Answer:

2/3, 3/7, 2/5.

Step-by-step explanation:

The easiest way to tell which number is larger is by using a common denominator. For example, when comparing 2/3 and 3/7, the common denominator would be 21. I multiplied 3 by 7 to get 21, and multiplied 7 by 3 to get 21. Therefore, we must multiply the  numerator by the same number. Then, our two numbers are 14/21, and 9/21. Now, we can easily see that 2/3 (14/21) is the bigger fraction.

Example Math:

2/3·1/7 = 2/21

2/21·7 = 14/21

3/7·1/3 = 3/21

3/7·3 = 9/21

The measures of the angles are ∠1 = 127°, ∠2 = 53°, ∠3 = 127°, ∠4 = 37°, ∠5 = 53°, ∠6 = 90°, ∠7 = 37°, ∠8 = 143°, ∠9 = 37° and ∠10 = 143°

From the question, we have the following parameters that can be used in our computation:

The transversal lines and the other lines

So, we have

∠1 = 180 - 53

Evaluate

∠1 = 127°

Also, we have

∠5 = 53°

By vertical angles, we have

∠2 = 53°

∠3 = 127°

Next, we have

∠4 = 127 - 90°

∠4 = 37°

Solving further, we have

∠6 = 90°

By corresponding angles, we have

∠7 = 37°

∠9 = 180 - 90 - 53°

∠9 = 37°

∠10 = 90 + 53°

∠10 = 143°

∠8 = 143°

Answer:

Step-by-step explanation:

y = ¼x + (-7/4) is the standard form for the line that passes through (3, −1) and (−5, −3)

What is Slope intercept form?

y=mx=c is the slope intercept form of a line, m is the slope.

We need to find equation of line passing through (3, −1) and (−5, −3)

First we need to calculate slope 'm'.

slope m = y2- y1 / x2-x1

y2=-3, y1=-1, x2=-5, x1=3

m= -3 - (-1)/(-5)-3 = -2/-8=1/4

Equation of line, y=mx+c

find C in the equation (y=mx+c)

C = y-mx

C = -1-1/4(3)= -7/4

now replace the values you find in the equation (y=Mx+C)

y =1/4x-7/4

Hence y =1/4x-7/4 is the equation of line  passes through (3, −1) and (−5, −3).

Answer:

Step-by-step explanation:

You multiply each coordinate by the scale factor of 1/4

B  (6 x \(\frac{1}{4}\)) = 1.5 (9 × \(\frac{1}{4}\)) = 2.25 so B becomes B'(1.5, 2.25)

Doing the same with C and D

C' ( 2.25, 2.25)

D' ( .75, - 1.5)

The probability that it lands heads at least once is 1.0720.

Probability is the measure of the likelihood of an event occurring. In this case, we are looking at the probability of a coin landing heads at least once after three tosses.

Let's denote the event of the coin landing heads on the first toss as event A, the event of the coin landing heads on the second toss as event B, and the event of the coin landing heads on the third toss as event C.

The probability of landing heads at least once is equal to the sum of the probabilities of each individual event occurring (A, B, or C) minus the probability of all three events occurring (A and B and C).

P(A or B or C) = P(A) + P(B) + P(C) - P(A and B and C)

Since the coin is unfair and has a probability of 0.4 of landing heads, P(A) = P(B) = P(C) = 0.4.

Using the formula for the probability of multiple events happening simultaneously, we find that P(A and B and C) = P(A) * P(B) * P(C) = 0.4 * 0.4 * 0.4 = 0.064.

Plugging in all the values, we get:

P(A or B or C) = 0.4 + 0.4 + 0.4 - 0.064 = 1.136 - 0.064 = 1.072

Rounding to four decimal places, the answer is 1.0720, which means that the probability of the coin landing heads at least once after three tosses is 1.0720.

Step-by-step explanation:

equation so I could try to solve it

The direction conjugate to the vector (1,-2,0) relative to the conic section at the point .

To find the direction conjugated to a given vector relative to a conic section, we can use the fact that the gradient of the conic section at a point is perpendicular to the tangent plane at that point. Therefore, if we find the gradient of the conic section at a point and take the dot product with the given vector, we will obtain the direction conjugate to the given vector at that point.

