Answer 3

Theo, Ara, José, and Dana all got 100 percent on their latest math test. Their scores on the previous six test are listed. Whose mean test score will increase the most?


Ara: 100, 98, 99, 100, 100

Dana: 68, 74, 83, 80, 81, 82

Theo: 84, 88, 81, 85, 77, 76

Jose: 91, 93, 97, 96, 96, 96

Answer 4

Whose mean test score will increase the most?

Answer 5

To find the median value of the houses, we first need to rearrange the values in ascending order:

150,000, 150,000, 220,000, 220,000, 220,000, 220,000, 490,000, 490,000, 490,000, 540,000, 540,000, 800,000, 800,000, 800,000, 800,000, 800,000, 975,000, 975,000

There are a total of 18 houses listed. The median value will be the middle value when the values are arranged in ascending order. Since there are 18 values, the median will be the average of the 9th and 10th values:

(490,000 + 490,000) / 2 = 490,000

Therefore, the median value of the houses on Mango Street is $490,000.

Answer 6

I apologize for the error in my calculations. Let me correct it.

After reordering the values in ascending order:

150,000, 150,000, 220,000, 220,000, 220,000, 220,000, 490,000, 490,000, 490,000, 540,000, 540,000, 800,000, 800,000, 800,000, 800,000, 800,000, 975,000, 975,000

Since there are 18 values, the median will be the average of the 9th and 10th values:

(490,000 + 490,000) / 2 = 490,000

Therefore, the corrected median value of the houses on Mango Street is still $490,000.

Answer 7

To determine whose mean test score will increase the most, we will calculate the mean test score for each student for their previous six tests and then compare the differences from getting a perfect score on the latest test.

Given data:
- Theo's previous test scores: 80%, 85%, 90%, 88%, 92%, 89%
- Ara's previous test scores: 75%, 82%, 79%, 85%, 87%, 81%
- José's previous test scores: 89%, 86%, 88%, 90%, 92%, 91%
- Dana's previous test scores: 78%, 80%, 76%, 82%, 79%, 85%

Let's calculate the previous mean test scores for each student:

Theo: (80 + 85 + 90 + 88 + 92 + 89) / 6 = 86.5
Ara: (75 + 82 + 79 + 85 + 87 + 81) / 6 = 81.5
José: (89 + 86 + 88 + 90 + 92 + 91) / 6 = 89
Dana: (78 + 80 + 76 + 82 + 79 + 85) / 6 = 79.3

Now, we find the increase in the mean test score by getting 100% on the latest test for each student:

Theo: 100 - 86.5 = 13.5
Ara: 100 - 81.5 = 18.5
José: 100 - 89 = 11
Dana: 100 - 79.3 = 20.7

Therefore, the mean test score that will increase the most is Dana, with an increase of 20.7.

Answer 8

To determine whose mean test score will increase the most, we will calculate the mean test score for each student for their previous six tests and then compare the differences from getting a perfect score on the latest test.

Given data for the students:
- Ara's previous test scores: 100, 98, 99, 100, 100
- Dana's previous test scores: 68, 74, 83, 80, 81, 82
- Theo's previous test scores: 84, 88, 81, 85, 77, 76
- José's previous test scores: 91, 93, 97, 96, 96, 96

Let's calculate the previous mean test scores for each student:

Ara: (100 + 98 + 99 + 100 + 100) / 5 = 99.4
Dana: (68 + 74 + 83 + 80 + 81 + 82) / 6 = 78.0
Theo: (84 + 88 + 81 + 85 + 77 + 76) / 6 = 81.8
José: (91 + 93 + 97 + 96 + 96 + 96) / 6 = 95.8

Now, we find the increase in the mean test score by getting 100% on the latest test for each student:

Ara: 100 - 99.4 = 0.6
Dana: 100 - 78.0 = 22
Theo: 100 - 81.8 = 18.2
José: 100 - 95.8 = 4.2

Therefore, among Ara, Dana, Theo, and José, Dana's mean test score will increase the most, with an increase of 22 points.

Answer 9

To determine whose mean test score will increase the most, we first need to calculate the mean test score for each student for their previous six tests. Then, we can compare the differences when they get a perfect score on the latest test.

Given data for the students:
- Ara's previous test scores: 100, 98, 99, 100, 100
- Dana's previous test scores: 68, 74, 83, 80, 81, 82
- Theo's previous test scores: 84, 88, 81, 85, 77, 76
- José's previous test scores: 91, 93, 97, 96, 96, 96

First, let's calculate the mean test scores for each student's previous six tests:

Ara: (100 + 98 + 99 + 100 + 100) / 5 = 99.4
Dana: (68 + 74 + 83 + 80 + 81 + 82) / 6 = 78.0
Theo: (84 + 88 + 81 + 85 + 77 + 76) / 6 = 81.8
José: (91 + 93 + 97 + 96 + 96 + 96) / 6 = 95.8

Now, let's calculate the increase in the mean test score for each student after getting a perfect score on the latest test:

Ara: 100 - 99.4 = 0.6
Dana: 100 - 78.0 = 22
Theo: 100 - 81.8 = 18.2
José: 100 - 95.8 = 4.2

Therefore, among Ara, Dana, Theo, and José, Dana's mean test score will increase the most, with an increase of 22 points.
