Hello !

James is performing statistical analysis to determine whether the effects of the treatment in his experiment might actually have reflected a chance occurrence; Kendra is performing an analysis to combine the results of a number of experiments to yield an overall conclusion. James is performing a significance test, Kendra, a meta-analysis.

The array that represents the total number of miles is X = 12

Given that;

Selena ran 4 miles per day

And she ran for 3 different days

Let the total miles she ran = X

therefore

X =  miles of 1st day  + miles of 2nd day  + miles of 3rd day

⇒ X = 4 + 4 + 4

⇒ X = 12 miles

Thus the symbolic form of miles Selena ran is,

X = 12.

Answer: To calculate the mean weekly earnings for each occupation in 2010, we need to add up the weekly earnings for each occupation and divide by the number of occupations.

For Forestry, logging and support:

Mean weekly earnings = (971) / (1) = $971

For Manufacturing:

Mean weekly earnings = (977) / (1) = $977

For Transportation and warehousing:

Mean weekly earnings = (900) / (1) = $900

For Construction:

Mean weekly earnings = (1071) / (1) = $1071

For Retail trade:

Mean weekly earnings = (501) / (1) = $501

Therefore, the mean weekly earnings for workers in the listed occupations in 2010 are:

Forestry, logging and support: $971

Manufacturing: $977

Transportation and warehousing: $900

Construction: $1071

Retail trade: $501

Step-by-step explanation:

An equation of the linear function represented by the graph in slope-intercept form is y = 3x + 60.

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical expression:

y - y₁ = m(x - x₁)

Where:

First of all, we would determine the slope of this line;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (75 - 60)/(5 - 0)

Slope (m) = 15/5

Slope (m) = 3

At data point (0, 60) and a slope of 3, a linear equation for this line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y - 60 = 3(x - 0)  

y = 3x + 60

The LCD of the rational equation above is 4(x + 7)(x - 7).

To find the LCD (Least Common Denominator) of the given rational equation, we need to factor the denominators of each fraction and then take the product of the highest powers of each factor.

The first denominator, x^2 - 49, can be factored using the difference of squares formula:

x^2 - 49 = (x + 7)(x - 7)

The second denominator, 4x + 28, can be factored by factoring out the greatest common factor:

4x + 28 = 4(x + 7)

Therefore, the LCD is the product of the highest powers of each factor, which is:

LCD = 4(x + 7)(x - 7)

So we need to multiply each term in the equation by an appropriate form of 1 so that the denominators of all the fractions become the LCD, 4(x + 7)(x - 7).

Answer:

When you divide 781.253 by 100, you get 7.81253 as the result.

The digit 2 is in the hundredths place in the dividend 781.253. Since we are dividing by 100, which has two decimal places, we move the decimal point two places to the left in the dividend to get the quotient.

Therefore, the digit 2 is in the ten-thousandths place in the quotient 7.81253.

The inequality represent the given graph is y≤1.4x+2.5.

From the graph, the line passes through (0, 2.5) and (3.5, 0).

Here, slope (m) = (3.5-0)/(2.5-0)

= 3.5/2.5

= 1.4

Substitute m=1.4 and (x, y)=(0, 2.5) in y=mx+c, we get

2.5=1.4(0)+c

c=2.5

So, the equation of a line is y=1.4x+2.5

So, the inequality is y≤1.4x+2.5

Therefore, the inequality represent the given graph is y≤1.4x+2.5.

Step-by-step explanation:

Lets say x and y are our numbers. x is the smaller number, y is the larger.

We can construct the equations:

x = 0.5y

x + y = 63

Substitute 0.5y for x in the second equation.

0.5y + y = 63

1.5y = 63

y = 42.

Plug y into the first equation.

x = 0.5 * 42

A statistical question is a question that can be answered by collecting and analyzing data. It is a question that expects a variability in the response, meaning different individuals may give different answers. Statistical questions usually ask about a population, a group of individuals or objects that share a common characteristic or feature, and seek to understand a pattern or trend within that population.

In general, a statistical question is open-ended, does not have a single correct answer, and requires data analysis to arrive at a reasonable conclusion.

To find out how many total miles Mario swam in the first week of training, we need to add up the distances he swam each time:

3/5 + 3/5 + 3/5 + 9/10 + 9/10 + 23/25 + 23/25

To add these fractions, we need to find a common denominator. The smallest common multiple of 5, 10, and 25 is 50.

3/5 = 30/50

9/10 = 45/50

23/25 = 46/50

Now we can add the fractions:

30/50 + 30/50 + 30/50 + 45/50 + 45/50 + 46/50 + 46/50

= (30 + 30 + 30 + 45 + 45 + 46 + 46)/50

= 272/50

= 5.44

Therefore, Mario swam a total of 5.44 miles in the first week of training.

Step-by-step explanation:

The vector v can be expressed as v = -0.161 i + 0.618 j, where i and j are the unit vectors

To express a vector v in terms of i and j, we need to find its x and y components. The magnitude ||v|| of a vector is given by:

||v|| = √(v₁² + v₂²)

where v₁ and v₂ are the x and y components of v, respectively.

The direction angle θ of a vector with respect to the positive x-axis is given by:

θ = atan(v₂/v₁)

where atan denotes the arctangent function.

In this problem, we are given that the magnitude ||v|| of the vector v is 2/3, and its direction angle θ with respect to the positive x-axis is 116 degrees. Therefore, we can write:

||v|| = √(v₁² + v₂²) = 2/3

θ = atan(v₂/v₁) = 116°

Solving for the x and y components, we get:

v₁ = ||v|| cos(θ) = (2/3) cos(116°) ≈ -0.161

v₂ = ||v|| sin(θ) = (2/3) sin(116°) ≈ 0.618

Therefore, the vector v can be expressed as:

v = -0.161 i + 0.618 j

where i and j are the unit vectors in the x and y directions, respectively.

The equation of the line that is parallel to the line that passes through the point (7, 6) is y = 8x - 50.

A line is an object in geometry that is indefinitely long and has neither breadth nor depth nor curvature.

Since lines can exist embedded in two, three, or higher dimensions environments, they are one-dimensional objects.

The term "line" can also be used to describe a line segment in daily life that contains two locations that serve as its ends.

So, the lines with the same slope but a different y-intercept are said to be parallel.

Therefore, we must use the same slope to plug in the point (7, 6) and solve for the y-intercept.

We thus have:

y = 8x + b

6 = 8(7) + b

6 = 56 + b

b + 56 = 6

b + 56 - 56 = 6 - 56

b = -50

The equation is: y = 8x - 50

Therefore, the equation of the line that is parallel to the line that passes through the point (7, 6) is y = 8x - 50.

Tthe reserve rate was approximately 0.9434, or 94.34%.

This is a geometric series with first term 3000r and common ratio (1-r), so we can use the formula for the sum of a geometric series:

sum = a(1 - r^n) / (1 - r)

where a = 3000r is the first term.

As the cycle continues indefinitely, the amount loaned out eventually becomes the final amount of $50,000. Therefore:

3000r/(1-r) = 50,000

Solving for r, we get:

r = (50,000)/(3000 + 50,000) = 0.9434

where a1 is the first term, r is the common ratio, and n is the term number.

Given the recursive rule for this geometric sequence as a1=4/9 and an=3an-1, we can find the common ratio:

an = 3an-1

an/an-1 = 3/1

r = 3

Now we can use the formula to find the explicit rule:
