N = number of seeds planted

P = probability of germination

K = number that germinated

Using probability calculation:
p(x = k) = (n k) x 0.90^K x 0.10^n-k

p(10) = (12 10) x 0.90^10 x 0.10^2

P(10) = 0.2310

A new shopping mall records 150 total shoppers on their first day of business. Each day after that, the number of shoppers is 15

Wewaii [24]

The number of shoppers is an illustration of an exponential function.

The expression for the number of shoppers is: $\mathbf{f(n) = 150(1.15)^n}$

The given parameters are:

$\mathbf{a = 150}$ -- the number of shoppers on the first day of business

$\mathbf{r = 15\%}$ --- the rate

Because, the number of shoppers increases each day, the number of shopper on a certain day is:

$\mathbf{f(n) = a \times (1 + r)^n}$

Substitute 15% for r

$\mathbf{f(n) = a \times (1 + 15\%)^n}$

Express percentage as decimal

$\mathbf{f(n) = a \times (1 + 0.15)^n}$

$\mathbf{f(n) = a \times (1.15)^n}$

Substitute 150 for a

$\mathbf{f(n) = 150 \times (1.15)^n}$

$\mathbf{f(n) = 150(1.15)^n}$

Hence, the expression for the number of shoppers is: $\mathbf{f(n) = 150(1.15)^n}$
