Iwill give brainliest, amazing rating, and for answer!

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!

First list the grades from smallest to biggest:

59, 60 , 62 , 85, 85

a) The mean is the average: add the scores together and divide by 5

Mean = 59 + 60 + 62 + 85+85 = 351

351/5 = 70.2

Mean = 70.2

The median is the middle value, since there is an odd amount of scores, the median would be the 3rd score, which is 62.

The mode is a number which is repeated the most, in this case there are 2 scores of 85, so 85 is the mode.

b) The mean, since it is the average is the best way for her to know how she is doing in class.

c) It's misleading because the average is only 70.2, which although is a passing grade it isn't a high grade, and it also looks like here test scores have been going down instaed of up or the same.

take the top number and divide it by a the bottom number

1/2 1 divied by 2 = .5
