The faculty senate at a large university wanted to know what proportion of the students thought foreign language classes should be required for everyone. The statistics department offered to cooperate in conducting a survey, and a simple random sample of 500 students was selected from all the students enrolled in statistics classes. A survey form was sent by email to these 500 students. In this case, the population of interest is:(a) all the students at the university.(b) all the students enrolled in a statistics class.(c) the 500 students who got the email survey.(d) the students who responded to the email survey.(e) all the students who think that foreign language classes should be required for everyone. In this case, the sampling frame is:(a) all the students at the university.(b) all the students enrolled in a statistics class.(c) the 500 students who got the email survey.(d) the students who responded to the email survey.(e) all the students who think that foreign language classes should be required for everyone. Which of the following is true about this study?(a) Since the sample is random, it is representative of the population of interest.(b) Even though the sample is random, it is not representative of the population of interest.

konichiwa~! my name is zalgo and i am here to answer your anime-related question today. more than likely, kirishima would kill izuku, marry mino and kiss momo. all of this would be my opinion by the way. (and i am also a weeb lol)

i hope this you! : d

(and do you think you can mark me as brainliest? i'd greatly appreciate it! arigato~! )

i think it is 70

step-by-step explanation:

1/800 is the right answer

1. when "a" is a root of a polynomial, (x -a) is a factor of it. for the three roots given, the factors of the desired polynomial are (x +2)(x -1/2)(x -3).

in order to make the leading coefficient be negative, we need to multiply this product by a negative number. any negative number will do, but we choose a small (magnitude) value that will eliminate the fraction: -2.

then

f(x) = -2(x +2)(x -1/2)(x -3) = -(x +2)(2x -1)(x -3)

= -(2x² +3x -2)(x -3)

= -(2x³ -3x² -11x +6)

f(x) = -2x³ +3x² +11x -6

2. a graph created by the desmos on-line graphing calculator is shown, and the zeros are highlighted.

3. as indicated in part 1, the multiplier of this equation can be anything and the zeros will remain the same. you want a negative leading coefficient, so the "anything" is restricted to any of the infinite number of numbers that will make that be the case.
