There are 180 students in a school band attending an awards dinner. A random survey of 20 band students was conducted to determine how many of each meal
should be prepared for the dinner. The results of the survey are shown.

•11 students selected Cajun pasta
•4 students selected Chicken pasta
•5 students selected Shrimp pasta

Based on the survey results, which of these is the best prediction of the
meals wanted by the 180 students?

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 think the correct option is the second option.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
