A population of insects doubles every month. This particular population started out with 20 insects. Write an equation to model this scenario.

Answers

2x+20, x being a month.

Final answer:

The scenario describes the exponential growth of an insect population that doubles every month, starting from 20 insects. The appropriate mathematical model for this scenario is the equation P = 20 * 2^n, where P is the final population, and n is the number of months.

Explanation:

The given scenario describes the exponential growth of a population of insects where the population doubles every month. To represent this mathematically, we can use the formula for exponential growth which is: P = P0 * 2^n. In this formula, P is the final population, P0 is the initial population (which is 20 insects in this case), 2 represents that the population doubles, and n is the number of time periods (months in this case).

So, the equation to model this scenario will be P = 20 * 2^n.

Answer:

(6,12)

Step-by-step explanation:

Use the mid point formula to find the answer. Add the first x value to the second and divide by two for your x midpoint, then add the first y value to the second y value and divide by two for your y midpoint.

In Missy's sport-card collection, 3/4 of the cards are baseball cards. In frank's collection, 8/12 are baseball cards. Frank says they have the same fraction of baseball cards. Is he correct?

Answers

to solve this, you need to simplify 8/12
in order to simplify a fraction, you divide both the top and bottom by the same number.
 8 and 12 are both divisible by 4, so you get
2/3

2/3 and 3/4 are not the same fraction, so no. Frank is not correct.
No he is incorrect because Missy's collection has more.

The chart below shows the number of cakes Jenny bakes each month.What is the mean number of cakes Jenny bakes in a month?

Answers

Since you didn't put any chart above, then I'll just give an idea on how to find the mean. You simply compute for the sum of the cakes Jenny bakes each month. Then, you proceed to dividing the number of cakes by the number of months indicated in the chart. You should have the mean by now.
