Answer:
Step-by-step explanation:
731² - 631² is the difference of squares.
731² - 631² = (731+631)(731-631) = 1362×100
therefore, 731² - 631² is divisible by 100
The answer to this question is 50 because you have to multiply 100x50 and you get 5000
Answer:
One sample test of proportions
Step-by-step explanation:
Which test is most appropriate to test whether the proportion of skiers is not 0.50?
Since the test says to test whether the proportion of skiers is not 0.50, then here we will be studying just only the promotion of skiers without the comparison with snowboarders.
We have been given an hypothesized promotion and the test says to test against this proportion, so the appropriate test to use here is the one sample test of proportions
First do 17 - 1 to get 16. Then subtract 0.2 from 16.0 to get 15.8.
Could you give some information? The table would be really good, I’d be able to help you more efficiently. ☺️
