Answer:
In parametric form:
Step-by-step explanation:
We first find the mid point:
Then, a vector parallel to the z-axis is:
Then remember the equation of a line passing through point and parallel to the vector
is:
So, in this problem we get:
After combining the two vectors:
In parametric form:
Answer:
$28
Step-by-step explanation:
Given:
data = [22,30,35,25,25,20,27]
For eight night, the new list is:
new_data = [22,30,35,25,25,20,27,x]
Mean = 26.50
Mean Formula:
Therefore:
Multiply both sides by 8:
Solve for x:
Subtract 184 both sides:
Therefore, she will earn $28 in eighth night
The attachment below is the result of combining all eighth data as we get 26.5 through python language with numpy package.
