The value of x in the triangle is 21, option B is correct.

The given triangle is right triangle

We know that the sine function is the ratio of opposite side and hypotenuse

Opposite side =19

Hypotenuse =x

We have to find the value of x

Sin 65 = 19/x

0.91 =19/x

x=19/0.91

x=20.8

x=21

Hence, the value of x in the triangle is 21, option B is correct.

The area of the circle with a circumference of 6pi m is 9π square meters.

A circle is simply a closed 2-dimensional curved shape with no corners or edges.

The area of a circle is expressed mathematically as;

A = πr²

The circumference of a circle is expressed as:

C = 2πr

Where r is radius and π is constant pi.

We are given that the circumference of the circle is 6π m, so we can set up the equation and solve for the radius.

C = 2πr

6π = 2πr

Simplifying, we get:

r = 6π/2π

r = 3

Now that we know the radius of the circle, we can use the formula for the area of a circle:

A = πr²

Substituting the value of r, we get:

A = π(3)²

Simplifying, we get:

A = 9π

Therefore, the area is 9π m.

A one-tailed t-test is used when the researcher has a specific directional hypothesis.

If you are comparing the difference between two separate populations, such as children who attend two different Elementary schools, you should use an independent-measures design. In an independent-measures design, two separate groups of participants are sampled, and each participant is only tested once. The purpose of this design is to compare the means of two independent populations to determine if there is a statistically significant difference between them. In contrast, a within-groups design would involve testing the same group of participants twice under different conditions, while a repeated-measures design would involve testing the same group of participants under all conditions. A one-tailed t-test is a specific type of statistical test that can be used in either an independent-measures or within-groups design to test a directional hypothesis.

Answer:

mean = 52

Step-by-step explanation:

In mathematics, the mean is a measure of central tendency that represents the average of a set of numbers. It is also commonly known as the arithmetic mean.

To calculate the mean, you add up all the numbers in a set and then divide by the total number of values in the set.

So in tho case we would add all the values then divide by the amount of values there are.

1) rewrite values:

42  45  58  63

2) add:

42 + 45 + 58 + 63
= 208

3) divide:

Since there arev4 values we will divide by 4.

208 / 4 = 52

The required, equation to determine the number of people is T + (T + 5,500) + 2T + (2T + 300) = 36,700 and there were 10,300 people at the fair on Saturday.

Let's call the number of people who attended the fair on Thursday "T". Then we can use the information in the problem to set up an equation:

Friday's attendance = T + 5,500

Saturday's attendance = 2T

Sunday's attendance = 2T + 300

Total attendance = T + (T + 5,500) + 2T + (2T + 300) = 36,700

Simplifying the equation, we get:

6T + 5,800 = 36,700

6T = 30,900

T = 5,150

Therefore, the attendance on Thursday was 5,150 people. We can use this information to find the attendance on Saturday:

Saturday's attendance = 2T = 2(5,150) = 10,300

Thus, there were 10,300 people at the fair on Saturday.

To predict the number of situps a person who watches 13.5 hours of TV can do, we can use the given regression equation y = ax + b, where 'a' and 'b' are the coefficients and 'x' is the hours of TV watched.

Given:
a = -1.077
b = 30.98
x = 13.5

Step 1: Substitute the given values into the regression equation:
y = (-1.077)(13.5) + 30.98

Step 2: Perform the calculations:
y = (-14.5395) + 30.98

Step 3: Add the values:
y = 16.4405

The solution of the system of equations  -10x - 9y = 10 and 8x + 9y = 10 is x = 10 and y = -3.33

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

So, we have

-10x - 9y = 10

8x + 9y = 10

When the above equations are added to one another, we have

2x  = 20

This means that

x = 10

a) The light flashes as the circuit leaves the field at a speed of 16 ms.

b) The current flow as the loop exits the field in the clockwise direction.

c) The power dissipated in the bulb during the flash is 0.04 W. 

To reply to these questions, we will utilize Faraday's Law, which states that a changing attractive field actuates an electromotive drive (EMF) in a circuit, and the initiated EMF is rise to the rate of alter of attractive flux through the circuit.

a) The attractive flux through the circle is given by the item of the attractive field, region of the circle, and cosine of the point between the attractive field and the ordinary to the plane of the circle.

