Answer:

6 and 10

Step-by-step explanation:

first find what 1 min is in meters

1/3 is 8 so 8x3 = 1m which is 24

now divide based on the next two numbers

1/4 of 24 = 6

6x 1 = 6

now the next

24/12 = 2

2x5 = 10

these two results, 6 and 10, are the answers to the missing meter values

√12x12x3

→ 12√3

Therefore, the answer is 12√3.

As similarity theorem, the value of x that will make the triangles similar by SSS similarity theorem is 77.

Similarity theorem:

In math, similarity theorem refers the line segment splits two sides of a triangle into proportional segments if and only if the segment is parallel to the triangle's third side.

Given,

Here we need to find the t value of will make the triangles similar by the similarity theorem.

For example, we are told that the 2 triangles are similar by SSS theorem.

Here we know that, SSS means Side - Side -Side and it is a congruence theorem which states that the 3 corresponding sides of two triangles have same ratio, then we can say that the two triangles are congruent by SSS theorem

Therefore, in the triangles ,applying the SSS postulate gives;

=> x/35 = 44/20

Then by applying the multiplication property of equality, let us multiply both sides by 35 to get;

=> x = (44 * 35)/20

When we simplify this one then we get,

=> x = 77

Therefore, the value of x is 77.

Answer: y=(x-7)(x+3)

Step-by-step explanation:

The equation given is \(y=2x^2-8x-42\) Notice that 2 is a common factor, so we can divide each term by 2.

\(y=x^2-4x-21\)          [factor]

\(y=(x-7)(x+3)\)

If we distribute the factored form above, we get the same equation. Therefore, y=(x-7)(x+3) is the factored form.

Answer:

-6

Step-by-step explanation:

The average rate of change of a function, f(x), on interval [a,b] is (f(b)-f(a))/(b-a).

So the avereage rate of change of a function, f(x)=x^2+5x+1, on [-9,-2] is

(f(-2)-f(-9))/(-2--9)

(f(-2)-f(-9))/(7)

Stop!

To find f(-2), you replace x in f(x) = x^2 + 5x + 1, with (-2) giving you f(-2)=(-2)^2+5(-2)+1=4-10+1=-6+1=-5.

To find f(-9), you replace x in f(x) = x^2 + 5x + 1, with (-9) giving you f(-2)=(-9)^2+5(-9)+1=81-45+1=36+1=37.

Answer:

A = 540 m²

Step-by-step explanation:

consider the shape split into 3 rectangles

the length is divided into 3 congruent sections

single dash = 30 m ÷ 3 = 10 m

the width is divided into 3 congruent sections

double dash = 27 m ÷ 3 = 9 m

then area (A) is the total of the 3 rectangular areas

A of left rectangle = 10 × 9 = 90 m²

A of middle rectangle = 10 × (9 + 9) = 10 × 18 = 180 m²

A of right rectangle = 10 × 27 = 270 m²

total area = 90 + 180 + 270 = 540 m²

The  probability that between 78% and 86% were non-teacher workers from private schools is 0.7689

Eighty-four percent of non-teacher workers were employed in private schools.

p = 0.84

q = 1 - p = 1 - 0.84 = 0.16

if a random sample of 200 non-teacher workers from private schools was selected

We need to find the  probability that between 78% and 86% were non-teacher workers from private schools.

n = 200

μρ = 0.84

αp = √(p(1 - p)/n) = √(0.84(0.16)/200) = 0.026

P(0.78 < P < 0.86) = P((0.78 - 0.84)/0.026 < (p - μp)/σp < (0.86 - 0.84)/0.026)

= P(-2.31 < z < 0.77)

= P(z < 0.77) - P(z < -2.31)

using z table

0.7794 - 0.0103

= 0.7689

In this question, we are given specific values for U and V and asked to express the given expression in terms of those values.

To simplify the expression using the given values, we substitute \(U = 3x^3\)and V = y + 1 into the original expression:

\(81x^6 - (y + 1)^2\)

Replacing U and V:

\(81(3x^3)^2 - (V)^2\)

Simplifying:

The new image would be smaller in sample size than the original image.

For example, if the scale factor is 0.5, the new image will be half the size of the original image. To determine the exact size of the new image, the scale factor is multiplied with the width and height of the original image. For example, if the original image is 200 x 100 pixels, and the scale factor is 0.5, the new image will be

(200 x 0.5) = 100 x (100 x 0.5)

= 50 pixels.

