Total ways to select the books are 24 and   this can be solved using simple permutation and combination.

What is permutation and combination?

By selecting some things from a group and making subsets, permutation and combination area unit 2 approaches to represent a bunch of objects. It outlines the various configurations for a selected set of information. Permutations area unit the choice of information or objects from a group, whereas mixtures area unit the order during which they're painted.

Main Body:

a) 1. First book can be at any of 4 places

   2. Second book can be on any of leftover 3 places

   3. Similarly third book on 2 and forth on 1 place

total : 4*3*2*1 = 24 ways .

other way we have formula 4!/1! =24

b) There are n! ways to choose an order for the books. Once chosen this           order, we have to place k−1 bars between the books to determine where   ends a shelf and begins the next one. This is like rearrange a set of n    books and k−1 bars, and there are (n+k−1, C,n) ways to do this.

⇒(12+4-1 C 4)

⇒¹⁵C₄

⇒7560 ways

hence total no. of ways = 7560.

Step-by-step explanation: 5/20+2+5/20+2+4/20+2=6 7/10

The equation of the line is 4y +3x -6 = 0

A line passes through the point (-2, 3) and is parallel to the line y=- 3/4x+4

y=- 3/4x+4 is in slope intercept form

y = mx + c

Where m is the slope of the given line

y=- 3/4x+4

In this line the slope is -3/4

The slope of two parallel line is same

The point is (-2, 3)

The equation of the line is

y - y₁ = m(x - x₁)

y - 3 = -3/4(x - (-2))

4(y - 3) = -3(x + 2)

4y - 12 = -3x -6

4y + 3x = -6 + 12

4y +3x -6 = 0

Therefore, the equation of the line is 4y +3x -6 = 0

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

The triangles are similar   so

x + 46 + 78 = 180

x = 56°

The coordinates of X that partitions XY in the ratio 5 to 4 include the following: X (-1.6, -7).

In this scenario, line ratio would be used to determine the coordinates of the point X on the directed line segment AB that partitions the segment into a ratio of 5 to 4.

In Mathematics and Geometry, line ratio can be used to determine the coordinates of X and this is modeled by this mathematical equation:

M(x, y) = [(mx₂ + nx₁)/(m + n)],  [(my₂ + ny₁)/(m + n)]

By substituting the given parameters into the formula for line ratio, we have;

M(x, y) = [(5(2) + 4(-6))/(5 + 4)],  [(5(-11) + 4(-2))/(5 + 4)]

M(x, y) = [(10 - 24)/(9)],  [(-55 - 8)/9]

M(x, y) = [-14/9],  [(-63)/9]

M(x, y) = (-1.6, -7)

Additive inverse of 2 is -2.

Multiplicative Inverse of 2 is 1/2.

To produce a result equal to 0, add the original number and the additive inverse by simply reversing the sign of the integer. On the basis of negation of the original number, the characteristics of additive inverse are listed below. For instance, if x is the starting number, then -x is x's additive inverse.

A multiplicative inverse or reciprocal for a number x is a number that, when multiplied by x, produces the multiplicative identity, or 1. It is represented by 1/x or x/1. A fraction a/b has a multiplicative inverse of b/a. Divide 1 by the real number to obtain the multiplicative inverse of the number.

A function that "undoes" another function is called an inverse. In other words, if f(x) generates y, then y entered into the inverse of f creates x. An invertible function is one that has an inverse, and the inverse is indicated by the symbol \(f^{-1}\).

Answer:

(-infinity, -2/3)u(-2/3,0)u(0, infinity)

Step-by-step explanation:

since it is asking for f(g(x)) we plug g into x which looks like:

f(2/x)

now we plug that into the f(x) equation for all of the x's because that is what replaced the x so:

1/(2/x)+3

we look at the denominator so we can pull the 2/x+3 out and set it equal to zero, therefore solving for x

this gives us -2/3

and we get the 0 from g(x) 's denominator

that should be correct and hope this helps!

The probability that a student is taking calculus given that he or she is taking statistics is = 0.26

Step-by-step explanation:

the probability that a student is taking calculus given that he or she is taking statistics.

Let C = Calculus

S = Statistics

We solve this above Question nursing the formula;

P ( C ∪ S) = P(C) + P ( S ) - P ( C ∩ S)

From the question,

P(C) = 0.10

P( S ) = 0.18

P ( C ∩ S) = 0.02

P ( C ∪ S) = ???

