On the top problem: Angle A and Angle B are a right angle so it equals 90 degrees. If Angle B is 50 degrees that makes Angle A 40 degrees. Angle A and Angle C is a straight line and equals 180 degrees so if Angle A equals 40 degrees that means Angle C equals 140 degrees.
Answer:
a) Standard error = 0.5
b) 99% Confidence interval: (19.2125,21.7875)
Step-by-step explanation:
We are given the following in the question:
Population mean = 20.50 mpg
Sample standard deviation = 3.00 mpg
Sample size , n = 36
Standard Error =
99% Confidence interval:
Putting the values, we get,
Answer:
140%
Step-by-step explanation:
28-10 = 14 person enrolled
14/10 = 140%
For the first 6, we see that it is exactly one place behind the decimal point, therefore meaning that it is in the tenths place. The second 6 is three places behind the decimal place making it in the thousandths place. The third and final 6 is one place in front of the decimal, therefore it is in the ones place. Hope this helps!
