Step-by-step explanation:

outliers can be neglected especially when working out the mean

Therefore, The statement that "outliers are extreme values above or below the mean that require special consideration" is True.

Explanation:
Outliers are extreme values that lie significantly above or below the mean. They have special considerations because they can affect the interpretation of the mean and standard deviation. For instance, if an outlier is included in the dataset, the mean will be different from when it is excluded, making the mean unreliable. Therefore, outliers should be examined carefully to determine if they represent a genuine value or an error.

Step-by-step explanation:

The law of cosine helps us to know the third side of a triangle when two sides of the triangle are already known. The value of x is 117.8°. thus, the correct option is A.

The law of cosine helps us to know the third side of a triangle when two sides of the triangle are already known the angle opposite to the third side is given. It is given by the formula,

\(Cos(\theta) = \dfrac{a^2+b^2-c^2}{2ab}\)

where

c is the third side of the triangle

a and b are the other two sides of the triangle,

and θ is the angle opposite to the third side, therefore, opposite to side c.

As per the law of cosine, the measure of angle x can be written as,

\(Cos(x) = \dfrac{12^2+5^2-15^2}{2(5)(12)}\\\\Cos(x) = \dfrac{-56}{120}\\\\x = 117.8^o\)

Answer:

70/2

Step-by-step explanation:

We have a population of 200 people

Growth rate = 2%

How long it will take for the population to double

Double the population = 2× 200 = 400

The formula for Exponential growth =

y = a(1 + r)^t

y = Value at time t = 400

a = Initial value = 200

r = 2% = 0.02

t = ?

Hence:

400 = 200 ( 1 + 0.02)^t

Divide both sides by 200

400/200 = 200 ( 1 + 0.02)^t/200

2 = (1.02)^t

Take logarithm of both sides

log 2 = log(1.02)^t

log 2 = t log 1.02

t = log 2/log 1.02

t = 35.003417942

Approximately t = 35

We have so many formula to calculate doubling time

t = 70/Growth rate

From the above question

Growth rate = 70/2%

= 35

Therefore, the equation that we use to calculate how long it will take for the population to double to 400 people is 70/2

The value of x in the parallel line is as follows:

1. x = 50

2. x = 55

3. 102 - 2v

When parallel lines are cut by a transversal line, angle relationships are formed such as alternate interior angles, alternate exterior angles, corresponding angles, vertically opposite angles, linear angles etc.

Therefore, let's use the angle relationship to find the value of x as follows:

1.

m∠1 = m∠8(alternate interior angles)

2x + 25 = x + 75

2x - x = 75 - 25

x = 50

2.

m∠2 = m∠6(corresponding angles)

3x - 10 = 2x + 45

3x - 2x = 45 + 10

x = 55

3.

m∠3 + m∠8 = 180(same side interior angles)

4v - 31 + 2x + 7 = 180

2x = 180 + 31 - 7 - 4v

2x = 204 - 4v

x = 102 - 2v

When 100 ft of rope is out, the rate at which the boat is approaching the dock is 0 ft/min which means the boat is not moving towards the dock at that moment.

Let x represent the horizontal distance between the boat and the dock (in feet).

Let y represent the vertical distance between the boat and the pulley (in feet).

Since the rope is attached to the front of the boat, which is 10 feet below the level of the pulley, we have y = 10 ft.

The rate of change of the length of the rope, which is related to the distance between the boat and the dock, is dx/dt = 12 ft/min.

We want to find the rate at which the boat is approaching the dock, which is the rate of change of x with respect to time (dx/dt) when 100 ft of rope is out.

Now, let's set up the similar triangles between the boat, the pulley, and the dock.

x / y = (x + 100) / 100

Now, we can differentiate both sides of this equation with respect to time t:

d(x/y)/dt = d((x + 100) / 100)/dt

To solve for dx/dt, we need to differentiate x/y and (x + 100)/100 with respect to time.

Using the quotient rule, we have:

(dx/dt × y - x × dy/dt) / (y²) = (1/100) × (dx/dt)

Substituting y = 10 and dy/dt = 0 (since the pulley is fixed), we get:

(dx/dt × 10 - x × 0) / (10²) = (1/100) × (dx/dt)

10 × dx/dt = (1/100)×(dx/dt)

10 × dx/dt - (1/100) × dx/dt = 0

(1000/100 - 1/100) × dx/dt = 0

The cpk for this process is 0.5.

