Answer:
y=0.8x+2.1
x= 12 miles
Step-by-step explanation:
Using the standard charge of 0.8 per mile and a fixed charge of $2.1. Let x represent the miles covered then the expression for coat at any given mile will be y=0.8x+2.1
Substituting $11.7 for y then we can find the valje of x as 11.7=0.8x+2.1
0.8x=11.7-2.1=9.6
X=9.6/0.8=12 miles

Answer:
31/40
Step-by-step explanation:
Probability is given by number of possible outcomes ÷ number of total outcomes
Number of possible outcomes = 270, number of total outcomes = 1200
Probability (the number of people from the suburbs attending the concert is 270) = 270/1200 = 9/40
Probability (the number of people from the suburbs attending the concert is fewer than 270) means that the number of people from the suburbs attending the concert is not 270 = 1 - 9/40 = (40-9)/9 = 31/40
Answer:
0.142 cm/yr
Step-by-step explanation:
An <em>average</em> is the sum of all the measurements divided by the number of measurements.
If there was a measurement each year, there were 175 measurements, and their sum is 24.8 cm.
Average movement = 24.8/175
Average movement = 0.142 cm/yr
The land moved an average of 0.121 cm each year
