have a great day!
Answer:
Step-by-step explanation:
Given that
sample size n = 55: x bar = 654.16 and s = sample sd = 162.34
Std error = 162.34/sqrt 55 = 21.889
For 95% CI we can use t critical value as population std dev is not known.
df = 54
t critical = 2.004
Margin of error = 2.004 *21.889 = 43.866
Confidence interval lower bound = 654.16-43.866 =610.294
Upper bound = 654.16+43.866=698.026
Confidence interval rounded off at 95% = (610.29, 698.23)
The answer is 13.8h-2.3hk
What is the question more information
Answer:
174 feet squared
Step-by-step explanation:
The figure is composed of a rectangle and a right triangle
Therefore,
Area of the composite figure = area of the rectangle + area of the right triangle
= (L*W) + (½*b*h)
L = 18 ft
W = 9 ft
b = 18 - (6 + 6) = 6 ft
h = 4 ft
Plug in the values into the equation
Area of the composite figure = (18*9) + (½*6*4)
= 162 + 12
= 174 ft²
