The smallest and the largest area of the window will be 9.8 and 11.1 sq. metres respectively.

This problem is based on the area of rectangle .

Here, since the height and the width of the window are distinct, so the window can be assumed to be of rectangular shape.

Now, the area of a rectangle is given by = l x b where l and b are respectively the height and the width of the window respectively.

The area would be smallest when both the height and width are least i.e. 140 cm and 70 cm .

So, smallest area = lxb = 140 x 70 = 9800 sq. cm = 9.8 sq. m.

Similarly the largest area would be when both the height and the width are maximum i.e. largest area = lxb = 150x 74 = 11,100 sq cm. =11.1 sq metres.

Therefore, the smallest and the largest area of the window will be 9.8 and 11.1 sq. metres respectively.

Answer:

Step-by-step explanation:

The first five terms of the sequence are: 3, 12, 30, 66, 138.

To find the first five terms of the sequence a1 = 3, an+1 = 2an + 6, we need to repeatedly apply the formula for an+1 to find the next term.

Starting with a1 = 3, we can find a2 by substituting n = 1 into the formula:

a2 = 2a1 + 6 = 2(3) + 6 = 12

Next, we find a3 by substituting n = 2:

a3 = 2a2 + 6 = 2(12) + 6 = 30

Then, we find a4 by substituting n = 3:

a4 = 2a3 + 6 = 2(30) + 6 = 66

Continuing, we find a5 by substituting n = 4:

a5 = 2a4 + 6 = 2(66) + 6 = 138

This sequence is a geometric sequence with a common ratio of 2, meaning that each term is twice the previous term. The sequence is also increasing at an exponential rate.

b = 6 - (2)(-2)

= 6 + 4 = 10

u^3 + 8 factors as (u + 2)(u^2 + 2u + 4) is explained by kuta software infinite algebra as

x^3 + 125

To factor this expression, we can use the formula for the difference of cubes:

a^3 + b^3 = (a + b)(a^2 - ab + b^2)

We can set a = x and b = 5:

x^3 + 125 = (x + 5)(x^2 - 5x + 25)

So x^3 + 125 factors as (x + 5)(x^2 - 5x + 25).

a^3 + 64

To factor this expression, we can use the formula for the sum of cubes:

a^3 + b^3 = (a + b)(a^2 + ab + b^2)

We can set a = a and b = 4:

a^3 + 64 = (a + 4)(a^2 + 4a + 16)

So a^3 + 64 factors as (a + 4)(a^2 + 4a + 16).

x^3 - 64

To factor this expression, we can use the formula for the difference of cubes:

a^3 - b^3 = (a - b)(a^2 + ab + b^2)

We can set a = x and b = 4:

x^3 - 64 = (x - 4)(x^2 + 4x + 16)

So x^3 - 64 factors as (x - 4)(x^2 + 4x + 16).

u^3 + 8

To factor this expression, we can use the formula for the sum of cubes:

a^3 + b^3 = (a + b)(a^2 + ab + b^2)

We can set a = u and b = 2:

u^3 + 8 = (u + 2)(u^2 + 2u + 4)

So u^3 + 8 factors as (u + 2)(u^2 + 2u + 4).

On solving the provided question we can say that  Probability of  Red  * Second  Draw Probability of  Red  = \(3 / 10 * 2 / 9 = 6 / 90 = 1 / 15\)

Probability theory, a subfield of mathematics, gauges the likelihood of an occurrence or a claim being true. An event's probability is a number between 0 and 1, where approximately 0 indicates how unlikely the event is to occur and 1 indicates certainty. A probability is a numerical representation of the likelihood or likelihood that a particular event will occur. Alternative ways to express probabilities are as percentages from 0% to 100% or from 0 to 1. the percentage of occurrences in a complete set of equally likely possibilities that result in a certain occurrence compared to the total number of outcomes.

Let the number of  red balls  = x    

\([x / 10] * [ (x - 1) / 9 ] = 1/15 \\x(x - 1) / 90 = 1/15 \\x ( x - 1) = 6 \\x^2 - x - 6 = 0 \\(x -3) ( x + 2) = 0 \\x = 3 or x = -2\)

Angles = 50

Step-by-step explanation:

The angles are alternate interior angles and alternate interior angles are equal

4x+14 = 6x-4

Subtract 4x from each side

4x+14-4x = 6x-4-4x

14 = 2x-4

Add 4 to each side

14+4 = 2x-4+4

18 =2x

Divide by 2

18/2 =2x/2

9 =x

The angles are equal

4x+14 = 6x-4 = 4(9)+14 = 36+14 = 50

Number of students in the group initially is 7.