First, we need to find the equation of the tangent plane to the conic section at a point on the surface. We can use the formula for the gradient of a function to find the normal vector to the tangent plane:

[\nabla f = \begin{pmatrix} \frac{\partial f}{\partial x} \ \frac{\partial f}{\partial y} \ \frac{\partial f}{\partial z} \end{pmatrix}]

where (f(x,y,z) = x^2+2xy-y^2-4xz+2yz-2z^2).

Taking partial derivatives of (f) with respect to (x), (y), and (z), we get:

[\begin{aligned}

\frac{\partial f}{\partial x} &= 2x+2y-4z \

\frac{\partial f}{\partial y} &= 2x-2y+2z \

\frac{\partial f}{\partial z} &= -4x+2y-4z

\end{aligned}]

Therefore, the gradient of (f) is:

[\nabla f = \begin{pmatrix} 2x+2y-4z \ 2x-2y+2z \ -4x+2y-4z \end{pmatrix}]

Next, we need to find a point on the conic section at which to evaluate the gradient. One way to do this is to solve for one of the variables in terms of the other two and then substitute into the equation of the conic section to obtain a two-variable equation. We can then use this equation to find points on the conic section.

From the equation of the conic section, we can solve for (z) in terms of (x) and (y):

[z = \frac{x^2+2xy-y^2}{4x-2y}]

Substituting this expression for (z) into the equation of the conic section, we get:

[x^2+2xy-y^2-4x\left(\frac{x^2+2xy-y^2}{4x-2y}\right)+2y\left(\frac{x^2+2xy-y^2}{4x-2y}\right)-2\left(\frac{x^2+2xy-y^2}{4x-2y}\right)^2 = 0]

Simplifying this equation, we obtain:

[x^3-3x^2y+3xy^2-y^3 = 0]

This equation represents a family of lines passing through the origin. To find a specific point on the conic section, we can choose values for two of the variables (such as setting (x=1) and (y=1)) and then solve for the third variable. For example, if we set (x=1) and (y=1), we get:

[z = \frac{1^2+2(1)(1)-1^2}{4(1)-2(1)} = \frac{1}{2}]

Therefore, the point (1,1,1/2) lies on the conic section.

To find the direction conjugate to the vector (1,-2,0) relative to the conic section at this point, we need to take the dot product of (1,-2,0) with the gradient of (f) evaluated at (1,1,1/2):

[\begin{pmatrix} 1 \ -2 \ 0 \end{pmatrix} \cdot \begin{pmatrix} 2(1)+2(1)-4\left(\frac{1}{2}\right) \ 2(1)-2(1)+2\left(\frac{1}{2}\right) \ -4(1)+2(1)-4\left(\frac{1}{2}\right) \end{pmatrix} = \begin{pmatrix} 1 \ -2 \ 0 \end{pmatrix} \cdot \begin{pmatrix} 2 \ 2 \ -4 \end{pmatrix} = -8]

We determine the cumulative weight retained at each sieve and then calculate the cumulative percentage passing by dividing the cumulative weight passing by the total weight of the sample and multiplying by 100.

To calculate the percentage passing for each sieve size in a sieve analysis, we need to determine the cumulative percentage passing at each sieve size.

The sieve analysis provides information about the particle size distribution of an aggregate sample. It involves passing the sample through a series of sieves with different mesh sizes, and measuring the amount of material retained on each sieve.

To calculate the percentage passing, we first need to determine the cumulative weight retained at each sieve size. This is done by subtracting the weight retained on a particular sieve from the weight retained on the previous sieve.

Once we have the cumulative weight retained, we can calculate the cumulative percentage passing by dividing the cumulative weight passing by the total weight of the sample and multiplying by 100.

Here is an example:

Sieve Size (mm) | Weight Retained (g)

4.75 | 50

2.36 | 30

1.18 | 20

0.6 | 15

0.3 | 10

0.15 | 5

To calculate the cumulative percentage passing:

Calculate the cumulative weight retained:

Cumulative weight retained at sieve 4.75 mm = 50 g

Cumulative weight retained at sieve 2.36 mm = 50 g + 30 g = 80 g

Cumulative weight retained at sieve 1.18 mm = 80 g + 20 g = 100 g

Cumulative weight retained at sieve 0.6 mm = 100 g + 15 g = 115 g

Cumulative weight retained at sieve 0.3 mm = 115 g + 10 g = 125 g

Cumulative weight retained at sieve 0.15 mm = 125 g + 5 g = 130 g

Calculate the cumulative percentage passing:

