Answer:
Step-by-step explanation:
Given
The attached table
Required
Determine the equation of the table
The table represents an exponential function. So, we make use of
When x = 0, y= 5.
So:
becomes
When x = 1; y = 15
So;
becomes
Substitute 5 for a
Divide both sides by 5
Substitute values for a and b in:
Answer:
C
Step-by-step explanation:
Find P(X > 67)
using ( x - mean )/ standard deviation again you will get thi(1) which is equal to 0.8413....
0.8413 x 5000 is 4207
A larger interval is wider than a smaller interval.
The correct equation is P(t) = Po*e^(kt). Please enclose "kt" inside parentheses and use the " ^ " symbol to indicate exponentiation.
"k" is the growth constant, which here is 0.017. "t" is the number of yeasrs. P(7) is the population after 7 years. Po is the initial population, which in this case is 91 million.
The initial value, when t = 0, is 91 million.
After 7 years, the population, P(7), was P(7) = (91 million)*e^(0.017*7). This evaluates to P(7) = (91 million)*(1.070) = 96 million
