Answer:

Step-by-step explanation:

Triangle MNP is a right triangle with the following values:

Interior angles of a triangle sum to 180°. Therefore:

m∠M + m∠N + m∠P = 180°

m∠M + 58° + 90° = 180°

m∠M + 148° = 180°

m∠M = 32°

To find the measures of sides MN and NP, use the Law of Sines:

\(\boxed{\begin{minipage}{7.6 cm}\underline{Law of Sines} \\\\$\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}$\\\\\\where:\\ \phantom{ww}$\bullet$ $A, B$ and $C$ are the angles. \\ \phantom{ww}$\bullet$ $a, b$ and $c$ are the sides opposite the angles.\\\end{minipage}}\)

Substitute the values into the formula:

\(\dfrac{MN}{\sin P}=\dfrac{NP}{\sin M}=\dfrac{PM}{\sin N}\)

\(\dfrac{MN}{\sin 90^{\circ}}=\dfrac{NP}{\sin 32^{\circ}}=\dfrac{8}{\sin 58^{\circ}}\)

Therefore:

\(MN=\dfrac{8\sin 90^{\circ}}{\sin 58^{\circ}}=9.43342722...\)

\(NP=\dfrac{8\sin 32^{\circ}}{\sin 58^{\circ}}=4.99895481...\)

To find the perimeter of triangle MNP, sum the lengths of the sides.

\(\begin{aligned}\textsf{Perimeter}&=MN+NP+PM\\&=9.43342722...+4.99895481...+8\\&=22.4323820...\\&=22.43\; \sf units\; (2\;d.p.)\end{aligned}\)

Ordered pair (0, 6) and  (2, 7)  satisfy both inequalities in the system and are solutions to the system.

To identify the graph that represents the given system of inequalities y > x + 5 and y ≥ 2x + 3, we need to graph the individual inequalities and find the region where they overlap.

When we plot the graph of inequality separately:

    2. y ≥ 2x + 3:

The overlapping shaded region represents the solution to the system of inequalities.

To find two ordered pairs that are solutions to the system, we can choose any points within the overlapping region. Let's select two points:

Step-by-step explanation:

Lisa was 48 inches tall when she was younger. She grew 2 1/2 inches per year. Lisa

is now 63 inches tall. How many years did Lisa grow for?

a. 5

b. 6

c. 7

d. 8

2 1/2=5/2

48+(5/2*5)=48+12.5=60.5

48+(5/2*6)=48+15=63

therefore it is answer b

a).  2^38 bytes of memory

b). 12 bits

c). The maximum number of entries in the single-level page table would be 2^38.

d). The size would be 2^38 * 4KB, which equals 2^20 pages.

e). The maximum number of entries it can have depends on the remaining bits of the logical address.

f). The amount of bits required to denote an index into the inner page table is obtained by subtracting the offset and outer page index bits from the logical address.

a. To address a physical memory size of 128GB (2^37 bytes), a 64-bit architecture would require 38 bits for the logical address, allowing access to a maximum of 2^38 bytes of memory.

b. Given that the page size is 4KB (2^12 bytes), 12 bits would be needed to specify the displacement into a page. This means that the lower 12 bits of the logical address would be used for page offset or displacement.

c. With a single-level page table, the maximum number of entries would be equal to the number of possible logical addresses. In this case, since the logical address requires 38 bits, the maximum number of entries in the single-level page table would be 2^38.

d. The size of the single-level page table is determined by the number of entries it contains. Since each entry maps to a page of size 4KB, the size of the single-level page table can be calculated by multiplying the number of entries by the size of each entry. In this case, the size would be 2^38 * 4KB, which equals 2^20 pages.

e. For a two-level page table, the size of the outer page table is determined by the number of entries it can contain. Since the outer page table uses 4KB pages, the maximum number of entries it can have depends on the remaining bits of the logical address. The number of bits used for the index into the outer page table is determined by subtracting the bits used for the inner page index and the offset from the total number of bits in the logical address.

f. The number of bits used to specify an index into the inner page table can be determined by subtracting the bits used for the offset and the bits used for the outer page index from the total number of bits in the logical address. The remaining bits are then used to specify the index into the inner page table.

