Answer:

Every year, the bear population shrinks by a factor of 2/3 .

Explanation:

The concrete question and the function or data were omitted.

I found the complete question on the internet. Please, find attached the picture with the complete question

You must complete the sentence about the yearly rate of change of the bear population, telling whether it grows or shrinks and by what factor.

Thus, the goal is to interpret the rate of change in an exponential model.

The exponential model is:

$N(t)=2187\cdot \bigg(\dfrac{2}{3}\bigg)^t$

Let's analyze that function.

When t = 0, (2/3)⁰ = 1 and N(0) = 2,187 × 1 = 2,187

Thus, the population of bears starts with 2,187 individuals.

For t = 1, the population will be N(1) = 2,187 × (2/3).

For t = 2, the population will be N(2) = 2,187 × (2/3)²

And so on, every year the population of bears is multiplied by a factor of 2/3.

Since, 2/3 is less than 1, every year the population will be decreasing (decaying), by a factor of 2/3.

Thus, the answer, i.e. the complete sentence, is:

Every year, the bear population shrinks by a factor of 2/3 .

Write the equation of the line that passes through the points (-2,6) and (4, 6). Put

ivolga24 [154]

Answer:

y = 6

Step-by-step explanation:

Lets first try to find the slope between the two points. Note, if the slope is 0, then the line would be a horizontal line. If the slope is undefined, then it is a vertical line.

We can use the slope formula to find the slope between the two lines, but notice something. The slope formula is technically just the change in y divided by the change in x. Between the two points, the y-value does not change and the x-value does change. This means that the change in y is 0, but the change in x is not zero. This means that the slope would be 0, resulting in a horizontal line.

Now, we know that the resulting line is horizontal, meaning it will take the form of y = _. Since the y-values for both of the points is 6, it makes sense to say that the equation for the line would be y = 6.

I hope this helps. Happy studying.

The New York museum attracted 6,274,289, while the Chicago museum attracted 5,772,857.

Round to the nearest million. Note that if the number in the hundred-thousands place value is 5 or greater, round up. If it is 4 or less, round down.

6,274,289 => 6,000,000

5,772,857 => 6,000,000

Combine the two terms

6,000,000 + 6,000,000 = 12,000,000

a) 12,000,000 is your answer

hope this helps

A person is chosen at random from a room that contains 24 men and 26 women. What is the probability that a woman is chosen?

Shkiper50 [21]

Answer:

C.13/25

Step-by-step explanation:

There are 50 people in total and 26 out of them are women

if a person chosen randomly from the room the probability of it being a woman is 26/50 whıich we can simplify to 13/25
