Answer:

a) 12 · y = x

b) If the points show equivalent fractions and the line goes through (0,0)

Step-by-step explanation:

a1) divide any numbers from the x and y line (for example, 2 ÷ 24 would give us 12)

a2) This equation makes sense because any number from the x line (for example, 2) multiplied by 12 would give us the number from the y line (in this example, 24).

The decimal numbers that have an even number in the tenths place, an odd number in the hundredths place, and a prime number in the thousandths place include 0.237, 0.893, 0.475, and 0.652.

An even number is any number that can be divided exactly by two. Even numbers always have a last digit of 0, 2, 4, 6, or 8. Even numbers include 2, 4, 6, 8, 10, 12, 14, and 16.

Odd numbers are those that cannot be divided evenly by two. It cannot be evenly divided into two separate integers. When we divide an odd number by 2, we get a remainder. Odd numbers include 1, 3, 5, 7, and so on.

A prime number is a natural number greater than one that cannot be calculated as the product of two smaller natural numbers. A composite number is a natural number greater than one that is not prime. 5 is prime, for example, because the only ways to write it as a product, 1 5 or 5 1, involve 5 itself.

A prime number is a whole number greater than one with only the number one and itself as factors. A factor is a whole number that can be divided into other numbers evenly.

In this case, 0.237, 0.893, 0.475, and 0.652 have an even number in the tenths place which is the first place after the decimal point. Also, there's an odd number in the hundredths place, and a prime number in the thousandths place.

The p-value when the test statistic is equal to 2.30 is 0.033.

A statistical measurement known as a p-value is employed to check a hypothesis' validity against actual data.

A p-value calculates the likelihood of getting the outcomes that were observed, presuming that the null hypothesis is correct.

The statistical significance of the difference that was found increases with decreasing p-value.

The p-value, used in null-hypothesis significance testing, represents the likelihood that the test findings will be at least as extreme as the result actually observed, assuming that the null hypothesis is true.

So, the p-value will be:

The t-value for (n-1 = 20-1 = 19) degrees of freedom serves as the test statistic in this experiment.

Using the formula: T.DIST.2T(2.3,19)

As given in the question,

Sample size 'n' = 60

h(-14) means to substitute x = -14 into function h(x).

Answer:

  4) ∠J = ∠L = 88°; ∠K = 92°

  5) ∠P = ∠R = 34°; ∠S = 146°

  6) ∠T = 54°; ∠U = ∠W = 126°

Step-by-step explanation:

You want the remaining angles in each rhombus where one angle is specified.

In a rhombus, as in any parallelogram, opposite angles are congruent, and adjacent angles are supplementary.

In each of the rhombi, the adjacent angle is supplementary:

  4) 180° -92° = 88°

  5) 180° -146° = 34°

  6) 180° -54° = 126°

Then the angle measures of interest are ...

  4) ∠J = ∠L = 88°; ∠K = 92°

  5) ∠P = ∠R = 34°; ∠S = 146°

  6) ∠T = 54°; ∠U = ∠W = 126°

The kiwi as per the given relation of ostrich and kiwi's height is equal to 22inches tall.

As given in the question,

Ostrich height is equal to 108 inches

Let us consider 'x' inches be the height of the kiwi.

Ostrich is 20inches more than four times of x.

Ostrich height  = 20 + 4x

⇒ 108 = 20 + 4x

Subtract 20 from both the sides we get,

108 - 20 = 20 + 4x -20

⇒ 88 = 4x

Divide by 4 on both the sides we get,

88/ 4 = 4x / 4

⇒ x = 22 inches

Therefore, as per the given relation of ostrich and kiwi's height , kiwi is 22inches tall.

Given:

There are 5 marbles in a bag. Each marble is a different color. The colors are: red, orange, green, blue, purple. Two marbles are randomly drawn from the bag without replacement.

We need to determined the probability that the red marble is drawn first and the white marble is drawn second.

According to the question,

It is given that, there are 5 different marbles. In the first draw, you have a one out of 5 chance of getting the red is 1/5 .

In the second draw, there are 4 marbles remaining, so a one out of 4 chance of drawing a white marble i.e. 1/4.

Now, calculating the total probability of drawing the red and then white marble, we multiply the probabilities if each draw.

The width of the rectangle, x is 2.76 cm

Given,

Here,

Area of rectangle = length × width

Then,

17.6 = 2.3x²

x² = 17.6/2.3

x² = 7.65

x = √7.65

What do you mean by adjacent?

Adjacent refers to something that is close to or nearby. Your next-door neighbor is the person who lives in the home or apartment that is next to yours, even though you may consider the individuals who live up and down your street to be your neighbor.

Two things can be considered adjacent if they contact each other or share a wall or border. If two angles in geometry share a side and a vertex, they are said to be adjacent. In other words, neighbor angles do not overlap and are adjacent to each other immediately.

Solution Explained:

So according to the question, we get the equation

Perimeter is 4x + 3y = 720

⇒ x = 180 - [tex]\frac{3}{4}y[/tex]

Taking Area = 2xy

= 2(180 - [tex]\frac{3}{4} y[/tex])y

= 360y - [tex]\frac{3}{2} y^{2}[/tex]

Differentiating the function w.r.t y

A'(y) = 360-3y

Setting to 0

0 = 360 - 3y

⇒ y = 360 / 3 ⇒ 120

Now putting the value of y in

x =  [tex]180- \frac{3}{4} X 120[/tex]

x = 180 - 90 = 90

Step-by-step explanation:

Arithmetic sequences are sequences that change by a constant factor.

Explicit Rule

The formula that describes an arithmetic sequence is called the "explicit rule". This formula is f(x) = f(1) + d(x-1). Sometimes the rule will be written with [tex]a_{n}[/tex] instead of f(x) but the equations are still the same.

In this equation, f(1) is the first term of the sequence, d is the common difference, and x is the term. The common difference is the factor that the sequence changes by.

Setting Up the Equation

To set up the equation, we need to find f(1) and d.

The first term, f(1), is directly given to us in the equation. The first term written is -6, so f(1)=-6.

It is slightly more difficult to find d. But, one easy way to find d is by subtracting terms. Take the second term, 5, and subtract the first term, -6.

So, d = 11. Each term in the sequence increases by 11.

The final equation is f(x) = -6 + 11(x-1).

Finding the 70th Term

Now, all we have to do is plug 70 in for x. To find any term in the sequence, all you have to do is plug the term number in for x.

The 70th term in the sequence is 753.

A vector is a quantity or phenomenon that has two independent properties: magnitude and direction. The term also denotes the mathematical or geometrical representation of such a quantity.

Examples of vectors in nature are velocity, momentum, force, electromagnetic fields, and weight. A quantity or phenomenon that exhibits magnitude only, with no specific direction, is called a Scalar . Examples of scalars include speed, mass, electrical resistance, and hard-drive storage capacity.

Scalar multiplication is the multiplication of a vector by a scalar (where the product is a vector), and is to be distinguished from inner product of two vectors (where the product is a scalar).

For quaternion scalars and matrices:

λ = 2     A = [tex]\left[\begin{array}{ccc}a&b\\c&d\\\end{array}\right][/tex]
