If one ratio is equivalent to another, that means that you multiply the top and the bottom on one ratio by a constant to get the larger ratio. D does that here for us. We have to multiply 3 by 5 to get to 15, so 16 times 5 better be 80 and it is.
The answer is 13 because,of both sides are parallel and the other sides opposite is half the there fore half of 26 is 13
Answer:
Thus difference in sample proportions would be the unbiased estimate of the difference between the two proportions
Step-by-step explanation:
Given that you construct a confidence interval for the difference between two proportions
Let the proportions be p1 and p2
Sample sizes be n1 and n2
For samples of larger size randomly drawn we know that
p1 follows Normal with mean = sample proportion = p1 and
p2 is N with mean = sample proportion p2
Assuming these two proportions are independent we have
p1-p2 will follow a normal distribution with mean = p1-p2
Thus difference in sample proportions would be the unbiased estimate of the difference between the two proportions
Answer: 270 miles
Step-by-step explanation:
From the question, we are informed that the scale for a map to actual distance is 2 cm to 100 mi and that the driving distance on the map between Los Angeles and Las Vegas is 5.4 cm.
The actual distance, in miles, between Los Angeles and Las Vegas will go thus:
= 5.4cm/2cm × 100mi
= 2.7cm × 100miles
= 270 miles
