A population of 240 birds increases at a rate of 16% annually. Jemel writes an exponential function of the form f(x) = abx to re

d1i1m1o1n [39]

An exponential function is :
f ( x ) = a * b^x,
where x is the number of the years.
a = 240 ( number of the birds at start )
16 % = 0.16
b = 1 + 0.16 = 1.16
f ( x ) = 240 * 1.16^x
Answer:
a = 240, b = 1.16

Incomplete Question (See Complete Question Below)

A bag contains 10 red marbles and 15 green marbles.If Yuki selects a marble from the bag without looking, what is the probability that she will pull a red marble?

A-1/5

B-2/5

C-1/2

Answer:

The probability of pulling a red marble is $\frac{2}{5}$

Step-by-step explanation:

Given

Red Marble = 10

Green Marble = 15

Required

The probability of picking a red marble

First, the total number of marble has to be calculated

Total = Red Marble + Green Marble

Total = 10 marbles + 15 marbles

Total = 25 marbles

The probability of an event is often calculated by dividing the number of required outcomes by the number of possible outcomes.

In this case, the probability of pulling a red marble is calculated as follows:

$P(R) = \frac{n(R)}{T}$

Where P(R) represents probability of pulling a red marble

n(R) represents number of red marbles

n(R) = 10

T represents total number of marbles

T = 25

By substitution,

$P(R) = \frac{n(R)}{T}$ becomes

$P(R) = \frac{10}{25}$

Reduce fraction to lowest term by dividing the numerator and denominator by 5

$P(R) = \frac{2}{5}$

Hence, the probability of pulling a red marble is $\frac{2}{5}$
