Answer: 16

Step-by-step explanation:

Assume that this number is x:

When seven more than this number is doubled, the result is 46. In formula form that would be:

2 * (7 + n) = 46

Solving this formula:

2 * ( 7 + n) = 46

7 + n = 46/2

n = 46/2 - 7

n = 16

Answer:

3375 in³

Step-by-step explanation:

Volume of a cube = a³ ; where a = edge of the cube

Length of each face = edge of cube = 15 inches

Volume of cube = 15³

Volume of cube = 15 inch * 15 inch * 15 inch

Volume of cube = 3375 in³

Answer:

10% probability that the number is greater than 2, then P

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

Event A: Number greater than 2.

Event B: Letter P.

These events are independent, so:

\(P(A \cap B) = P(A) \times P(B)\)

P(A)

There are 5 numbers.

3, 4 or 5, that is, 3 numbers greater than 2.

3/5 = 0.6. So P(A) = 0.6.

P(B)

6 letters, one of which is P. So

P(B) = 1/6 = 0.1667.

What is the probability the number is greater than 2, then P?

\(P(A \cap B) = P(A) \times P(B) = 0.6 \times 0.1667 = 0.1\)

10% probability that the number is greater than 2, then P

Answer:

Solution,

Onions less than 60 grams = 2 --> Pickling

Onions greater than 120 grams = 5 + 3 = 8 --> Market

Onions between 60 and 120 = 13---> Processing

Total frequency = 2 + 8 + 13 = 23

Now,

\(x = \frac{13}{23} \times 360\)

\(x = 203.48\)

\(x = 203.5\)

Good luck on your assignment...

Answer:

x=190°

Step-by-step explanation:

find the frequency of the given numbers dividing by their numbers

onions less than 60g=(2+2/2)=²/9

onions greater than 120g=(5+3/2)= 4 (4+3/2). =3.5/9

To convert into degrees so that they can fit in the bar graph multiply the frequencies by 360 that is:

In case (a), where w1 = 0.8, w2 = 0.2, and the correlation coefficient p = 0.6, the portfolio's expected return and standard deviation can be determined. In case (b), where w1 = 0.6, w2 = 0.4, and the correlation coefficient rho = 0, the portfolio's expected return and standard deviation can be calculated. Lastly, in case (c), where w1 = 0.2, w2 = 0.8, and the correlation coefficient rho = -0.6, the portfolio's expected return and standard deviation can be computed.

(a) To calculate the expected return of the portfolio, we use the formula E(rp) = w1 * E(r1) + w2 * E(r2). Substituting the given values, we have E(rp) = 0.8 * 10% + 0.2 * 12% = 10.4%.

To calculate the standard deviation of the portfolio, we use the formula σp = sqrt(w1^2 * σ1^2 + w2^2 * σ2^2 + 2 * w1 * w2 * p * σ1 * σ2). Substituting the given values, we have σp = sqrt((0.8^2 * 18%^2) + (0.2^2 * 22%^2) + (2 * 0.8 * 0.2 * 0.6 * 18% * 22%)) ≈ 16.8%.

(b) Using the same formulas, for w1 = 0.6, w2 = 0.4, and rho = 0, we find E(rp) = 0.6 * 10% + 0.4 * 12% = 10.4%, and σp = sqrt((0.6^2 * 18%^2) + (0.4^2 * 22%^2)) ≈ 15.6%.

(c) For w1 = 0.2, w2 = 0.8, and rho = -0.6, we have E(rp) = 0.2 * 10% + 0.8 * 12% = 11.2%, and σp = sqrt((0.2^2 * 18%^2) + (0.8^2 * 22%^2) + (2 * 0.2 * 0.8 * -0.6 * 18% * 22%)) ≈ 19.7%.

In summary, the expected returns and standard deviations of the two-stock portfolio can be calculated using the given weights and correlation coefficients for each condition.

- x - 4 = - x - 4

Since both sides are equal then the equation has infinitely many solutions

The area between the curves is 0 square units. To find the area between the curves y = 5 and y = (-1)² - 4, we need to determine the points of intersection and calculate the definite integral of the difference between the two functions over that interval.

The area between the curves is given in square units. To find the area between the curves, we first set the two equations equal to each other and solve for y:

5 = (-1)² - 4

Simplifying, we have:

5 = 1 - 4

5 = -3

Since the equation is not true, it means that the two curves y = 5 and y = (-1)² - 4 do not intersect. As a result, there is no area between the curves.

