.<br> 8x – 4 = 13x + 6
Kipish [7]

Answer:

x = -2

Step-by-step explanation:

<u><em>First, you need to subtract 8x from both sides:</em></u>

8x – 4 = 13x + 6

-8x         -8x

____________

-4 = 5x + 6

<em><u>Then, subtract 6 from both sides:</u></em>

-4 = 5x + 6

-6         - 6

________

-10 = 5x

<u><em>Lastly, divide both sides by 5:</em></u>

-10 = 5x

-2 = x

Whats a equation for a linear function that passes through the point (3,7) and (0,13).
allsm [11]

Answer:

Step-by-step explanation:

First do your x2-x1/y2-y1 to find slope, which is 0-3/7-13 = -3/-6 = 1/2

Then plug into point slope form (choose either point)

(y-13) = 1/2(x-0)

OR

(y-7) = 1/2(x-3)

The following are score earned by 15 college students on a 20-point math quiz. (a) calculate the mean, median, and mode scores.
Softa [21]

Answer:

(a) 12.87; 14; 18; (b) median  

Step-by-step explanation:

(a) Statistics

(i) Mean

The mean is the sum of all the data points divided by the number of points.

\begin{array}{rcl}\text{Mean} & = & \dfrac{0 + 2 + 3 + 12 + 12 + 13 + 14 + 14 + 15 + 15 + 18 + 18 + 18 + 19 + 20}{15}\\\\& = & \dfrac{193}{15}\\\\& = & \mathbf{12.87}\\\end{array}

(ii) Median

The median is the middle value in your list of observations.

0, 2, 3, 12, 12, 13, 14, 14, 15, 15, 18, 18, 18, 19, 20

Median = 14

(iii) Mode

The mode is the value that appears most often in your list of observations.

0, 2, 3, 12, 12, 13, 14, 14, 15, 15, 18, 18, 18, 19, 20

Mode = 18

(b) Most representative measure

The mean is dragged down by three low values. The median is the measure that is most representative of the data.

The histogram below shows the distribution of your data.

Help plz what is 7-6v=-5-8v
kirill115 [55]

<u><em>v=-6 is the right answer. </em></u> First you had to subtract by 7 from both sides of equation, and it gave us, 7-6v-7=-5-8v-7. And then simplify, and it gave us, -6v=-8v-12. You can also add by 8v from both sides of equation, and it gave us, -6v+8v=-8v-12+8v. Next simplify, and it gave us, 2v=-12. Then you divide by 2 from both sides of equation, and it gave us, \frac{2v}{2}=\frac{-12}{2}. And finally simplify, and it gave us the answer is <u><em>v=-6 is the right answer.</em></u> Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie
