No this is not a function because it does not pass the vertical line test. (Which is where you would see if any one vertical line would touch a line twice)
The slope is m=-1
Because the formula is y=mx+b (b is the intercept) (or replace 0 with x so that will be y=7)
And the Y intercept is 7 :)
I hope this helped!
Answer:
x = 60°
y = 50°
Step-by-step explanation:
✅x = 180° - (50° + 70°) (sum of interior angles of a triangle theorem)
x = 180° - 120°
x = 60°
✅Based on the exterior angle theorem, the sum of the opposite interior angles of a triangle = the exterior angle.
Therefore,
50° + 60° = x + y
Plug in the value of x
50° + 60° = 60° + y
110° = 60° + y
y = 110° - 60°
y = 50°
The expected assembly time is the middle of the range of the uniform distribution, 8 minutes.
