Answer:
The scale used to draw the plan is 1: 200.
Step-by-step explanation:
Given that two points A and B on a plan represent two localities 12 m apart, to determine, given that the segment AB is 6 cm long, the scale used to draw the plan, the following calculation must be performed:
12 m = 12 cm x 100 = 1200 cm
1200/6 = 200
Therefore, the scale used to draw the plan is 1: 200.
When a scatter plot shows a positive association means that there is a linear correlation with a positive slope between the two variables. This correlation can be weaker or stronger (depending on the value of the correlation).
If there is a linear correlation between the two variables, the relation is then a direct proportionality (with slope positive or negative).
Hence, it is always true that <span>a scatter plot that shows a positive association suggests that the relationship is proportional.</span>
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!