As the circle is pulled out of the attractive field, the magnetic flux through the circle diminishes, and thus, an EMF is actuated within the circle. This initiated EMF drives a current through the light bulb, causing it to light up.

The time term of the streak of light can be decided from the time taken by the circle to move out of the attractive field.

The removal voyage by the circle is 40 cm, and the speed is 25 m/s, so the time taken is:

t = d/v = 0.4 m / 25 m/s = 0.016 s = 16 ms

Subsequently, the streak of light endures for 16 ms.

b) Concurring to Lenz's Law, the course of the initiated current is such that it contradicts the alter within the attractive flux that produces it. As the circle is pulled out of the attractive field, the attractive flux through the circle diminishes.

Hence, the actuated current flows in a course that makes a magnetic field that restricts the initial attractive field. This could be accomplished by the induced current streaming clockwise as seen from above. Hence, the reply is clockwise.

c) The control scattered within the light bulb can be calculated utilizing the equation P = V²/R, where V is the voltage over the bulb and R is its resistance.

The voltage over the bulb is break even with to the initiated EMF, which can be calculated from Faraday's Law. The attractive flux through the circle changes at a rate of (40 cm) x (25 m/s) = 1 T.m²/s.

The region of the circle is (40 cm) x (10 cm) = 0.04 m². The cosine of the point between the attractive field and the ordinary plane of the circle is 1 (since the circle is opposite to the field). Subsequently, the induced EMF is:

EMF = -d(phi)/dt = -NA(dB/dt)

= -(1)(0.04 m²)(1 T.m²/s)/0.016 s

= -1 V

The negative sign indicates that the actuated EMF is within the inverse course of the current stream. Subsequently, the voltage over the light bulb is:

V = -EMF = 1 V

The power dissipated within the bulb is:

P = V²/R = (1 V)²/25 ohm = 0.04 W

Subsequently, the control scattered within the bulb during the streak is 0.04 W.

Yes, that is correct. The Gaussian elimination rules are essentially the same as the three basic row operations, which allow you to algebraically manipulate a matrix's rows.

You can interchange two rows, multiply a row by a constant, or add a row to another row. These rules are essential in solving systems of linear equations and finding the reduced row echelon form of a matrix. By applying these rules, you can transform a matrix into an equivalent matrix that is easier to work with and reveals important information about the system of equations or the matrix itself. The Gaussian elimination rules, also known as the three basic row operations, allow you to algebraically manipulate a matrix in order to solve systems of linear equations. These operations include:
1. Interchanging two rows (R2 ↔ R3)
2. Multiplying a row by a nonzero number (R1 → kR1, where k is a constant)
3. Adding a row to another row (R2 → R2 + 3R1)

We can conclude that if X is normally distributed with a mean of 11 and a standard deviation of 3, then the value of x that solves P(X > x) = 0.8 is x = 13.52.

We need to find the value of x such that P(X > x) = 0.8, where X is a normally distributed random variable with mean μ = 11 and standard deviation σ = 3.

From the properties of the standard normal distribution, we know that if Z is a standard normal random variable, then P(Z > z) = 0.8 corresponds to z = 0.84 (found using a standard normal table or calculator).

We can standardize X to a standard normal random variable Z using the formula:

Z = (X - μ) / σ

Substituting the values μ = 11 and σ = 3, we get:

Z = (X - 11) / 3

Now, we want to find the value of x such that P(X > x) = 0.8. We can rewrite this as:

P(Z > (x - 11) / 3) = 0.8

Using the standard normal table or calculator, we find that P(Z > 0.84) = 0.2005.

Therefore, we can write:

0.2005 = P(Z > 0.84) = P((X - 11) / 3 > 0.84) = P(X > 11 + 3(0.84)) = P(X > 13.52)

So the value of x that solves P(X > x) = 0.8 is x = 13.52.

t = (71 - 73) / (1.5 / sqrt(40)) = -4.38
