Answer:
area of rectangle : 180 sq ft
area of triangle : 30 sq ft
area of entire composite figure : 210 sq. ft
Step-by-step explanation:
rectangle : 15*12= 180
triangle : 15*4=60 /2 = 30
entire : 180 + 30 = 210
Answer: 95% confidence interval would be (0.344,0.456).
Step-by-step explanation:
Since we have given that
n = 295
x = 118
so, 
At 95% confidence, z = 1.96
So, margin of error would be
so, 95% confidence interval would be
Hence, 95% confidence interval would be (0.344,0.456).
Answer:
The answer would be 129°
Step-by-step explanation:
We know that <em>AZC </em>is a right angle so you would add the 90° ( which is equal to a right angle) to 39° to get your answer :)
The actual height is 306 inches by 10 inches. In simple terms, it is 25 1/2 ft tall and 15 ft wide.
Volume of the pyramid:
V = 1/3 · B · h
B = 8 ft²
tan 30° = height / 7√3
1/√3 = height / 7√3
height = 7 ft
V = 1/3 · 8 · 7 = 18.67 ft³ ≈ 19 ft³
Answer : D ) 19 ft³
