The taxi and takeoff time for commercial jets is a random variable x with a mean of 8.2 minutes and a standard deviation of 3.4 minut normal. You may assume that the jets are lined up on a runway so that one taxies and takes off immediately after the other, and that t in USE SALT (a) What is the probability that for 35 jets on a given runway, total taxi and takeoff time will be less than 320 minutes? (Round x 0 (b) What is the probability that for 35 jets on a given runway, total taxi and takeoff time will be more than 275 minutes? (Rounc (C) What is the probability that for 35 jets on a given runway, total taxi and takeoff time will be between 275 and 320 minutes?

step-by-step explanation:

the correct answer is the second option

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
