Answer:
0.25
Step-by-step explanation:
Given:
Number of pens in a box = 10
Number of pencils in a box = 15
To find: probability of selecting a pen and then a pencil
Solution:
Probability refers to the chance of occurring of some event.
Probability of selecting a pen and then a pencil = (Probability of selecting a pen) × (Probability of selecting a pencil given that a pen has already been drawn)
[tex]=\frac{10}{25}\times \frac{15}{24}=\frac{150}{600}=\frac{1}{4}=0.25[/tex]
Probabilities are used to determine the chances of events
The probability of selecting a pen and then a pencil is 1/4
The samples are given as:
[tex]Pen = 10[/tex]
[tex]Pencil = 15[/tex]
The total number of items in the box is:
[tex]Box = 10 + 15[/tex]
[tex]Box = 25[/tex]
The required probability is then calculated as:
P = P(Pen) * P(Pencil)
So, we have:
[tex]P =\frac{10}{25} \times \frac{15}{24}[/tex]
Evaluate the product
[tex]P =\frac{150}{600}[/tex]
Simplify
[tex]P =\frac{1}{4}[/tex]
Hence, the required probability is 1/4

Cedric has 200 songs on his Apple Music account. Of these songs, 24 are Indie songs. What percent of Cedric's songs are Indie songs?
Answer:
12%
Step-by-step explanation:
First put it into a fraction 24/200
Half it to make it to 100%
12/100=100%
Final answer:
To find the percentage of Cedric's songs that are Indie songs, divide the number of Indie songs by the total number of songs and multiply by 100%. The percentage of Indie songs is 12%.
Explanation:
To find the percentage of Cedric's songs that are Indie songs, we need to divide the number of Indie songs by the total number of songs and then multiply by 100.
So, the percentage of Indie songs is calculated as:
Percentage of Indie songs = (Number of Indie songs / Total number of songs) * 100% = (24 / 200) * 100% = 12%.

1. Compare subtracting 10/8 - 4/8 to subtracting 10-4. How are they alike? How
are they different?
The subtraction of 10/8 - 4/8 is similar to 10-4 only in the general subtraction process, but they differ in the types of numbers used (fractions vs. whole numbers) and the results generated (a fraction vs. a whole number).
Explanation:The process of subtracting 10/8 - 4/8 is similar to subtracting 10-4 because in both cases, you are subtracting one number from another (~subtraction process~). However, they are different in terms of the kind of numbers used for subtraction. In the first operation, we are subtracting fractions while in the second operation, we are subtracting whole numbers.
To elaborate, in 10/8 - 4/8, they have the same denominators (8), so it's straightforward to subtract the numerators (numbers on top of the fraction): 10 - 4 = 6. So, the result is 6/8, which simplifies to 3/4.
In 10 - 4, the operation is simpler because we are working with whole numbers. By subtracting 4 from 10, we get 6 as the result. So, the results of the operations bear another difference, one yields a fraction, the other yields a whole number.

Salma suggested they sol a Grande box with 24 cupcakes. The ratio of
chocolate to vanilla cupcake is the same ratio of chocolate to vanilla for the
small box. Salma says that she can use equivalent ratios lo find how many
cupcakes in the Grande box are chocolate. What does she mean by that? How
many chocolate cupcakes will that be?
Answer:
12... If there is an even ratio between the two, then there is an even amount, so you divide 24 by 2 and you have 12 chocolate and 12 vanilla cupcakes in the Grande box.
Step-by-step explanation:
It izz wat it izzzz!!!
:)
Answer:
If the ratio of chocolate to vanilla cupcakes is the same, that would make there 12 chocolate and 12 vanilla cupcakes. She means that she can use equivalent ratios by, lets say the grande box had 100 cupcakes, then we know 50 are chocolate. We don't know how many chocolate cupcakes that will be because we don't know how much bigger the bigger box of cupcakes is.

Which of the following expressions is equivalent to the expression 2(7x+3)
A 9x+3
B. 14x +6
C. 9x-6
D. 14x-3
The formula 2(7x+3) can be translated into 14x +6 using the distributive property of multiplication over addition (Option B).
Explanation:The expression 2(7x+3) is equivalent to the expression 14x+6. Such mathematical expressions are related to the concepts of algebra, specifically, the distributive property of multiplication over addition. This property allows the distribution of 2 over the terms inside the parentheses, 7x and 3 in this case. When we multiply 2 by 7, we get a result of 14, and when we multiply it by 3, we get a result of 6. So, option B: 14x + 6 is the correct response to this question.

which expression is equivalent to 3x/5
a: 15x/20
b: 12x/20
c: 12x/5
Answer: 12x/20
Step-by-step explanation:
Looking at 3x/5
The expression equivalent is 12x/20
The reason is this
12x/20
If you divide the 12x by 4
It will give you 3x
If you divide 20 by 4
It will give you 5
Therefore, you will still have 3x/5
Another way to look at it is this
3x/5= 0.6x
12x/20= 0.6x
Therefore, the final answer is b which is 12x/20

-20a -8 + 12b is ? what is the answer?
Answer:
4(-5a + 3b - 2)
Step-by-step explanation:
Aside from changing the order of the terms so that the "a" term comes first and the "b" term second, there's nothing you can do with this expression -20a -8 + 12b. But notice that 4 is a factor common to all three terms, and therefore it can be factored out:
Rearranging the terms, we get
-20a + 12b - 8 = 4(-5a + 3b - 2)
Answer:
The answer is -4(5a+2-3b)

There are 5 red marbles, 4 blue marble, 2 green marbles, and 1 yellow marble in the bag. What is the probability of pulling out each of the following?
Answer:
Red : 5/12
Blue : 1/3
Green: 1/6
Yellow : 1/12
Step-by-step explanation:
5 red marbles + 4 blue marbles + 2 green marbles + 1 yellow marble = 12 total marbles
5 red marbles / 12 total marbles = 5/12
4 blue marbles / 12 total marbles = 4/12 = 1/3
2 green marbles / 12 total marbles = 2/12 = 1/6
1 yellow marbles / 12 total marbles = 1/12
What is the slope of the line shown in the graph?
A 3/2
B 2/3
C -3/4
D - 2/3
Answer:
D. -2/3
Step-by-step explanation:
Since it is going down, it is negative
Think of this: Rise/Run
In this case, rise is when you are going up or down the graph
Run is when you are going to the right of the graph
Let's use 2 points (0,3) and (3,1)
Since you are going three points to the right we are going to put 3 in for run
You are going 2 places down, so we are going put -2 in for rise
This gives us -2/3
Another way to do this is (1-3)/(3-0) = -2/3
