Answer: 1264 pounds of garbage in one week

Step-by-step explanation: This problem is a unit rate problem, so, we need to find the unit rate of this word problem. To do that, you would do the amount of garbage produced (189.6) divided by the number of adults (6), which equals 31.6. So, the unit rate is 31.6 pounds of garbage for one adult. Then, you need to do 31.6 times 40 (for the number of adults) which equals 1264.

The value of the function instance h (-3) as required to be determined given the function declaration; h(x) = −3x + 15 is; 24.

It follows from the task content that the value of the function instance h (-3) is to be determined given the function h (x) = -3x + 15.

Since the given function is; h (x) = -3x + 15.

The value of the function instance; h (-3) can be determined by evaluating as follows;

h (-3) = -3 (-3) + 15

h (-3) = 9 + 15

h (-3) = 24.

On this note, the value of the function instance h (-3) as required is; 24.

Answer: y=2(x+1)^2 +7

Step-by-step explanation:

The equation for a parabola is y=a(x-h)^2+k

(h,k) would be the vertex but when writing the equation, the sign in front of the h has to be the opposite of the x-value in the vertex (note: the minus sign in front of the h just means opposite of, not always negative) So in this situation since the 1 is negative, it would be positive in the equation

The a represents the distance from the vertex to the focus.

In order to solve this problem you just sub in the opposite of h and the normal value of k and then the a would be two since that is the distance between the focus and the vertex.

This would make your answer 2(x+1)^2 +7

The best reason to prefer the least-squares regression line that uses to predict is the Standard Deviation of the residuals is smaller.

Least Squares Regression:

Least squares is a mathematical technique that allows analysts to determine the best way to fit a curve to a graph of data points. It is commonly used to make scatterplots easier to interpret and is associated with regression analysis. Least squares is now available as part of most statistical software programs.

There are two least-squares regression lines, one to predict log(y) using x and the other to use for prediction.

a. A small value of means that the variance is explained poorly compared to the model that predicts instead, and thus the model is a poorer model. Therefore, there is no compelling reason to choose a model that predicts logic in.

b. If the standard deviation of the residuals is not too high, there will be less variability between the actual and predicted values, and thus the model will be more accurate. Therefore, there are compelling reasons to favor a model that predicts.

C. The magnitude of the slope has no effect on whether a model is good or bad, so it's not the best reason to favor a model that expects log y and  x.

d. The presence of more random variation in the number of residuals does not necessarily indicate a superior model. The reason for this is that the variation between the expected and actual values ​​is large, which can lead to large variability. This means that there is no compelling reason to prefer a model that uses to predict log y. It is normal that the distribution of residuals of residuals does not affect model quality. As a result, this is not the best reason.

Answer: y = -1/2x + 4.

The equation of line passes through the points (0, 4) and (8, 0) will be;

⇒ y = -1/2x + 4

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Two points on the line are (0, 4) and (8, 0).

Now,

Since, The equation of line passes through the points (0, 4) and (8, 0)

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (0 - 4) / (8 - 0)

m = - 4 / 8

m = -1/2

We know that, The slopes of parallel lines are equal.

Thus, The equation of line with slope -1/2 is,

⇒ y - 4 = -1/2 (x - 0)

⇒ y - 4 = -1/2x

⇒ y = -1/2x + 4

Therefore, The equation of line passes through the points (0, 4) and

According to the question,

After t hours of production, a plant produces an average of y units per hour, according to analysis of its daily output is

y = 102t + 0.5t² - t³ , 0 ≤ t ≤ 10

The factor that produces the corresponding dimensions of cylinder B is: 3/2.

Similar solids have the same shape but different sizes, and which means the ratio of their corresponding linear measurements are the same.

To find the scale factor of similar solids, you can use the formula:

scale factor = (size of the similar solid) / (size of the original solid)

For example, if you have two similar solids, one with a volume of 64 cubic units and the other with a volume of 16 cubic units, the scale factor would be:

scale factor = (16 cubic units) / (64 cubic units) = 1/4

This means that the smaller solid is 1/4 the size of the larger solid.

