The exponential model A=302.5e^0.0211 describes the​ population, A, of a country in​ millions, t years after 2003. Use the model
Naddik [55]

The population of the country in 2003 is 302.5 million

<h3>How to determine the population of the country in 2003.</h3>

From the question, we have the following parameters that can be used in our computation:

Exponential model, A = 302.5e^0.0211t

Where i is the number of years after 2003

In the year 2003, the value of t is 0

i.e. 0 years after 2003

So, we have

A = 302.5e^(0.0211 * 0)

Evaluate the products

A = 302.5 * 1

So, we have the following result

A = 302.5

Hence, the population is 302.5 million

What is the absolute davatation round to the nearest tenth for 6.3, 6.4, 6.5, 6.6, 6.8. 6.8, 7.5?
WITCHER [35]
Let's find the mean of all the values first.
6.3+6.4+6.5+6.6+6.8+6.8+7.5= 46.9
Let's divide by the number of values.
46.9÷7=
6.7
Now let's find the distance that each number is away from 6.7 and find the mean of those numbers.
0.4+0.3+0.2+0.1+0.1+0.1+0.8=
.2857
≈ 0.3
So, the absolute deviation is 0.3.

If 100 people drink 1.5 cups of coffee a day and the cost per cup is .40 how much would it cost to provide coffee for the whole
N76 [4]

Answer:

It would cost <u>15600</u> to provide coffee for the whole year.

Step-by-step explanation:

Given:

If 100 people drink 1.5 cups of coffee a day and the cost per cup is .40

Now, to find the cost to provide coffee for the whole year if you're place is open 5 days a week.

So, we have the unit rate, and we have to find the cost of 1.5 cup by multiplying 0.40.

<em>1.5 cup of coffee cost </em>1.5\times 0.40=0.60.

<em>Thus, 1.5 cup cost 0.60.</em>

<em>If, 100 people drink 1.5 cups. </em>

<em>Then, total cost of  100 people drinking 1.5 cups of coffee = </em>100\times 0.60=60<em />

<em>As, place is open 5 days a week.</em>

So, to get the cost of coffee in 5 days of a week we multiply 5 by 60:

5\times 60\\\\=300.

<em>Hence, the cost of coffee in a week is 300.</em>

<em>In 1 year there are 52 weeks.</em>

Now, to get the cost for the whole year we multiply 52 by 300:

52\times 300\\\\=15600.

Therefore, it would cost 15600 to provide coffee for the whole year.

of course, you can always use  (x-1)(x-1)(2x+1)(x²-4x+5)  as well.
