With what is a similarity transformation? what is necessary to determine whether two or more shapes are similar? explain in terms of rigid transformations, dilations, proportionality, and scale factors.

Similarity transformations include dilation and any number of rigid transformations. In a similarity transformation, the ratio of the lengths of corresponding sides in the image and the preimage is equal to the scale factor of dilation. Two or more similar figures will have corresponding sides that are proportional in length.

Step-by-step explanation:

plato

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %

they would have to work 32 hours.
