Suppose that an airline uses a seat width of 16.7 in. Assume men have hip breadths that are normally distributed with a mean of
murzikaleks [220]

Answer:

Step-by-step explanation:

Given that X, the hip width of men is N(14.2, 0.9)

i.e. we have \frac{x-14.2}{0.9} is N(0,1)

Seat width an airline uses = 16.7 inches.

a) the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.7 in

=P(X>16.7 inches)\\= P(Z>\frac{16.7-14.2}{0.9} =P(Z>2.77)\\\\\\=P(Z>0)-(0

b) Here sample size = 126

Each person is independent of the other

the probability that these men have a mean hip breadth greater than 16.7

=0.0028^{126} <0.00001

c) part a is important since even a single person not fitting will cause embarassment and leads to customer dissatisfaction.

At the beginning of the season, MacDonald had to remove 555 orange trees from his farm. Each of the remaining trees produced 210
nevsk [136]

Answer:

Initial number of trees were 204.

Step-by-step explanation:

555 must be a typo error. The question will not produce correct answer. I worked out with 55 but the answer is wrong. So, the number is 5.

Lets say MacDonald removed 5 orange trees from his farm.

Let t be the initial number of trees

After removing 5 trees, the remaining left are t-5 trees

As given - Each of the remaining trees produced 210 oranges for a total harvest of 41790 oranges. This means

(t-5)210= 41790

Solving for t:

210t-1050=41790

210t=41790+1050

210t=42840

t = 204

So, initial number of trees were 204.

We can check this : 204-5=199

199\times210=41790

------------------------------------------------------------------------------------------

Working with 55 we get the wrong answer:

(t-55)210=41790

210t-11550=41790

210t=30240

t = 144

We can check this : 144-5=139

139\times210=29190  (wrong)
