Answer:

a) The point estimate is 6995.

b) The margin of error is of 1691.

c) The standard error is of 1000

Step-by-step explanation:

a. Determine the point estimate for the prediction of student expenditures at a university with a graduation rate of 40%.

The point estimate is the mean of the two bounds of the confidence interval. So

[tex]P = \frac{5304 + 8686}{2} = 6955[/tex]

The point estimate is 6995.

b. Calculate the margin of error.

The margin of error is the difference between the bounds and the point estimate. So

M = 8686 - 6995 = 6995 - 5304 = 1691

The margin of error is of 1691.

c. Calculate the standard error of the prediction of student expenditures at a university with a graduation rate of 40%.

Now I have to expand a bit into the confidence interval.

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.9}{2} = 0.05[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.05 = 0.95[/tex], so Z = 1.645.

The margin of error is:

[tex]M = zs[/tex]

In which s is the margin of error.

We have that M = 1691. So

[tex]M = zs[/tex]

[tex]s = \frac{M}{z} = \frac{1645}{1.645} = 1000[/tex]

The standard error is of 1000

The length of segment A'B' from the triangle A'B'C' is 6 units.

Given that, triangle A'B'C' is the image of ABC under a dilation with a scale factor of 2.

In the given triangle ABC, AB=3 units

The basic formula to find the scale factor of a figure is expressed as,

Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.

2=Dimensions of the new shape/3

Dimensions of the new shape=6 units

Therefore, the length of segment A'B' from the triangle A'B'C' is 6 units.

Answer:

x = 3

Step-by-step explanation:

2 + 3x = 11

3x = 11 - 2

3x = 9 (divide both sides by 3 to get x)

3x/3 = 9/3

x = 3

In the given exponential equations: [tex]2^3x[/tex] = 11, the value of x is [tex]\frac{log_211}{3}[/tex].

Mathematically, an equation is a statement that asserts the equivalency of two expressions. It consists of two hands, the left-hand side( LHS) and the right-hand side( RHS), separated by an equal sign( =). The LHS and RHS can be numbers, variables, constants, or further complex fine expressions.

Equations can be classified based on their degree, which corresponds to the highest power of the variables involved. For example, linear equations have a degree of 1, quadratic equations have a degree of 2, and so on.

Given the equation:

[tex]2^3^x[/tex] = 11

Take the logarithm of both sides,

log [tex]2^3^x[/tex] = log 11

3x log2 = log 11

3x = [tex]\frac{log 11}{log2}[/tex]

3x = [tex]log_211[/tex]

x = [tex]\frac{log_211}{3}[/tex].

So, the value of x is [tex]\frac{log_211}{3}[/tex].

Answer:

  240 ft by 480 ft

Step-by-step explanation:

Area is maximized when the long side is half the total length of the fence. That makes the short side (out from the river) be half the length of the long side.

The fenced field dimensions are 240 feet by 480 feet.

__

You can let x represent the length of the long side. Then the length of the short side is half the remaining fence: (960 -x)/2.

The total area is the product of these dimensions:

  A = x(960 -x)/2

We note that this is the equation of a parabola with zeros at x=0 and x=960. The maximum will be found on the line of symmetry, halfway between the zeros. That is at x = (0 +960)/2 = 480.

The area is maximized for a long-side dimension of 480 feet. The short sides are 240 feet.

Edge

Answer:

Yes

Step-by-step explanation:

Remember in order for the rates to be proportional it has to have a constant rate of change and it has to go through the origin if graphed

For one this has a constant rate of change which is 3 dollars per 25 messages

Now we just have to find out if it would go through the origin (0,0)

To do so we subtract 3 dollars and then 25 messages

6-3=3

50 - 25 =25

then again 25-25=0

3-3=0

concluding that (0,0) is a solution

Thus meaning that this is a proportional relationship

Answer:

2√73 or 17.09 inches

Step-by-step explanation:

The small red square at the corner of the triangle symbolizes that the triangle is a right triangle. Therefore, to find the hypotenuse of the triangle, we can use the Pythagorean Theorem: a² + b² = c²

a = 6

b = 16

c = ?

Plug these values into the equation.

(6)² + (16)² = c²

Evaluate the exponents.

36 + 256 = c²

292 = c²

Take the square root of both sides to find c.

√292 = √c²

17.09 ≈ c

This is your answer.

You can also simplify the radical without using decimals.

4 • 73 = 292

Therefore,

√4 • √73 = √292

Which also means,

2•√73 = √292

So your answer is: 2√73

Hope this helps!

Answer:

We use the pythagorean theorem a²+b²=c² and in this question

a = 6

and

b = 16

so

36 + 256 = c²

so

c² = 292 so now we take the square root of it to get [tex]\sqrt{292}[/tex]

*This is the graph of a [NON-LINEAR].

*The y-intercept of the graph is the function value y=[0]. *The smallest positive x-intercept of the graph is located at x=[π/2]. *The greatest value of y is y=[2]. *For x between x= -π and x= -π/2, the function value y[>]0.

This is the graph of a sin function.

The y-intercept of the graph is the function value y = 0

The smallest positive x-intercept of the graph is located at x = π/2

The greatest value of y is y = 2

For a between x = -π and x = -π/2 the function value y > 0

A sine function graph represents the behavior of the sine function over a specific interval. The graph of a sine function has the following characteristics:

Shape: The graph of a sine function resembles a wave. It consists of a series of repeated crests (peaks) and troughs (valleys) that oscillate above and below a central line called the midline.

Period: The graph repeats itself over a specific interval called the period. The standard period of the sine function is 2π radians or 360 degrees. This means that the graph completes one full wave cycle in this interval.

Amplitude: The amplitude determines the vertical distance between the midline and the maximum or minimum points of the graph. It represents the maximum deviation of the function from the midline. The amplitude of the sine function is always positive.

Midline: The midline is the horizontal line that the sine function oscillates around. It is located between the maximum and minimum points of the graph and has a constant y-value.
