Answer:
290.6 backpacks per year
Step-by-step explanation:
The average of 5 numbers is 1/5 of their sum:
average = (278 +310 +320 +242 +303)/5 = 290.6
The average number of backpacks given out in the last 5 years is 290.6, about 291.
Angle 1 and 2 are both equal so you would do 4x+2=3x+9
and the answer would be x=7
Answer:
The population of city is 7 million in 2015.
Step-by-step explanation:
It is given that the population of a city, P, in millions, is a function of t, the number of years since 2010.
It means, P = f(t).
We need to explain the meaning of the statement f(5) = 7 in terms of the population of this city.
f(5) = 7 means the population is 7 millions at t=5.
t = 5 means 5 years after 2010, i.e., 2010+5 = 2015
Therefore, the population of city is 7 million in 2015.
