The number of solutions for the given two line graph is; D: One Solution

<h3>How to Interpret Parallel Line graphs?</h3>

Since the two lines in the graph are not parallel, it means that both lines will intersect at some point.

Now, from the graph, we can see the following highlights;

The x-coordinate of the point of intersection is at x = 1.5

The y-coordinate of the point of intersection is at y = -0.75

Thus, the ordered pair that represents the solution is (1.5,-0.75)

Thus, the two line graph has only one solution

Answer:

Identifying at least one confounding variable that undermines the conclusion drawn in the fictional study is:

All students took the same comprehensive test.

Step-by-step explanation:

In a study, an independent variable causes an effect on the dependent variable. But a confounding variable is the variable that influences the independent variable as well as the dependent variable. If this third variable is not controlled, it might lead the researcher to make a wrong estimate of the relationship that exists between the independent variable and the dependent variable.

Dvinal [7]

Hey there!

xz ÷ y

= 10(-5) ÷ -2

= -50 ÷ 2

= -25

Therefore, your answer is: -25

Good luck on your assignment and enjoy your day!

If 10% of a number is 7, what is 80% of the number?

Zanzabum

Answer:

Step-by-step explanation:

Note that 80% is 8 times 10%.

Thus, we could start with "If 10% of a number is 7" and multiply both quantities by 8: "80% of a number is 56."

Think:

10% of a number is 7,

20% is 14,

50% is 35,

70% is 49, and

80% is 56.
