Answer:
Scale factor = 2, x = 3 cm
Step-by-step explanation:
The scale factor is 2 because you can see that in the second figure you multiply the sides from the first one by 2.
Using the scale factor 2, you can multiply 1.5 * 2 = 3 for x.
The equation is y = mx + b, where m is the slope, and b is the y-intercept. Our equation is y = -3x - 5, but it is minus, not plus, and this is because our y-intercept is negative. So, knowing this, we can determine that our y-intercept is -5.
Using the dot plot and statistical concepts, it is found that the correct option is:
- Their means will be most affected because this value will be an outlier.
<h3>What is a dot plot?</h3>
- The dot plot shows the <u>number of times each measure appears in the data-set.</u>
In this problem, for both Walter and Janine, the dot plots are cluster between 80 and 90, which means that their grades are in this range.
- Hence, for both, a grade of 65 would be an outlier, and the measure that is most affected by outliers is the mean.
Hence, the correct option is:
- Their means will be most affected because this value will be an outlier.
