Answer:
13 units
Step-by-step explanation:
Use the distance formula, d = , where (x2, y2) and (x1, y1) are two different points on the line.
Plug in the values:
d =
d =
d =
d =
d =
d = 13
Answer:
C. The chance to be selected into the sample was the same for all veterinarians
Answer:
The smaller board would be 2.75 feet and the longer one would be 10.25 feet.
Step-by-step explanation:
In order to find this, assume the shorter board is equal to x. Next, we would know that the longer board would be equal to x + 7.5. Using these two assumptions, we can add the lengths together, set equal to 13 and then solve for x.
x + (x + 7.5) = 13
2x + 7.5 = 13
2x = 5.5
x = 2.75
Now that we have the length of the shorter board, we can add 7.5 to it to get the larger one.
2.75 + 7.5 = 10.25
