As a simplified model for weather forecasting, suppose that the weather (either wet or dry) tomorrow will be the same as the weather today with probability p. show that the weather is dry on january 1, then

pn

, the probability that it will be dry n days layer, satisfies

pn=(2p−1)pn−1+(1−p)n≥1

p0=1

prove that

pn=1/2+1/2(2p−1)nn≥0

answer: 177/8

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
