4200ft divided by 20 ft per second divided by 60 seconds is 1400 minutes
Answer:
P(x < 5) = 0.70
Step-by-step explanation:
Note: The area under a probability "curve" must be = to 1.
Finding the sub-area representing x < 5 immediately yields the desired probability.
Draw a dashed, vertical line through x = 5. The resulting area, on the left, is a trapezoid. The area of a trapezoid is equal to:
(average length)·(width, which here is:
2 + 5
----------- · 0.02 = (7/2)(0.2) = 0.70
2
Thus, P(x < 5) = 0.70
A tangent is always perpendicular to the radius at the point of tangency.
A right angle.
Y° = y₁° (opposite or Vertical angles), but y₁ = 45° corresponding angles,
then y = 45°
