For a scaler variable, the Gaussian distribution has a probability density function of

p(x |µ, σ² ) = N(x; µ, σ² ) = 1 / 2π×[tex]e^{\frac{-(x-u)^{2}}{2s^{2} } }[/tex]

The term will have a maximum value at the top of the slope of the 1-D Gaussian distribution curve that is when exp(0) =1 or when x = µ

Step-by-step explanation:

Gaussian distributions have similar shape, with the mean controlling the location and the variance controls the dispersion  

From the graph of the probability distribution function it is seen that the the peak is the point at which the slope = 0, where µ = 0 and σ² = 1 then solution for the peak = exponential function = 0 or x = µ

Answer:

5.42 hours

Step-by-step explanation:

Let x represent time taken to complete 300 miles.

We have been given that Bryce a previous winner of the contest, made a trip of 360 miles in a 6.5 hours.

We will use proportions to solve our given problem since rates are same for both distances.

[tex]\frac{\text{Distance covered}}{\text{Time taken}}=\frac{360\text{ Miles}}{6.5\text{ Hours}}[/tex]

Upon substituting our given values in above proportion, we will get:

[tex]\frac{300\text{ Miles}}{x}=\frac{360\text{ Miles}}{6.5\text{ Hours}}[/tex]

Cross multiply:

[tex]x\cdot 360\text{ Miles}=300\text{ Miles}\times6.5\text{ Hours}}[/tex]

[tex]x=\frac{300\text{ Miles}\times6.5\text{ Hours}}{ 360\text{ Miles}}[/tex]

[tex]x=\frac{300\times6.5\text{ Hours}}{360}[/tex]

[tex]x=5.41666\text{ Hours}\approx 5.42\text{ Hours}[/tex]

The volume of the square prism with a side of base decreasing at a rate of 7 km/min and height increasing at 10 km/min is decreasing at a rate of 344 cubic km/min.

In this problem, we're dealing with rates of change and the geometric properties of a square prism. A square prism can be characterized by the side length of its base (we'll call this length 's') and its height (h). The volume (V) of a square prism is given by the equation V = s^2 * h. We're told that the side length s is decreasing at a rate of 7 kilometers per minute (ds/dt = -7 km/min) and the height h is increasing at a rate of 10 kilometers per minute (dh/dt = 10 km/min).

To find the rate at which the volume is changing with respect to time, we can take the derivative of the volume equation with respect to time. Thus, dV/dt = 2*s*ds/dt*h + s^2*dh/dt. Substituting the given values, when s = 4 km and h = 9 km, we find: dV/dt = 2*4*(-7)*9 + 4^2*10 = -504 + 160 = -344 cubic kilometers per minute. Therefore, at the given instant, the volume of the square prism is decreasing at a rate of 344 cubic kilometers per minute.

The rate of change of the surface area of the prism at that instant is -204 square kilometers per minute. Correct Option is Option C.

To solve this problem, let's first start by identifying the formula for the surface area (SA) of a square prism, which is given as [tex]2s^2 + 4sh[/tex] , where s is the side of the base and h is the height.

Now, let's find the rate of change of the surface area with respect to time, dSA/dt. We'll use the chain rule to differentiate the surface area formula:

1. Differentiate the given surface area formula:

[tex]SA = 2s^2 + 4sh[/tex]

[tex]d(SA)/dt = d(2s^2)/dt + d(4sh)/dt[/tex]

2. Apply the chain rule:

d(SA)/dt = 2 * 2s * (ds/dt) + 4 * (s * (dh/dt) + h * (ds/dt))

3. Plug in the given values: s = 4 km, ds/dt = -7 km/min, h = 9 km, dh/dt = 10 km/min:

d(SA)/dt = 4 * 4 * (-7) + 4 * (4 * 10 + 9 * (-7))

d(SA)/dt = -112 + 4 * (40 - 63)

d(SA)/dt = -112 + 4 * (-23)

d(SA)/dt = -112 - 92

d(SA)/dt = -204

Answer:

Step-by-step explanation:

The current global population is growing at an annual rate of 1.35 percent. The growth rate is exponential. We would apply the formula for exponential growth which is expressed as

A = P(1 + r)^t

Where

A represents the population after t years.

t represents the number of years.

P represents the initial population.

r represents rate of growth.

From the information given,

P = 6.1 × 10^9

r = 1.35% = 1.35/100 = 0.0135

t = 1

Therefore

A = 6.1 × 10^9(1 + 0.0135)^1

A = 6.1 × 10^9(1.0135)^1

A = 6182350000

The number of people that would be added is

6182350000 - 6100000000

= 82350000

If the world population were to keep growing at 1.35%, we number of people who would be added next year is 82,350,000 people.

The population of the world is growing at 1.35%. This means that next year, the number of people added will be 1.35% of the current population.

The current population is 6.1 billion so the number of people who will be added is:

= Population x Incremental rate

= 6,100,000,000 x 1.35%

= 82,350,000 people

In conclusion, 82,350,000 people will be added.

