The regression lines 3x+2y=26 and 6x+y=31 are linear regressions

The mean values are 4 and 7 and the correlation coefficient between x and y is 0.25

The standard deviation of x is 2/13

The mean value and the correlation

We have the equations to be:

3x+2y=26 and 6x+y=31

Make y the subject in the second equation

y = 31 - 6x

Substitute y = 31 - 6x in the first equation

3x+2[31 - 6x] = 26

Expand

3x+ 62 - 12x = 26

Collect like terms

3x - 12x = 26 - 62

Evaluate

-9x = -36

Divide by - 9

x = 4

Substitute x = 4 in y = 31 - 6x

y = 31 - 6 * 4

y = 7

This means that the mean values are 4 and 7

To determine the correlation coefficient, we make y the subject in 3x+2y=26 and x the subject in 6x+y=31.

So, we have:

y = 13 - 3x/2 and x = 31/6 - 1/6y

The above means that:

Bxy = -1/6 and Byx = -3/2

The correlation coefficient is then calculated as:

r^2 = Bxy * Byx

r = -1/6 * -3/2

r = 0.25

Hence, the correlation coefficient between x and y is 0.25

The standard deviation of x

We have:

Var(y) = 4

In (a), we have:

y = 13 - 3x/2

To solve further, we make use of:

Var(y) = Var(ax + b) = a^2Var(x)

This gives

Var(y) = Var(13 - 3x/2) = 13^2 * Var(x)

So, we have:

Var(y) = 13^2 * Var(x)

Substitute 4 for Var(y)

4 = 13^2 * Var(x)

Divide both sides by 13^2

4/13^2 = Var(x)

Express 4 as 2^2

(2/13)^2 = Var(x)

So, we have:

Var(x) = (2/13)^2

Take the square root of both sides

SD(x) = 2/13

Hence, the standard deviation of x is 2/13

The weight of the each pile yesterday would be 6 and 8 pounds.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Given;

Yesterday the ratio of seeds in these piles was 3:4.

Let it be 3x and 4x.

If the 2 pounds of seeds is added in the bigger pile, then it become

4x + 2

He also ate 1/4 pound from the smaller pile, then

3x - 1/4

Now the quantities of seeds in those piles is in the ratio of 5:16.

So, 4x + 2 = 5x

3x - 1/4 = 16x

Solve;

So, 4x + 2 = 5x

2 = 5x - 4x

x = 2

The weight of the each pie would be

3x = 6 pound

4x = 8 pound

Hence, The weight of the each pile yesterday would be 6 and 8 pounds.

The amount of water will remain in the bottle after Cory rides for 2 1/2 hours will be;

What is Equation of line?

The equation of line in point-slope form passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

The average amount of water, in ounces, in his water bottle can be represented by the equation,

⇒ y = - 8x + 32

Where, y is the amount of water remaining after x hours.

Now,

Since, The average amount of water, in ounces, in his water bottle can be represented by the equation,

⇒ y = - 8x + 32

Hence, The amount of water will remain in the bottle after Cory rides for 2 1/2 hours is,

Substitute x = 2 1/2 in above equation,

⇒ y = - 8 × 2 1/2 + 32

⇒ y = - 8 × 5/2 + 32

⇒ y = - 20 + 32

⇒ y = 12 ounces

Thus, The amount of water will remain in the bottle after Cory rides for 2 1/2 hours is,

⇒ y = 12 ounces

Equation of a circle

[tex](x-a)^2+(y-b)^2=r^2[/tex]

where:

Given equation:

[tex]x^2+y^2-6y+1=0[/tex]

Subtract 1 from both sides:

[tex]\implies x^2+y^2-6y=-1[/tex]

To create a trinomial with variable y, add the square of half the coefficient of the y term to both sides:

[tex]\implies x^2+y^2-6y+\left(\dfrac{-6}{2}\right)^2=-1+\left(\dfrac{-6}{2}\right)^2[/tex]

