You spin the spinner once. 123 What is P(odd or divisor of 54)? Simplify your answer and write it as a fraction or whole number.

Answer:

Step-by-step explanation:

\(w=(\frac{1}{7}).V_{1}+(\frac{4}{7}).V_{2}\)

We have the following vectors :

\(w=\left[\begin{array}{c}3&-1&2\end{array}\right]\)

\(V_{1}=\left[\begin{array}{c}-3&1&2\end{array}\right]\)

\(V_{2}=\left[\begin{array}{c}6&-2&3\end{array}\right]\)

In order to express \(w\) as a linear combination of the vectors \(V_{1}\) and \(V_{2}\), we will search for \(a,b\) ∈ IR such that :

\(a.V_{1}+b.V_{2}=w\)      (I)

Now we are going to work matrixically with the equation (I) :

\(a\left[\begin{array}{c}-3&1&2\end{array}\right]+b\left[\begin{array}{c}6&-2&3\end{array}\right]=\left[\begin{array}{c}3&-1&2\end{array}\right]\)

Distributing mathematically and matching ''component to component'' we lead to the following equations :

\(-3a+6b=3\\a-2b=-1\\2a+3b=2\)

Working with the system associated matrix :

\(\left[\begin{array}{ccc}-3&6&3\\1&-2&-1\\2&3&2\end{array}\right]\)

Applying matrix operations we lead to the following equivalent matrix :

\(\left[\begin{array}{ccc}1&0&\frac{1}{7}\\0&1&\frac{4}{7}\\0&0&0\end{array}\right]\)

In this matrix we obtain that :

\(a=\frac{1}{7}\)  and \(b=\frac{4}{7}\)

We can verify this solution by replacing the values of \(a\) and \(b\) in the equation (I) :

\((\frac{1}{7}).V_{1}+(\frac{4}{7}).V_{2}=w\)  ⇒

\((\frac{1}{7}).\left[\begin{array}{c}-3&1&2\end{array}\right]+(\frac{4}{7}).\left[\begin{array}{c}6&-2&3\end{array}\right]=\left[\begin{array}{c}3&-1&2\end{array}\right]\)    ⇒

\(\left[\begin{array}{c}3&-1&2\end{array}\right]=\left[\begin{array}{c}3&-1&2\end{array}\right]\)    

Answer:

C = 132°

Step-by-step explanation:

Step-by-step explanation:

The probability of Miguel selecting a tile number less than 3 from each bag -1 is 1/5 and bag-2 is 2/5.

The given tiles in bag-1 = {2, 4, 5, 8, 9}

Total number of tiles in bag-1 = 5

The number of tiles less than number 3 in the bag - 1 = 1

The probability of Miguel selecting a tile number less than 3 =

number of tiles less than 3 / total number of tiles = 1/3

The given tiles in bag-2 = {0, 1, 3, 6, 7}

Total number of tiles in bag-2 = 5

The number of tiles less than number 3 in the bag-2 = 2

The probability of Miguel selecting a tile number less than 3 =

number of tiles less than 3 / total number of tiles = 2/3

Only point Q is on the ∠MNO because when we connect the point M and O then point R lies outside the ∠MNO. Only point Q remains inside.

In the given question we have to name a point on ∠MNO.

As we know that;

Evaluating the number of points in the curve of the triangle's vertices that are close to the location in question is the easiest method for determining whether a point is inside a triangle. The point on the curve is inside the triangle if it has three points; if it has four, it is outside the triangle.

When we check in the graph then only point Q is on the ∠MNO because when we connect the point M and O then point R lies outside the ∠MNO. Only point Q remains inside.

The value of csc(270) is undefined.

What is undefined in trigonometry?

Trigonometric functions are undefined when they represent fractions with denominators equal to zero. Cotangent is the reciprocal of a tangent, so the cotangent of any angle x for which tan x = 0 must be undefined since it would have a denominator equal to 0.

The unit circle is a circle with a radius of 1 that is centered at the origin of a coordinate plane.

The coordinates of a point on the unit circle can be represented in terms of sine and cosine.

To find coc(270), we can use the relationship between the cosecant function and the sine function, which is csc(x) = 1/sin(x).

