Answer:
Step-by-step explanation:
The area of the shape is the sum of three sections
<u>1. Rectangle</u>
<u>2. Bigger semicircle</u>
- A = 1/2π(14/2)² = 76.96 ≈ 77 in² (rounded)
<u>3. Smaller semicircle</u>
- A = 1/2π(5/2)² = 9.8174 ≈ 10 in² (rounded)
<u>Total area:</u>
Area: 171ft^2
Explanation:
The triangles area is 24ft^2
The large rectangle is 120ft^2
The small rectangle is 27ft^2
24+120+27= 171ft^2
Answer:
98% Confidence interval: (26.939,42.461)
Step-by-step explanation:
We are given the following in the question:
Sample mean, = 34.7 bushels per acre
Sample size, n = 9
Alpha, α = 0.05
Sample standard deviation, s = 8.04 bushels per acre
Degree of freedom = n - 1 = 8
98% Confidence interval:
Putting the values, we get,
is the required confidence interval for the true mean yield.
