Triangle KLM was dilated according to the rule

Answer:
Correct choices are A, B and D
Step-by-step explanation:
The rule DO,0.75 (x,y) is a dilation by a scale factor of 0.75 about the origin. This rule can be rewritten as
(x,y)→(0.75x,0.75y) (option A is true).
The dilation preserves parallel lines, then LM is parallel to L'M' (option B is true).
According to the rule of dilation, this means that K'M' is shorter than KM (option C is false).
The vertices of the image are placed on the segments that connect origin with vertices of the pre-image triangle, then the vertices of the image are closer to the origin than those of the pre-image (option D is true).
The distance from M' to the origin is exactly 0.75 times the distance from M to the origin (option E is false).

Answer:
The binomial probability formula can not be used for this experiment because it does not state the number of times he expects to draw his favorite suit.
Step-by-step explanation:
The binomial probability formula is expressed as follows:
P (k success in n trials) =
n = number of trials, k = number of successes, n-k = number of failures, p = probability of success in one trial and q = 1 - p = probability of failure in one trial.
In the given problem, all of the variables are known except for 'k', the amount of times that the student predicts he will draw his favorite suit.