P ( C ∪ S) = 0.10 + 0.18 - 0.02

= 0.28 - 0.02

= 0.26

The algebraic expression for half of a number is x/2.

When we are working in algebra and we want to represent "a number", we use a variable for it.

We do this because "a number" can be any real number.

For example, we can say that a number is represented by the variable x.

Now, to write half of a number, we just need to divide our variable by 2, then we will get:

The  expected value of the sum of the two balls is 5.

To solve this problem, we can use a table to list all the possible outcomes of drawing two balls from the bag and finding their sum. Here is the table:

| Ball 1 | Ball 2 | Sum |
|--------|--------|-----|
| 1      | 1      | 2   |
| 1      | 2      | 3   |
| 1      | 3      | 4   |
| 1      | 4      | 5   |
| 1      | 5      | 6   |
| 2      | 2      | 4   |
| 2      | 3      | 5   |
| 2      | 4      | 6   |
| 2      | 5      | 7   |
| 3      | 3      | 6   |
| 3      | 4      | 7   |

| 4      | 4      | 8   |
| 4      | 5      | 9   |
| 5      | 5      | 10  |

There are 15 possible outcomes, and each outcome has an equal probability of occurring, assuming that the balls are chosen randomly. To find the expected value of the sum, we need to take the sum of all the possible outcomes, weighted by their probabilities, which are all 1/15. So, we have:

E(sum) = (1/15)(2 + 3 + 4 + 5 + 6 + 4 + 5 + 6 + 7 + 6 + 7 + 8 + 8 + 9 + 10)
      = (1/15)(75)
      = 5

Therefore, the expected value of the sum of the two balls is 5.

Answer:

8(x+3) is the answer

Step-by-step explanation:

The equation is 6(x + 3) = 60. Then the solution of the equation is 3.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

The product of 6 and the sum of a number and 3 is 60.

Let the number be 'x'. Then the equation is written as,

6(x + 3) = 60

Simplify the equation, then the value of the variable 'x' will be calculated as,

6(x + 3) = 60

x + 3 = 60 / 6

x + 3 = 10

x = 10 - 3

x = 3

The equation is 6(x + 3) = 60. Then the solution of the equation is 3.

An obtuse angle is an angle that is greater than 90° but less than 180°.

We can see that the first shape has 2 angles that are greater than 90°, making this a correct choice.
The second shape has 4 boxes, meaning the angles are exactly 90°, making this incorrect.

The third shape has 6 angles that are greater than 90°, making this another correct choice.

The last shape has all 3 angles under 90°, making this also incorrect.

So, the 1st and 3rd shapes are correct.

The equation for breaking even is, 2x + 15 = 5x.

We have, Sandra makes and sells bracelets. It costs her $2 to make each bracelet, plus a one-time cost of $15 for supplies. She plans to sell each bracelet for $5.

Therefore we have,

The number of bracelets that Sandra needs to sell in order to break even can be solved by equating the total cost to her total revenue.

If the x represents the number of bracelets,

The total cost would be, 2x + 15.

Her total revenue from sales is expressed as 5x.

What is an linear equation in math?

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included.

The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

The two numbers are 15.75 and 176.3

First we will compare the numbers.

1. A=176.3

2. B=15.75

one's place of A is greater than once place of B.

tens place of A is greater than tens place of B.

Hundred place of A is greater than hundred place of B.

So, A>B

So  we will subtract 15.75 from 176.3.

176.30 -15.75=

176.30     ----A

- 1 5.75     ----B

Hundreths place of A - Hundreths place of B =  0-5=10-5=5

Tenth place of A  - Tenth place of B =12-7=5

ones place of A - ones place of B=5-5=0

Tens place of A - Tens place of B =7-1=6

Answer:

Unlikely

Step-by-step explanation:

There are more chances that tomorrow there will be no rain than the raining we can say that it is unlikely to rain tomorrow.

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

We have:

The weather forecast calls for a 20% chance of light rain tomorrow.

Probability of rain:

P(rain) = 20% = 0.2

Complement event: Not rain tomorrow

Probability of complement event P(not rain) = 1 – 0.2 = 0.8 or 80%

P(not rain) > P(rain)

Thus, there are more chances that tomorrow there will be no rain than the raining we can say that it is unlikely to rain tomorrow.
