Answer:

w = 6 / 21.

Step-by-step explanation:

To solve this equation, we first need to get all of the terms with the variable w on one side of the equation and all of the constants on the other side. To do this, we can use the distributive property to combine like terms on each side of the equation.

We can use the distributive property to combine the two terms on the left side of the equation to get 5 + 16w = 21w. This gives us the equation 21w = 6 - 45.

Next, we can add 45 to both sides of the equation to get 21w + 45 = 6 + 45. This simplifies to 21w + 45 = 51.

Finally, we can divide both sides of the equation by 21 to get the value of w. This gives us the equation w = (51 - 45) / 21 = 6 / 21.

Therefore, the solution to the equation is w = 6 / 21.

The equation of line that passes through points (-4, -5) and (-5, -7) is 2x - y + 3 = 0.

A line's equation is an algebraic way of expressing the collection of points that make up a line in a coordinate system.

The many points that collectively make up a line on the coordinate axis are represented as a group of variables (x, y) to create an algebraic equation, also known as an equation of a line.

The formula for equation of line that passes through points (x₁, y₁) and having slope m is, y - y₁ = m (x - x₁)

The given points are (-4, -5) and (-5, -7)

To find the equation of line, use formula,

y - y₁ = m (x - x₁)

Where m = (y₂ - y₁) / (x₂ - x₁)

For the points (-4, -5) and (-5, -7),

The slope m = (-7 - (-5)) / (-5 - (-4)) = (-7 + 5) / (-5 + 4) = -2 / -1 = 2

The required equation of line,

y - (-5) = 2 (x - (-4))

y + 5 = 2 (x + 4)

y + 5 = 2x + 8

2x - y + 3 = 0

The required equation of line is 2x - y + 3 = 0.

Split infinitives are grammatical structures where the words "to" and "infinitive" are separated. Move the phrase separating the infinitive from the split position to get rid of the split infinitive.

In the given question we have to explain, what is a split infinitive and how we fix it.

As we know that,

Split infinitives are grammatical structures in which an adverb or adverbial phrase separates the "to" and "infinitive" halves of what is more often known as the to-infinitive in modern linguistics.

A split infinitive is created when the word "to" and the infinitive verb are separated by an adverb. To eliminate the split infinitive, move the phrase that divides it from the split place.

The 0.75 represents the cost of the custom of each t-shirt and 9.99 represents the cost of custom shipment. And the total cost of 12 t-shirts is $18.99.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The cost (in dollars) of a uniquely crafted shirt is addressed as 0.75n + 9.99, where n is the number of words in the plan.

The cost of 12 t-shirts will be given as,

⇒ 0.75n + 9.99

⇒ 0.75 x 12 + 9.99

⇒ 9 + 9.99

⇒ 18.99

Answer:

The initial value in the given table is 41. This is the total cost to rent a costume for 1 day, which is the smallest number of days listed in the table. The initial value represents the fixed refundable security deposit that the costume rental store charges, which is a constant amount that does not depend on the number of days the costume is rented for.

Step-by-step explanation:

The smallest integers k and m that satisfy this are k=1450 and m=975, so N = 1131.

How to solve word problems?

It's actually fairly easy to solve word problems using a tried-and-true step-by-step approach.

If N is 22 percent less than one integer k, then

N = 78/100 k

= 38k/100

In N is 16 percent greater than another integer m, So

N = 116m / 100

= 29m/25.

Therefore, k is divisible by 50 and m is divisible by 25.

Setting these two equal, we have 38k/100 = 29m/25.Multiplying by $50$ on both sides, we get 39k = 58m

Hence, The smallest integers k and m that satisfy this are k=1450 and m=975, so N = 1131.

The same attribute is expressed using a unit conversion, but in a different unit of measurement. For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometers, feet, or any other measurement unit instead of miles.

The unitary approach involves calculating the value of a single unit, from which we can calculate the values of the necessary number of units.

mass of book=0.65 kg = 650g

The regression model is assumption of ols assumes that there is no correlation between the error and the independent variables

What is the Assumption of Linearity?

Linearity Assumption (OLS Assumption 1) - The model will be inaccurate and therefore unreliable if it is fitted to data that is not linearly connected. Extrapolating from the model is likely to produce inaccurate results. As a result, you must always draw a graph of the observed and anticipated values. The linearity assumption is confirmed if the graph is symmetrically distributed over the 45-degree line. By applying non-linear transformations to the independent variables, you can change the functional form of the regression if the linearity requirements are violated.

The OLS assumption of no multi-collinearity says that there should be no linear relationship between the independent variables.

Hence, The regression model is the assumption of ols assumes that there is no correlation between the error and the independent variables.

To paint 111 square meters of walls, it takes 6.05 hours. The result is obtained by using the speed of Natsumi to paint per hour.

With a constant speed to paint the wall, Natsumi has done painting as the shown data in the table.

Area (square meters) - Time (hours)

This is a problem with comparison. Let's take two samples of the data!

From the data, we know that for every additional 15 square meters, the time needed increases by 0.75 hours.

Then, we can continue the table.

The speed of Natsumi to paint per hour is

15/0.75 = 20 square meters/hour

The remain area

111 - 105 = 6 square meters

Time needed for the remain area is

6/20 = 0.3 hours

To paint 111 square meters of walls, it takes

x = 5.75 hours + 0.3 hours

Total degree of freedom should be known to determine the critical values for an independent sample t test.

The largest number of logically independent values—that is, values with the freedom to change—in the data sample is referred to as the degree of freedom. When calculating degrees of freedom, one is subtracted from the number of items in the data sample.

An independent t-test must be performed, and the following is required: a single categorical variable with two levels and groups that is independent. a single ongoing dependent variable.

For instance, the number of degrees of freedom to be employed in computations would be n - 1 if the sample size on a chi-square test was 'n'. to figure out the degrees of freedom for an N=9 sample size. 9 less 1 equals 8 (df=9-1=8).

The slope of the line passing through (-2, 3) and (2, 7) will be equal to 1.

Slope of the line is needed for the equation of the line and it is the measure of the degree of steepness of any given curve and If there are  two points (x₁, y₁) and (x₂, y₂) and we need the slope then the formula of finding the slope between these points is expressed as

m = (y₂ - y₁)/(x₂ - x₁)

where m is the slope between the points, (y₂ - y₁) is difference between the y coordinates and (x₂ - x₁) is the difference between the x coordinates.

Now the points given are (-2, 3) and (2, 7), so the difference between the coordinates is expressed as

The residual, if the cupric chloride had an etching rate of 5 [tex]\frac{\mu m}{min}[/tex], is given as follows:

-2 [tex]\frac{\mu m}{min}[/tex]

For a data-set, the definition of a residual is that it represents the difference of the actual output value by the predicted output value, that is:

Residual = Observed - Predicted.

The predicted etching rate for a temperature of x in this problem is given by the line of best fit, defined as follows:

y = 2 + 1/5x.

Hence, for a temperature of 25ºC, the estimated etching rate is given as follows:

y = 2 + 1/5(25) = 2 + 5 = 7.

The observed etching rate is of 5 units, hence the residual is calculated as follows:

Residual = Observed - Predicted.

Residual = 5 - 7

Residual = -2.
