If the upper quartile of the given data is 70 km/hr., find the value of p. Speed in km/hr. 0-20 20-40 40-60 60-80 80-100

No. of vehicles 12 3 11 p 6​

i would need to see the dot plot : )

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

i would say b) is your answer

sorry if im wrong
