Alejandro surveyed his classmates to determine who has ever gone surfing and who has ever gone snowboarding. Let A be the event that the person has gone surfing, and let B be the event that the person has gone snowboarding. Which statement is true about whether A and B are independent events? A and B are independent events because P(A∣B) = P(A) = 0.16. A and B are independent events because P(A∣B) = P(A) = 0.75. A and B are not independent events because P(A∣B) = 0.16 and P(A) = 0.75. A and B are not independent events because P(A∣B) = 0.75 and P(A) = 0.16.

First of all we need to know when does two events become independent:

For the two events to be independent,  that is if condition on one does not effect the probability of other event.

Here, in our case the only option that satisfies the condition for the events to be independent is . Rest are not in accordance with the definition of independent events.

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

answer: the center is the median and/or mean of the data. the spread is the range of the data. and, the shape describes the type of graph. the four ways to describe shape are whether it is symmetric, how many peaks it has, if it is skewed to the left or right, and whether it is uniform. good luck
