Answer: 25 tables.

Step-by-step explanation:

5 • 10*2= 500 (10*2= 100, then 100 times 5)

2 • 10*1= 20 (10*1= 10, then times 2)

Therefore a cafeteria can seat 500 students. Each table had 20 seats.

Divide 500/20 and get 25.

Hope this helps

In Exercises 27 and 28, find the domain of the function
Natali5045456 [20]

                                             Question 27

The graph on question 27 indicates that there are three points with the locations such as:

  • (2, 6)
  • (4, 12)
  • (6, 18)

In other words, there are three points that lie on the graph with the x-values such as:

{(2, 6), (4, 12), (6, 18)}

We know that the domain includes the set of x-values.

Hence, the domain of the function is:

  • Domain: {2, 4, 6}

Since the points are not connected between them. In other words, there is not a continuous line.

Thus, the function represented on the graph has a discrete domain.

                                        Question 28

The graph on question 27 indicates that the line segment with the end-points (0, 25) and (7, 20).

Since there is a continuous line between the points from x = 0 to x = 7.

Thus, the domain of the line function is:

  • Domain: {0, 1, 2, 3, 4, 5, 6, 7}

As the line segment is a continuous line. Thus, the domain is continuous.

X^2 + 6x - 18 solve for x​
Simora [160]

Answer:

x = - 3  ± √27 or if you want it in decimal form correct to  nearest hundredth:

x = -8.20, 2.20.

Step-by-step explanation:

x^2 + 6x - 18 = 0

this will not factor so we use completing the square:

x^2 + 6x = (x + 3)^2 - 9 so:

(x + 3)^2 - 9 - 18 = 0

(x + 3)^2 = 27

x+ 3 = ±√27

x = - 3  ± √27

How can one determine the median of a data set?
rjkz [21]

Answer:

A

Step-by-step explanation:

The median value on a data set is the value that accumulates 50% of the values at its left and the other 50% at its right. In other words, it is the value that divides the data set in two halves. Lets see each option and find this value:

B: By doing it we are finding the mode, the value that is repeated most. This is incorrect!

C: By doing this we are finding the mean, the average or the arithmetic mean. This is incorrect!

D: This gives us the range, not the median. This is incorrect!

Finally, A is correct, as this is what we said at the beginning of the text. Ordering the values and finding the one the splits the data set in 2 equal parts is the median.
