Hello!
To solve this we use the equation sin60 = (s/2) / (d/2)
s is a side of the triangle
d is the diameter
sin60 = s/d
put 6 in for s
d = 6.9
The answer is C) 6.9
Hope this helps!
Answer:
105 sq cm
Step-by-step explanation:
The bottom rectangle is 6 x 15 = 90 sq cm
The triangle at the top has a length of 15 - 9 = 6 cm and a height of 11 - 6 = 5 cm.
A triangle is 1/2bh so 1/2 x 6 x 5 = 15 sq cm
Add the areas together
Answer:
law of contrapositive
Step-by-step explanation:
Answer:
The 95% confidence interval for the overall noncompliance proportion is (0.0387, 0.1169).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
For this problem, we have that:
95% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The 95% confidence interval for the overall noncompliance proportion is (0.0387, 0.1169).