Cumulative percentage passing at sieve 4.75 mm = (Total weight - Cumulative weight retained) / Total weight * 100 = (130 g - 50 g) / 130 g * 100 = 61.54%

Cumulative percentage passing at sieve 2.36 mm = (130 g - 80 g) / 130 g * 100 = 38.46%

Cumulative percentage passing at sieve 1.18 mm = (130 g - 100 g) / 130 g * 100 = 23.08%

Cumulative percentage passing at sieve 0.6 mm = (130 g - 115 g) / 130 g * 100 = 11.54%

Cumulative percentage passing at sieve 0.3 mm = (130 g - 125 g) / 130 g * 100 = 3.85%

Cumulative percentage passing at sieve 0.15 mm = (130 g - 130 g) / 130 g * 100 = 0%

The limitation of cross-sectional research among the given choices is: Differences between age groups may be due to different experiences.

Explanation:

The limitation of cross-sectional research is that differences between age groups may be due to different experiences. Cross-sectional research is a type of observational study design that collects data at a single point in time from a sample of individuals of different ages, groups, or populations. This type of research is used to study differences between groups, such as age, gender, or socioeconomic status.

However, one of the main limitations of cross-sectional research is that the differences observed between groups may not necessarily be due to age or any other factor of interest, but rather due to different experiences, histories, or social contexts. For instance, if researchers find that older adults perform worse on a cognitive test than younger adults, it is unclear whether this difference is due to age-related decline, or to factors such as education, occupation, or health.

Other limitations of cross-sectional research include the inability to establish causal relationships between variables, the possibility of selection bias or confounding, and the inability to track changes over time. Additionally, the other options presented in the multiple-choice question, such as test-wise effects, drop-out rates, and questionnaire completion by children, are not specific limitations of cross-sectional research, but rather potential issues that may affect any type of research design.

Therefore, the limitation of cross-sectional research is that differences between age groups may be due to different experiences.

collecting like terms

7x -4x = 13+19-2

3x = 30

divide both sides by 3

x = 30/3

x = 10

Answer:

The value of a₁₀ is -1352

Step-by-step explanation:

a₂ = -8

a₅ = -512

Now,

a₂ = -8 can be written as

a + d = -8 ...(1) and

a₅ = -512 can be written as

a + 4d = -512 ...(2)

Now, from equation (2) we get,

a + 4d = - 512

a + d + 3d = - 512

(-8) + 3d = - 512 (.°. a + d = -8)

3d = - 512 + 8

3d = - 504

d = - 504 ÷ 3

d = - 168

Now, for the value of a put the value of d = -168 in equation (1)

a + d = -8

a + (-168) = -8

a - 168 = -8

a = 168 - 8

a = 160

Now, For a₁₀

a₁₀ = a + 9d

a₁₀ = 160 + 9(-168)

a₁₀ = 160 - 1512

a₁₀ = -1352

Thus, The value of a₁₀ is -1352

Answer:

y > 19x - 2

Step-by-Step Explanation:

Slope-intercept form is y = mx + b. In this case it is y > mx + b.

2 is our b and 19x is our mx.

We need to put the y on one side and the other terms on the other side of greater than sign. When we switch which term the side is on, we have to change the operation. If it is a negative number it turns positive and vice-versa. Our y can't be negative so we need to put it on the right side to change it to a positive.

19x > y + 2

Now we need to get the 2 on the same side as the 19x. So we bring it to the other side and switch the operation.

19x - 2 > y

Now we are just going to flip both sides to get the y on the left and the 19x - 2 on the right.

y > 19x - 2

Manipulating temperature in a room to study its impact on task performance involves categorizing the various temperature conditions as the "levels" of the variable.

In experimental research, when investigating the influence of temperature on task performance, researchers manipulate and control the temperature to create different conditions or levels. These temperature levels serve as the independent variable in the study. By systematically altering the temperature, researchers can observe and analyze how variations in temperature affect participants' performance on the given tasks. This experimental design allows researchers to identify patterns, trends, and potential causal relationships between temperature and task performance. Understanding the different temperature conditions or levels in such studies helps researchers learn about the nuanced impact of temperature on human performance and potentially inform practical applications in various settings, such as optimizing work environments or designing effective learning spaces.
