Answer:
Step-by-step explanation:
Hello
A1 = (B + b) x h / 2
A1 = (8 + 2) x 5 / 2
A1 = 10 x 5 / 2
A1 = 25 cm^2
A2 = L x l
A2 = 6 x 8
A2 = 48 cm^2
A = A1 + A2
A = 25 + 48
A = 73 cm^2
Answer:
Yes, because 29.5 lies within the interval.
Step-by-step explanation:
Since the given interval of (28, 32) inches has an 80% confidence level. It is plausible to estimate with 80% certainty that the mean height of all adult miniature horses falls within that interval.
A height of 29.5 belongs to the interval:
28≤ 29.5 ≤ 32
Therefore, based on the confidence interval, the belief that the population average height is 29.5 inches is plausible

Answer:
60
Step-by-step explanation:
To find the area of a triangle, multiply the base and height, then divide by two
The center triangle's area is (5*6)/2, which is also 15.
Since all the triangles are congruent, multiply 15 by 4 to get the total surface area, which is 60
