alekssr [168]

If the initial population is 3800. Then the population of the cockroach after 3 years will be 1603.

<h3>What is exponential growth or decay function?</h3>

Consider the function:

y = a(1 ± r)ⁿ

where n is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.

If there is a plus sign, then there is exponential growth happening by r fraction or r%.

If there is a minus sign, then there is exponential decay happening by r fraction or r%.

Colette has an exterminator visit regularly to control an ongoing cockroach problem.

It's been working, and the population has declined by 15% every year.

If the population is currently 3,800 cockroaches.

The expression is given as

y = 3800(0.75)ⁿ

Then the population of the cockroach after 3 years will be

y = 3800(0.75)³

y = 3800 x 0.4218

y = 1603.125

y ≅ 1603

The difference of mean for the given set of terms including the outlier and excluding the outlier is 1.01.

<h2>Mean</h2>

The arithmetic mean for a given set of numbers is defined as the central value for the given set of numbers.

Given that Sasha runs a 5k race. Her time in minutes is recorded in the table:

  • Jan 39. 55
  • Feb 40. 51
  • Mar 41. 01
  • Apr 37. 76
  • May 35. 32
  • June 33. 28
  • July 34. 38  
  • Aug 36. 48  
  • Sept 39. 87  
  • Oct 50. 32  
  • Nov 40. 59
  • Dec 41. 71.

The mean for the given set of terms can be calculated by the total sum of all the terms divided by the total number of terms.

Mean = \dfrac {39. 55+40. 51+41. 01+37. 76+35. 32+33. 28+34. 38+36. 48+39. 87+50. 32 +40. 59+41. 71} {12}

Mean = 39.23

Thus the mean of the given set of terms is 39.23.

The outlier term in the given set of terms is 50.32. If we exclude this outlier term, then the mean will be given as below.

Mean = \dfrac {39. 55+40. 51+41. 01+37. 76+35. 32+33. 28+34. 38+36. 48+39. 87+40. 59+41. 71} {11}

Mean = 38.22

The difference between the mean including the outlier and excluding the outlier is given below.

Difference = 39.23 - 39.22

Difference = 1.01

Hence we can conclude that the difference of mean for the given set of terms including the outlier and excluding the outlier is 1.01.
