Answer:

$9.33

Exponential growth.

Step-by-step explanation:

The formula for an exponential function is:

abˣ = y OR

a(1 + r)ˣ = y

a is the initial value (4.22)

r is the rate of increase (3.1% or 0.031 in dec. form) where 1 + r is b

x is the time (26 years)

y is the ending value.

If we plug those values in, the equation will turn out to be 4.22(1 + 0.031)²⁶ = y

Plug it into a calculator and you will get 9.333354216

This is exponential growth because x, the initial value, increases to get to y, the ending value.

Suppose that 75 percent of the people in a certain metropolitan area live in the city and 25 percent in the suburbs. If 1200 peo
juin [17]

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
