The probability that a aimlessly  named person's triglyceride  position is  lower than 80 milligrams per deciliter is  roughly0.0618 or6.18.    

To calculate the probability that a aimlessly  named person's triglyceride  position is  lower than 80 milligrams per deciliter, we can use the conception of standard normal distribution.  

First, we need to  regularize the value of 80 using the z- score formula  z = ( x- μ)/ σ  Where  x =  80( the value we want to calculate the probability for)  μ =  134( mean triglyceride  position)  σ =  35( standard  divagation)  Plugging in the values, we get  z = ( 80- 134)/ 35  z = -54/ 35  z ≈-1.543

Next, we need to find the corresponding area under the standard normal distribution  wind for a z- score of-1.543. We can use a standard normal distribution table or a calculator to find this area.

Looking up the z- score in the table or using a calculator, we find that the area to the left wing of z = -1.543 is  roughly0.0618.  

thus, the probability that a aimlessly  named person's triglyceride  position is  lower than 80 milligrams per deciliter is  roughly0.0618 or6.18.

Answer:

  150 m²

Step-by-step explanation:

You want the total area of a figure consisting of a 12 m wide rectangle 5 m high with a triangle above that bringing the total height to 20 m.

The area of the rectangle is the product of its length and width:

  A = LW

  A = (12 m)(5 m) = 60 m²

The area of the triangle is half the product of its base and height.

  A = 1/2bh

  A = 12/(12 m)(20 -5 m) = 90 m²

The area of the whole figure is the sum of the areas of its parts:

  total area = rectangle area + triangle area

  total area = 60 m² +90 m² = 150 m²

The area of the figure is 150 m².

__

Additional comment

Since you know a triangle's area is equivalent to the area of a rectangle that has half the height, the 15 m high triangle can be considered as a rectangle 7.5 m high. Adding that to the 5 m area of the rectangle already there gives the equivalent area as that of a rectangle 12 m wide and 5+7.5 = 12.5 m high: (12 m)(12.5 m) = 150 m².

The probability that a given student said math was their favorite subject was 3.44

The mathematical notion of probability measures the possibility of an event happening. A number between 0 and 1 is used to indicate it, with 0 denoting impossibility (the event won't happen) and 1 denoting certainty (the event will unquestionably happen). In probability theory, the probability of an event is determined based on a set of assumptions or information available. It is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

Here, the total outcome is 299 and favorable outcome is 87.

Hence, the probability is 299/87 = 3.44

Therefore, probability that a given student said math was their favorite subject was 3.44.

The critical value of the chi-squared statistic with a significance level of 0.05 is 3.84. Therefore, the correct answer is option B.

The null hypothesis in this case would be that there is independence between the type of sleeping pill and the presence of any adverse health condition.

The critical value needed to test for this is the chi-squared statistic with a significance level of 0.05.

To calculate the critical value, we first need to calculate the degrees of freedom,  which is calculated by (rows-1) * (columns-1).  In this case, the degrees of freedom is (2-1)*(2-1) = 1.

The critical value of the chi-squared statistic with a significance level of 0.05 is 3.84. This means that if the calculated chi-squared statistic is greater than 3.84, then we can reject the null hypothesis and claim that there is a significant relationship between the type of sleeping pill and the presence of any adverse health condition.

Therefore, the critical value of the chi-squared statistic with a significance level of 0.05 is 3.84. Therefore, the correct answer is option B.

The equation of the parabola with the given focus (2, 7) and directrix y = -1 is [tex](x - 2)^2 = 12(y - 3)^2[/tex].Option C.

To find the equation of the parabola with a focus and directrix, we can use the standard form of the equation of a parabola:

For a vertical parabola:

[tex](x - h)^2 = 4p(y - k),[/tex]

where (h, k) is the vertex, and p is the distance from the vertex to the focus and directrix.

In this case, the focus is given as (2, 7), which means the vertex is also (2, 7) since the focus and vertex lie on the axis of symmetry. Additionally, the directrix is given as y = -1, which means the directrix is a horizontal line.

First, let's determine the distance from the vertex to the focus and directrix, which is the value of p. The distance is the absolute difference between the y-coordinate of the focus (7) and the y-coordinate of the directrix (-1):

p = |7 - (-1)| = 8.

Now we can substitute the values of the vertex (h, k) = (2, 7) and p = 8 into the standard form equation:

[tex](x - 2)^2 = 4(8)(y - 7).[/tex]

Simplifying further:

[tex](x - 2)^2 = 32(y - 7).[/tex]

Expanding the equation:

[tex]x^2 - 4x + 4 = 32y - 224.[/tex]

Rearranging the terms:

[tex]x^2 - 4x - 32y + 228 = 0.[/tex]

Therefore, the equation of the parabola with the given focus (2, 7) and directrix y = -1 is  [tex](x - 2)^2 = 12(y - 3)^2.[/tex] SO Option C is correct.

Final speed after slowing down by 15 miles per hour and reducing the speed by one third is 25 miles per hour.

Let's break down the steps to determine the final speed:

Step 1: Convert the speed from miles per minute to miles per hour.

Since you're driving one and a half miles per minute, we need to convert it to miles per hour. There are 60 minutes in an hour, so we multiply 1.5 by 60 to get 90 miles per hour.

Step 2: Slow down by 15 miles per hour.

Subtract 15 from the initial speed of 90 miles per hour, resulting in 75 miles per hour.

Step 3: Reduce the speed by one third.

