The surface area of the cone is 113.09 square units.

A three-dimensional object's surface area is the sum of all of its faces. Real-world applications of the concept of surface areas include wrapping, painting, and eventually building things to achieve the best possible design.

Given that the height of the cone is 3 units and the radius of the base is 4 units.

The surface area of the cone is calculated by the formula:-

SA = πrl + πr²

Slant height will be calculated as:-

l² = h² + r²

l² = 3 ² + 4²

l² = 25

l = 5 units

The surface area will be:-

SA = πrl + πr²

SA = ( πx 4 x 5 ) + ( π x 4² )

SA = 113.09 square units

Therefore, the surface area will be 113.09 square units.

The sides of the rectangle in question number 1 are 4.5 units and 13.5 units. The sides of the rectangle in question number 2 are 6 units and 12 units.

Let's call the width of the rectangle in question number one as "w". Since the length of the rectangle is three times as long as its width, the length can be represented as 3w.

The perimeter of the rectangle is 36 units, so if we add up the lengths of all four sides, we get:

2w + 2(3w) = 36

2w + 6w = 36

8w = 36

w = 4.5

So the width of the rectangle is 4.5 units. Since the length is three times the width, the length is 3 × 4.5 = 13.5 units. So the sides of the rectangle are 4.5 units and 13.5 units.

Let's call the width of the rectangle in question number 2 as "p". Since the length of the rectangle is twice as long as its width, the length can be represented as 2p.

The area of the rectangle is given as 72 square units, so we can use the formula for the area of a rectangle to find the value of p:

A = l × w

72 = 2p × p

72 = 2p²

36 = p²

p = 6

So the width of the rectangle is 6 units. Since the length is twice the width, the length is 2 × 6 = 12 units. So the sides of the rectangle are 6 units and 12 units.

Here's how you can use partial fraction decomposition to write (x^3 + 2x^2 + 3x + 4)/(x^2 + x - 2) as the sum of simpler terms:

Factor the denominator to simplify the expression: x^2 + x - 2 = (x - 1)(x + 2)

Write the partial fraction decomposition of the integrand as the sum of simpler terms: (x^3 + 2x^2 + 3x + 4)/(x^2 + x - 2) = A/(x - 1) + B/(x + 2) + Cx + D, where A, B, C, and D are constants.

Multiply both sides of the equation by (x^2 + x - 2) to find the values of A, B, C, and D: x^3 + 2x^2 + 3x + 4 = A(x + 2) + B(x - 1) + (Cx + D)(x^2 + x - 2)

Substitute x = 1 and x = -2 into the equation to find two equations for A, B, C, and D:

x = 1: 4 + 2 + 3 + 4 = 9 = A(-2) + B + (C + D)(-1)

x = -2: -8 - 4 + 6 - 8 = -16 = A(1) + B(-2) + (C - 2D)(4)

Solve the system of equations to find the values of A, B, C, and D:

A = 9/3, B = 5, C = -11/3, D = 7/3

So the partial fraction decomposition of (x^3 + 2x^2 + 3x + 4)/(x^2 + x - 2) is (9/3)/(x - 1) + (5)/(x + 2) - (11/3)x + (7/3).

Spinner 1 is divided into 6 congruent sections.

There are 3 red sections, 2 blue sections and 1 yellow section.

Therefore, the probability of spinning each of the three colors is:

    [tex]\bullet \quad \sf P(Y_1)=\dfrac{1}{6}[/tex]

Spinner 2 is divided into 3 sections of differing sizes.

The red section is half of the spinner. The blue and yellow sections are quarters of the spinner.

Therefore, the probability of spinning each of the three colors is:

    [tex]\bullet \quad \sf P(R_2)=\dfrac{1}{2}[/tex]

    [tex]\bullet \quad \sf P(B_2)=\dfrac{1}{4}[/tex]

The probability that both spinners both show yellow is:

[tex]\sf P(Y_1)\;and\;P(Y_2)=\dfrac{1}{6} \times \dfrac{1}{4}=\dfrac{1}{24}[/tex]

Therefore, the probability that both spinners show the same colour is:

The probability of the event is calculated by taking the probability of the event occurring 0.53, or about 0.03125.

A coin being flipped five times is an example of a Bernoulli trial, which is a type of experiment where the outcome can be either success or failure. The probability of success (a heads) is equal to the probability of failure (a tails). So, for this experiment, the probability of a heads is 0.5 and the probability of a tails is 0.5.

