24|5
25|0, 1, 3, 8
26|4, 7, 9
27|3, 6
key in bottom right
24|5 means 245
Simple, change 25% into 0.25.
Thus,
n=0.25*200
n=50
thus, your answer is, 25% of 200 is 50.
Answer:
120°, 150°
Step-by-step explanation:
the first polygon has 6 sides, and has an interior angle sum of 720°. you then divide that by 6 to get a single angle. The second polygon has 12 sides and a total of 1800°, which is then divided by 12 to get the single angle.
Answer:
"A Type I error in the context of this problem is to conclude that the true mean wind speed at the site is higher than 15 mph when it actually is not higher than 15 mph."
Step-by-step explanation:
A Type I error happens when a true null hypothesis is rejected.
In this case, as the claim that want to be tested is that the average wind speed is significantly higher than 15 mph, the null hypothesis has to state the opposite: the average wind speed is equal or less than 15 mph.
Then, with this null hypothesis, the Type I error implies a rejection of the hypothesis that the average wind speed is equal or less than 15 mph. This is equivalent to say that there is evidence that the average speed is significantly higher than 15 mph.
"A Type I error in the context of this problem is to conclude that the true mean wind speed at the site is higher than 15 mph when it actually is not higher than 15 mph."
