Answer:

40%

Step-by-step explanation:

The probability of the arrow landing on the green section is a 40% chance

This is because there are only 3 sections where one is 50 and the other is 10

To find the green we can create an equation, where x = green section

50 + 10 + x = 100

The equation equals 100 because that's the highest the percentage will go in probability, unless we were told otherwise

60 + x = 100

x = 100 - 60

x = 40

Answer:

i. The relative error in the estimated distance is approximately 7.5%.

ii. The value of the estimated distance was about 12.5 miles far of from the actual value.

Step-by-step explanation:

Given that;

Estimated distance  ≅ 180 miles

Actual distance = 167.5 miles

Then,

Estimated distance - Actual distance = 180 - 167.5

                                                             = 12.5 miles

So that,

Relative error = [tex](\frac{estimated distance - actual distance}{actual distance} )[/tex] × 100%

                       = [tex]\frac{12.5}{167.5}[/tex] × 100%

                       = 0.07463 × 100%

                       = 7.5%

i. The relative error in the estimated distance is approximately 7.5%.

ii. The value of the estimated distance was about 12.5 miles far of from the actual value.

Answer:

L = 30 m

Step-by-step explanation:

lets make it simple and accurate

given

reel dia = 5 cm = 0.05 m

200 times round the reel

π = 3

reel O circumference = π d

Length of thread = Number of times round the reel x circumference

therefore,

L = 200 x (3 * 0.05)

L = 30 m

The approximate length of the thread wound around the reel is 30 meters.

Here, we have,

To find the approximate length of the thread wound around the reel, we can use the formula for the circumference of a circle.

Circumference = π * diameter

Given that

the diameter of the reel is 5 cm and we are using the value 3 for π, we can calculate the circumference:

Circumference = 3 * 5 cm

Circumference = 15 cm

Now, since the thread is wound 200 times around the reel, we need to calculate the total length of the thread:

Total length of thread = Circumference * Number of times wound

Total length of thread = 15 cm * 200

Total length of thread = 3000 cm

To convert the length from centimeters to meters, we divide by 100:

Total length of thread in meters = 3000 cm / 100

Total length of thread in meters = 30 meters

Therefore, the approximate length of the thread wound around the reel is 30 meters.

Answer:

Plane A / 7.62 mi away

Step-by-step explanation:

We have to calculate the distance of each plane from the airport.

In other to do this, we would use the trigonometric function of Sine

sin θ = Opposite/Hypotenuse

For Plane A

Plane A departs at a 41° angle from the runway

sin θ = Opposite/Hypotenuse

θ = 41°

Distance from the ground = Opposite = 5 miles

Hypotenuse = ???

sin 41° = 5 miles/Hypotenuse

sin 41° × Hypotenuse = 5 miles

Hypotenuse = 5 miles/sin 41°

Hypotenuse = 7.6212654335 miles

Approximately to the nearest hundredth ≈ 7.62 miles

For Plane B

Plane B departs at a 43° from the runway

sin θ = Opposite/Hypotenuse

θ = 43°

Distance from the ground = Opposite = 5 miles

Hypotenuse = ???

sin 43° = 5 miles/Hypotenuse

sin 43° × Hypotenuse = 5 miles

Hypotenuse = 5 miles/sin 43°

Hypotenuse = 7.3313959282 miles

Approximately to the nearest hundredth ≈ 7.33 miles

From the above calculation, we can see that Plane A what 7.62 miles away from the airport while Plane b was 7.33 miles away from the airport.

Therefore Plane A was farther away from the airport (7.62 miles away) when it was 5 miles from the ground.

Step-by-step explanation:

The given parameters are;

The amount Mark will make at annually as an engineer = $65,000

The percentage annual pay increase guaranteed by the company = 2%

The explicit function that represents Mark's salary can be presented as follows;

Let Mark's present salary = y

Therefore we have;

y = $65,000× (1 + 0.02)ˣ = $65,000× (1.02)ˣ

Factor analysis

Step-by-step explanation:

Factor Analysis is a method for modeling observed variables, and their covariance structure, in terms of a smaller number of underlying unobservable “factors.” These factors are typically viewed as broad concepts or ideas that may describe a noted occurrence.

Take for example:

A basic impulse of acquiring a certain social level might explain most consumption behavior. These unobserved factors are more interesting to the social scientist than the noted numerical measurements.

x = 23

Step-by-step explanation:

Step 1: Write out equation

(58 - x) - (x) = 12

Step 2: Distribute negative

58 - x - x = 12

Step 3: Combine like terms

58 - 2x = 12

Step 4: Subtract 58 on both sides

-2x = -46

Step 5: Isolate x (divide both sides by -2)

x = 23

1.  AB = 3x + 6 BC = 2x + 14 then, AC = 5x + 20

2. AB = 5x – 8 BC = 16 - 3x then, AC = 2x + 8

3. AC = 3x - 1 BC = 12-X then, AB = 4x - 13

4.  AB = 2x + 11 BC = 4x - 5 then AC = 6x + 6

5. AC = 6x-4 BC = 4x - 3 then AB = 2x - 1

What is Midpoint?

Midpoint is the point in the middle of the two endpoints of a line segment.

Now, B is midpoint of AC.

Then, AC = AB + BC

1. AB =  3x + 6, BC = 2x + 14

Then, AC = 3x + 6 + 2x + 14

         AC = 6x + 20

2. AB = 5x – 8,  BC = 16 - 3x

Then, AC = 5x - 8 + 16 - 3x

        AC = 2x + 8

3. AC = 3x - 1,  BC = 12-x

Then, AB =( 3x -1 ) - ( 12 - x )

        AB = 2x - 13

4.  AB = 2x + 11, BC = 4x - 5

Then, AC = 2x + 11 + 4x - 5

        AC = 6x + 6

5.  AC = 6x-4,  BC = 4x - 3

Then, AB = (6x - 4) - (  4x - 3 )

        AB = 2x - 1

[tex]\sqrt{61}[/tex] ≈ 7.81

Step-by-step explanation:

Calculate the distance d using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = P1(- 4, - 3) and (x₂, y₂ ) = P2(2, 2)

d = [tex]\sqrt{(2+4)^2+(2+3)^2}[/tex]

   = [tex]\sqrt{6^2+5^2}[/tex]

   = [tex]\sqrt{61}[/tex] ≈ 7.81 ( to 2 dec. places )

The distance between P₁ = (-4, -3) and P₂ = (2, 2) is 7.810

The distance between two points is the shortest length between two points.

Given P₁ = (-4, -3) and P₂ = (2, 2) are the two points

             is [tex]\sqrt({x_{2}-x_{1})^{2} )+({y_{2}-y_{1})^{2} }[/tex]

Answer:

1) The domain In interval notation is [0, 20]

2) The range in interval notation is [100, 700]

Step-by-step explanation:

The given parameters are;

The amount Beth saved per month = $30

The number of months Beth saved = 20 months

The amount with which Beth opened her account = $100

Therefore, the amount of money Beth saved with respect to time is given as follows;

Y = $100 + $30 × X

Where;

Y = The amount of money Beth saved

X = The time (number of months) Beth saved

The domain is given as follows;

[tex]\{X | \ 0 \leq X \leq 20 \}[/tex]

The domain in interval notation is [0, 20]

For the range, when X = 0, Y = $100

When X = 20, Y = $100 + $30 × 20 = $700

Therefore, the range is given as follows;

[tex]\{Y | \ 100 \leq Y \leq 700 \}[/tex]

Which the range in interval notation is [100, 700].