We know that sin(270) = 0, so the csc(270) = 1/0, which is undefined.

Hence, the value of csc(270) is undefined.

Answer:

Step-by-step explanation:

Here the function is f(x) = 7 - 8x.  x is the independent variable.  f(a) is the value of the function when x = a.

To find the value of f(a), we start with f(x) = 7 - 8x and replace each instance of x with a:

f(a) = 7 - 8a

To find the value of f(a + h), we start again with f(x) = 7 - 8x, but this time we replace each instant of x with (a + h):

f(a + h) = 7 - 8(a + h), or 7 - 8a - 8h.

To find f(a + h) - f(a), we write out the terms of f(a + h) followed by those for f(a) and then combine like terms:

7 - 8a - 8h - {7 - 8a) => -8h

Thus,

f(a + h) - f(a) = -8h

Answer:

William can find how many piano pieces he has learned by using the equation y = 2x.

Step-by-step explanation:

We are given that William learns two piano pieces per week.

We are tasked with finding the equation that represents this relationship (the number of weeks that William has received piano lessons and the total number of piano pieces that William has learned).

Therefore, take for example that William has been taking piano lessons for four months. This would roughly equate to sixteen weeks.

After analyzing this, we know that he learns two pieces a week. So, we can multiply our number of weeks by two in order to receive the total amount of pieces learned.

Finally, we need to set this equal to the total number of pieces learned, or our previously defined variable y.

In mathematics, we want to simplify everything as much as possible. There is a statement that if a constant and a variable are to be multiplied, we can remove the multiplication symbol and place the constant and the variable together.

Therefore, our equation is \(\bold{y = 2x}\).

There are 15 men in total;

If each committee is to have 8 men (and assuming one man cannot be in multiple committees), we can simply do the following:

15/8 = 1.875

This means only 1 committee can be made containing exactly 8 men.

You can also think of it like this:
If 8 men make up 1 committee, then this leaves 7 (15 - 8) men left;

Since you need 8 men, there is not enough for a second committee (once again, assuming that one man cannot be in more than one committee).

Step-by-step explanation:

I think that it will be harder to get the strong magnets to change phase​ because tighter molecules, for example, solids have a higher molecular attraction. The amount of temperature is very important too because the higher amount of temperature produced, the more kinetic energy distributed. The more kinetic enery the molecules contain, the more they move. Magnets are solid molecules. Solid molecules stick together and don't move separately like gas molecules, meaning that they have a low amount of kinetic energy.

Yes, it will be harder to get the strong magnets to change phase​.

Because  in this molecule are closely packed, for example in solids, there is no space between the molecules atoms, therefore, they have higher force of attraction.

So, they are strongly bonded to each other. Solids need high amount of energy to break the bond.

That is, the increase in temperature causes movement in molecules. Magnets are also solid molecules.

Solid molecule bonded together not move freely like gaseous molecules, means that they have a low amount of kinetic energy.

Numbers 1 and 2 are correct.

Question 3:

We can see in each figure, the number of rows matches the figure amount. For example, figure 1 has 1 row, figure 2 has 2 rows, figure 3 has 3 rows, etc. Another thing we can see is that one block gets added to each column in every figure. If we count starting from 3 and keep adding 1 for each column, we get 22 blocks for one column. In figure 20, there will be 20 rows and 22 columns. We also have to keep in mind that they add 2 extra blocks at the top and bottom that stick out like the ones shown. In total, figure 20 will consist of 442 blocks.

Question 4:

[(2 + f) * (f)] + 2 = b

(2 + f) represents the number of blocks in each column.

(f) represents the number of blocks in each row.

2 represents the two extra blocks in each figure.

Note that f in this equation equals the number of the figure. For example, figure 3 is f = 3

We can test our equation with figure three.

[(2 + f) * (f)] + 2 = b

We have figure three so f = 3. Substitute and solve.

[(2 + 3) * (3)] + 2 = b

[5 * 3] + 2 = b

15 + 2 = b

17 = b

In the example, the number of blocks is 17. Therefore, this equation works for any figure.

Best of Luck!

Answer:
