On the first math test, Keiko answered 19 out of 25 questions correctly. On the
m_a_m_a [10]

Answer:

Keiko got a better answer on the test on her second test, and you could compare these two ratios as they are written.

Step-by-step explanation:

First: Convert each of the scores into percentages:

How do you convert ratios to percentages? Well, first we have to convert the ratio to a decimal or a fraction. Let's convert it to a fraction. So, 19 out of 25 will become \frac{19}{25}, and 17 out of 20 will become \frac{17}{20}. To convert a fraction to a percentage:

  • Divide the numerator by the denominator:

19 ÷ 25 = 0.76                                        AND                                    17 ÷ 20 = 0.85

  • Multiply your quotient by 100

0.76 x 100 = 76                                      AND                                 0.85 x 100 = 85

  • Add the percent sign

76%                                                          AND                                                   85%

Now the two quantities are easier to compare. We can obviously see that 85% is bigger [and better] than 76%. So, the ratio that equals 85% - 17 out of 20 - is a better grade.

The second question was: Can you compare these two ratios as they are written? Explain why or why not.

Yes, you can compare these two ratios, just find the [positive] difference between the amount that she scored and the total number of scores that could be gained.

25 - 19 = 6

20 - 17 = 3

Since the equation with 20 and 17 in it has a smaller difference, it is most likely to have a greater value [because that means that Keiko got more right and less wrong, which means a greater mark which is also a greater quantity].

Thanks,

Answer:

C. Strong Positive Linear Relationship

Step-by-step explanation:

If you were to draw a line through the points all of the points would be near the line therefore it has a strong correlation

The points are going upwards from left to right which indicates that the relationship is positive

From this information we can make a conclusion

This scatter plot has a strong positive linear relationship