Given the following:

Circumference of the base of cylinder A = 4π units [the radius = 2 units]

The perimeter of the rectangle is, 3y + 1 feet.

What is perimeter?

The circumference of a shape is known as its perimeter. The lengths of all four sides must be added in order to determine a rectangle's or square's perimeter. In this instance, the rectangle's length is represented by x and its width by y.

P = x + x + y + y represents the perimeter, P.

Let the length of triangle is 7.5y + 8 feet and the width of triangle is 6y - 7.5 feet.

So, the perimeter of rectangle is,

Perimeter = 2(length + width)

                = 2(7.5y + 8 + 6y - 7.5)

                 = 2(1.5y + 0.5)

Perimeter = 3y + 1

The total cost of painting and carpeting the 4 walls and the floor is C = ₹(720x² + 1324.8x).

Given is that a room three times as long as it is broad and its height is 4.6 m. The cost of carpeting its floor at Rs. 240 per square meter be  the cost of painting the 4 walls at Rs. 24 per sq. m.​

Assume that the breadth to be equivalent to [x] meters. Then its length will be [3x] meters.

Area of floor = {3x} x {x} = 3x² sq. m.​

The cost of carpeting the floor = Rs. 240 per sq. m.

For 1 sq. m., the cost is 240 sq. m.

For {3x² sq. m}, the cost will be -

C{f} = 240 x 3x² = 720x²

C{f} = 720x²

The total area of the 4 walls = 4 × (3x) × 4.6 = 55.2x sq. m.

The cost of carpeting the walls = Rs. 24 per sq. m.

For {55.2x sq. m}, the cost will be -

C{w} = 24 x 55.2x = 1324.8x

C{w} = 1324.8x

The total cost of painting and carpeting -

C = C{w} + C{f} = 720x² + 1324.8x

C = ₹(720x² + 1324.8x)

Let C(n) = min(αn, βn) then gcd(0,b) = p(1)^(c1)∙p(2)^(c2)..................p(n)^(cn).

So for all other a, b have gcd exist.

The value of the function after evaluation is , f(x)=0 . Hence it is neither a minima nor a maxima.

f(x) =(x + 5)^4; x = - 5

=(-5+5)^4

=(0)^4

=0

The critical value is crucial for accurately portraying a range of properties in statistics. The critical value can be helpful for proving or disproving ideas when they are tested, in addition to validity and accuracy.

If you're taking a statistics course or are just interested in how these concepts work, it is essential to comprehend critical value and how to compute it before analyzing other statistical functions, such as margin of error and significance.

When calculating the margin of error for a set of data, statisticians utilize a measurement known as the critical value.

Hi, To convert a temperature from degrees Fahrenheit to degrees Celsius, you can use the following formula:

C = (F - 32) / 1.8

Substituting the value of F and solving for C, we find that:

C = (284 - 32) / 1.8

= 252 / 1.8

= 140

Therefore, 284 °F is equivalent to 140 °C.

Using ratios we know that the total number of sweet Debs and Jamie has is 50.

A ratio in mathematics demonstrates how many times one number is present in another.

For instance, if a dish of the fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six.

Two quantities are compared to form a ratio.

An equality of two ratios is a proportion.

How to format a ratio Analyze the ratio to see whether it is part to part or part to whole.

Calculate the whole and the pieces as necessary.

So, we have a ratio of 3:7.

Debs has 20 fewer sweets than Jamie.

Let, Jamie have x sweets and Debs has x - 20.

Now, we get the equation:

3/x - 20 = 7/x

Now, solve as follows:

3/x - 20 = 7/x

3x = 7(x - 20)

3x - 7x - 140

7x - 3x = 140

4x = 140

x = 140/4

x = 35

x - 20 = 35 - 20 = 15

Total: 35 + 15 = 50

Therefore, using ratios we know that the total number of sweet Debs and Jamie has is 50.
