Answer:
0.875
Step-by-step explanation:
7/8 as a decimal is 0.875. Another was of thinking of this is the number '7' is 87.5 percent of the number '8.
Find the slope of the line connecting (1990,435000) and (2005,482300):
482300-435000 47300
m = ----------------------- = ---------------- = 3153/yr (approx)
2005 - 1990 15 yr
Use the point-slope formula to find the equation of this str. line:
y-435000 = (3153/yr)(x-1990)
The year 2020 is 30 years after 1990. Thus, the expected pop in 2020 is
given by y-435000 = 3153(30) = 94590, so that y = 529590.
Answer:
see explanation
Step-by-step explanation:
These are the terms of a geometric sequence with n th term
= a
Where a is the first term and r the common ratio
r =
=
=
= 2
and a = 5, hence explicit equation is
= 5
