A researcher wishes to find out if the published max speed of a 737 jet is accurate, but needs to know how many jets to include in the sample. From past studies it is.
known that the population standard deviation of speeds is 68 mph.
(a) Assuming that she would like to be 90% confident of the results, indicate the
critical value that corresponds to this given level of confidence. Round to two
decimals and remember that critical values are defined to be positive.
(b) If she would like to have a maximum error of 15 mph, how many jets should be
sampled?

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)

welll its a very hard question but ill

step-by-step explanation:

first you take the 6 dollars and add 10 to it then add the 50 to that then multiply by 8 with xy and your answer will be

hope this

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
