Use the image to answer the question.

An illustration shows a number line with arrows on both ends ranging from 1 to 13 in one unit increments. Dots are plotted above the number line to indicate frequency. There is 1 dot over 2; 2 dots over 7; 4 dots over 8; 4 dots over 9; 3 dots over 10; 4 dots over 11; 3 dots over 12; and 2 dots over 13. There are no dots over the numbers 1, 3, 4, 5, and 6.

What number is the outlier in this dot plot?

To find the rational number between 7–√ and 8–√, we need to add the two numbers and divide by 2.

(7–√ + 8–√)/2 = (15–2√)/2 = 15/2 – √2

Therefore, the rational number with a denominator of 7 that is between 7–√ and 8–√ is 15/2 – √2.

To find the range of temperatures, we need to subtract the lowest temperature from the highest temperature.

Highest temperature: 39°F
Lowest temperature: 18°F

Range = Highest temperature - Lowest temperature
Range = 39°F - 18°F
Range = 21°F

Therefore, the range of temperatures over the seven days is 21°F.

To determine Mario's average test score, we need to add up all the test scores and divide by the number of tests.

Test #1: 70
Test #2: 82
Test #3: 95
Test #4: 81
Test #5: 78
Test #6: 82
Test #7: 93

Total score = 70 + 82 + 95 + 81 + 78 + 82 + 93 = 581

Number of tests = 7

Average test score = Total score / Number of tests
Average test score = 581 / 7

The average test score is approximately 83.

Therefore, the correct answer is 83.
Answered by GPT 3.5
To find the score Mario needs to achieve an average of 85, we need to consider the current total score and number of tests, as well as the desired average.

Test #1: 70
Test #2: 82
Test #3: 95
Test #4: 81
Test #5: 78
Test #6: 82
Test #7: 93

Total score = 70 + 82 + 95 + 81 + 78 + 82 + 93 = 581

Number of tests = 7

Desired average = 85

We can solve the equation:

(581 + x) / 8 = 85

Multiplying both sides by 8:

581 + x = 680

Subtracting 581 from both sides:

x = 99

Therefore, Mario needs to score 99 on the next test in order to achieve an average of 85.

The correct answer is 99.

To determine how many numbers in the dataset will be in the bin that goes from 62 to 64, we need to count the numbers within that range.

The numbers in the dataset that fall within the range of 62 to 64 are: 64, 64, 62.

Therefore, there are 3 numbers in the dataset that will be in the bin from 62 to 64.

The correct answer is 3.
