Answer:
14
Step-by-step explanation:
Answer: Median
You can't use the mode in here, since there are no repeated numbers. But You can use mean and median. If you use the mean, you will get 57. If you use the median, you will get 75.5. This means that the median will give you the best grade.
Explanation:
Mode: The most repeated number.
Median: The Middle number of statistics.
Mean: The average of all numbers.
Answer:
![\frac{AC}{BC}=\frac{DF}{EF}](https://tex.z-dn.net/?f=%5Cfrac%7BAC%7D%7BBC%7D%3D%5Cfrac%7BDF%7D%7BEF%7D)
Step-by-step explanation:
The figure given has two similar triangles: ΔABC and ΔDEF. Although the triangles are similar, their orientation is different and ΔDEF is flipped. Since the triangles are similar, their side lengths are proportional to each other. Given the orientation of the triangles, we can still see that the diagonal (hypotenuse) for the larger triangle is AC and the smaller is DF. The only answer that matches these up proportionally is the third one. Looking at the second side, BC, we can see that this matches up to the longer leg of EF on the smaller triangle. Final answer being:
![\frac{AC}{BC}=\frac{DF}{EF}](https://tex.z-dn.net/?f=%5Cfrac%7BAC%7D%7BBC%7D%3D%5Cfrac%7BDF%7D%7BEF%7D)
Use the slope formula to find the slope m.
m= 2/3
