radians = degrees x PI/180
radians = 60 x pi/180 = 1.04719 radians
round answer as needed
if you need it in terms of pi it would be PI/3 radians
Answer:
Step-by-step explanation:
To solve this problem, we can use the area of a circle formula as shown below:
<em>A = area</em>
<em>r = radius</em>
<em />
First we need to find the radius.
The radius is half of the diameter. For this problem, the radius is going to be 3.
Now, plug the values into the equation:
The window's area is
Answer:
Step-by-step explanation:
Given that a poll showed the approval rating to be 0.45 (45 %)
Second poll n =2500: sample p = 1185/2500 = 0.474
H0: p = 0.45
Ha: p not equals 0.45
(Two tailed test)
p difference = 0.024
z-statistic 0.179
Significance level P = 0.8577
95% CI of observed proportion 0.24% to 0.83%
Since p>0.05 we accept null hypothesis
The results of the second poll do not indicate that the proportion of voters who approve of the job the president is doing is significantly higher than the original level
The answer should be a decrease cause the more soda they drink the less water they will want to drink