[tex]\implies x^2+y^2-6y+9=8[/tex]

Factor the trinomial with variable y:

[tex]\implies x^2+(y^2-6y+9)=8[/tex]

[tex]\implies x^2+(y-3)^2=8[/tex]

Factor [tex]x^2[/tex] to match the general form for the equation of a circle:

[tex]\implies (x-0)^2+(y-3)^2=8[/tex]

Compare with the general form of the equation for a circle:

[tex]\implies a=0[/tex]

[tex]\implies b=3[/tex]

[tex]\implies r^2=8 \implies r=2\sqrt{2}{[/tex]

Therefore, the center is (0, 3) and the radius is 2√2

Considering the hang time equation, it is found that Player 1 jumped 0.68 feet higher than Player 2.

The hang-time of the ball for a player of jump h is given by:

[tex]t = 2\left(\frac{2h}{32}\right)^{\frac{1}{2}}[/tex]

The expression can be simplified as:

[tex]t = 2\sqrt{\frac{h}{16}}[/tex]

For a player that has a hang time of 0.9s, the jump is found as follows:

[tex]0.9 = 2\sqrt{\frac{h}{16}}[/tex]

[tex]\sqrt{\frac{h}{16}} = \frac{0.9}{2}[/tex]

[tex](\sqrt{\frac{h}{16}})^2 = \left(\frac{0.9}{2}\right)^2[/tex]

[tex]h = 16\left(\frac{0.9}{2}\right)^2[/tex]

h = 3.24 feet.

For a player that has a hang time of 0.8s, the jump is found as follows:

[tex]0.8 = 2\sqrt{\frac{h}{16}}[/tex]

[tex]\sqrt{\frac{h}{16}} = \frac{0.8}{2}[/tex]

[tex](\sqrt{\frac{h}{16}})^2 = \left(\frac{0.8}{2}\right)^2[/tex]

[tex]h = 16\left(\frac{0.8}{2}\right)^2[/tex]

h = 2.56 feet.

The difference is given by:

3.24 - 2.56 = 0.68 feet.

The distances in feet covered in 4 steps, 6 steps, 12 steps, and 30 steps are 10 feet, 15 feet, 30 feet and 75 feet.

When you walk with a normal stride, the average distance covered in 2 steps is about 5 feet

From the question, we have:

Rate = 5 feet per 2 steps

This gives

Rate = 5/2 feet per step

So, we have:

Rate = 2.5 feet per step

The distance is then calculated as:

Distance = Rate * Steps

This gives

Distance = 2.5 * Steps

So, the distances in feet covered in 4 steps, 6 steps, 12 steps, and 30 steps are

Distance = 2.5 * 4 = 10 feet

Distance = 2.5 * 6 = 15 feet

Distance = 2.5 * 12 = 30 feet

Distance = 2.5 * 30 = 75 feet

Hence, the distances in feet covered in 4 steps, 6 steps, 12 steps, and 30 steps are 10 feet, 15 feet, 30 feet and 75 feet.

[tex]\mu = 100 * 82\%[/tex]

[tex]\mu = 82[/tex]

Calculate the standard deviation:

[tex]\sigma = \sqrt{\mu(1 - p)[/tex]

[tex]\sigma = \sqrt{82 * (1 - 82\%)[/tex]

[tex]\sigma = 3.84[/tex]

Within ± 0.02 of the population proportion are:

[tex]x_{min} = 82 * (1 - 0.02) = 80.38[/tex]

[tex]x_{max} = 82 * (1 + 0.02) = 83.64[/tex]

Calculate the z-scores at these points using:

[tex]z = \frac{x - \mu}{\sigma}[/tex]

So, we have:

[tex]z_1 = \frac{80.36 - 82}{3.84} = -0.43[/tex]

[tex]z_2 = \frac{83.64 - 82}{3.84} = 0.43[/tex]

The probability is then represented as:

P(x ± 0.02) = P(-0.43 < z < 0.43)
