First, let’s begin with part A of the question. To find the mean, we must find the average of Rolinda’s test scores by adding them all together and then dividing the sum by 5 (the number of test scores). This is shown below:
(85 + 85 + 60 + 62 + 59) / 5
351/5
70.2
Therefore, the mean of Rolinda’s test scores is 70.2.
Next, we should find the median, or the middle number of the sequence after we order the numbers from smallest to largest. This is shown below:
59, 60, 62, 85, 85
Since 62 is the middlemost number in the list, the median is 62.
Finally, we must find the mode, or the most common number in the list. Since 85 is the only number that occurs more than once, we know that the mode is 85.
Next, we move on to Part B. The measure that supports Rolinda’s claim that she is doing well in her Spanish class is the mode, because it is the highest measure out of the three.
The answer to Part C is as follows: This is misleading because the mode is not an accurate representation of all of Rolinda’s test scores and the range that they cover, it only represents Rolinda’s highest score, which she happened to score twice.
Hope this helps!
Yes the problem is true and 56 is a solution
Answer:
See below
Step-by-step explanation:
- Find a point on the line where it touches a gridpoint and start from there. Slope is defined as rise/run, so from that point you either go up or down for rise, and left or right for run to find another point closest where the line touches a gridpoint.
- A graph with a slope that looks like \ will be negative and a slope that looks like / will be positive
5. 3/2
6. Undefined
7. 7/2
8. 3/6 simplifes to 1/2
9. -1/3
10. -2/3
Please consider marking brainliest :) I can correct mistakes if needed.
Answer:
9 11/12
Step-by-step explanation:
He is currently 47.
56-9=47 and if you switched it around it would be 47+9=56 so the answer is 47.