The event of a coin being flipped five times can be expressed as a set in roster notation as {HHHHT, HHHTH, HHTHH, HTHHH, THHHH, HHHTT, HHTTH, HTHHT, THHHT, HTTHH, TTHHH, HHTTT, HTTHT, THHTT, TTHHT, TTTHH, HTTTT, THTTT, TTHTT, TTTHT, TTTTH, TTTTT}.

The probability of the event is calculated by taking the probability of the event occurring (in this case, 0.5 for a heads and 0.5 for a tails) and multiplying it by the number of trials (in this case, 5). This gives us a probability of 0.53, or about 0.03125.

The approximations using the trapezoidal rule, midpoint rule, and Simpson's rule are 0.436904, 0.439881, and 0.439363, respectively.

(a) Trapezoidal Rule:

The trapezoidal rule approximates the definite integral as the sum of areas of trapezoids under the curve, connecting the function values at evenly spaced points within the interval of integration.

The formula for the trapezoidal rule is given by:

∫_a^b f(x) dx ≈ (b - a) * [f(a) + f(b)] / 2

For n = 4 subintervals, we can find the height of each trapezoid by evaluating the function at 0, 1/4, 1/2, 3/4, and 1.

∫_0^1 e^(−6x^2)dx ≈ (1 - 0) * [e^(-6 * 0^2) + e^(-6 * 1^2)] / 2 = (1 - 0) * [1 + e^(-6)] / 2 ≈ 0.436904

(b) Midpoint Rule:

The midpoint rule approximates the definite integral as the sum of areas of rectangles under the curve, using the function value at the midpoint of each subinterval as the height of each rectangle.

The formula for the midpoint rule is given by:

∫_a^b f(x) dx ≈ (b - a) * ∑ f(a + (b - a) * i / n) / n, where i = 1, 2, ..., n

For n = 4 subintervals, we can find the midpoints by evaluating the function at 1/8, 3/8, 5/8, and 7/8.

∫_0^1 e^(−6x^2)dx ≈ (1 - 0) * [e^(-6 * 1/8^2) + e^(-6 * 3/8^2) + e^(-6 * 5/8^2) + e^(-6 * 7/8^2)] / 4 ≈ 0.439881

(c) Simpson's Rule:

Simpson's rule approximates the definite integral as the sum of areas of parabolic curves under the curve, connecting the function values at three evenly spaced points within each subinterval.

The formula for Simpson's rule is given by:

∫_a^b f(x) dx ≈ (b - a) * [f(a) + 4 * ∑ f(a + (b - a) * i / (2n)) + 2 * ∑ f(a + (b - a) * i / n) + f(b)] / (6n)

For n = 4 subintervals, we can find the points by evaluating the function at 0, 1/4, 1/2, 3/4, and 1.

∫_0^1 e^(−6x^2)dx ≈ (1 - 0) * [e^(-6 * 0^2) + 4 * (e^(-6 * 1/4^2) + e^(-6 * 3/4^2)) + 2 * (e^(-6 * 1/2^2)) + e^(-6 * 1^2)] / (6 * 4) ≈ 0.439363

The distance between the two points S( -5, 7) to V(- 2, 4) is 3.5 units.

The distance formula between two points (x₁, y₁) and (x₂, y₂) is given by,

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex].

Given, We have to find the distance between the points S(- 5, 7) to V(-2, 4).

Therefore, [tex]|SV| =\sqrt{(- 2 + 5)^2 + (4 - 7)^2}[/tex].

[tex]|SV| =\sqrt{(3)^2 + (-3)^2}[/tex].

[tex]|SV| =\sqrt{9 + 9}[/tex].

|SV| = √18.

|SV| = 2√3.

The number of unique visitors to library in a month with following probabilities: P0X9)-04, P0X19)-07, P(0 X 29)-0.8, P(0≤x≤39)=0.9, P(0sX<49)-1 are;

a. P(X=50) = 0, since X can't be greater than 49 (according to the given information) and the probability of X being exactly 49 is 1.

b. P(10≤X≤19) = P(X=10) + P(X=11) + ... + P(X=19) = 0.07 - 0.04 = 0.03

c. P(20≤X≤29) = P(X=20) + P(X=21) + ... + P(X=29) = 0.8 - 0.07 = 0.73

d. P(X>39) = 1 - P(0≤X≤39) = 1 - 0.9 = 0.1

I determined the probabilities in the way I did by using the cumulative distribution function of a discrete random variable.

The cumulative distribution function (CDF) of a discrete random variable X is defined as:

CDF(x) = P(X≤x) = ∑P(X=x'), for all x' such that x' ≤ x

So, for each of the given ranges, I calculated the cumulative probability up to that range using the CDF definition and the individual probabilities of X being exactly each value within the range.
