a) The number of ways that she can arrange the 9 paintings is; 362880 ways

b)  If she only wants to display 5 of the paintings, the number of ways can she choose the paintings she wishes to display is; 126

c) The number of ways can she arrange 5 out of 9 paintings is; 120

a) If we take 9 paintings to be hung in 9 spaces arranged side by side, then it means that the first space can have any one of the 9 paintings, the second space can have any one of the remaining 8 paintings (as 1 is already hung), the third space can have any one of the remaining 7 paintings (as 2 already hung) e.t.c

Thus;

Number of ways to arrange all the paintings from left to right = 9! = 362880

b) We are now told that she only wants to display 5 of the paintings. Thus;

Number of ways she can choose the paintings she wishes to display is done by the combination formula;

nCr = n!/(r!(n - r)!)

9C5 = 9!/(5!(9 - 5)!)

= 126 ways

c) Any 5 of the 9 paintings can be arranged in;

The graph shown in the question is representing the equation y = log x, so option 3 is correct.

A collection of objects is arranged in a graph, where some object pairings are conceptually "linked." Each pair of connected vertices is referred to as an edge, and the objects are represented by mathematical abstractions known as vertices.

Given:

The graph is shown in the image,

Put the value of x and y from the graph to the equation as shown below,

x = 1, y = 0

Put in option 1,

y = log5 x

0 = log5

0 = 0.69

Again, put in option 2,

y = log x

0 = log1

By solving equations, we know that the number of apples and mangoes purchased is 8 and 2, respectively.

In a mathematical equation, the equals sign is used to express that two expressions are equal.

Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions.

For instance, the expressions 3x + 5 and 14 make up the equation 3x + 5 = 14, with the word "equal" separating them.

So, we know that:

Apple and mango are worth $13.50.

Each mango costs $0.75, but each apple costs $1.50.

Let the number of apples be x and the number of mangoes be y, so that:

1.50x + 0.75y = 13.50

Fewer apples than mangoes by six That is to say,

x = y + 6

x - y = 6

The two resulting equations are:

1.50x + 0.75y = 13.50

x - y = 6

The simultaneous equation's solution provides

x = 8

y = 2

Therefore, by solving equations, we know that the number of apples and mangoes purchased is 8 and 2, respectively.

The angle x of the triangle is 68 degrees and the side y is 7.5 units.

The triangle ABC is a right angle triangle because it has one angle as 90 degrees. The sum of the angles in the triangle is 180 degrees.

The angle ECD is congruent to angle ACB(vertically opposite angles).

Therefore,

∠ECD ≅ ∠ACB

Hence,

x = 180 - 90 - 22

x = 68 degrees.

using trigonometric ratios, let's find y

cos 22 = adjacent / hypotenuse

sin 22 = 2y - 1 / 15

cross multiply

15 cos 22 = 2y - 1

2y - 1 = 13.9077578185

2y = 13.9077578185 + 1

2y = 14.9077578185

divide both sides by 2

y = 14.9077578185 / 2

y = 7.45387890925

Angle ACD is congruent to angle ADC by transitive equality if angles 1 and 2 are both ACD because angle ACB is congruent to angle ADE in the step above. Therefore, angle 1 equals angle 2, as you can see.

An isosceles triangle in geometry is a triangle with two equal-length sides. It can be stated as having exactly two equal-length sides or at least two equal-length sides, with the latter definition containing the equilateral triangle as an exception.

Here,

Given that segments AB and AE are congruent, the triangle ABE is required to be isosceles by definition.

As a result, angle ABC must be similar to angle AED, again in accordance with the definition of an isosceles triangle.

Consequently, triangle ABC must be congruent to triangle AED by SAS as you have been informed that segments BC and DE are congruent. Right now, it's unclear to you whether angle 1 is ACB or ACD.

Assuming it is ACB, CPCT shows that ACB is congruent to ADE. Angle 1 equals angle 2, so there you have it. Since angle ACB is supplementary to angle ACD and angle ADE is supplementary to angle ADC.

Since angle ACB is congruent to angle ADE from the step above, angle ACD is congruent to angle ADC by transitive equality if angle 1 and angle 2 are both ACD. Angle 1 equals angle 2, so there you have it.

A line segment in geometry is a section of a straight line that is enclosed by two clearly defined end points and contains all of the points on the line that lie within those endpoints. The Euclidean distance between two endpoints of a line segment determines its length.

- In this diagram, line segment CD is the  perpendicular bisector of line

segment  AB

∴ AB ⊥ CD

∵ CD intersect AB at M

∴ M is the mid-point of AB

∴ The length of  AM = the length of MB

- Assume the conjecture that the set of  points equidistant from A

and B is the  perpendicular bisector of AB is true

∴ Any point lies on the line CD equidistant from A and B

- If point E lies on the line CD

∵ CD is the perpendicular bisector of AB

∵ E lies on CD

∴ The length of EA = The length of EB

- From the figure point E is on the left side of the line CD

∵ Point A is on the left side of the line CD

∵ Point B is on the right side of the line CD

∵ Point E is on the left side of the line CD

∴ The length of AE < The length of BE

When we reject the null hypothesis and the null hypothesis is true, we have made a Type I error.

In statistical hypothesis testing, the null hypothesis is a statement that represents the anticipated or "normal" outcome of a specific experiment. Unless there is evidence to the contrary, the null hypothesis, which is generally represented by the symbol "H0," is taken to be true.

A Type I mistake, sometimes known as a "false positive," arises when the null hypothesis is correct but is rejected based on the evidence. Applying a statistical test with a strong significance level increases the likelihood of rejecting the null hypothesis even when it is correct, which frequently leads to this mistake.

Making a Type I error can have major repercussions since it can result in judgments being formed based on flawed information and wrong inferences being drawn.