Line p must be drawn so that it can lie in the same plane as line 1

Line p must be drawn in a way that allows it to lie in the same plane as line l.

In geometry, a plane extends in two dimensions indefinitely. There is no width. In coordinate geometry, a plane can be seen as an example. The positions of points in a plane are determined by their coordinates.

A plane is a flat, two-dimensional surface in mathematics that extends indefinitely. A plane is a two-dimensional analog that can incorporate three dimensions of space, a line, and a point.

Given two planes A and B,

and line l is in plane A,

to draw a line parallel to l,

"Two lines in the same plane, which are equally spaced apart and never cross" are parallel lines.

In order for a new line, p, to lie in the same plane as line l, it must be drawn parallel to line l.

Plane A contains line l.

Thus, plane A is where the line p must be drawn.

Step-by-step explanation:

There are 24 different ways we can draw two red, three green, and two purple balls if the balls are considered distinct.

To determine the number of ways we can draw the balls, we can use the concept of permutations. Since the balls are considered distinct, the order in which they are drawn matters.

First, let's consider the red balls. We need to choose 2 out of the available 2 red balls, so the number of ways to choose them is 2P2 = 2! = 2.

Next, let's consider the green balls. We need to choose 3 out of the available 3 green balls, so the number of ways to choose them is 3P3 = 3! = 6.

Finally, let's consider the purple balls. We need to choose 2 out of the available 2 purple balls, so the number of ways to choose them is 2P2 = 2! = 2.

To find the total number of ways we can draw the balls, we multiply the number of ways for each color: 2 * 6 * 2 = 24.

Therefore, there are 24 different ways we can draw two red, three green, and two purple balls if the balls are considered distinct.

The work done in stretching the spring from its natural length to 1.1 feet beyond its natural length is 6.125 foot-pounds.

The work done in extending a spring is given by the formula: W = (1/2)kx^2, where W is the work done, k is the spring constant, and x is the displacement from the natural length of the spring.

First, we need to find the spring constant k. Since a force of 5 pounds is required to hold the spring stretched 0.6 feet beyond its natural length, we can use the formula k = F/x to find k:

k = F/x = 5/0.6 = 8.33 pounds/foot

Now, we can find the work done in stretching the spring from its natural length to 1.1 feet beyond its natural length:

W = (1/2)kx^2 = (1/2)(8.33)(0.5^2) = 6.125 foot-pounds.

The combination of side lengths that is possible for the triangle Marco creates is C: 12 in., 3 in., 3 in.

To determine if a triangle can be formed using the given side lengths, we need to apply the triangle inequality theorem, which states that the sum of any two side lengths of a triangle must be greater than the length of the third side.

In combination A (1 in., 9 in., 8 in.), the sum of the two smaller sides (1 in. + 8 in.) is 9 in., which is not greater than the length of the remaining side (9 in.). Therefore, combination A is not possible.

In combination B (3 in., 5 in., 10 in.), the sum of the two smaller sides (3 in. + 5 in.) is 8 in., which is not greater than the length of the remaining side (10 in.). Hence, combination B is not possible.

In combination C (12 in., 3 in., 3 in.), the sum of the two smaller sides (3 in. + 3 in.) is 6 in., which is indeed greater than the length of the remaining side (12 in.). Thus, combination C is possible.

In combination D (2 in., 8 in., 8 in.), the sum of the two smaller sides (2 in. + 8 in.) is 10 in., which is equal to the length of the remaining side (8 in.). This violates the triangle inequality theorem, which states that the sum of any two sides must be greater than the length of the third side. Therefore, combination D is not possible.

Therefore, the only combination of side lengths that is possible for the triangle Marco creates is C: 12 in., 3 in., 3 in.

