The mean of a sampling distribution of mean is equal to the population mean.

The mean of a sampling distribution of the mean is equal to the population mean. This is a fundamental property of sampling distributions. When repeatedly taking random samples from a population and calculating the mean of each sample, the distribution of those sample means will have a mean that is equal to the population mean. This is known as the central limit theorem, which states that as the sample size increases, the sampling distribution of the mean approaches a normal distribution centered around the population mean. Therefore, the mean of the sampling distribution of the mean will be the same as the population mean.

The length of the missing side (the hypotenuse) is 10 ft.

We have,

We can use the Pythagorean theorem to find the length of the missing side of the right triangle.

So,

a² + b² = c²

where a and b are the lengths of the legs, and c is the length of the hypotenuse.

In this case,

The opposite side (which is the leg) has a length of 8 ft, and the adjacent side (which is the other leg) has a length of 6 ft.

Let x be the length of the missing side. Then we have:

a = 8 ft

b = 6 ft

c = x

Plugging these values into the Pythagorean theorem, we get:

8² + 6² = x²

64 + 36 = x²

100 = x²

Taking the square root of both sides, we get:

x = √100 = 10 ft

Therefore,

The length of the missing side (the hypotenuse) is 10 ft.

For vector arithmetic, vector addition (adding two vectors) and scalar multiplication (multiplying a vector by a scalar) is "component-wise". So when adding two vectors you add each component in the first vector to the corresponding one in the second to get the resulting vector. In scalar multiplication you multiply each vector component by the scalar and that gives the resulting vector.

So if u = <3,-2> and v = <-1,4>,

3u = <3*3,-2*3> = <9,-6>

2v = <-1*2,4*2> = <-2,8>

3u + 2v = <9,-6> + <-2,8> = <9+(-2),-6+8> = <7,2>

The area covered by the lawn sprinkler is approximately 461.63 square feet.

A circle is simply a closed 2-dimensional curved shape with no corners or edges.

The area of a circle is expressed mathematically as;

A = πr²

Where r is radius and π is constant pi ( π = 3.14 )

Given that; the diameter of the circle is 24.25 feet.

The radius of the circle is half of the diameter, so:

Radius r = diameter/2

Radius r = 24.25 / 2

Radius r = 12.125 feet

Next, plug the values into the above formula and solve for area.

Area = πr²

Area = 3.14 × ( 12.125 ft )²

Area = 3.14 × ( 12.125 ft )²

Area = 461.63 ft²

We cannot find the value of y'' at the point where x = 0 using this method.

To find y'' at the point where x = 0, we need to differentiate the given equation twice with respect to x.

First, we take the derivative of both sides with respect to x:

y + xy' + 4ey' = 0

Next, we take the derivative of this equation with respect to x:

y' + xy'' + y' + 4ey'' = 0

Simplifying this expression, we get:

2y' + xy'' + 4ey'' = 0

We are given that xy + 4ey = 4e. Differentiating this equation with respect to x, we get:

y + xy' + 4ey' = 0

Substituting y' = -(y + 4ey')/x from this equation into the previous equation, we get:

2y' - (y + 4ey') + 4ey'' = 0

Simplifying this expression, we get:

y'' = (y + 4ey' - 2y')/(4e)

When x = 0, we have y = 4e/4e = 1 and y' = -(1 + 4e*y')/0, which is undefined.

The correct sequence of transformations that could have been used to transform Trapezoid ABCD to produce trapezoid A''B''C''D'' is that trapezoid ABCD was reflected across the y-axis and then across the x-axis.

To transform trapezoid ABCD into trapezoid A''B''C''D'', we need to apply a sequence of transformations that will result in the same size and shape of the two trapezoids, which means that they are congruent.

One possible sequence of transformations that could have been used to transform trapezoid ABCD to produce trapezoid A''B''C''D'' is:

Trapezoid ABCD was reflected across the y-axis and then across the x-axis.

This sequence of transformations would result in the same size and shape of the two trapezoids, which means that they are congruent. Let's see why this is true.

When we reflect trapezoid ABCD across the y-axis, each point on the trapezoid is reflected across the y-axis, which means that its x-coordinate is multiplied by -1 while its y-coordinate remains the same. This results in a mirror image of the trapezoid on the opposite side of the y-axis.