Similar triangles are triangles that have the same shape, but their sizes may be same or different. In other words, if two triangles are similar, then their corresponding angles are congruent and corresponding sides are in equal proportion. The similarity of triangles are denoted by ‘~’ symbol

AA (or AAA) or Angle-Angle Similarity

If any two angles of a triangle are equal to any two angles of another triangle, then those two triangles are similar to each other.

SAS or Side-Angle-Side Similarity

Answer:

10 Km/h

Step-by-step explanation:

Let the speed of the container ship be y

The speed of the aircraft = y + 5

Next, we shall determine the time taken by the aircraft to travel 450 Km. This can be obtained as follow:

Speed of aircraft (Sₐ) = y + 5

Distance travelled (dₐ) = 450 Km

Time for aircraft (tₐ) =?

Speed = distance / time

Sₐ = dₐ / tₐ

y + 5 = 450 / tₐ

Cross multiply

(y + 5) × tₐ = 450

Divide both side by (y + 5)

tₐ = 450 / (y + 5)

Finally, we shall determine the speed of the carrier. This can be obtained as follow:

Speed of container ship (S꜀) = y

Distance travelled (d꜀) = 300 Km

Time for container ship (t꜀) = Time for aircraft (tₐ)

Time for aircraft (tₐ) = 450 / (y + 5)

t꜀ = tₐ

t꜀ = 450 / (y + 5)

Speed = distance / time

S꜀ = d꜀ / t꜀

y = 300 ÷ 450 / (y + 5)

y = 300 × (y + 5) / 450

y = (300y + 1500) / 450

Cross multiply

450y = 300y + 1500

Collect like terms

450y – 300y = 1500

150y = 1500

Divide both side by 150

y = 1500 / 150

y = 10 Km/h

Thus, the speed of the container ship is 10 Km/h.

S is not a solution for the Black-Scholes PDE because it does not satisfy the boundary conditions required for the option pricing problem.

The Black-Scholes partial differential equation (PDE) is used to model the behavior of stock prices and is a key tool in options pricing. It is given by:

where C is the price of a European call option, S is the underlying asset price, σ is the volatility, r is the risk-free interest rate, and t is time.

In order to solve for the price of the option, we need to impose boundary conditions. Specifically, the value of the option at expiry should be equal to the payoff of the option. For a European call option, the payoff is max(S-K,0), where K is the strike price. Therefore, we need to impose the boundary condition C(S,t) = max(S-K,0) as S approaches infinity.

However, if we substitute S into the Black-Scholes PDE, we find that it does not satisfy this boundary condition. For example, if we set C(S,t) = S, then the PDE reduces to:

Which is clearly not true. Therefore, S is not a solution for the Black-Scholes PDE.

The probability that a junior bio major who has taken statistics has also taken a computer course is 13.46%.

We are trying to find the probability that a junior bio major who has taken a statistics course has also taken a computer course. This is referred to as the conditional probability, denoted as P(computer | statistics).

To calculate this, we can use the formula:

P(computer | statistics) = P(computer and statistics) / P(statistics)

This formula states that the probability of a junior bio major taking a computer course given that they have taken a statistics course is equal to the probability of them taking both a computer and statistics course divided by the probability of them taking only a statistics course.

The information given in the problem is as follows:

P(statistics) = 52%

P(computer) = 23%

P(computer and statistics) = 7%

So we can plug these values into the formula to calculate the conditional probability:

P(computer | statistics) = P(computer and statistics) / P(statistics) = 7% / 52% = 0.1346153846153846 or 13.46%

Therefore, the probability that a junior bio major who has taken statistics has also taken a computer course is 13.46%.

One cannot conclude that watching more tv causes lower gpa or vice versa based solely on the correlation between the two variables.

if the correlation between tv viewing and gpa were significant, then the only valid conclusion one can draw from these data is that there is a relationship between tv viewing and gpa.

a significant correlation indicates that there is a strong association between the two variables - in this case, tv viewing and gpa. however, it's important to note that correlation does not imply causation. it's possible that there is a third variable, such as study habits or motivation, that is influencing both tv viewing and gpa.

in order to establish causation, further research would be needed to determine the direction of the relationship and to control for other variables that could be impacting both tv viewing and gpa.