Answer:

dA/dt = 16 square inches per second

Step-by-step explanation:

Width of rectangle is w

Height of rectangle is h

width = twice height

w = 2h

Area = wh = (2h)*h

A = 2h^2

Differentiating the equation with respect to time

dA/dt = 2+2h dh/dt

dA/dt = 4h dh/dt

According to the given situation when width is 4 inches

h = w/2

h = 2

Rate of change of A is  

dA/dt = wh dh/dt

dA/dt = 4(2)(2)

dA/dt = 16 square inches per second

The rate of change of the area of the rectangle with respect to time at the specified instant is 16 square inches per second.

The question asks for the rate of change of the area of a rectangle with respect to time, where the rectangle's width is twice its height, both width and height are functions of time and the rate at which height is increasing is given.

The area A of the rectangle is given by the formula A = w*h. Substituting w = 2h into the formula gives A = 2h². The rate of change of the area with respect to time (dA/dt) can be found by differentiating A with respect to time. By the chain rule this gives dA/dt = 2*2h(dh/dt) = 4h*dh/dt.

At the given instant, where the width is 4 inches (so the height is 2 inches) and the rate of change of the height is 2 inches per second, we have dA/dt = 4*2*2 = 16 square inches per second. Therefore, the rate of change of the area of the rectangle with respect to time at that instant is 16 square inches per second.

Answer:

The height of the wall is 52.2 feet.

Step-by-step explanation:

Given:

From the figure shown, HT is the height of Carlos, 'V' is the position of mirror.

So, TV = 4 ft, VS = 36 ft, HT = 5.8 ft.

Let the height of the wall be 'x'. So, JS = 'x'

Now, consider the two triangles HTV and JVS

Statements                                                               Reasons

1. ∠ HTV ≅ ∠ JSV                                           Right angles are congruent

2. ∠ HVT ≅ ∠ JVS                                          Given in the figure

Therefore, ΔHTV and Δ JVS are similar triangles by AA postulate.

Now, from definition of similar triangles, corresponding sides of two similar triangles are in proportion to each other. Therefore,

[tex]\frac{HT}{JS}=\frac{TV}{VS}=\frac{HV}{JV}[/tex]

Considering the first two pair of fractions, we have:

[tex]\frac{5.8}{x}=\frac{4}{36}\\\\36\times 5.8=4\times x\\\\x=\frac{36\times 5.8}{4}\\\\x=9\times 5.8=52.2\ ft[/tex]

Answer:

19

Step-by-step explanation:

If the scientist chooses 60 random eggs then the overall probability of selecting yellow eggs is 32%. So, there's a chance of he randomly collecting 60 eggs out of which 19 could be yellow.

(60/100) x 32 ~ 19...

The usual number of yellow dragon eggs expected in a sample of 60, given a 32% probability, is 19 when rounded to the nearest whole number.

The question at hand involves finding the expected number of yellow eggs in a sample size of 60, given a known probability of a yellow egg occurrence.

Since we know that 32% of the dragon eggs on planet Pern are yellow, we can calculate the usual number of yellow eggs in the samples by multiplying the sample size (60 eggs) by the probability of getting a yellow egg (0.32).

Therefore, the expected or usual number of yellow eggs in the sample would be 60 × 0.32 = 19.2.

Considering that we cannot have a fraction of an egg, the usual number of yellow eggs in samples of 60 eggs would typically be rounded to the nearest whole number, which is 19.

To calculate the number of floors a building can have for a given height, use the formula 'Number of Floors = h / 12', where 'h' is the total building height in feet and each floor is 12 feet tall.

Explanation:

To write an expression for the number of floors a building can have for a given building height, where each floor is 12 feet tall, we use the following formula:

Number of Floors = Total Building Height (in feet) / Height of One Floor (in feet)

Let 'h' represent the total height of the building in feet. Then the expression becomes:

Number of Floors = h / 12

For example, if a building has a height of 384 feet, the number of floors can be calculated as 384 feet / 12 feet per floor = 32 floors.

To calculate the cost, multiply the amount of turkey per student (0.3 pounds) by the number of students (100), then multiply the total pounds needed (30) by the cost per pound ($0.79), resulting in a total cost of $23.70 for turkey for 100 students.

Explanation:

The question asks us to calculate the cost of providing turkey to 100 students if each student requires 0.3 pounds of turkey, and turkey costs $0.79 per pound. To find the total amount of turkey needed, we multiply the amount each student gets by the total number of students: 0.3 pounds/student × 100 students. This calculation results in 30 pounds of turkey required for 100 students.

Next, to determine the total cost, we multiply the total pounds of turkey needed by the cost per pound: 30 pounds × $0.79/pound. This calculation gives us a total cost of $23.70 for the turkey.

Therefore, it will cost $23.70 to give turkey to 100 students.

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 100

p = 15% = 0.15

Number of bags overfilled , x = 21

First, we design the null and the alternate hypothesis  

[tex]H_{0}: p = 0.15\\H_A: p > 0.15[/tex]

Formula:

[tex]\hat{p} = \dfrac{x}{n} = \dfrac{21}{100} = 0.21[/tex]

[tex]z = \dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}[/tex]

Putting values, we get,

[tex]z = \dfrac{0.21-0.15}{\sqrt{\dfrac{0.15(1-0.15)}{100}}}\\\\z = 1.68[/tex]

Thus, the correct answer is

Option A) 1.68

To test the hypothesis H0: p = 0.15 versus Ha: p > 0.15, the test statistic is Z = 1.68.

