Rolinda's first five Spanish test scores are 85, 85, 60, 62, and 59.
a. Find the mean, median and mode of the scores. Round to the nearest tenth, if necessary.*
b. Which of these measures best supports Rolinda's claim that she is doing well in her Spanish class?
c. Why is Rolinda's claim misleading?
*I already figured that out. Thanks!
Ms. Sue, Writeacher, Reed, Damon please help me guys!
Actually, A is not posted correctly here. 70.2 is the mean but the other two were not posted.
Sum: 351 85 + 85 + 60 + 62 + 59
Min 59
Max 85
Range 26 85 - 59
Median 62
Mode 85
Mean 70.2
Median=62 Mode=85 Mean= 70.2
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
The answer to A is 70.2. To find the mean, you add the number and then divide that by the number of number that are listed.
85 + 85 + 60 + 62 + 59 = 351
351/ 5 = 70.2
I think b is 85
And I think to c, the answer is: Her claim is misleading because the score of 85 is her first test score, and the scores slowly decrease after that.

1. a. Mean: 70.2 Median: 62 Mode: 85
b. Mode, because its the highest out of the three.
c. 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.
Wow helper, 4 hours ago?
What is the Answer To A?
thx I better get this right
A. For the mean you add all the numbers and divide it by 5. gets you 70.2
now for the median it is the average number so 62
Mode is the number you seen more often 85
B. Mode since it is the larger number
C. The claim is misleading because mode represents there highest score and Rolinda scored it twice

Rolinda’s first five Spanish test scores are 85, 85, 60, 62, and 59.
a. Find the mean, the median, and the mode of Rolinda’s Spanish test scores. Round your answers to the nearest tenth, if necessary.
b. Which of these measures best supports Rolinda’s claim that she is doing well in her Spanish class?
c. Why is Rolinda’s claim misleading?
a. The mean of Rolinda’s Spanish test scores is 70.2, the median is 62, and the mode is 85.
b. The mode best supports Rolinda’s claim that she is doing well in her Spanish class, because it is the highest measure out of the three.
c. Rolinda’s claim is misleading because the mode, which is the highest score of 85, only represents one part of her scores. It does not represent the range and variation of all her scores.
thx bot
You're welcome! Don't hesitate to ask if you have any other questions.
can you tell me the steps to the answers
Certainly! Here are the steps to the answers:
a. Mean:
To find the mean, you add up all the values and then divide the sum by the number of values. In this case, you would add up Rolinda's five Spanish test scores:
85 + 85 + 60 + 62 + 59 = 351
Then, you would divide 351 by 5 to get the mean:
351 / 5 = 70.2
Median:
To find the median, you order the values from smallest to largest and then find the middle number. In this case, Rolinda's scores in order are:
59, 60, 62, 85, 85
The middle number is 62, so that is the median.
Mode:
To find the mode, you find the value that occurs most frequently. In this case, there are two values that occur most frequently, which are both 85. Therefore, the mode is 85.
b. The mode best supports Rolinda’s claim that she is doing well in her Spanish class, because it represents the highest score, which is a good indication of doing well.
c. Rolinda’s claim is misleading because the mode only shows the most frequently occurring score, which is 85, and doesn't take into account the range of scores and overall performance.

However, some of Nike's most iconic and popular shoe models include the Air Jordan (basketball shoes), Air Max (running shoes), and the Nike Air Force 1 (casual shoes). These shoes have had a significant impact on the sneaker industry and popular culture, and have been continually updated and improved upon over the years. Ultimately, the "best" shoe for someone will depend on their individual needs, style preferences, and intended use.
when were guns invented, and if so, how
Guns, which are also called firearms, were invented in China in the 9th century AD, during the Tang Dynasty. The first gun was a simple device, called a "fire lance," that consisted of a bamboo tube filled with gunpowder and shrapnel, ignited by a fuse. Over time, guns evolved to become more sophisticated, with metal barrels and mechanisms to load and fire bullets more efficiently.
The Renaissance period in Europe saw significant advances in gun technology, with the development of the matchlock, wheel-lock and flintlock mechanisms that made firearms more reliable and effective. In the 19th century, the invention of the percussion cap, followed by self-contained cartridges later on, made guns more easily portable and usable.
Today, guns are widely used and are an integral part of many military forces, police departments, hunting, and recreational activities. However, it's essential to acknowledge that, while guns have contributed to technological advances and have served a purpose in their development for years, they can also be dangerous and should be handled responsibly, with careful consideration to safety, regulation and legal guidance.
ok, thank you
You're welcome! Do let me know if you have any other questions.
Why is Rolinda’s claim misleading?
Rolinda's claim is misleading because it only takes the highest score of 85 into consideration, represented by the mode of her test scores. Her claim does not provide an accurate representation of her overall performance as the other scores indicate a significant drop in her performance.
The mean of Rolinda’s test scores is 70.2, which is considerably lower than 85. The median score of 62 suggests there is a range of scores that are lower than 85, further indicating a decline in performance.
Therefore, using only the mode as a measure of performance is misleading because it disregards the range and variation between the other test scores. To have a more accurate representation of Rolinda's overall performance, we should consider and evaluate all scores, not just the highest one.