From the combination formula, C(n, r) = n!/(r!(n - r)!)

Let the number of students are in the group initially be 'n'.

The number of different committees of 4 students from n students is = C(n, 4).

When the number of students in the group increases by 1 then the total number of students becomes = n + 1

The number of different committees of 4 students from (n + 1) students is = C(n + 1, 4).

According to the question, the number of committees in both the cases are equal.

So the equation best suited for the situation is,

2C(n, 4) = C(n + 1, 4)

2n!/(4!(n - 4)!) = (n + 1)!/[4!(n + 1 - 4)!]

2n!/(n - 4)! = (n + 1)!/(n - 3)!

2n(n - 1)(n - 2)(n - 3) = (n + 1)n(n - 1)(n -2)

2(n - 3) = n + 1

2n - 6 = n + 1

2n - n = 6 + 1

n = 7

Hence the number of students are in the group is 7.

Answer:

x = 8

Step-by-step explanation:

In the diagram attached below, the angle marked in blue is equal to 15x, as it is vertically opposite to the angle marked 15x in the question.

Additionally, the blue angle and the angle marked 120° are equal as they are corresponding angles.

Therefore,

\((15x)^{\circ} = 120^{\circ}\)

⇒ \(x = \frac{120^{\circ}}{15^{\circ}}\)      [Dividing both sides of the equation by 15]

⇒ \(x = \bf 8\)

Therefore, the value of x is 8.

One problem with the arithmetic mean is that it is influenced by outliers. Because with the presence of outliers , the arithmetic mean will be pulled towards the outlier. So, the correct option is A) it is influenced by outliers.

The arithmetic mean is calculated by summing up all the observations in a dataset and dividing by the number of observations. While it is a commonly used measure of central tendency, it has some limitations. One of the main problems with the arithmetic mean is that it can be strongly influenced by outliers.

An outlier is an observation that is very different from the other observations in the dataset. When outliers are present, the arithmetic mean can be pulled towards the outlier and may not be a good representation of the typical value in the dataset.  So, the answer is A) it is influenced by outliers.

Step-by-step explanation:

Answer:

1) yes, all of their angles are equal.  (75°, 45°, and 60°)

2) No, their angles are not equal. (42°, 48°, 90°  vs  58°, 32°, 90°)

Step-by-step explanation:

1.

ΔWXY and ΔRST are similar because they have equal angles.

2.

ΔJKM and ΔKLM are not similar because the angles are not equal.

A triangle is a 2-D figure with three sides and three angles.

The sum of the angles is 180 degrees.

We can have an obtuse triangle, an acute triangle, or a right triangle.

We have,

1.

In ΔWXY,

∠X = 75

∠Y = 60

∠W = 180 - (75 + 60) = 180 - 135 = 45

In ΔRST,

∠S = 45

∠R = 60

∠T = 180 - (45 + 60) = 180 - 105 = 75

Now,

We can say that,

ΔWXY and ΔRST are similar because they have equal angles.

2.

In ΔJKM,

∠J = 42

∠M = 45

∠K = 180 - (42 + 45) = 180 - 87 = 93

In ΔKLM,

∠K = 58

∠M = 90

∠L = 180 - (58 + 90) = 180 - 148 = 132

ΔJKM and ΔKLM are not similar because the angles are not equal.

Thus,

ΔWXY and ΔRST are similar because they have equal angles.

ΔJKM and ΔKLM are not similar because the angles are not equal.

Applying the definition of supplementary angles, the measure of angle A is: 47°

The definition of supplementary angles states that two angles are referred to as supplementary angles if they give a sum of 180 degrees when added together.

Given that angle A and angle B are supplementary angles, therefore, based on the definition of supplementary angles, measure of angle A + measure of angle B = 180 degrees.

Measure of angle A = 3x - 10

Measure of angle B = 8x - 19

Substitute

3x - 10 + 8x - 19 = 180

Combine like terms

11x - 29 = 180

11x = 180 + 29

11x = 209

11x/11 = 209/11

x = 19

Measure of angle A = 3x - 10

Plug in the value of x

Measure of angle A = 3(19) - 10

Measure of angle A = 57 - 10

Measure of angle A = 47°

Thus, applying the definition of supplementary angles, the measure of angle A is: 47°
