Acomposition of transformations maps ∆klm to ∆k"l"m". the first transformation for this composition is and the second transformation is a translation down and to the right

a. a 90° rotation about point l
b. a 270° rotation about point l
c. a 90° rotation about point p
d. a 270° rotation about point p

Option D.

Step-by-step explanation:

Since MK and M'K' are at 90° after transformation which means MK is rotated either 90° clockwise about P or 270° counterclockwise about P.

So the composition of transformations which maps ΔKLM to ΔK"L"M", the first transformation for this composition is rotation of 270° counterclockwise about the point P.

And the second transformation is a translation down and to the right.

"Option D. a 270° rotation about point P" is the answer.

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.

answer: 1+1

step-by-step explanation: 1+1 is at least 2
