Answer:
0.159
Step-by-step explanation:
Given that:
Sample size (n) = 100
Population mean(pm) = 50
Standard deviation (s) = 8
Probability that Sample mean (m) will be greater Than 50.8
Using the relation :
(sample mean - population mean) / (standard deviation /sqrt(n))
P(m > 50.8)
Z = (50.8 - 50) / (8/ sqrt(100))
Z = 0.8 / (8/ 10)
Z = 0.8 / 0.8
Z = 1
P(Z > 1) = 0.15866 ( Z probability calculator)
Hence,
P(Z > 1) = 0.159 ( 3 decimal places)

Answer:
7y8.9 ft²
Step-by-step explanation:
Easy way:
Rotate the triangle so that the 12.1 ft side in on the bottom becomes the base.
Drop a line from the top down perpendicular to the 12.1 ft base. That makes a right triangle.
sin 71 = height/13.8
0.9455 = height/13.8
height = 13.05 ft
Area = bh/2 = (12.1)(13.05)(0.5) = 78.9 ft²
Total = principal * (1 + rate)^years
Total = 3,400 * (1.022)^.25
