Answer:
85.99% of airline passengers incur this fee.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean 
and standard deviation 
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Mean 46 pounds and standard deviation 3.7 pounds.
This means that 
Most airlines charge a fee for baggage that weigh in excess of 50 pounds. Determine what percent of airline passengers incur this fee.
As a proportion, this is 1 subtracted by the pvalue of Z when X = 50. So
has a pvalue of 0.8599
0.8599*100% = 85.99%
85.99% of airline passengers incur this fee.
Answer:
x=-8
y=4
Step-by-step explanation:
first you multiply this equation (-3x-2y=16) with negativ it will be like this 3x+2y=-16
3x+2y=-16
(x+9y=28)3 _multiply with 3
3x+2y=-16
3x+27y=84
use minus(-) =3x-3x=0
=2y-27y=-25y
=-16-84=-100
the result:-25y=-100
y=4
take any simple equation and replace y with 4
x+9y=28
x+9(4)=28
x+36=28
x=28-36
x=-8
answer:x=-8,y=4
The answer is 2/5 < 1/2
Because if you do common denominator which is 10 you get 2/5 as 4/10 and 1/2 as 5/10 so therefore 1/2 is greater
Answer:
27 =x
Step-by-step explanation:
We can use proportions to solve this problem. Put the side of the small triangle over the same side of the large triangle.
x+8 10
------- = -------------------
2x-5 14
Using cross products
14 (x+8) = 10 (2x-5)
Distribute
14x+112 = 20x-50
Subtract 14x from each side
14x-14x +112 = 20x-50-14x
112 = 6x-50
Add 50 to each side
112+50 = 6x-50+50
162 = 6x
Divide by 6
162/6 =6x/6
27 =x
