The rate of change is -29/5x^2
Answer:
-213
Step-by-step explanation:
3|3-5|^2-(-15)^2
3(4)-225

The dot-plot for the data is sketched at the end of this answer.
--------------------------
- The dot plot shows the <u>number of times each measure appears in the data-set.</u>
<u />
- 68 appears once, thus it is 1 in the dot-plot.
- 69 appears three times, thus it is 3 in the dot-plot.
- 70 appears once, thus it is 1 in the dot-plot.
- 71 does not appears, so it is 0.
- 72 appears once, thus it is 1 in the dot-plot.
- 73 appears five times, so it is 5 in the dot-plot.
- 74 appears once, thus it is 1 in the dot-plot.
- 75 does not appears, so it is 0.
- 76 appears twice, thus it is 2.
- 77 appears once, so it is 1.
