A. Use what you've learned in this unit to model the population of Western

Leona [35]

An exponential function can either represent population growth or population decay

<h3>How to model the population</h3>

The question is incomplete, as the resources to model the population of the Western Lowland Gorillas are not given.

However, the following is a general guide to solve the question.

An exponential function is represented as:

$y=a(1 \pm r)^x$

Where:

(a) represent the initial value i.e. the initial population of the Western Lowland Gorillas
(r) represents the rate at which the population increases or decreases.
(x) represents the number of years since 2022
(y) represents the population in x years

Given that the population of the Western Lowland Gorillas decreases, then the rate of the function would be 1 -r (i.e. an exponential decay)

Take for instance:

$y = 20000 * 0.98^x$

By comparison.

a = 2000 and 1 - r = 0.98

The above function can be used to model the population of the Western Lowland Gorillas

On the graph of f(x)=cos x and the interval [0,2π), for what value of x does f(x) achieve a minimum?

Mariulka [41]

Answer:

$cos(\pi)=-1$

Step-by-step explanation:

$f(x)=cos (x)$

State that the values where cos x is minimum:

$x=\pi +2\pi n, n\in \mathbb{Z}$

$cos(0)=1\\$

$cos\left(\frac{\pi}{4} \right)=\frac{\sqrt{2} }{2}$

$cos\left(\frac{\pi}{2} \right)=0$

$cos(\pi)=-1$

$cos\left(\frac{3\pi}{2} \right)=0$

According to records from 50 years, there is a 2/3 chance of June temperatures being above 80 F. Azul needs to find the probabil

Brrunno [24]

Record of june temperature of last 50 years

Probability of June temperature being above 80° F from last 50 years

$=\frac{2}{3}$

It means , out of 30 days ,there are only 20 days , in which temperature is above 80°F.

⇒Probability that it will be above 80° F for 20 or more days this June

$=\frac{20+x}{30}$

where, x is the number of extra days after 20 days in month of june, when temperature is above 80°F.

Value of this Probability will be in between

$\frac{2}{3}\leq P \leq 1$

Now, what Azul wants

To find the probability that it will be above 80° F for 20 or more days this June.

The Simulation given is

⇒There are 30 days in June. If we use a number cube with the numbers 1-6 and assign 1-4 as a temperature above 80° F and 5-6 as a temperature 80° F or below.

Total number of numbers on number cube ={1,2,3,4,5,6}

Favorable Outcome={1,2,3,4}=Temperature above 80° F

Temperature 80° F or below ={5,6}

⇒Probability of getting number {1,2,3,4} on the number cube when rolled once,that is Temperature above 80° F

$=\frac{4}{6}\\\\=\frac{2}{3}$

⇒Probability of getting number {5,6} on the number cube when rolled once, that is Temperature 80° F or below

$=\frac{2}{6}\\\\=\frac{1}{3}$

This is Incorrect Simulation, as there are chances that , there can be more than 20 days out of 30 days when Temperature goes above 80° F.But Here we have got Probability of temperature being above 80° F for 20 days only, not more than 20 days, which is $=\frac{2}{3}$

Not,a number

$\frac{2}{3}< \text{Probability} \leq 1$ .