Next, when we reflect the trapezoid across the x-axis, each point is reflected across the x-axis, which means that its y-coordinate is multiplied by -1 while its x-coordinate remains the same. This results in a mirror image of the trapezoid on the opposite side of the x-axis.

The resulting trapezoid is now in the same position and orientation as trapezoid A''B''C''D'', but it may not be in the same location. However, since the trapezoid is congruent, we can translate it to match the position of trapezoid A''B''C''D''.

Therefore, the correct sequence of transformations that could have been used to transform trapezoid ABCD to produce trapezoid A''B''C''D'' is that trapezoid ABCD was reflected across the y-axis and then across the x-axis.

Let's say the total work to be done is represented by 1.

On the first day, three-fifths of the work is completed. Therefore, the remaining work to be done is 1 - 3/5 = 2/5.

On the second day, three-quarters of the remainder is completed. The remainder after the first day's work is 2/5. So, the work completed on the second day is 3/4 x 2/5 = 3/10. The remaining work to be done is 2/5 - 3/10 = 1/5.

On the third day, seven-eighths of what remained is done. The remaining work to be done after the second day's work is 1/5. So, the work completed on the third day is 7/8 x 1/5 = 7/40.

Therefore, the fraction of work still remaining to be done is 1/5 - 7/40 = 8/40 - 7/40 = 1/40.

Answer:

y - 4 = 1/3(x + 5)

Step-by-step explanation:

The general equation for the point-slope form of a line is given by:

y - y1 = m(x - x1), where

Step 1:  To find the equation of the line through (-5, 4) and (1, 6), we first need to find the slope of the line using the slope formula, which is:

m = (y2 - y1) / (x2 - x1), where

We can allow (-5, 4) to be our (x1, y1) point and (1, 6) to be our (x2, y2) point:

m = (6 - 4) / (1 - (-5))

m = 2 / (1 + 5)

m = 2/6

m = 1/3

Now we can use the point-slope form of the equation with either of the two points.  

y - 4 = 1/3(x - (-5))

y - 4 = 1/3(x + 5)

Thus, the point-slope equation of the line through (-5, 4) and (1, 6) is:

y - 4 = 1/3(x + 5)

The probability that the kicker makes his first two kicks is 63.21%. This means that out of 100 attempts, the kicker is likely to make both kicks 63 times.

To solve this problem, we need to use conditional probability. We know that the kicker usually makes 71% of his first field goal attempts. So, the probability that he makes his first kick is 0.71. If he makes his first attempt, his success rate rises to 89%. So, the probability that he makes his second kick given that he made his first kick is 0.89.
Now, to find the probability that he makes his first two kicks, we need to multiply the probability of him making his first kick by the probability of him making his second kick given that he made his first kick. This can be represented as:
P(2 successful kicks) = P(1st kick is successful) x P(2nd kick is successful | 1st kick is successful)
P(2 successful kicks) = 0.71 x 0.89
P(2 successful kicks) = 0.6321 or 63.21%

The rate of change of a periodic function is itself a periodic function. In the case of a sinusoidal wave, the derivative is also a sinusoidal wave with the same period, but shifted by a phase angle of [tex]π/2.[/tex]

The rate of change of a periodic function at a specific point is equal to the instantaneous slope of the tangent line to the graph of the function at that point.

To calculate the rate of change of a periodic function, you need to take the derivative of the function with respect to the independent variable (usually time). If the function is a sinusoidal wave, you can use trigonometric identities to find the derivative.

For example, let's say we have a function f(t) = sin(t), which represents a sinusoidal wave. To find the rate of change of the function at a particular point t = a, we need to take the derivative of the function with respect to t:

f'(t) = cos(t)

Then we can evaluate this derivative at t = a to find the rate of change at that point:

f'(a) = cos(a)

This tells us the instantaneous rate of change of the function at the point t = a.

Note that the rate of change of a periodic function is itself a periodic function. In the case of a sinusoidal wave, the derivative is also a sinusoidal wave with the same period, but shifted by a phase angle of [tex]π/2.[/tex]

The rental company charges $55 for the first hour and then $10 per hour after that, we can use an explicit formula to calculate how much it will cost Jiya to rent the truck for 7 hours.

