Asurvey showed that 72% of adults need correction (eyeglasses, contacts, surgery, etc.) for their eyesight. if 18 adults are randomly selected, find the probability that no more than 1 of them need correction for their eyesight. is 1 a significantly low number of adults requiring eyesight correction?

Step-by-step explanation:

Given that a  survey showed that 72​% of adults need correction​ (eyeglasses, contacts,​ surgery, etc.) for their eyesight

X - number of people who need correction for their eyesight

X is binomial since each event is independent and there are only two outcmes.

X (18, 0.72)

Required probability = the probability that no more than 1 of them need correction for their eyesight.

=P(X=0)+P(X=1)=0.00000296+0.000137

=0.00014

Yes 1 is a significantly low number as probability is almost zero.

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

answer: h
