Answer:

E. 360

Step-by-step explanation:

We have two boxes of 6in by 6in,

and 4 with 12in by 6in, so we just multiply to find the area and add them up

6 x 6 = 36 x 2 = 72

12 x 6 = 72 x 4 = 288,

add them up and we get 360.

The volume of each cylindrical shell can be calculated using the formula: V = 2πrhΔx.

To find the volume of the solid formed by rotating triangle AMT around MH, we'll use the method of cylindrical shells.

As we rotate triangle AMT around MH, we create cylindrical shells with height HT and radius corresponding to the distance between each point on the triangle and the line MH.

The volume of each cylindrical shell can be calculated using the formula: V = 2πrhΔx,

where r represents the radius.

h represents the height,

and Δx represents a small change in x.

In this case, the height h is equal to HT, which is 8 units.

To find the radius r, we need to consider the distance between each point on triangle AMT and the line MH.

Since HM has a length of 5 units, the radius r is equal to the perpendicular distance between the line MH and each point on triangle AMT.

To find the volume of the solid, we'll integrate the volumes of all the cylindrical shells. The limits of integration will depend on the x-values of triangle AMT.

Since the question does not provide the specific x-values or the shape of triangle AMT, we cannot proceed further to determine the volume accurately.

Please note that the diagram provided represents a right triangle MTH, where angle ZHM is 90 degrees, and side lengths HT and HM are given as 8 units and 5 units, respectively.

Triangle AMT is shown within the larger triangle MTH.

To ensure a zero cash flow in the portfolio, the writer needs to set up a portfolio that offsets the cash flow from selling the derivatives. The writer should have -3 underlying assets in the portfolio (meaning short sold assets)

The cash flow from selling 100 derivatives can be calculated as:

Cash Flow from selling derivatives = 100 * (Premium at time 0 - Expiry value)

Cash Flow from selling derivatives = 100 * (1.34 - 0.64) = 70

To offset this cash flow, the writer needs to include an equal and opposite cash flow from the underlying assets. Let's assume the writer buys ""x"" underlying assets.

Cash Flow from underlying assets = x * (Value at time 0 - Value at time 1)

Cash Flow from underlying assets = x * (36 - 57) = -21x

To make the cash flow from underlying assets equal to the cash flow from selling derivatives, we set up the equation:

-21x = 70

Solving this equation, we find:

x ≈ -3.33

Since the number of underlying assets must be an integer, we round -3.33 to the nearest integer, which is -3.

Therefore, the writer should have -3 underlying assets in the portfolio (meaning short sold assets).

given

The distance surrounding a closed-plane figure is its perimeter, or P.

P is equal to a plus b plus c, where a, b, and c are the lengths of the three sides, and let c be the third side's undetermined length.

P = 38 m, a = 13 m, and b = 18 m are the values provided. Now, to determine the third side's length c,

P = a + b + c

38m = 13m, 18m, and c

38 m = 31 m + c

38 m minus 31 m Equals 31 m minus 31 m plus c

7 m = 0 + c

7 m = c

8x11+88

Step-by-step explanation:

Answer: 80°; the supplementary angle to the 30° angle and ∠1 is a corresponding angle to the 70° angle this means that the supplementary angle to the 30° angle and ∠1 is a 70° angle therefore 30°+m ∠1+ 70° equals 180°. So, m ∠1= 180°.

Step-by-step explanation:

The measure of angle 1 should be 80 degrees.

Two angles whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line. Those two two angles are two pairs of supplementary angles.

Then its meaning; supplementary angles are aligned adjacent to each other, and their exterior sides will make a straight line.

The supplementary angle to the 30° angle and ∠1 is a corresponding angle to the 70° angle which means that the supplementary angle to the 30° angle and ∠1 is a 70° angle.

Therefore 30° + m ∠1 +  70° = 180°.

100 + m ∠1= 180°.

So, m ∠1= 80°.

Answer:

Step-by-step explanation:

We may not be able to fit 16 cases in the box because their combined volume will be greater than the box which will make it impossible.

The dimensions of the big box is given as:

Length= 26 cm

Breadth= 15 cm

Height= 20 cm

So its volume can be calculated by:

Volume= Length x Breadth x Height

Volume= 26 cm x 15 cm x 20 cm

Volume1= 7800 cm³

Now, the dimension of one disc case is given as:

Length= 1.6 cm

Breadth= 14.2 cm

Height= 19.3 cm

The volume of one disc case will be:

Volume= 1.6 cm x 14.2 cm x 19.3 cm

Volume= 438.496 cm³

So, volume of 16 disc cases= 16 X volume of one disc case

Volume2= 16 x 438.496 cm³

Volume2= 7015.936 cm³

Since Volume1 < Volume2

So, 16 disc cases cannot be fit into a box.

When a data value is converted to a standardized scale representing the number of standard deviations the data value lies from the mean, we call the new value a z-score or a standard score.

A z-score is a dimensionless quantity that represents the number of standard deviations an observation or data value is above or below the population mean. It is calculated by subtracting the mean from the observed value and then dividing the result by the standard deviation of the population. The resulting value is a measure of how far from the mean the observation falls, in terms of the standard deviation of the population.

Z-scores are useful in statistics because they allow us to compare observations or data values from different populations or distributions, even if they have different means and standard deviations. By converting each observation to a z-score, we can put them all on the same standardized scale, which makes it easier to compare and analyze them.

Answer:

77/15, -376/15

Step-by-step explanation:

We have two equations:

13x = -85 - y     (equation 1)

2x = -8 - y       (equation 2)

We can rewrite equation 1 as:

y = -85 - 13x

Substituting this expression for y into equation 2 gives:

2x = -8 - (-85 - 13x)

Simplifying this expression:

2x = 77 - 13x

Adding 13x to both sides:

15x = 77

Dividing by 15:

x = 77/15

Substituting this value of x into equation 1 gives:

y = -85 - 13(77/15) = -376/15

Therefore, the solution to the system of linear equations is:

x = 77/15, y = -376/15

So, the values of x and y separated by a comma are:

77/15, -376/15

The following statements are true:

1. During the first 10 days the professor's standard deviation was more than 0.

4. It is impossible to tell anything about the professor's standard deviation for the first 10 days.

6. Considering all 11 days, the professor's standard deviation was higher than the standard deviation of the first 10 days.

The standard deviation is a measure of how spread out a set of data is. In this case, the data is the prices of the value meals that the professor orders. If all 10 of the first meals cost $5.39, then the standard deviation would be 0.

This is because there is no variation in the data. However, on the 11th day, the professor orders a meal that costs $4.38. This adds variation to the data, which means that the standard deviation will be greater than 0.

Step-by-step explanation:

Let's write both fractions with the same denominator.  The LCD of 3 and 11 is 33.

7/11 = (7 * 3)/(11 * 3) = 21/33

The fractions 2/3 and 7/11 are equal to the fractions 22/33 and 21/33, respectively.

We need a fraction whose value is between 22/33 and 21/33.

We need a numerator between 21 and 22. Let's use 21.5 as the numerator.

The fraction 21.5/33 is between 2/3 and 7/11. In order not to have a decimal number as the numerator, we multiply the numerator and denominator of 21.5/33 by 2.
