<h2>Probability that the second marble will be blue is 0.44</h2>

Step-by-step explanation:

There are 10 marbles in a bag. 3 are red, 4 are blue, 2 are green, and 1 is yellow.

Total number of marbles = 10

Given that first marble is yellow.

New total number of marbles = 10 - 1 = 9

Now we have 3 are red, 4 are blue, 2 are green.

Number of blue marbles = 4

We need to find drawing probability of blue marble from 9 marbles.

Let the probability be, p

                   p=\frac{\texttt{Total blue marbles}}{\texttt{Total number of marbles}}\\\\p=\frac{4}{9}\\\\p=0.44

Probability that the second marble will be blue is 0.44

igomit [66]

Answer:

The linear equation used to find the cost to rent the shoes is 24.75+x=32

Cost to rent the shoes is $7.25.

Step-by-step explanation:

Given:

Cost of per game of bowling = $4.95

Number of games played = 5

Total money paid = $32

We need to find the cost to rent the shoes.

Solution:

Let the cost to rent the shoes be 'x'.

So we can say that;

Total money paid is equal to sum of Cost of per game of bowling multiplied by Number of games played and cost to rent the shoes.

framing in equation form we get;

5\times4.95+x=32\\\\24.75+x=32

Hence The linear equation used to find the cost to rent the shoes is 24.75+x=32

On solving the above equation we will find the value of 'x'.

Now we will subtract both side by 24.75 we get;

24.75+x=32-24.75\\\\x= \$7.25

Hence Cost to rent the shoes is $7.25.