To calculate the cpk for this process, we first need to calculate the process capability index (cp) using the formula:
cp = (USL - LSL) / (6 × sigma)
where USL is the upper specification limit (48), LSL is the lower specification limit (30), and sigma is the process standard deviation (4).
cp = (48 - 30) / (6 × 4)
cp = 18 / 24
cp = 0.75
Next, we can calculate the cpk using the formula:
cpk = min[(USL - mean) / (3 × sigma), (mean - LSL) / (3 × sigma)]
cpk = min[(48 - 42) / (3 × 4), (42 - 30) / (3 × 4)]
cpk = min[6 / 12, 12 / 12]
cpk = min[0.5, 1]

To find the area enclosed by the closed curve obtained by joining the ends of the spiral r = 3θ, 0 ≤ θ ≤ 2.9, with a straight line segment, we need to break down the problem into two parts: the area enclosed by the spiral and the area enclosed by the straight line segment. Answer : Total Area ≈ (2.9)^3 + 37.905

1. Area enclosed by the spiral:

The equation r = 3θ represents a spiral. We can use polar coordinates to find the area enclosed by the spiral. The formula for the area enclosed by a polar curve is given by A = (1/2) ∫[θ1, θ2] r^2 dθ.

In this case, the spiral is given by r = 3θ and the range of θ is 0 to 2.9. Therefore, the area enclosed by the spiral is:

A_spiral = (1/2) ∫[0, 2.9] (3θ)^2 dθ

Simplifying the expression:

A_spiral = (1/2) ∫[0, 2.9] 9θ^2 dθ

A_spiral = (1/2) * 9 * ∫[0, 2.9] θ^2 dθ

Integrating:

A_spiral = (1/2) * 9 * [θ^3/3] evaluated from 0 to 2.9

A_spiral = (1/2) * 9 * [(2.9)^3/3 - 0^3/3]

A_spiral ≈ 9 * [(2.9)^3/9]

A_spiral ≈ (2.9)^3

2. Area enclosed by the straight line segment:

Since the straight line segment connects the ends of the spiral, it forms a triangle. The area of a triangle can be calculated using the formula A_triangle = (1/2) * base * height.

The base of the triangle is the distance between the two ends of the spiral, which is equal to the radius at θ = 2.9: r = 3(2.9) ≈ 8.7.

The height of the triangle is the difference in radii at the ends of the spiral: height = 3(2.9) - 0 = 8.7.

Therefore, the area enclosed by the straight line segment is:

A_line_segment = (1/2) * 8.7 * 8.7 = 37.905

Finally, to find the total area enclosed by the closed curve, we add the area of the spiral and the area of the straight line segment:

Total Area = A_spiral + A_line_segment

Total Area ≈ (2.9)^3 + 37.905

The arc length of O A is 10.192 ft, the arc length of OB is 16.529 ft, the arc length of C is 2.065 ft, and the arc length of OD is 8.263 ft.

To find the arc length of a circle with central angle θ and radius r, we use the formula L = rθ, where L is the length of the arc.

For O A, the radius is given as 4 ft, and the central angle is given as 146°. We need to convert the central angle from degrees to radians to use the formula for arc length:

θ = 146° * π/180 ≈ 2.548 radians

Now we can plug in the values into the formula to get the arc length:

L = 4 ft * 2.548 = 10.192 ft

Therefore, the arc length of O A is 10.192 ft.

For OB, the radius is given as 6.491 ft, and we need to find the arc length for a central angle of 146°:

θ = 146° * π/180 ≈ 2.548 radians

= 6.491 ft * 2.548 = 16.529 ft

Therefore, the arc length of OB is 16.529 ft.

For C, the radius is given as 0.811 ft, and we need to find the arc length for a central angle of 146°:

θ = 146° * π/180 ≈ 2.548 radians

L = 0.811 ft * 2.548 = 2.065 ft

Therefore, the arc length of C is 2.065 ft.

For OD, the radius is given as 3.2410 ft, and we need to find the arc length for a central angle of 146°:

θ = 146° * π/180 ≈ 2.548 radians

L = 3.2410 ft * 2.548 = 8.263 ft

Therefore, the arc length of OD is 8.263 ft.

In summary, the arc length of O A is 10.192 ft, the arc length of OB is 16.529 ft, the arc length of C is 2.065 ft, and the arc length of OD is 8.263 ft.

To shoot a 20-cm-long arrow parallel to the axle and through the wheel without hitting any spokes, the arrow should be aimed at a point on the circumference of the wheel that is 4 cm away from any spoke.

The diameter of the wheel is 60 cm (2 x radius), so the circumference is 188.5 cm (π x diameter). Since the arrow is 20 cm long, it must pass through the wheel at a point that is at least 20 cm away from any spoke. To find this point, divide the circumference of the wheel by the number of spokes (which is not given in the problem).

Since the spokes are equally spaced, this will give the minimum distance between any two spokes. For example, if there are 6 spokes, the distance between each spoke is 31.4 cm (188.5 / 6). Therefore, the arrow should be aimed at a point on the circumference of the wheel that is 4 cm (20 / 5) away from any spoke.