The same concept applies when the scale factor is a decimal. For example, if the scale factor is 0.75, the new image will be three-quarters the size of the original image. In this case, the new image would be

(200 x 0.75) = 150 x (100 x 0.75)

= 75 pixels.

In summary, when the scale factor is less than 1, the new image will always be smaller than the original image, depending on the scale factor. The exact size of the new image can be determined by multiplying the width and height of the original image with the scale factor.

A result is called "statistically significant" when the p-value is less than the significant level, typically 0.05.

This means that there is less than a 5% chance that the results are due to chance alone, and suggests that there is a real effect present in the data.

The Null Hypothesis is the assumption that there is no significant difference between the measured phenomenon and a certain value or set of values. A statistically significant result means that the observed data are inconsistent with the assumption of no difference, or no effect.

The descent directions for the function at the point (0,0) are given by the vectors (d₁, d₂) where d₁ > 0.

To find all the descent directions of the function f(x₁, x₂) = 100(x₂ - x₁²)² + (1 - x₁)² at the point (0,0), we need to compute the gradient of the function at that point and then find the directions in which the gradient vector points downward.

Step 1: Compute the gradient of the function:

∇f(x₁, x₂) = (∂f/∂x₁, ∂f/∂x₂)

∂f/∂x₁ = -400x₁(x₂ - x₁²) - 2(1 - x₁)

∂f/∂x₂ = 200(x₂ - x₁²)

Therefore, the gradient of f(x₁, x₂) is:

∇f(x₁, x₂) = (-400x₁(x₂ - x₁²) - 2(1 - x₁), 200(x₂ - x₁²))

Step 2: Evaluate the gradient at the point (0,0):

∇f(0, 0) = (-2, 0)

Step 3: Determine the descent directions:

A descent direction is a vector in which the function decreases. In this case, it means the dot product between the gradient vector and the descent direction vector should be negative.

Let's consider a general descent direction vector (d₁, d₂), then the condition for it to be a descent direction is:

∇f(0, 0) · (d₁, d₂) < 0

Substituting the values of ∇f(0, 0), we have:

(-2, 0) · (d₁, d₂) < 0

-2d₁ < 0

Therefore, the descent directions for the function at the point (0,0) are given by the vectors (d₁, d₂) where d₁ > 0.

In summary, the descent directions for the function f(x₁, x₂) = 100(x₂ - x₁²)² + (1 - x₁)² at the point (0,0) are vectors (d₁, d₂) where d₁ > 0.

The probability that Radesh is late on less than 3 days in a 6 day week is 0.7865.

To calculate the probability that Radesh is late on less than 3 days in a 6 day week,

Use the binomial distribution formula

P(X<3) = Σ (i=0 to 2) \(^{6} C_i\) \(0.35^i 0.65^{(6-i)\)

Here,

\(^{6} C_i\) is the number of ways to choose i days out of 6,

\(0.35^i\) is the probability that Radesh is late on i days,

And \(0.65^{(6-i)\) is the probability that he is on time on the remaining (6-i) days.

Now, Solve this equation:

⇒ P(X<3) = \(^{6} C_0\) 0.35 x 0.65 + \(^{6} C_1\) 0.35 x 0.65 + \(^{6} C_2\) 0.35 x 0.65

⇒ P(X<3) = 0.7865

Investment X earns the greater amount of interest over a period of 2 years.

Simple interest is a method of calculating interest on an amount for n period of time with a rate of interest of r. It is calculated with the help of the formula,

SI = PRT

where SI is the simple interest, P is the principal amount, R is the rate of interest, and T is the time period.

Let's consider that Ian invests in X, then:

Principle amount, P = $6,000
Time, T = 2 Years

Rate of Interest, R = 4.5% at simple Interest = 0.045

The interest earned is:

Interest = PRT = $6,000 × 0.045 × 2 = $540

Now, consider that Ian invests in Y, then:

Principle amount, P = $6,000
Time, n = 2 Years

Rate of Interest, R = 4% at Compound Interest = 0.04

The interest earned is:

Interest = P(1+R)ⁿ - P

            = $6,000(1+0.04)² - $6,000

When a planet orbits a star, it causes a slight change in the brightness or light intensity of the star. This is known as the transit method of planet detection. As the planet passes in front of the star from our line of sight, it blocks a small portion of the star's light, causing a temporary decrease in its brightness. By carefully measuring these changes in brightness over time, scientists can infer the presence and characteristics of planets orbiting the star.
