The answer is 0.5! Good luck
Data is collected on the types of vehicles
this is cross sectional data
Time is not relavant for this data and hence cannot be time series data.
b)
from the given information, the variable is type of vehicle which is categorical data
c)
this data is only about the more frequent vehicles the chain cannot ignore the vehicles which are not parked
Answer:
# of 20cent stamps = 8
Step-by-step explanation:
Let the number 20cent stamps be = x
Let the number 60 cents stamps be = y
Total number of stamps => 20 = x + y ----------- ( 1 )
Total cost of the stamps = 8.80
That is, 0.20x + 0.60y = 8.80 ------------- ( 2 )
( 2 ) => 20x + 60y = 880
=> x + 3y = 44
=> x = 44 - 3y
Substitute x in ( 1 ) => x + y = 20
44 - 3y + y = 20
- 2y = 20 - 44
- 2y = - 24
2y = 24
y = 12
Substitute y = 12 in ( 1 ) => x + y = 20
x + 12 = 20
x = 8
The length would be 9.
Area of a square is side^2, so to solve for side, take the square root of 81
Answer:10
Step-by-step explanation:
Each exterior angle is (3x + 6)°
A decagon has 10 sides
Each exterior angle=360/n
n=number of sides
3x+6=360/10
Cross multiply
10(3x + 6)=360
30x+60=360
Collect like terms
30x=360-60
30x=300
Divide both sides by 30
30x/30=300/30
x=10
