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
Answer:
Step-by-step explanation:
Gabrielhs 59 flowers because 43 + 16= 59.
X=number of pounds
y=cost of pound .
x+y=cost
55,000÷0.04
=1,375,000
55,000÷0.02
=2,750,000
2,750,000−1,375,000
=1,375,000 increase
