Answer:
Point E is given by ![\left ( \frac{3mx_1+4x_0}{7},\frac{3y_1+4y_0}{7} \right )](https://tex.z-dn.net/?f=%5Cleft%20%28%20%5Cfrac%7B3mx_1%2B4x_0%7D%7B7%7D%2C%5Cfrac%7B3y_1%2B4y_0%7D%7B7%7D%20%5Cright%20%29)
Step-by-step explanation:
Let points C and D be
and let point E divides it in ratio
.
Then coordinates of point E are given by ![\left ( \frac{mx_1+nx_0}{m+n},\frac{my_1+ny_0}{m+n} \right )](https://tex.z-dn.net/?f=%5Cleft%20%28%20%5Cfrac%7Bmx_1%2Bnx_0%7D%7Bm%2Bn%7D%2C%5Cfrac%7Bmy_1%2Bny_0%7D%7Bm%2Bn%7D%20%5Cright%20%29)
Put
Point E is given by ![\left ( \frac{3mx_1+4x_0}{3+4},\frac{3y_1+4y_0}{3+4} \right )=\left ( \frac{3mx_1+4x_0}{7},\frac{3y_1+4y_0}{7} \right )](https://tex.z-dn.net/?f=%5Cleft%20%28%20%5Cfrac%7B3mx_1%2B4x_0%7D%7B3%2B4%7D%2C%5Cfrac%7B3y_1%2B4y_0%7D%7B3%2B4%7D%20%5Cright%20%29%3D%5Cleft%20%28%20%5Cfrac%7B3mx_1%2B4x_0%7D%7B7%7D%2C%5Cfrac%7B3y_1%2B4y_0%7D%7B7%7D%20%5Cright%20%29)
Now plot point E.
<span>In order to find the average, you have to find the total, and then divide by the amount of days, which in this case is 5. The total is 395/5 = 79. Therefore, the average number of pies sold each day is 79</span>
Yes, because it's on the x axis.
