Assume there are n students in the class. Each student is assigned a seat labeled from 1 to n. The students walk into the classroom according to their seat numbers, i. e., the student assigned seat 1 walks in first and n last. If a student finds the seat assigned to him is occupied, he will select a seat from currently empty seats uniformly at random. If the first student forgets his seat number, which means the student will select a seat from all empty seats uniformly at random, what is the probability that the nth student still sits in his seat?

55/i dont know i do it for the points

step-by-step explanation:

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

the answer is 128

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
