Answer:

20%

Step-by-step explanation:

If he rolled the dice 50 times and got the following result

Sum of the number-Number of rolls

2-1

3-4

4-3

5-6

6-7

7-10

8-7

9-5

10-4

11-2

12-1

What percentage of the rolls resulted in a sum of 7?

Percentage of the rolls that resulted in a sum of 7 = 100% × (number of times the sum of 7 showed up)/(total number of rolls)

From the data presented above,

number of times the sum of 7 showed up = 10

total number of rolls = 50

Percentage of the rolls that resulted in a sum of 7 = 100% × (10/50) = 20%

On a piece of paper, graph f(x)= {x if x<2 2 if x>2}
r-ruslan [8.4K]

Answer:

  see below

Step-by-step explanation:

The graph has two parts. There is one line for x < 2. It has a slope of 1 and a y-intercept of 0.

The line for x > 2 is the horizontal line x=2.

The point at x=2 is not defined by the function you have posted here, so there is a "hole" in the graph at that point.

Which of the following graphs shows a pair of lines that represent the equations with a solution (−5, 2)? (PLEASE HELP ASAP, DUE
gizmo_the_mogwai [7]

Using a system of equations, it is found that the third graph shows a pair of lines that represent the equations with a solution (−5, 2).

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

The solution of the system on a graph is the intersection of two lines. The third graph has an intersection at (-5,2), hence it is the answer to this question.
