The probability that the aircraft is overloaded is 0.6141; since this is a greater than 50% chance, the pilot should either reduce the number of passengers on the plane or require them to reduce their baggage.
The z-score for this is given by
z = (X-μ)/σ = (169-180.2)/38 = -11.2/38 = -0.29.
Using a z-table (http://www.z-table.com) we see that the probability of weights being less than this (the area to the left of this score) is 0.3859; to find the probability that the weight is greater than this (to the right), we subtract from 1:
1-0.3859 = 0.6141.
Answer:
<u>The original price of the coat was £ 275</u>
Step-by-step explanation:
1. Let's review all the information given for solving this question:
Sale price of the coat = £ 220
Discount from the original price = 20%
2. Let's find the original price of the coat
Original price of the coat = x
Sale price of the coat = £ 220
Sale price of the coat = x - 20%x
220 = x - 0.2x
220 = x - 2x/10 (0.2 = 2/10)
2,200 = 10x -2x (Multiplying by 10 at both sides)
2,200 = 8x
2.200/8 = 8x/8 (Dividing by 8 at both sides)
275 = x
<u>The original price of the coat was £ 275</u>

Answer:
(-2,1)
Step-by-step explanation:
So we are given f(-3)=1 since the point (-3,1) is on f(x).
We want to use this point to find a point on f(x-1).
Now,
f(-3)=1
and we want
f(x-1)=1
What would x need to be such that x-1 is -3.
x-1=-3
Add 1 on both sides:
x=-3+1
x=-2
x would need to be -2 in f(x-1)=1 in order to use that f(-3)=1.
So (-2,1) is the point for the function f(x-1) that corresponds to the point (-3,1) for f(x).
I know that f(x-1) would only be effecting our input because x-1 is the input.