To test the hypothesis H0: p = 0.15 versus Ha: p > 0.15, where p is the true proportion of overfilled bags, we can use the test statistic Z. The formula for the test statistic is Z = (P' - p) / √(p(1-p) / n), where P' is the sample proportion, p is the hypothesized proportion, and n is the sample size.

In this case, the sample proportion P' = 21/100 = 0.21, the hypothesized proportion p = 0.15, and the sample size n = 100.

Plugging these values into the formula, we get Z = (0.21 - 0.15) / √(0.15(1-0.15) / 100) = 1.68.

Therefore, the test statistic is Z = 1.68.

Step-by-step explanation:

The formula for the tangent of the difference of angles is ...

  tan(a-b) = (tan(a) -tan(b))/(1 +tan(a)tan(b))

Filling in the values a=23° and b=21°, you get the formula shown above.

The expression for tan(23°−21°) in terms of the tangents of 23° and 21° is: tan(23°−21°) = (tan 23° - tan 21°) / (1 + tan 23° * tan 21°).

To express tan(23°−21°) in terms of the tangents of 23° and 21°, we can use the angle subtraction formula for tangent, which is:

tan(α - β) = (tan α - tan β) / (1 + tan α * tan β)

Applying this to tan(23°−21°), we get:

tan(23°−21°) = (tan 23° - tan 21°) / (1 + tan 23° * tan 21°)

We can't directly calculate the values from the given table since 23° and 21° are not listed. However, we understand the formula required to express tan(23°−21°) in terms of the tangents of these two angles.

  25u -4.50 = 55.50

  25u = 60

  u = 60/25 = 2.40

The cost of the 100 lb container is 100u = 240. The cost of the 75 lb container is $55.50 less: 240 -55.50 = 184.50.

The 100 lb container costs $240. The 75 lb container costs $184.50.

Final answer:

The chicken quesadilla contains a total of 542 kilocalories, which is derived by summing the caloric contributions from protein, carbohydrate, and fat.

Explanation:

To calculate the number of kilocalories in a chicken quesadilla with 28 grams of protein, 40 grams of carbohydrate, and 30 grams of fat, we use the known caloric values for each macronutrient. Protein and carbohydrate each have 4 Calories per gram, while fat has 9 Calories per gram.

Protein: 28 grams × 4 Calories/gram = 112 Calories

Carbohydrate: 40 grams × 4 Calories/gram = 160 Calories

Fat: 30 grams × 9 Calories/gram = 270 Calories

Adding up these amounts, we have:

112 Calories (from protein) + 160 Calories (from carbohydrate) + 270 Calories (from fat) = 542 Calories

To convert Calories into kilocalories, we remember that 1 kilocalorie = 1 Calorie. Therefore, the chicken quesadilla contains 542 kilocalories.

Answer: the distance from the base of the ladder from the building is 10 feet.

Step-by-step explanation:

The ladder forms a right angle triangle with the wall of the building and the ground.

The length of the ladder represents the hypotenuse of the right angle triangle.

The distance, h of the base of the ladder from the building represents the adjacent side of the triangle.

To determine h, we would apply

the cosine trigonometric ratio.

Cos θ = adjacent side/hypotenuse. Therefore,

Cos 60 = h/20

h = 20Cos60 = 20 × 0.5

h = 10 feet

Final answer:

To solve for the distance from the base of the ladder to the building, the cosine function is used because the scenario forms a right-angled triangle with the ground and the wall. By the equation cos(60°) = Base / Hypotenuse, with the ladder being the hypotenuse, the base is calculated to be 10 feet from the building.

Explanation:

The question involves using trigonometry to determine the distance from the base of the ladder to the building. When a ladder makes a 60° angle with the ground and its length is given (20 feet), this forms a right-angled triangle with the ground and the building's wall. To find the distance from the base of the ladder to the building, we can use the cosine function, which relates the adjacent side to the hypotenuse in a right-angled triangle.

Using the equation:

cos(60°) = Base / Hypotenuse

Here, the hypotenuse is the length of the ladder which is 20 feet. Therefore:

cos(60°) = Base / 20 feet

cos(60°) equals 0.5 when calculating in degrees. Consequently:

0.5 = Base / 20 feet

Multiplying both sides by 20 gives:

Base = 20 feet * 0.5

Base = 10 feet

Thus, the base of the ladder is 10 feet from the building.

Answer:

27° (as an integer)

Step-by-step explanation:

From the figure given;

DC = 8 units

BC = 4 units

We are required to determine m∠D

We need to use the appropriate trigonometric ratio;

In this case, DC is adjacent and BC is opposite to m∠D

Therefore, the appropriate trigonometric ratio is tangent;

That is;

Tan m∠D = BC ÷ DC

               = 4 ÷ 8

               = 0.5

Thus;

m∠D = Tan^-1 (0.5)

        = 26.57

         = 27 (as an integer)
