There are two shapes
rectangle and triangle
Rectangle area = Length × breadth
Triangle area = ( 1 / 2 ) × height × base
L = 12
W = 5
Area = 60
Height = 14
base = width of rectangle
base = 12
( 1 / 2 ) ( 12 ) ( 14 )
( 14 ) ( 6 )
84
Total area = 60 + 84
= 144

Step-by-step explanation:
Given:
Required:
To find the probability that the dart land will be in the shaded region.
Explanation:
Area of the circle is given by the formula:

Where r = radius
Thus the area of the circular region

The area of the square is given by the formula:

Thus the area of the given square

The probability of an event is given by the formula:

The probability that the dart land will be in the shaded region

Thus probability

Final answer:
Thus the probability that the dart land will be in the shaded region is 0.349.
Answer:
(69.94, 72.06)
Step-by-step explanation:
Confidence Interval formula = Mean ± z × Standard deviation/√n
Mean = 71 ounces
Standard deviation = 2.8 ounces
z score = 95% confidence interval = 1.96
Confidence Interval = 71 ± 1.96 × 2.8/√27
= 71 ± 1.96 × 0.5388602512
= 71 ± 1.0561660924
71 - 1.0561660924
= 69.943833908 ounces
Approximately = 69.94 ounces
71 + 1.0561660924
= 72.0561660924 ounces
Approximately = 72.06 ounces
95% Confidence Interval = (69.94, 72.06).
