The graph is not a function, as it does not pass the vertical line test. The lines at 2,-1 and 2,3 overlay and pass the vertical line more than once, meaning that the graph is not a function.

Two of the cards of an ordinary deck of 52 cards are lost. What is the probability that a random card drawn from this (defective

Nostrana [21]

Answer:

0.72

Step-by-step explanation:

Given :Two of the cards of an ordinary deck of 52 cards are lost.

To Find : What is the probability that a random card drawn from this (defective) deck is a spade?

Solution:

Total number of cards = 52

2 cards are lost

Remaining cards = 50

When no spade card is lost

So, No. of spade cards = 13

Total cards = 50

So, probability of getting spade = $\frac{13}{50}$

When 1 spade card is lost

So, No. of spade cards = 12

Total cards = 50

So, probability of getting spade = $\frac{12}{50}$

When 2 spade cards are lost

So, No. of spade cards = 11

Total cards = 50

So, probability of getting spade = $\frac{11}{50}$

So, The he probability that a random card drawn from this (defective) deck is a spade = $\frac{13}{50}+\frac{12}{50}+\frac{11}{50}$

= $\frac{36}{50}$

= [tex]0.72/tex]

Hence the probability that a random card drawn from this (defective) deck is a spade is 0.72

we conclude that when we evaluate in x = 7, the given expression is equal to 12.

<h3></h3><h3>How to evaluate the expression?</h3>

Here we have the expression:

6*(x - 5)

Which represents the product of 6 and the sum between x and negative 5.

We want to evaluate it in x = 7, that means just replacing the variable in the given expression by the number 7, and then solving the expression.

Let's do that:

6*(7 - 5) = 6*(2) = 12

In this way, we conclude that when we evaluate in x = 7, the given expression is equal to 12.
