The standard deviation of returns is 0.0665 when a person is holding stock and there are three possible outcomes.

To calculate the expected return, we multiply the probability of each state by its corresponding return and sum them up:

Expected return = (20% * 18%) + (55% * 9%) + (25% * -5%)

Expected return = 0.20 * 0.18 + 0.55 * 0.09 + 0.25 * (-0.05)

Expected return = 0.036 + 0.0495 - 0.0125

Expected return = 0.073

The expected return is 7.30%.

To calculate the standard deviation of returns, we need to find the variance first. The variance is calculated as the weighted sum of squared deviations from the expected return:

Variance = (20% * (18% - 7.30%)^2) + (55% * (9% - 7.30%)^2) + (25% * (-5% - 7.30%)^2)

Variance = 0.20 * (0.1077)^2 + 0.55 * (0.0177)^2 + 0.25 * (-0.123)^2

Variance = 0.00232 + 0.000173 + 0.001903

Variance = 0.004423

The standard deviation is the square root of the variance:

Standard deviation = √(0.004423)

Standard deviation = 0.0665

Therefore, the value obtained is 0.0665.

The ordered pair that is on the function y=f(2x+1)+3 is (-3/2, 6)

Here we know that for the function:

y = f(x)

And we know that the point (-2, 3) belongs to the function, this means that:

f(-2)= 3

Now we want to find a point on the function:

f(2x + 1) + 3

If we find x such that:

2x + 1 = -2

2x = -3

x = -3/2

Now we can evaluate the function in that value of x to get:

y = f(2*-3/2 + 1) + 3

y = f(-2) + 3

y = 3 + 3

y = 6

Then we have the point (-3/2, 6) on the function.

1. (f ◦ f)(x) = x + 10.
2. (f ◦ g)(x) = x + 10.
3. (g ◦ f)(x) = x + 10.
4. (g ◦ g)(x) = x + 10.

1. (f ◦ f)(x):
To find (f ◦ f)(x), we need to perform the composition of the functions f(x) and f(x).

First, let's find f(f(x)). We substitute f(x) into the function f(x), which gives us f(f(x)) = f(x + 5).

Now, let's substitute x + 5 into the function f(x). We get f(f(x)) = f(x + 5) = (x + 5) + 5 = x + 10.

Therefore, (f ◦ f)(x) = x + 10.

2. (f ◦ g)(x):
To find (f ◦ g)(x), we need to perform the composition of the functions f(x) and g(x).

First, let's find f(g(x)). We substitute g(x) into the function f(x), which gives us f(g(x)) = f(1(x + 5)).

Now, let's substitute 1(x + 5) into the function f(x). We get f(g(x)) = f(1(x + 5)) = 1(x + 5) + 5 = x + 5 + 5 = x + 10.

Therefore, (f ◦ g)(x) = x + 10.

3. (g ◦ f)(x):
To find (g ◦ f)(x), we need to perform the composition of the functions g(x) and f(x).

First, let's find g(f(x)). We substitute f(x) into the function g(x), which gives us g(f(x)) = 1(f(x) + 5).

Now, let's substitute f(x) + 5 into the function g(x). We get g(f(x)) = 1(f(x) + 5) = 1((x + 5) + 5) = 1(x + 10) = x + 10.

Therefore, (g ◦ f)(x) = x + 10.

4. (g ◦ g)(x):
To find (g ◦ g)(x), we need to perform the composition of the functions g(x) and g(x).

First, let's find g(g(x)). We substitute g(x) into the function g(x), which gives us g(g(x)) = 1(g(x) + 5).

Now, let's substitute g(x) + 5 into the function g(x). We get g(g(x)) = 1(g(x) + 5) = 1((1(x + 5)) + 5) = 1(1(x + 5) + 5) = 1(1x + 10) = 1(x + 10) = x + 10.

Therefore, (g ◦ g)(x) = x + 10.

In summary:

1. (f ◦ f)(x) = x + 10.
2. (f ◦ g)(x) = x + 10.
3. (g ◦ f)(x) = x + 10.
4. (g ◦ g)(x) = x + 10.

Answer:

There are 120 probability ways to arrange the results because there are 12 rolls and each roll can be organised in 12 different ways.

There are 120 different layouts for the results. This is because there are 12 rolls and there are 12 possible arrangements for each roll. A 1, 2, 3, 4, 5, or 6 might appear on the first roll, and any of these six numbers could appear on the second roll. Applying this to the remaining 10 rolls yields a feasible layout of 12 x 12, which is equal to 120. In this example, two of the rolls need to land on 1, four need to land on 2, three need to land on 3, one need to land on 4, two need to land on 5, and none need to land on 6. Consequently, there are 120 different configurations that might be used.

Answer:

It would take you almost 17 days driving at 100 km/hour, 24 hours a day to ... Circumference of the Earth in inches: 1,577,727,360 inches.

