Danny wants to test to see if the mean age (years) of current UCF students is less than 500. He sampled 300 current UCF students and found a sample mean of 20.3. Assume the standard deviation is 2. Based on this information, at the 1% significance level, which is the best conclusion

he can buy 4lbs. of live bait and 1lbs of natural bait

step-by-step explanation:

- (2, -7)

- lines r and s and lines t and u must be parallel

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
