Answer:
106.6 cm²
Step-by-step explanation:
The area of a triangle is given by the formula ...
A = 1/2bh
A = 1/2(16.4 cm)(13 cm) = 106.6 cm²
The area of the triangle is 106.6 square centimeters.
The formula to find the area of a sector is:
A =
In this case:
Degree = 40
Radius = 8
^^^Plug these numbers into the formula given above
A =
Solve
A = π8²
A = π64
A =
A = 7.1111111π
When rounded:
7.1π is the area of the sector

Answer:
The best estimate for the true proportion of all such students who own a Texas Instruments calculator is 0.3.
Step-by-step explanation:
The estimate of the true proportion of all students who own a Texas Instruments calculator is the number of students who own a Texas Instruments Calculator divided by the total number of students.
6 students own a Texas Instruments Calculator
20 total students
p = 6/20 = 0.3
The best estimate for the true proportion of all such students who own a Texas Instruments calculator is 0.3.
