Answer:
There are 548.64 cm in 18 feet.
Step-by-step explanation:
We know that, 1 inch = 2.54 centimeters.
We need to convert 18 feet to centimeters
Also, 1 foot = 12 inch
Firstly we will convert 18 feet to inch.
18 feet = 12 × 18 inch
= 216 inch
Now to convert 18 feet to centimeters, multiply 216 inch by 2.54 cm as follows :
216 inch = 2.54×216 centimeters
= 548.64 cm
Hence, there are 548.64 cm in 18 feet.
Coefficient of variation is calculated by dividing the standard deviation by the mean multiplied by 100. Given a data set with mean equal to 60 and variance equal to 9, we can calculate the coefficient of variation by finding the value of the standard deviation which is the square root of the variance. so standard deviation is equal to square root of 9 which is 3. Then, the coefficient of variation is equal to 3/60*100 which is equal to 5%.
x= A ticket
y=b ticket
x+y=500
10x+60y=6000
-------------------
10x+60y=6000
- x+y=500 (*10) ---> 10x+10y=5000
-------------------
10x+60y=6000
- 10x+10y=5000
-------------------
50y=1000
y=1000/50
y=20
b ticket =20
x+y=500
x+20=500
x=500-20
x=480
a ticket=480
answer is the last option ,