Step-by-step explanation:

The orthogonal projection of f(x)=3x2+5x−6 onto the line L spanned by g(x)=3x2−5x+5 is:

h(x) = ag(x) = (111/306)(3x2−5x+5) = (37/102)(3x2−5x+5)

To find the orthogonal projection of f(x)=3x2+5x−6 onto the line L spanned by g(x)=3x2−5x+5, we need to find a scalar multiple of g(x) that is closest to f(x). That is, we need to find the projection of f(x) onto the line L.

Let h(x) be the orthogonal projection of f(x) onto the line L. Then, we have:

h(x) = ag(x)

where a is a scalar to be determined. We want h(x) to be as close to f(x) as possible, so we want the vector f(x) − h(x) to be orthogonal to g(x). That is,

〈f(x) − h(x), g(x)〉 = 0

Using the given inner product, we have:

〈f(x) − h(x), g(x)〉 = 〈f(x), g(x)〉 − 〈h(x), g(x)〉

Since h(x) = ag(x), we have:

〈h(x), g(x)〉 = a〈g(x), g(x)〉 = a(〈3x2−5x+5, 3x2−5x+5〉) = 34a(3x2−5x+5)

Thus, we need to find the value of a that minimizes the expression:

〈f(x), g(x)〉 − 〈h(x), g(x)〉 = 〈f(x), g(x)〉 − a〈g(x), g(x)〉

Substituting the given functions for f(x) and g(x), we get:

〈3x2+5x−6, 3x2−5x+5〉 − a〈3x2−5x+5, 3x2−5x+5〉

Expanding the inner products, we get:

9x4 − 34x3 + 10x2 − 15x − 30 − 9a(x2 − 10x + 17)

Collecting like terms, we get:

(9 − 9a)x4 + (−34 + 90a)x3 + (10 − 153a)x2 + (−15 + 85a)x − 30

For this expression to be minimized, its derivative with respect to a must be zero:

d/da [(9 − 9a)x4 + (−34 + 90a)x3 + (10 − 153a)x2 + (−15 + 85a)x − 30] = 0

Simplifying and solving for a, we get:

a = 111/306

Therefore, the orthogonal projection of f(x)=3x2+5x−6 onto the line L spanned by g(x)=3x2−5x+5 is:

h(x) = ag(x) = (111/306)(3x2−5x+5) = (37/102)(3x2−5x+5)

Answer: 80

Step-by-step explanation:

The area of the given rectangle is 64 sq. units

Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.

Given that, a rectangle ABCD plotted below.

C(4,4)

D(-8,0)

B(6,-2)

A(-6, -6)

Finding the length of sides,

We know that distance between two points = √(x₂-x₁)²+(y₂-y₁)²

Distance between C(4,4) and D(-8,0) = √(4-4)²+(0+8)² = √64 = 8

Distance between C(4,4) and B(6,-2) = √(4-4)²+(-2-6)² = √64 = 8

Distance between D(-8,0) and A(-6, -6) = √(-6+6)²+(0+8)² = √64 = 8

Since, all sides are equal, we can say that the rectangle is a square with side = 8 units

Area of a square = (side)² = 8² = 64

Hence, The area of the given rectangle is 64 sq. units

Answer:

180

Step-by-step explanation:

let x = total units of electricity after 250 units

the total units of electricity consumed can be determined using the formula below

80 + 7.3x = 1248

7.3x = 1248 - 80

7.3x = 1168

divide both sides of the equation by 7.3

x = 1168 / 7.3

x = 160

total electricity consumed = 160 + 20 = 180

The probability of drawing a seven and then a four when randomly drawing two cards without replacement is 0.0045 or approximately 0.45%.

The probability of drawing a seven and then a four when randomly drawing two cards without replacement can be calculated using the following steps:

First, we need to determine the total number of possible outcomes when drawing two cards from a standard deck of 52 cards without replacement. This can be found using the combination formula:

C(52,2) = 52! / (2! * (52-2)!) = 1,326

Next, we need to determine the number of favorable outcomes where we draw a seven and then a four.

There are four sevens and four fours in a deck of 52 cards, so the probability of drawing a seven on the first draw is 4/52. Since we are not replacing the card, there are now 51 cards left in the deck, and three of them are fours. Therefore, the probability of drawing a four on the second draw is 3/51.

The probability of drawing a seven and then a four is the product of the probabilities of drawing a seven on the first draw and a four on the second draw:

P(seven and then four) = (4/52) * (3/51) = 0.0045 or approximately 0.45%.

Therefore, the probability of drawing a seven and then a four when without replacement is 0.0045 or approximately 0.45%.

When rolling a dice twice, we can get 36 different combinations of the numbers, starting from (1,1),(1,2),(1,3),... up to (6,4),(6,5),(6,6).

From those combinations, only those where the second number rolled is not less than the first number are favorable outcomes.

Thus, the favorable outcomes are:

{(1,1),(1,2),(1,3),(1,4),(1,5),(1,6),(2,2),(2,3),(2,4),(2,5),(2,6),(3,3),(3,4),(3,5),(3,6),

(4,4),(4,5),(4,6),(5,5),(5,6),(6,6)}
