2 fourths is a half so multiply 2 by 3 to get your answer that is 6
85 1/4 / 14
= 341/4* 1/14
= 341/56
= 6 5/56
The final answer is 6 5/56~
Answer:
12
Step-by-step explanation:
Mean is the average of all the numbers. Add up all the numbers then divide by how many you have.
Okay, so first you draw a picture and let x be the distance from point D to the rest stop. Then the distance from point to the rest stop is 8 - x
You know that the length of the new trail is y + z, where y is the distance from Ancaster to the rest stop and z is the distance from Dundas to the rest stop.
Now by the Pythagorean theorem, y^2 = 4^2 + x^2 and z^2 = 6^2 + (8 - x) ^2
So take square roots of these, add them, and minimize.
Note: I am assuming the path is perfectly straight, otherwise this approach fails.
Y(hat) = 14x + 1
y(hat) = 14(12) + 1
y(hat) = 168 + 1
y(hat) = 169
Residual = y - y(hat)
12 - 169
Res = - 157