The Fisher information for a Pareto(α) distribution is I(α) = nα² / (α - 1)².

To determine the Fisher information for a sample from a Pareto(α) distribution, follow these steps:

1. Recall the Pareto(α) probability density function (PDF): f(x) = αxᵃ⁺¹), where x ≥ 1 and α > 0.
2. Compute the log-likelihood function, L(α) = ln(f(x1,...,xn)) = ∑ ln(α) - (α+1)ln(xi) for i = 1 to n.
3. Differentiate L(α) with respect to α: dL/dα = ∑ (1/α) - ln(xi).
4. Differentiate dL/dα again: d²L/dα² = -∑ (1/α²).
5. The Fisher information is the negative expectation of the second derivative: I(α) = -E(d²L/dα²).
6. Apply the Pareto(α) distribution's expectation: I(α) = nα² / (α - 1)².

To construct a model for the amount of Trioxin remaining in the swamp t days after it was dumped, we can use the exponential decay model:

A(t) = A₀ * e^(-kt),

where A(t) represents the amount of Trioxin remaining at time t, A₀ represents the initial amount of Trioxin dumped, k is the decay constant, and e is the base of the natural logarithm.

Let's use the given data points to solve for the parameters A₀ and k:

At t = 4 days: A(4) = 44.4 barrels

At t = 7 days: A(7) = 20.4 barrels

From these equations, we can set up a system of equations:

A₀ * e^(-4k) = 44.4, ----(1)

A₀ * e^(-7k) = 20.4. ----(2)

Divide equation (2) by equation (1) to eliminate A₀:

(e^(-7k)) / (e^(-4k)) = 20.4 / 44.4

e^(-7k + 4k) = 0.4595

e^(-3k) = 0.4595

Now, take the natural logarithm of both sides:

-3k = ln(0.4595)

k = ln(0.4595) / (-3)

Substitute the value of k back into equation (1) to solve for A₀:

A₀ * e^(-4 * ln(0.4595) / (-3)) = 44.4

A₀ * e^(4 * ln(0.4595) / 3) = 44.4

A₀ = 44.4 / e^(4 * ln(0.4595) / 3)

Now, we have the model for the amount of Trioxin remaining in the swamp t days after it was dumped:

A(t) = (44.4 / e^(4 * ln(0.4595) / 3)) * e^(-kt)

Now we can use this model to answer the questions:

According to the model, the amount of Trioxin initially dumped into the swamp is given by A₀:

A₀ = 44.4 / e^(4 * ln(0.4595) / 3)

Calculate A₀ and round to one decimal place.

To find the rate at which the amount of Trioxin is decreasing exactly 4 days after it was dumped, we can take the derivative of A(t) with respect to t and evaluate it at t = 4:

dA/dt = -A₀ * k * e^(-kt)

Rate of decrease at t = 4: -A₀ * k * e^(-4k)

Calculate this rate and round to one decimal place.

To find the number of days it takes for the amount of Trioxin in the swamp to drop to 2 barrels, we need to solve the equation A(t) = 2 for t:

(44.4 / e^(4 * ln(0.4595) / 3)) * e^(-kt) = 2

Solve this equation for t and round to one decimal place.

Based on the given mean delivery time of 10:28am and the standard deviation of 0:55 mins, the estimated times within which 95% of the deliveries are made is (a) between 8:38 am and 12:18 pm.

To calculate this interval, we need to use the z-score formula, where we find the z-score corresponding to the 95th percentile, which is 1.96. Then, we multiply this z-score by the standard deviation and add/subtract it from the mean to get the upper and lower bounds of the interval.

The upper bound is calculated as 10:28 + (1.96 x 0:55) = 12:18 pm, and the lower bound is calculated as 10:28 - (1.96 x 0:55) = 8:38 am.

Therefore, we can conclude that the interval between 8:38 am and 12:18 pm represents the estimated times within which 95% of the deliveries are made based on the given mean delivery time and standard deviation.
