The equation that expresses the combined weight of the tank and algebrol in pounds, w, in terms of the number of gallons of algebrol in the tank, v, is:

w = 8.8v + 126.5

The weight of the algebrol per gallon is given as 8.8 pounds/gallon. Therefore, the weight of the algebrol in the tank is 8.8 times the number of gallons, which is represented by 8.8v.

Additionally, we are given that the combined weight of the tank and algebrol is 126.5 pounds. This weight includes the weight of the tank itself, which is independent of the number of gallons.

Hence, we add the weight of the tank to the weight of the algebrol, resulting in the equation: w = 8.8v + 126.5.

This equation allows us to calculate the combined weight (w) based on the number of gallons (v) of algebrol in the tank.

Therefore, the combined weight, w, of the tank and algebrol in pounds can be calculated by multiplying the number of gallons, v, of algebrol by 8.8 and adding 126.5.

Their net pay will be the same as their gross pay, and option (a) No federal income taxes are withheld is the correct answer.

Based on the given tax table, if a single person earns a gross biweekly salary of $780 and claims 6 exemptions, the federal income tax withheld is $0.

To determine the net payback of a person with a gross biweekly salary of $780 and 6 exemptions, we need to use the federal tax table.

Unfortunately, the table is not provided in the question, so we cannot determine the exact amount of federal income tax that will be withheld.

Assuming that the person is paid on a biweekly basis, their annual gross salary would be $20,280 ($780 x 26).

Using the 2021 federal tax tables for single filers, a person with an annual gross salary of $20,280 and 6 exemptions would have a federal income tax liability of $0.

Based on the information provided, it appears that the person's net pay would not change due to federal income tax withheld, as they would not owe any federal income taxes.

Adding a derivational suffix to a word often changes the part of speech is true.

What is derivational suffix ?

A derivational suffix is a type of affix that is added to the end of a base word to create a new word with a different meaning, often a different part of speech.

For example, adding the derivational suffix "-ness" to the base word "kind" creates the new word "kindness," which is a noun that refers to the quality or state of being kind. Similarly, adding the derivational suffix "-able" to the base word "value" creates the new word "valuable," which is an adjective that describes something that is worth a lot.

Derivational suffixes can change the meaning and function of a word, and they are often used to create new words in English. Some common derivational suffixes include "-er," "-able," "-ness," "-ful," "-ish," and "-ize."

You can buy 5 CD's

Step-by-step explanation:

Equation:

\(11.99x \leq59.95x \leq5\)

Answer:

5 CDS

Here would be the inequality - \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/

So if you only have $59.95 in your wallet, you can only buy something equivalent to 59.95 or less. If each CD is 11.99, how many CDs can you buy before going over your limit? You can do 59.95÷11.99 to find this answer. It will equal 5. So you can only buy 5 CDs or less. So the equations would be

The equation for y given that the rate of change of y with respect to x is one-half times the value of y is y = 2e^(x/2), where x is any real number.

Given that the rate of change of y with respect to x is one-half times the value of y and that the value of x is 0, find the equation for y.To solve this problem, we need to integrate both sides. \(dy/dx = (1/2)y, d/dy [ ln |y| ] = 1/2 dx + C\), where C is a constant of integration.

If we now assume that\(y > 0, ln y = x/2 + C, y = e^(x/2 + C) = e^C * e^(x/2\)).But we don't know the value of the constant, C, yet. To determine the value of C, we need to use the initial condition given by the question, namely that when\(x = 0, y = 2.C = ln 2, y = 2e^(x/2).\)Therefore, the equation for y when x = 0 is y = 2.

The price per T-shirt should be at least $15 to achieve a profit of $250.

To calculate the price per T-shirt that will yield a profit of at least $250, we need to consider the cost of production, the desired profit, and the number of shirts to be sold.

Given that the cost to make each T-shirt is $10, and we want to sell 50 shirts, the total cost of production would be 10 * 50 = $500.

Now, let's calculate the minimum revenue needed to achieve a profit of $250. We add the desired profit to the total cost of production: $500 + $250 = $750.

Finally, to determine the price per T-shirt, we divide the total revenue by the number of shirts: $750 ÷ 50 = $15.

Therefore, to make a profit of at least $250, the price per T-shirt should be set at $15.

By selling each T-shirt for $15, the total revenue would be $15 * 50 = $750. From this revenue, we subtract the total production cost of $500 to calculate the profit, which amounts to $750 - $500 = $250. Thus, by charging $15 per T-shirt, the desired profit of $250 is achieved.

Using the Z-table, we can determine the probability that a sample of 120 steady smokers spend between $19 and $21 is 0.986.

We have given that,

A sample is consider as survay to determine mean unt of steady smokers.

sample size (n) = 120

sample mean (X-bar ) = $20

standard deviations of sample (s) = $5

confidence interval is (19,21)

firstly we find the Z-Score value for given sample , C.I = X-bar +- Z(s/√n)

=> either 19 = 20 + Z(5/√120) or

21 = 20-Z(5/√220)

Answer:

it is a statistical measure of the relationship between two variables that indicates the extent to which the variables change together in the same or opposite direction. Correlation does not imply causation, meaning that a correlation between two variables does not necessarily mean that one variable causes the other.

Based on this definition, the correct answer is b. Increasing values of X go with either increasing or decreasing values of Y. A correlation exists between two variables when both variables increase or decrease together. This statement captures the idea that correlation can be positive or negative, and that it reflects a linear relationship between two variables.

Step-by-step explanation:

a is wrong because it only describes positive correlation, not negative correlation.

c is wrong because it confuses correlation with consistency. Correlation does not require that higher values of X always go with higher or lower values of Y, only that they tend to do so on average.

d and f are wrong because they assume causation from correlation, which is a logical fallacy.

e is wrong because it contradicts itself. It says that increasing values of X go with increasing values of Y, which is positive correlation, but then it says that a correlation exists when both variables decrease together, which is negative correlation.

If X is correlated with Y, it implies a predictive statistical relationship between X and Y. This correlation can be positive or negative implying respective increase or decrease in values of both variables. But, this correlation doesn't prove causation.

If X is correlated with Y, it indicates a statistical relationship between the two variables, X and Y. This relationship can be positive or negative. If it is a positive correlation, as X increases, Y will also increase and similarly, as X decreases, Y will also decrease. Contrarily, in a negative correlation, as X increases, Y decreases and vice versa. However, it is important to understand that correlation does not imply causation. That is, if X and Y are correlated, it does not necessarily mean that changes in X cause changes in Y or vice versa. It only means that they move in a predictable manner relative to each other.

Hence, option C is true.

Step-by-step explanation:

Given the system of equations

\(\begin{bmatrix}4x+7y=60\\ -4x+7y=-4\end{bmatrix}\)

adding both the equations

\(-4x+7y=-4\)

\(+\)

\(\underline{4x+7y=60}\)

\(14y=56\)

so the system of equations becomes

\(\begin{bmatrix}4x+7y=60\\ 14y=56\end{bmatrix}\)

solve 14y for y

\(14y=56\)

Divide both sides by 14

\(\frac{14y}{14}=\frac{56}{14}\)

Simplify

\(y=4\)

\(\mathrm{For\:}4x+7y=60\mathrm{\:plug\:in\:}y=4\)

\(4x+7\cdot \:4=60\)

\(4x+28=60\)

Subtract 28 from both sides

\(4x+28-28=60-28\)

Simplify

\(4x=32\)

Divide both sides by 4

\(\frac{4x}{4}=\frac{32}{4}\)

\(x=8\)

Therefore, the solution of the system of equations be:

\(x=8,\:y=4\)
