Answer:

229.18 degrees

Step-by-step explanation:

The circumference of a circle with radius r is 2×pi×r.

So if it has a radius of 1 mile, then the circumference is 2×pi×1=2pi miles.

So if we travel 4 miles, then the percentage of this circle we traveled is 4/(2pi)=63.66% approximately.

There are 360 degrees in a circle and we want to how much of that rotation belongs to traveling 4 miles of the circumference of a circle that measures 2pi miles. So 63.66%×360 degrees =229.18 degrees.

The net force acting on a 14kg wagon that produces an acceleration of 1.5 m/s2 is 21N.

Force is an external agent that is capable of changing the state of rest or motion of a body. It has a magnitude and a direction. The direction towards which the force is applied is known as the direction of the force, and the application of force is the point where force is applied.

It is simply known as a push or a pull.

The Force can be measured using a spring balance. The SI unit of force is Newton(N).

Force = mass x acceleration

Force = m x a

where mass = 14kg

acceleration = 1.5m/s2

Force = 14 x 1.5

Force = 21N

Answer:  430000

Step-by-step explanation: you have to do pemdas

Answer: 430,000. /four hundred thirty thousand

Step-by-step explanation:

The value of 4.3 x 10^5 is 430,000.

To understand this, the notation 4.3 x 10^5 represents a number in scientific notation, where 4.3 is the coefficient or significand, and 10^5 is the exponent. The exponent of 10 tells us how many places to move the decimal point to the right. In this case, the exponent 5 means we need to move the decimal point five places to the right.

Starting with 4.3, we move the decimal point five places to the right to get 430,000. So, 4.3 x 10^5 is equivalent to 430,000.

In the C-Chart, the value of the C-bar, representing the average count of nonconformities per unit, does not have to be an integer. So, the statement 'In the C-Chart, the value of C-bar must be an integer' is false.

In the C-Chart (also known as the Count Chart), the value of C-bar does not necessarily have to be an integer.

C-bar represents the average count of nonconformities per unit. It can be a decimal value, especially when dealing with continuous data or when the sample size is large.

The C-Chart is a statistical process control chart used to monitor the count of nonconformities in a process. It helps to determine if the process is in control or if there are any unusual patterns or trends in the nonconformity counts. The C-bar value is typically calculated as the total number of nonconformities divided by the number of units or observations.

So, the value of the C-bar in the C-Chart can be a decimal or fractional value, not necessarily an integer.

The centroid of the octant of the solid sphere is located at the point (3r/8, 3r/8, 3r/8).

The centroid of a solid of constant density is defined as the point at which the entire mass of the object is considered to be concentrated.

For an octant of a solid sphere, we can imagine a sphere with radius r, and cut it into eight equal parts by three mutually perpendicular planes passing through the center of the sphere. An octant is one of these eight parts, consisting of one-eighth of the volume of the sphere.

Since the solid has constant density, we can assume that the mass is distributed evenly throughout the volume. The centroid of the octant will be located at the center of mass of this octant.

To find the coordinates of the centroid of the octant, we can use spherical coordinates. Let the radius of sphere be r, and let theta range from 0 to pi/2 and phi range from 0 to pi/2, so that we are considering only the octant in the positive x, y, and z directions.

The coordinates of the centroid will be (x_c, y_c, z_c), where

x_c = (3/(4pir^3)) * ∫∫∫ x dV

y_c = (3/(4pir^3)) * ∫∫∫ y dV

z_c = (3/(4pir^3)) * ∫∫∫ z dV

where the integrals are taken over the volume of the octant.

Using spherical coordinates, we can express x, y, and z in terms of r, theta, and phi, and we can express dV in terms of r, theta, and phi as well. After integrating over theta and phi, we get:

x_c = y_c = z_c = 3r/8

Therefore, the centroid is at the point (3r/8, 3r/8, 3r/8).

The required area of Fiona's circle is49π. Option D is correct.

