In regression analysis, Y' represents the predicted scores or values of the dependent variable Y based on the independent variables.

The regression model aims to find the best-fitting line or curve that estimates the relationship between the independent variables and the dependent variable. The predicted scores, denoted as Y', are calculated using the regression equation and the values of the independent variables.

These predicted scores represent the expected values of the dependent variable based on the given independent variable values. They are the estimated values obtained from the regression model and are used for making predictions and assessing the relationship between the variables. Therefore, Y' is associated with the predicted scores in regression analysis.

Irs a little hard to see.  But Dilation means the size of the object changed ( increase or decrease) but the shape stays exactly same

The graph that shows a dilation among the given graphs is; Graph B.

Dilation in graphs simply means each side is multiplied by the same scale factor. What this means is that the ratio of each dilated side to their respective old sides before dilation must be the same scale factor.

Here, we have,

We can see that the pre-dilated image has 2 units along the y - axis and 3 units across the x-axis.

After dilation, it now has 4 units along the y - axis and 6 units across the x-axis.

This means the scale factor in both axis are; 4/2 = 2 and 6/3 = 2.

They are both the same scale factors and as such this graph shows a dilation.

Step-by-step explanation:

The inner product of two vectors A = (2, -3,0) and B = (-1,0,5) is -2 / √(13×26).

Solving the given system of equations using Gaussian elimination:

2x + 3y + z = 2 y + 5z = 20 -x+2y+3z = 13

Matrix form of the system is

[A] = [B] 2 3 1 | 2 0 5 | 20 -1 2 3 | 13

Divide row 1 by 2 and replace row 1 by the new row 1: 1 3/2 1/2 | 1

Divide row 2 by 5 and replace row 2 by the new row 2: 0 1 1 | 4

Divide row 3 by -1 and replace row 3 by the new row 3: 0 0 1 | 5

Back substitution, replace z = 5 into second equation to solve for y, y + 5(5) = 20 y = -5

Back substitution, replace z = 5 and y = -5 into the first equation to solve for x, 2x + 3(-5) + 5 = 2 2x - 15 + 5 = 2 2x = 12 x = 6

The solution is (x,y,z) = (6,-5,5)

Therefore, the solution to the given system of equations using Gaussian elimination is (x,y,z) = (6,-5,5).

The given two vectors are A = (2, -3,0) and B = = (-1,0,5). The inner product of two vectors A and B is given by

A·B = |A||B|cosθ

Given,A = (2, -3,0) and B = (-1,0,5)

Magnitude of A is |A| = √(2²+(-3)²+0²) = √13

Magnitude of B is |B| = √((-1)²+0²+5²) = √26

Dot product of A and B is A·B = 2(-1) + (-3)(0) + 0(5) = -2

Cosine of the angle between A and B is

cosθ = A·B / (|A||B|)

cosθ = -2 / (√13×√26)

cosθ = -2 / √(13×26)

To determine whether the series ∑(n=1 to infinity) 7n/n is convergent or divergent, we can apply the ratio test. The ratio test helps us determine the convergence or divergence of a series by examining the limit of the ratio of consecutive terms.

In this case, let's calculate the ratio of consecutive terms using the formula for the ratio test:

lim(n→∞) |(7(n+1)/(n+1))/((7n/n)|

Simplifying the expression, we get:

lim(n→∞) |7(n+1)/n|

As n approaches infinity, the limit evaluates to:

lim(n→∞) |7(n+1)/n| = 7

Since the limit is a finite positive value (7), which is less than 1, the ratio test tells us that the series is convergent.

However, you mentioned identifying an (term) in the series, and it seems there may be an incomplete part of the question. Please provide additional information or clarification about identifying an term in the series so that I can provide a more specific answer.

Answer: The answer is 65.5%

Step-by-step explanation: I hope it helps you!

Angles p and q are complementary, which means that their sum is equal to 90 degrees. Let's assume the size of angle q is x degrees. Since p is four times the size of q, we can write the equation p = 4q.

To find the size of q, we need to substitute the value of p in terms of q into the equation for the sum of the angles: p + q = 90.

Substituting 4q for p, we get:

4q + q = 90

Combining like terms:

5q = 90

To solve for q, we divide both sides of the equation by 5:

q = 90/5

Simplifying:

q = 18

Therefore, the size of angle q is 18 degrees.

when angles p and q are complementary and p is four times the size of q, the size of angle q is 18 degrees.

The faster cyclist's speed is 46 km/hr and the slower cyclist's speed is 36 km/hr.

Let the speed of the faster cyclist be x km/hr. Then the speed of the slower cyclist is x-10 km/hr.
As they are travelling towards each other, their relative speed will be the sum of their speeds. So,
Relative speed = x + (x-10) = 2x - 10 km/hr
Time taken to meet = 5 hours
Distance travelled = relative speed x time taken
210 = (2x-10) x 5
Solving for x, we get x = 46 km/hr (approx.)
Therefore, the faster cyclist's speed is 46 km/hr and the slower cyclist's speed is 36 km/hr.

To solve this problem, we need to use the formula Distance = Speed x Time. Since the two cyclists are travelling towards each other, we need to find their relative speed by adding their speeds. Then we can use the distance and time given to calculate their speeds individually using the formula Speed = Distance / Time.

The faster cyclist is travelling at a speed of 46 km/hr, while the slower cyclist is travelling at a speed of 36 km/hr.

The scale factor of 10cm to 5m is 50.

The scale factor is a measure for similar figures, who look the same but have different scales or measures.

For example ,if a length of 5cm is doubled and it gives a length 10cm, the scale factor is 10/5 = 2. This means that we can express scale factor with a formula;

scale factor = new dimension / old dimension

Here, the old dimension is 10cm and the new dimension is 5m. We need to convert the 5m into cm

therefore 5m = 5× 100 = 500cm

therefore scale factor = 500/10 = 50

Step-by-step explanation:

The rate at which the area of the triangle is increasing when the angle between the sides of fixed lengths is π/3 is 0.3 m²/s.

If the lengths a and b for two sides of the triangle, as well as the included angle θ, are known, the area of a triangle can be calculated using the sine formula.

\(\text { Area }=\frac{1}{2} a b \sin \theta\)

Now, according to the question;

The two sides of the triangle are given;

Let a = 4m and b = 5m.

Let θ = π/3. be the angle between the two sides;

Then,

Differentiate the area with respect to time (as rate of change of area)

\(\begin{aligned}\frac{\mathrm{d} A}{\mathrm{~d} t}=\frac{\mathrm{d}}{\mathrm{d} t} \frac{1}{2} a b \sin \theta &=\frac{1}{2} * 4 * 5 * \frac{\mathrm{d}(\sin \theta)}{\mathrm{d} \theta} \cdot \frac{\mathrm{d} \theta}{\mathrm{d} t} \\&=10 *(\cos \theta) * 0.06 \frac{\mathrm{m}^{2}}{\mathrm{~s}}=0.6 \cos (\pi / 3) \frac{\mathrm{m}^{2}}{\mathrm{~s}} \\&=0.6 * 0.5 \frac{\mathrm{m}^{2}}{\mathrm{~s}}=0.3 \frac{\mathrm{m}^{2}}{\mathrm{~s}}\end{aligned}\)