To find one third of 75 miles per hour, we divide it by 3, which gives us 25 miles per hour.

Therefore, the final speed after slowing down by 15 miles per hour and reducing the speed by one third is 25 miles per hour.

Step-by-step explanation:

:]

Let's use x to represent the cost of one refrigerator and y to represent the cost of one fan.

The equations become:

Equation 1: x + 2y = 1219

Equation 2: 2x + 3y = 2155

Using the same substitution method:

From Equation 1, we have:

x = 1219 - 2y

Substitute this expression for x in Equation 2:

2(1219 - 2y) + 3y = 2155

Simplify the equation:

2438 - 4y + 3y = 2155

-y = 2155 - 2438

-y = -283

===> y = 283

Now substitute the value of y back into Equation 1 to find x:

===> x + 2(283) = 1219

===> x + 566 = 1219

===> x = 1219 - 566

===> x = 653

Therefore, the cost of one refrigerator is $653.

Based on the given assumptions and calculations, the net present value (NPV) of the investment in the new piece of equipment is -$27,045.76, indicating that the investment is not favorable.

To calculate the after-tax cash flows for each year and evaluate the investment decision, let's use the following information:

Assumptions:

Tax depreciation is straight-line over five years.

Pre-tax salvage value is $10,000 in Year 5 and $15,000 if the asset is scrapped in Year 4.

Tax on salvage value is 30% of the difference between salvage value and book value of the investment.

The cost of capital is 12%.

Given:

Initial investment cost = $50,000

Useful life of the equipment = 5 years

To calculate the depreciation expense each year, we divide the initial investment by the useful life:

Depreciation expense per year = Initial investment / Useful life

Depreciation expense per year = $50,000 / 5 = $10,000

Now, let's calculate the book value at the end of each year:

Year 1:

Book value = Initial investment - Depreciation expense per year

Book value [tex]= $50,000 - $10,000 = $40,000[/tex]

Year 2:

Book value = Initial investment - (2 [tex]\times[/tex] Depreciation expense per year)

Book value [tex]= $50,000 - (2 \times$10,000) = $30,000[/tex]

Year 3:

Book value = Initial investment - (3 [tex]\times[/tex] Depreciation expense per year)

Book value = $50,000 - (3 [tex]\times[/tex] $10,000) = $20,000

Year 4:

Book value = Initial investment - (4 [tex]\times[/tex] Depreciation expense per year)

Book value [tex]= $50,000 - (4 \times $10,000) = $10,000[/tex]

Year 5:

Book value = Initial investment - (5 [tex]\times[/tex] Depreciation expense per year)

Book value [tex]= $50,000 - (5 \times $10,000) = $0[/tex]

Based on the assumptions, the salvage value is $10,000 in Year 5.

If the asset is scrapped in Year 4, the salvage value is $15,000.

To calculate the tax on salvage value, we need to find the difference between the salvage value and the book value and then multiply it by the tax rate:

Tax on salvage value = Tax rate [tex]\times[/tex] (Salvage value - Book value)

For Year 5:

Tax on salvage value[tex]= 0.30 \times ($10,000 - $0) = $3,000[/tex]

For Year 4 (if scrapped):

Tax on salvage value[tex]= 0.30 \times ($15,000 - $10,000) = $1,500[/tex]

Now, let's calculate the after-tax cash flows for each year:

Year 1:

After-tax cash flow = Depreciation expense per year - Tax on salvage value

After-tax cash flow = $10,000 - $0 = $10,000

Year 2:

After-tax cash flow = Salvage value - Tax on salvage value

After-tax cash flow = $0 - $0 = $0

Year 3:

After-tax cash flow = Salvage value - Tax on salvage value

After-tax cash flow = $0 - $0 = $0

Year 4 (if scrapped):

After-tax cash flow = Salvage value - Tax on salvage value

After-tax cash flow = $15,000 - $1,500 = $13,500

Year 5:

After-tax cash flow = Salvage value - Tax on salvage value

After-tax cash flow = $10,000 - $3,000 = $7,000

Now, let's calculate the net present value (NPV) using the cost of capital of 12%.

We will discount each year's after-tax cash flow to its present value using the formula:

[tex]PV = CF / (1 + r)^t[/tex]

Where:

PV = Present value

CF = Cash flow

r = Discount rate (cost of capital)

t = Time period (year)

NPV = PV Year 1 + PV Year 2 + PV Year 3 + PV Year 4 + PV Year 5 - Initial investment

Let's calculate the NPV:

PV Year 1 [tex]= $10,000 / (1 + 0.12)^1 = $8,928.57[/tex]

PV Year 2 [tex]= $0 / (1 + 0.12)^2 = $0[/tex]

PV Year 3 [tex]= $0 / (1 + 0.12)^3 = $0[/tex]

PV Year 4 [tex]= $13,500 / (1 + 0.12)^4 = $9,551.28[/tex]

PV Year 5 [tex]= $7,000 / (1 + 0.12)^5 = $4,474.39[/tex]

NPV = $8,928.57 + $0 + $0 + $9,551.28 + $4,474.39 - $50,000

NPV = $22,954.24 - $50,000

NPV = -$27,045.76

The NPV is negative, which means that based on the given assumptions and cost of capital, the investment in the new piece of equipment would result in a net loss.

Therefore, the investment may not be favorable.

Please note that the calculations above are based on the given assumptions, and additional factors or considerations specific to the business should also be taken into account when making investment decisions.
