Answer:
The scale is not reasonable .
Step-by-step explanation:
We are given that Sarah is making a scale drawing of a painting that is 48 in. wide by 120 in. high.
Her paper is 12 in. wide and 24 in. tall.
Scale : 1 in. = 4 in.
Since 1 inch = 4 inch
So, 12 inch =
24 inch =
The given scale is not reasonable because the scale is true for the width but false for the height
Since the actual height is 120 inches and we are getting 96 inches using the given scale .
Hence the scale is not reasonable .

I would be surprised because the value is very small , less the 0.05
Step-by-step explanation:
From the question we are told that
The probability a randomly selected individual will not cover his or her mouth when sneezing is
Generally data collected from this study follows binomial distribution because the number of trials is finite , there are only two outcomes, (covering , and not covering mouth when sneezing ) , the trial are independent
Hence for a randomly selected variable X we have that
The probability distribution function for binomial distribution is
Considering question a
Generally the the probability that among 12 randomly observed individuals exactly 8 do not cover their mouth when sneezing is mathematically represented as
Here C denotes combination
So
Considering question b
Generally the probability that among 12 randomly observed individuals fewer than 5 do not cover their mouth when sneezing is mathematically represented as
=>
=>
=>
Considering question c
Generally the probability that fewer than half(6) covered their mouth when sneezing(i.e the probability the greater than half do not cover their mouth when sneezing) is mathematically represented as
=>
