<span>The geometric mean is defined the nth root of the product of n number. The formular is given as n√ a1 * a2 * a3 * ... where an are the the values of the sample. Here there are 2 numbers so n = 2 Our geometric mean = 2√ 18 * 2 = 2 √36 = √36 = 6</span>

Answer:

$3,000 was invested in the account that gained 13%

$17,500 was invested in the account that lost 10%

Step-by-step explanation:

Let the amount in both accounts be x and y

x for the first and y for the second

Adding both is 20,500

x + y = 20,500 •••••(i)

First account earned 13% profit

= 13/100 * x = 0.13x

Second account, a loss of 10%

= -10/100 * y = -0.1y

Total loss of -1,360

This is;

-0.1y + 0.13x = -1,360 •••••••(ii)

From i, x = 20,500-y

Insert this into ii

-0.1y + 0.13(20,500-y) = -1,360

-0.1y + 2665 -0.13y = -1360

-0.23y = -1360-2665

-0.23y = -4025

y = -4025/-0.23

y = 17,500

To get x, we have

x = 20,500 -y

x = 20,500- 17,500

x = 3,000

An experiment is performed where a 6-sided die is rolled and then a 3-color spinner is spun. The possible outcomes for each even

Galina-37 [17]

It should be noted that the sample space for the experiment is {1R, 1B, 1Y, 2R, 2B, 2Y, 3R, 3B, 3Y, 4R, 4B. 4Y. 5R, 5B, 5Y, 6R, 6B, 6Y}

<h3>What is a sample space?</h3>

A sample space is a set of potential results from a random experiment. The letter "S" is used to denote the sample space. Events are the subset of possible experiment results. Depending on the experiment, a sample area may contain a variety of outcomes.

Total number of outcomes in this experiment = 6 × 3 = 18

Hence, the sample space will be:

{1R, 1B, 1Y, 2R, 2B, 2Y, 3R, 3B, 3Y, 4R, 4B. 4Y. 5R, 5B, 5Y, 6R, 6B, 6Y}
