Area of the triangle: 1/2 x 6 x 8 = 24 square ft.
Area of half circle: 1/2 x 3.14 x 4^2 = 25.12 square feet.
Total area : 24 + 25.12 = 49.12 square feet.
A is the correct answer
Or
Vertex = (-5,-4), y-intercept = (0,21), x-intercepts = (-7,0) and (-3,0), axis of
symmetry is x = -5
Answer: 
Step-by-step explanation:
The confidence interval for population mean is given by :-

, where
= Population standard deviation.
n= sample size
= Sample mean
z* = Critical z-value .
Given :
n= 49
Two-tailed critical value for 95% confidence interval = 
Then, the 95% confidence interval would be :-




Hence, the 95% confidence interval for estimating the population mean
:

Answer:
5 g
