Answer:

9/64

Step-by-step explanation:

So, we need to find the probability of drawing a blue marble the first time. There are a total of 8 marbles, and 3 blue marbles. So, the probability for the FIRST PULL will be:

3/8

Now, you REPLACE it meaning the value will stay the same. So now you just multiply.

3/8 * 3/8 = 9/64

Hope this helps !!

Answer:

9/64

Step-by-step explanation:

1 red marble, 3 blue marbles, and 4 green marbles = 8 marbles

1st draw:

P( blue) = blue / total = 3/8

We replace the marble

1 red marble, 3 blue marbles, and 4 green marbles = 8 marbles

2nd draw:

P( blue) = blue / total = 3/8

P(blue, replace, blue) = 3/8 *3/8 = 9/64

Red roses come 3 to a package, and white roses come 5 to a package. If an equal number of red and white roses are wanted to make
Katen [24]

Answer:

B :- 15

Step-by-step explanation:

Given:

A package of red rose contains = 3 pieces

A package of white rose contains = 5 pieces

If an equal number of red and white roses are wanted to make bouquets, what is the minimum number of each that can be purchased ?

Solution:

As here given that there are two types of package of roses, red roses come 3 pieces to each packet and white roses come 5 pieces to each packet and we have to find equal minimum number of  red roses as well as white roses to be purchased, we will simply find the Lowest common multiple of 3 and 5.

Multiples of 3 :- 3, 6, 9,12, 15, 18, 21, 24

Multiples of 5 :- 5, 10, 15, 20, 25

<em>Lowest common multiple is 15, that means </em><em>15 is the minimum number of pieces of each that can be purchased to make bouquets.</em>

And number of packets of red rose have to purchase = 3 \times <em><u>5</u></em> = 15, 5 packages.

And number of packets of white rose have to purchase = 5 \times <em><u>3</u></em> = 15 , 3 packages.

Taking into account the definition of percentage, the correct option is: 21 percent of her net pay is left for savings.

First of all, the percentage represents a given quantity that establishes relationships between two quantities, using the number 100 as a reference.

That is, the percentage indicates what part of a total represents a quantity.

To obtain the percentage, the division must be made between the portion of the total and the total amount that belongs to the set, whose result is multiplied by 100.

In this case, if Lillie's current monthly net pay and her monthly expenses are $ 387.10, and I assume that the rest of the money is saved by Lillie, then the amount of money saved is $ 490 - $ 387.10 = $ 102.9.

Then:

  • portion of the total= amount of money saved= $102.9
  • total amount= Lillie's current monthly net pay= $490

So, the percentage is calculated as:

percentage= (102.9÷490) ×100

percentage= 0.21×100

percentage= 21%

The correct option is: 21 percent of her net pay is left for savings.