The explicit formula for the total cost of renting the truck for a given number of hours can be written as:

a(n) = c + (n-1)d

where a(n) is the total cost of renting the truck for n hours, c is the cost of the first hour, and d is the additional cost per hour.

Using this formula, we can find the cost of renting the truck for 7 hours:

a(7) = 55 + (7-1)*10

Simplifying the expression in the parentheses, we get:

a(7) = 55 + 6*10

Multiplying 6 by 10, we get:

a(7) = 55 + 60

Adding 55 and 60, we get:

a(7) = 115

Therefore, the explicit formula that describes how much it will cost Jiya to rent the truck for 7 hours is:

a7=55+(7-1)10

The trigonometric identity 1 + cot⁴θ = cosec⁴θ - 2cot²θ

Trigonometric identities are mathematical equations that contain trigonometric ratios in which one side is equal to the other.

Given the trigonometric identity

1 + cot⁴θ = cosec⁴θ - 2cot²θ, we need to show that the Left hand side L.H.S equals the Right Hand side R.H.S. we proceed as follows.

So, L.H.S = 1 + cot⁴θ

Now using the trigonometric identity

1 + cot²θ = cosec²θ

Making cot²θ subject of the formula, we have that

cot²θ = cosec²θ - 1

So, substituting this into the equation, we have that

1 + cot⁴θ =  1 + (cot²θ)²

= 1 + (cosec²θ - 1)²

Expanding the bracket, we have that

= 1 + cosec⁴θ - 2cosec²θ + 1

=  cosec⁴θ - 2cosec²θ + 1 + 1

=  cosec⁴θ - 2cosec²θ + 2

=  cosec⁴θ + 2 - 2cosec²θ

= cosec⁴θ + 2(1 - cosec²θ)

= cosec⁴θ + 2cot²θ

= R.H.S

Answer:

y = 4x^2 + 32x + 28

Step-by-step explanation:

Before we can find the standard form of the quadratic function with the given coordinates, we must first start with the intercept form, whose general equation is

y = a(x - p)(x - q), where

Step 1:  We can plug in (-6, -20) for x and y, -7 for p and -1 for q into the intercept form.  This will allows us to solve for a:

-20 = a(-6 - (-7))(-6 - (-1))

-20 = a(-6 + 7)(-6 + 1)

-20 = a(1)(-5)

-20 = -5a

4 = a

Thus, the full equation in vertex form is

y = 4(x + 7)(x + 1).

Step 1:  The general equation for standard form is

y = ax^2 + bx + c.

We can convert from vertex to standard form by simply expanding the expression.  Let's ignore the 4 for a moment simply focus on (x + 7)(x + 1).

We can expand using the FOIL method, where you multiply

We see that the first terms are x and x, the outer terms are x and 1, the inner terms are 7 and x and the last terms are 7 * 1.  Now, we multiply and simplify:

(x * x) + (x * 1) + (7 * x) + (7 * 1)

x^2 + x + 7x + 7

x^2 + 8x + 7

Step 3:  Now, we can distribute the four to each term with multiplication:

4(x^2 + 8x + 7)

4x^2 + 32x + 28

Optional Step 4:  We can check that our quadratic function in standard form, by plugging in -7, -1, and -6 for x and seeing that we get 0 as the y value for both x = -7 and x = -1 and -20 as the y value for x = -6:

Checking that (-7, 0) lies on the parabola of 4x^2 + 32x + 28:

0 = 4(-7)^2 + 32(-7) + 28

0 = 4(49) - 224 + 28

0 = 196 - 196

0 = 0

Checking that (-1, 0) lies on the parabola of 4x^2 + 32x + 28:

0 = 4(-1)^2 + 32(-1) + 28

0 = 4(1) - 32 + 28

0 = 4 - 4

0 = 0

Checking that (-6, -20) lies on the parabola of 4x^2 + 32x + 28:

-20 = 4(-6)^2 + 32(-6) + 28

-20 = 4(36) -192 + 28

-20 = 144 -164

-20 = -20

I attached a graph from Desmos to show how the function y = 4x^2 + 32x + 28 contains the points (-7, 0), (-1, 0), (-6, 20), further proving that we've correctly found the quadratic function in standard form passing through these three points
