8. Identify the mapping diagram that represents the relation and determine whether the relation is
Over [174]

Answer:

Well, you didn't give a picture of the available mapping diagrams, so I can't tell you that.  However, I CAN tell you that the relation is not a function.

Step-by-step explanation:

A function occurs when each input only has one output.  For example if the input is 5, it can only give 1 y-value out.  It cannot give 2,3,4...etc values.  This relation is not a function because -5 maps to both -4 and 3.  That's one input to two outputs, which breaks the rules of a function.

In a game a player draws and replaces a card from a deck 2 times. The possible outcomes and payouts are shown. What is the
Goshia [24]

<u>Given</u>:

Given that in a game a player draws and replaces a card from a deck 2 times.

The possible outcomes and payouts are given.

We need to determine the expected value for someone playing the game.

<u>Expected value:</u>

The expected value for someone playing the game can be determined by

EV=(\frac{26}{52})(\$ 20)+(\frac{52}{52})(\$4)+(\frac{52}{52})(\$ 0)+(\frac{26}{52})(-\$12)

Simplifying the values, we have;

EV=(\frac{1}{2})(\$ 20)+(1)(\$4)+(1)(\$ 0)+(\frac{1}{2})(-\$12)

Dividing the terms, we get;

EV=\$ 10+\$4+\$ 0+-\$6

Adding, we have;

EV=\$ 8

Thus, the expected value for someone playing the game is $8

You have three online accounts and three different banks valued at: bank “A” $250.67, 12% interest, bank “B” $765.13, 7% interes
larisa [96]

The average interest gained from three accounts in one year is $913.224

<u>Explanation:</u>

Given:

Bank A:

Principal, P₁ = $250.67

Rate, r₁ = 12 %

Bank B:

Principal, P₂ = $765.13

Rate, r₂ = 7 %

Bank C:

Principal, P₃ = $28500.36

Rate, r₃ = 9 %

Interest from Bank A:

Interest = \frac{p X r X t}{100}\\\\I = \frac{250.67 X 12 X 1}{100} \\\\I = 30.0804

Interest from Bank B:

Interest = \frac{p X r X t}{100}\\\\I = \frac{765.13 X 7 X 1}{100} \\\\I = 53.5591

Interest from Bank C:

Interest = \frac{p X r X t}{100}\\\\I = \frac{28500.36 X 9 X 1}{100} \\\\I = 2565.0324

Average interest gained from three accounts in one year :

I = \frac{30.0804+53.5591+2656.0324}{3} \\\\I = 913.224

Therefore, average interest gained from three accounts in one year is $913.224
