Answer:

51.63m^3

Step-by-step explanation:

The figure is made up of a rectangle, triangle and a semi circle

Area of the figure = Area of triangle + rectangle + semicircle

Area of the triangle = 1/2 * base * height

Area of the triangle = 1/2 * 3 * 5

Area of the triangle = 15/2

Area of the triangle = 7.5m^3

Area of the rectangle = Length * Width

Area of the rectangle = 6 * 5

Area of the rectangle = 30m^2

Area of the semicircle = πr²/2

Area of the semicircle = π(3)²/2

Area of the semicircle = 3.14(9)/2

Area of the semicircle = 3.14 * 4.5

Area of the semicircle = 14.13m^2

The area = 30 + 14.13+7.5

Area of the figure = 51.63m^3

Answer:

51.63m²

Step-by-step explanation:

The events of randomly selecting a 5 first and randomly selecting an odd number from a bag containing numbered papers 1 through 6 are independent.

To determine whether two events are independent, we need to compare the probabilities of each event occurring separately and the probability of both events occurring together. In this case, the sample space consists of all possible outcomes when selecting two papers from the bag.

The probability of randomly selecting a 5 first is 1/6, as there is only one paper with the number 5 out of the six papers in the bag. The probability of randomly selecting an odd number is 3/6 since there are three odd-numbered papers (1, 3, and 5) out of the six papers.

To check for independence, we multiply the probabilities of the two events. (1/6) * (3/6) = 1/12, which is the probability of randomly selecting a 5 first and an odd number second. However, since the two events are replaced after each selection, the probability of selecting a 5 first does not affect the probability of selecting an odd number second.

Therefore, the events of randomly selecting a 5 first and randomly selecting an odd number are independent events because the probability of one event occurring does not affect the probability of the other event occurring.

y=-4x+3

Step-by-step explanation:

same slope different y intercept.

a.) The weights, ω1 + ω2 + ω3 = 1. b.) The weights, V[Y_bar ω] = ω1²V[Y1] + ω2²V[Y2] + ω3²V[Y3] = ω1²σ² + ω2²σ² + ω3²σ² = σ²(ω1² + ω2² + ω3²). To estimate the expectation μ, we propose combining three independent and identically distributed random variables Y1, Y2, and Y3 using a weighted average, Y_bar ω = ω1Y1 + ω2Y2 + ω3Y3.

(a) The weights ω1, ω2, and ω3 need to satisfy the condition ω1 + ω2 + ω3 = 1 for Y_bar ω to be an unbiased estimator for μ. The expectation E[Y_bar ω] is calculated as E[Y_bar ω] = ω1E[Y1] + ω2E[Y2] + ω3E[Y3] = ω1μ + ω2μ + ω3μ = (ω1 + ω2 + ω3)μ. For Y_bar ω to be an unbiased estimator for μ, its expectation should equal μ. Therefore, ω1 + ω2 + ω3 = 1.

(b) The variance V[Y_bar ω] can be calculated as V[Y_bar ω] = V[ω1Y1 + ω2Y2 + ω3Y3]. Since Y1, Y2, and Y3 are independent, the variance of their sum is the sum of their variances. Therefore, V[Y_bar ω] = ω1²V[Y1] + ω2²V[Y2] + ω3²V[Y3] = ω1²σ² + ω2²σ² + ω3²σ² = σ²(ω1² + ω2² + ω3²). The variance of Y_bar(ω) can be calculated, and by applying the condition from (a), the set of weights that minimize the variance can be determined.

To minimize the variance, we can apply the condition from (a), ω1 + ω2 + ω3 = 1, and use a technique called Lagrange multipliers. By introducing the Lagrange multiplier λ, we form the Lagrangian L = σ²(ω1² + ω2² + ω3²) + λ(ω1 + ω2 + ω3 - 1). Taking partial derivatives with respect to ω1, ω2, ω3, and λ, we can solve the equations to find the set of weights that minimize the variance. The specific values will depend on the given values of σ² and the constraints imposed by the problem.

The equation could be used to solve for charles' rate if it is represented by x is 2x=54.

In the given question wehave to find the equation could be used to solve for charles' rate if it is represented by x.

Bill riding a bicycle at an average rate of 9 mph.

Charles' rate is x.

So the relative rate = x−9 mph

Distance traveled by Bill in 4 hours = 9*4 =36 mph

Charles' overtook Bill in 2 hours. So

Relative Rate = Distance/Time

x−9=36/2

Multiply by 2 on both side. We get

2(x−9)=36

Simplifying

2x−18=36

Add 18 on both side, we get

2x=36+18

2x=54

Hence, the equation could be used to solve for charles' rate if it is represented by x is 2x=54.

The decreased value is 12, 082.86.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. With the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

Decrease £14132.77 by 14.5%

So, the decrease value is

= 14132 - 14132 x 14.5/100

= 14132 - 14132 x 0.145

= 14132 - 2,049.14

The perimeter of the figure 1 is 36 centimeter.

From the given figure,

1) Missing side = 8-5 = 3 cm

Here, perimeter = 8+10+5+7+3+3 = 36 cm

2) Missing side = 12-8 = 4 cm

Missing side = 9-7 = 2 cm

Here, perimeter = 12+7+4+8+9+2

= 42 cm

3) Missing side = 60-40 = 20 mm

Missing side = 30+15 = 45 mm

Perimeter = 60+15+40+30+20+45

= 210 mm

4) Missing side = 71/2 + 11/2

= 9 m

Missing side = 4+2 = 6m

Perimeter = \(7\frac{1}{2}\) + 4+ \(1\frac{1}{2}\) +2+9+6

= 9+4+2+9+6

= 30 m

Therefore, the perimeter of the figure 1 is 36 centimeter.

If you apply the law of detachment to the conditional "if you have a square, then you have a rectangle," you can conclude that if you have a square, you must also have a rectangle.

This is because the law of detachment states that if a conditional statement is true and the antecedent (the "if" clause) is also true, then the consequent (the "then" clause) must also be true.

In this case, the conditional "if you have a square, then you have a rectangle" is true because all squares are rectangles (since a rectangle is defined as a geometric figure with four straight sides and four right angles). Therefore, if you have a square, you can conclude that you also have a rectangle.

The composite functions when evaluated are (f + g)(x) = 3x² - 8x + 14, (f + g)(x) = x² - 8x - 4 and (fg)(x) = (2x² - 8x + 5)(x² + 9)

From the question, we have the following functions that can be used in our computation:

f(x) = 2x² - 8x + 5

g(x) = x² + 9

Using the above equations as a guide, we have the following:

(f + g)(x) = 2x² - 8x + 5 + x² + 9

(f + g)(x) = 3x² - 8x + 14

(f - g)(x) = 2x² - 8x + 5 - x² - 9

(f + g)(x) = x² - 8x - 4

(fg)(x) = (2x² - 8x + 5)(x² + 9)

The limit of the given function is DNE (does not exist).

To find the limit of a function, we need to evaluate the function as x approaches a certain value. In this case, x is approaching infinity. As x gets larger and larger, the value of x2 also gets larger and larger. This means that the value of sqrt x2 + 11 will also get larger and larger, approaching infinity.

Since the function is approaching infinity, the limit does not exist. We can write this as:

lim x?? sqrt x2 + 11 = DNE

In conclusion, the limit of the given function does not exist and we can write the answer as DNE. This is because as x approaches infinity, the value of sqrt x2 + 11 also approaches infinity. Therefore, the limit does not exist.
