Answer:

The equation of the circle is (x-2)^2+(y-1)^2=13

Step-by-step explanation:

The average of first 50 numbers is 25.5 because average is computed by adding a set of numbers and then dividing by the total number of those numbers.

The average of a list of data is a mathematical expression for the central value of a set of data. The ratio of all the data points to all the units in the list is how it is mathematically defined. The average of a specific set of numerical data is also referred to as the "mean" in statistics.

The four sorts of average that we recognize are mean, mode, median, and range. Although the others are our most popular "measures of central tendency," range is actually a measure of spread or distribution.

The first 50 natural numbers are 1,2,3,...,50

The sum of first n natural numbers = n(n+1)/2

Sum of first 50 natural numbers is  50(51)/2

=25(51)/2=1275

Hence, average of first 50 natural numbers is  

1275/50

=25.5

The equation of the line (-4,3) and (2,-4) is y = -7/6x -5/3.

What is equation of line?

The equation of a line is the algebraic representation of a line using cartesian coordinates. The general form of the equation of a straight line is written as y = mx + c. Where m is the gradient of the straight line and c  is the y y-intercept of the straight line.

Given, the points are (-4,3) and (2,-4)

m = -4-3/2+4

m = -7/6

The equation we get

y = -7/6x +b

the point (-4,3), we get

3 = -7/6(-4) +b

3 = 14/3 +b

3-14/3 = b

b = -5/3

Hence, the equation of line is y = -7/6x -5/3.

Answer: 8%

Step-by-step explanation: Rate = Interest 484 ÷ Principle (550) x Time (11), with this formula the answer is 8%.

When x = -0.5, the value of y is -0.33. When y varies directly with respect to x, the equation y = kx is used. where k is the constant of proportionality

Therefore,

When X equals 3, Y equals 2.

We solve for k by plugging in 3 for x and 2 for y.

y = kx \s 2 = k(3) (3)

Subtract 3 from both sides.

2/3 = k

Now we plug in 2/3 for k

y = 2/3 x

Given x = -0.5  simplifying we get,

y = 2/3 (-0.5)

y = -0.33

Hence, the value of y is -0.33 when x = -0.5

1.2113 ft/s is the speed at which the radius of the sphere is changing when the radius is 6 feet .

Mensuration is a division of mathematics that studies geometric figure calculation and its parameters such as area, length, volume, lateral surface area, surface area, etc. It outlines the principles of calculation and discusses all the essential equations and properties of various geometric shapes and figures.

Mensuration is a subject of geometry. Mensuration deals with the size, region, and density of different forms both 2D and 3D. Now, in the introduction to Mensuration, let’s think about 2D and 3D forms and the distinction between them.

The rate of change of volume will be the product of the rate of change of radius and the area of the sphere. The area of the sphere is ...

 A = 4πr² = 4π(6 ft)² = 144π ft²

Then the relationship above is ...

dV/dt = A·dr/dt

548 ft³/s = (144π ft²)·dr/dt

dr/dt = (548 ft³/s)/(144π ft²) = 137/(36π) ft/s ≈ 1.2113 ft/s

If a decision maker wishes to reduce the margin of error associated with a confidence interval estimate for a population mean, she can increase the sample size.

The margin of error refers to the statistic measurement that expresses the level of random sampling error in the outcomes of a survey. If the margin of error of the result is high, the confidence level would be low that a result reflects the census of the entire population. It indicated the difference between the actual and estimated results in a random survey sample. The margin of error is generally used in non-survey contexts to show observational error in reporting measured quantities. In order to minimize the margin of error associated with a confidence interval estimate for a population mean, the researchers can increase the sample size to capture the actual trend of the population more accurately.

What is standard deviation?

It is a measure of how spread out numbers are. It is the square root of the Variance, and the Variance is the average of the squared differences from the Mean.

Main Body:

Here, we want to use the empirical rule to find the percentage of women with shoe sizes less than 11.19

The first thing we shall do here is to find the z-score

Mathematically, that will be calculated using the formula;

z = (x-mean)/SD

z = (11.19-8.21)/1.49

z = 2

We can see that the given value is 2 standard deviation away to the right of mean

So, we want to get the percentage that is between the mean and two standard deviations away from it using the empirical rule

Step-by-step explanation:

The measure of angle B is 40 degrees.

In this question, we have been given angle A and angle B are supplementary angles.

m∠A=(4x−16)°

and m∠B=(x+1)°

since angle A and angle B are supplementary angles,

angle A + angle B = 180°

So we get an equation,

(4x − 16)° + (x + 1)° = 180°

5x - 16 + 1 = 180

5x = 180 + 15

5x = 195

Using the z table, the probability that a standard normal random variable will be between 0.3 and 3.2 is 0.3814.

In the given question,

We have to find that the probability that a standard normal random variable will be between 0.3 and 3.2 .

We firstly learn about a standard normal random variable which is expressed with a mean and standard deviation.

Since we have to find the probability that a standard normal random variable will be between 0.3 and 3.2 .

So The probability should be

P(0.3<z<3.2)=P(z<3.2)−P(z<0.3)

From the standard value of z

P(0.3<z<3.2)=0.9993−0.6179

Simplifying

P(0.3<z<3.2)=0.3814

Hence, the probability that a standard normal random variable will be between 0.3 and 3.2 is 0.3814.

As per the question statement, we are provided with a set of values       [1/3, 0.3, 33%, 8/25, 33.6%],

And we are required to rearrange the above mentioned set in the ascending order of magnitude.

To answer this question, we will have to convert all the values into fractions with a common denominator, and then arrange the fractions in an ascending order of magnitude of their numerators to obtain our desired answer, that is,

[(1/3) = 0.33333333...]

[(0.3) = (3/10) = (30/100)],

[(33%) = (33/100) = 0.330],

[(8/25) = (32/100) = 0.320]

And, [33.6% = (33.6/100) = 0.336]

Since (0.336 > 0.333 > 0.330 > 0.320 > 0.300),

Therefore, rearranging [1/3, 0.3, 33%, 8/25, 33.6%] in the ascending order of magnitude, we get, [33.6%, (1/3), 33%, (8/25), 0.3]