The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by

(x - h)² + (y - k)² = r²

Where h, k is the coordinate of the center of the circle on a coordinate plane and r is the radius of the circle.

The radius of Fiona's circle is half of the diameter, which is 14/2 = 7 meters.

The formula for the area of a circle is A = πr², where A is the area and r is the radius.

Substituting the value of the radius in the formula, we get:

A = π(7)² = 49π

So, the area of Fiona's circle is 154 square meters, if we use the value of π as 3.14.

Therefore, the answer is 49.

The value of the particular antiderivative is F(x) = 4x + 48√x - 44.

Given:
f(x) = 4√√x + 6 and F(1) = 8.

The antiderivative of f(x) is given by integrating f(x) with respect to x.

That is,F(x) = ∫f(x)dxNow we will integrate f(x) using u substitution.

u = √x. Then, du/dx = 1/(2√x)dx.

=> dx = 2u√xdudx = 2u du

Substituting the above u substitution and solving for the antiderivative, we have,

F(x) = ∫4√√x + 6 dx=> ∫4(u + 6) * 2udu=> ∫8u + 48 du=> 4u² + 48u + C

Putting the value of u in terms of x back, we have,

F(x) = 4(√x)² + 48√x + C=> F(x) = 4x + 48√x + C

As F(1) = 8, we can find the value of C. That is,8 = 4(1) + 48(1) + C=> C = -44

Thus, the value of the particular antiderivative is F(x) = 4x + 48√x - 44.

Thus, the variance for the given set of data representing the population is found as : Variance =  16 (approx).

Variability is measured by the variance. The average of the squared deviations from the average is used to calculate it. That degree of spread in the data set is indicated by variance. The variance is greater in respect to the mean the more dispersed the data.

Mean U = 6

x           =    1       5    7      11

(X-U)²   =    25    1       1      25

Variance =  [(6 - 1)² + (6 - 5)² + (6 - 7)² + (6 - 11)² ]/ 4

Variance =  [25 + 1 + 1 + 25 ]/ 4

Variance = 62/ 4

Answer:

this is a math problem that involves using the Pythagorean theorem. The ladder, the roof and the ground form a right triangle, where the ladder is the hypotenuse and the roof and ground are the legs. The length of the ladder can be found by using this formula:

ladder^2 = roof^2 + ground^2

Plugging in the given values, we get:

ladder^2 = 3^2 + 2^2

ladder^2 = 9 + 4

ladder^2 = 13

To find the length of the ladder, we need to take the square root of both sides:

ladder = sqrt(13)

Using a calculator, we can approximate this value as:

ladder ≈ 3.6

Rounding to the nearest tenth, we get:

ladder ≈ 3.6 meters

Therefore, the ladder is about 3.6 meters long.

Step-by-step explanation:

A large sample size and low variability increase the likelihood of rejecting the null hypothesis, while a small sample size and high variability decrease the likelihood of rejecting the null hypothesis.

When a sample is selected from a population and a treatment is administered, it is important to determine if the treatment had a significant effect on the sample. This is done by comparing the sample mean to the original population mean and testing if the difference is statistically significant.

If there is a 3-point difference between the sample mean and the original population mean, the likelihood of rejecting the null hypothesis depends on the characteristics of the sample. In particular, the size of the sample and the variability of the data can influence the likelihood of rejecting the null hypothesis.

If the sample size is large and the data is relatively homogeneous (low variability), then even a small difference between the sample mean and the population mean may be statistically significant. This is because a larger sample size allows for more precision in estimating the population mean and reduces the effect of random sampling error.

On the other hand, if the sample size is small and the data is highly variable, a larger difference between the sample mean and the population mean may be required to reject the null hypothesis. This is because a small sample size and high variability increase the uncertainty in estimating the population mean and make it more difficult to detect small differences.

In summary, when there is a 3-point difference between the sample mean and the original population mean, the likelihood of rejecting the null hypothesis depends on the sample characteristics, specifically the size of the sample and the variability of the data.
