Answer:
110
Step-by-step explanation:
Let x = rate #1 and then 155-x=rate #2.
15x + 5(155-x) = 1225
15x - 5x + 775 - 1225
10x = 450
x = 45, second rate is 110
Answer:
3.00
Step-by-step explanation:
USL = 350+18 = 368
z = (USL-Mean)/6*σ = (368-350)/6*σ
σ = 3/0.9999966 = 3.00 (approx)
Answer:
y= -4x+4
Step-by-step explanation:

The measure of an exterior angle in a polygon with n sides is given by:

So, for n = 20, we have the measure of the exterior angles of the polygon with 20 sides:

Now, to find the sum of all exterior angles, let's multiply the exterior angles by the number of sides of the polygon:

Therefore the sum is equal to 360°, correct option: B.
(The sum of exterior angles of a polygon with n sides is always equal to 360°)
