The average of the four random variables has a standard deviation of 0.969.

A random variable provides a rule that gives each result in a sample space a numerical value.

You must do the subsequent actions in order to determine the standard deviation for random variables:

Consider a case:

The likelihood of choosing a swimmer at random from each of the four stroke categories—1, 2, 3, and 4—is 0.2, 0.3, 0.5, and 0.1, respectively. Discover the total standard deviation of the four random variables.

This could be solved as;

First, we must determine the average value for each category.

In this case, the expected value serves as the mean.

We must multiply every value by its likelihood before summing the results to determine the expected value.

μ = E(x) = ∑xp(x)

Thus, (0.2x1) + (0.3x2) + (0.5x3) + (0.1x4) = 0.2 + 0.6 + 1.5 + 0.4 = 2.7

Mean = 2.7

The initial and second steps are now being taken.

(1 - 2.7)² x 0.2 = 2.89 x 0.2 = 0.578

(2 - 2.7)² x 0.3 = 0.49 x 0.3 = 0.147

(3 - 2.7)² x 0.5 = 0.09 x 0.5 = 0.045

(4 - 2.7)² x 0.1 = 1.69 x 0.1 = 0.169

The final stage is when we combine our products to acquire the variance V.

V = σ2 = ∑(x−μ)2P(x)

V = 0.578 + 0.147 + 0.045 + 0.169 = 0.939

The final step is to calculate the standard deviation (SD) by taking the variance's square root.

SD = σ = √σ2

Standard Deviation SD = √0.939

Standard Deviation SD = 0.969

Thus, the average of the four random variables has a standard deviation of 0.969.

The number of each type of coin in the jar is 76 quarters and 83 dimes.

Given data :

Thomas collects dimes and quarters in his change jar.

If he has 7 more dimes than quarters, and the total amount of money in the jar is $27.30.

Let, x be the number of the dimes.

And y be the number of quarters.

If he has 7 more dimes than quarters,

y = x + 7

The total amount of money in the jar is $27.30.

0.25x + 0.10y = 27.30

Substitute the value of y in equation 2

0.25x + 0.10(x + 7) = 27.30

0.25x + 0.10x + 0.7 = 27.30

0.35x = 27.30 - 0.7

0.35x = 26.6

x = 26.6 / 0.35 = 76

Substitute the value of x in equation 1

y = x + 7

y = 76 + 7 = 83

Hence, there are 76 quarters and 83 dimes in the jar.

Applying the midpoint formula, the endpoints for the midsegment are (-0.5, 0.5) and (-5/2, -7/2).

The midsegment of a trapezoid is the line segment that intersects the two legs of the trapezoid at their midpoints.

Hence, to find the endpoint for the midsegment of the other leg of the trapezoid, apply the midpoint formula, M[(x2 + x1)/2, (y2 + y1)/2].

Find the midpoint between A(-2, -5) and B(-3, -2):

A(-2, -5) = (x1, y1)

B(-3, -2) = (x2, y2)

Plug in the values

M[(-3 + (-2))/2, (-2 + (-5))/2]

M(-5/2, -7/2)

Therefore, using the midpoint formula, the endpoints for the midsegment are (-0.5, 0.5) and (-5/2, -7/2).

Step-by-step explanation:

The mutual inductance of the two coils come out to be 1.1 x 10⁻³ H.

When two wire coils are brought near enough together that the magnetic field through one links with the magnetic field on the other, the voltage is formed in the second coil. When a voltage is applied to one coil, it induces a voltage in the other. This is known as mutual inductance.

Now, for the given values of;

Rate of current in coil 1 is  5.6 a/s.

The emf is  6.0 x 10⁻³ V

According to the mutual inductance of a coil, the flux coupled to coil 2 goes proportional to the current flowing in coil 1.

As a result, we will have

\(\phi_{2}=M i_{1}\)

We know from this that the rate of change of flux is equivalent to the EMF created in the coil.

As a result, we will have

\(\frac{d \phi_{2}}{d t}=M \frac{d i_{1}}{d t}\)

This equation in terms of emf is;

\(E M F=M \frac{d i}{d t}\)

Substituting the values in the above equation;

6.0 x 10⁻³ = M×5.6

M =  1.1 x 10⁻³ H.

Therefore, the mutual inductance of the two coils is  1.1 x 10⁻³ H.

Answer: Let's say the width of the rectangle is "w" meters.

According to the problem, the length of the rectangle is 2 meters greater than twice its width. Therefore, the length of the rectangle can be expressed as: 2w + 2.

The area of a rectangle is given by multiplying its length and width. We are given that the area of the rectangle is 40 m². Therefore, we can write:

w(2w + 2) = 40

Expanding the left side of the equation, we get:

2w² + 2w = 40

Bringing all the terms to one side, we get a quadratic equation:

2w² + 2w - 40 = 0

Dividing both sides by 2, we get:

w² + w - 20 = 0

This equation can be factored as:

(w + 5)(w - 4) = 0

Therefore, the solutions to this equation are w = -5 and w = 4. Since the width of a rectangle cannot be negative, we reject the solution w = -5. Thus, the width of the rectangle is 4 meters.

Using the expression for the length in terms of the width, we can find the length of the rectangle:

length = 2w + 2 = 2(4) + 2 = 10

Therefore, the length of the rectangle is 10 meters.

Step-by-step explanation:

Answer:

10 meters

Step-by-step explanation:

Set up equations to represent the problem.

Let L represent the length of the rectangle.
Let W represent the width of the rectangle.

LW = 40 m²

L = 2W + 2

Use substitution to solve the system.

(2W + 2)(W) = 40

(2)(W + 1)(W) = 40

(W + 1)(W) = 20

W² + W = 20

W² + W - 20 = 0

(W + 5)(W - 4) = 0

Solutions of W are -5 and 4; -5 doesn't make sense because the width can't be (-5 meters). The width of the rectangle is 4 meters. Substitute this into our equation for length.

L = 2W + 2

L = 2(4) + 2

L = 10 meters

The two cars are 10.5 kilometers apart, measured in a straight line.

This is calculated by taking the square root of the sum of the squares of the distances traveled by the two cars (3.1 km and 8.3 km). The square root of (3.1² + 8.3²) is 10.47, which can be rounded up to 10.5.

To calculate the distance between the two cars, we first need to calculate the sum of the squares of the distances traveled by the two cars (3.1 km and 8.3 km).

3.1² + 8.3² = 68.49

Next, we take the square root of this sum to get the distance between the two cars in a straight line:

√68.49 = 8.25

Finally, we round this number up to the nearest tenth, giving us the final answer of 10.5 kilometers.

The coterminal angle for the -4π/5  are -14π/5 , 6π/5 and reference angle is π/5 respectively.

Two different angles that have the identical starting and ending edges termed coterminal angles however, since one angle measured clockwise and the other determined counterclockwise, the angles' terminal sides have completed distinct entire rotations.

We have an angle:

-4π/5

To find the coterminal angle, add and subtract by 2π in the angle -4π/5

Coterminal angle:

= -4π/5 - 2π

= -14π/5

= -4π/5 + 2π

= 6π/5

Reference angle:

= π - 4π/5  (as the angle lies in the second quadrant)
