Answer:
The result is significant.
Step-by-step explanation:
Here,
p = 30 ÷ 330 = 0.091
thus, q = 1 - p = 0.909
Also, 
⇒ 
The z-score is:
Thus, at 95% confidence interval, p-value = 0.005
The result is significant at p < .05.
Answer:
B.
D.
E.
Step-by-step explanation:
Tax = rate * purchase price
tax = 0.07 * 50
tax = $3.50
Make a line down the other side of the E so it becomes a rectangle, find the area of the big rectangle (12•10=120 inches) then find the smaller rectangles (7•5=35 inches) since there’s two small rectangles w the same measurements the area is the same(35+35= 70 inches) , Now u wanna subtract the area of the two small rectangles ( 70-120=50 inches) the Area of the E is 50 inches
Hope I explain it okay and it helps you!
Answer:
658.24 m
Step-by-step explanation:
The figure makes a triangle with vertices abc.
Where ab = 500 m
bc = 350 m
The angle abc = 100°
Using the cosine rule we can find the distance ac.
ac² = 500²+350² - 2×500×350×cos100°
= 372,500 - -60,776.86
= 433,276.86
ac = √433,276.86
= 658.24 m
