The value for variable m in equation Z = m + mwg is m = Z - mwg.

What are variables?

The alphabetic character that expresses a numerical value or a number is known as a variable in mathematics. A variable is used to represent an unknown quantity in algebraic equations.

The equation is given as -

Z = m + mwg

To get the value for variable m, subtract mwg from Z and take it to left-hand side.

Z - mwg = m

Reverse the equation and get it in right form -

The equation obtained is -

m = Z - mwg

Therefore, the value is m = Z - mwg .

Kelly can run 1/2 mile in 3 minutes. 1/6 mile Kelly run in 1 minute if he runs at the same pace the entire time.

The word "mile" is derived from the Latin "mille passus," which means "one thousand paces." The English Parliament established the Mile at eight furlongs (one furlong is 660 feet) in 1592. A mile is a unit of measurement that is standardised as exactly 1609.344 metres by the International agreement in 1959. A mile is exactly equivalent to 5280 feet, or 1760 yards.

Kelly can run 1/2 mile in 3 minutes so the ratio is 1/2 mile per 3 minutes

Answer:

p = 1

Step-by-step explanation:

since (p, 2p + 1) is a solution then it makes the equation true.

substitute x = p and y = 2p + 1 into the equation and solve for p

11p - 2(2p + 1) = 5 ← distribute parenthesis and simplify left side

11p - 4p - 2 = 5

7p - 2 = 5 ( add 2 to both sides )

7p = 7 ( divide both sides by 7 )

p = 1

The most accurate comment about the graph  data is: "China's steel production is increasing while its major competitors' production is declining."

Academics are using graphs to logically chart or graphically depict events or quantities. A graph point is a common way to depict how different things interact. The non-linear storage structure known as a graph is made up of nodes, also referred to as vertices, and lines. Glue ought to be used to connect the edges, also known as nodes , respectively.  (4.5).

Here,

The most accurate comment about the data is: "China's steel production is increasing while its major competitors' production is declining."

This is because the graph shows that China's steel production has been steadily increasing since the early 2000s, while the steel production of other major producers such as Japan, the United States, and Germany has been declining or stagnant. This trend is particularly evident after the global financial crisis of 2008-2009.

While it is true that Japan's steel production has increased and shows no signs of decreasing, this comment does not address the overall trend of declining steel production among major producers.

The other two comments are not accurate. The statement "By 2009, China’s tons of steel produced per US million ($) GDP was 50, about 10 tons less than Japan’s all-time high" is not supported by the graph, as there is no information about tons of steel produced per US million ($) GDP on the graph.

Answer: The probability of picking each type of player at random depends on the number of players of each type on the field. If the number of players of each type is not specified, it is not possible to determine the probability of picking each type of player at random.

Step-by-step explanation:

The requried, inverse of a function is a function for which the values or the domain and the range are interchanged. Option C is correct.

The inverse of a function is a new function that results from interchanging the input (domain) and output (range) of the original function.

Here,
if f(x) is a function, its inverse function is denoted by f⁻¹(x), and it is defined such that f⁻¹(y) = x, where y = f(x) is the original function.

For example, if f(x) = 2x + 3, the inverse function f⁻¹(x) is found by interchanging x and y, and solving for y:

x = 2y + 3

2y = x - 3

y = (x - 3)/2

Therefore, f⁻¹(x) = (x - 3)/2, and it is the inverse of the original function f(x). Note that the domain and range of the inverse function are interchanged with respect to the original function.

Determine if the equation is linear by calculating the slope between each pair of (x, y) points:

[tex]\implies \text{Slope}\;(m)=\dfrac{565-1090}{7-2}=-105[/tex]

[tex]\implies \text{Slope}\;(m)=\dfrac{1090-1300}{2-0}=-105[/tex]

As the slope is the same, the equation is linear.

The initial purchase price of the computer was $1,300. So when x = 0, y = 1300.  Therefore, the y-intercept is 1300.  

We have already calculated the slope as -105.

They result in the following when combined: An equation, some data, and a mathematical function Values, parameters, and mathematical operations like additions, subtractions, multiplications, and divisions can all be found in a declaration of fact. Different phrases and words can be compared and evaluated.

Here,

To prove that the value of the expression doesn't depend on x, we need to show that the x-term disappears when we simplify the expression.

Starting with:

(3/5x² - 0.4cy - 1.5y + 1) - (y² - 2/5xy + 0.6x²)

Distributing the negative sign in the second set of parentheses:

3/5x² - 0.4cy - 1.5y + 1 - y² + 2/5xy - 0.6x²

Rearranging the terms by collecting like terms, we get:

(3/5 - 0.6)x² + (2/5y - 0.4c)y - y²- 1.5y + 1

Simplifying further, we get:

(-0.1)x² + (0.4y - 0.4c)y - (y² + 1.5y - 1)

Notice that there is no x-term in the final expression, which means that the value of the expression doesn't depend on x.

Therefore, we have proved that the value of the expression (3/5x²-0.4cy-1.5y+1)-(y²-2/5xy+0.6x²) doesn't depend on x.

Answer:

y = 4x - 3

Step-by-step explanation:

y = mx + b

The m is the slope and the b is the y-intercept.

The slope is 4.  If you start at the point (0,-3) and go up 4 units and then 1 unit to the right, you will be back on the line at point (2,4) The slope is the rise over the run.  The rise is 4 and the run is 1.  4/1 = 4.

The slope (m) is 4.

The y-intercept is where the line crosses the y axis.  It crosses at (0,-3)

The y-intercept (b) is -3

Plug 4 in for m and -3 in for b

y = mx + b

Answer: To find the principal value of arctan(-1.44) to the nearest minute, we first need to find the value of arctan(-1.44) in radians.

We can use the arctan function in a mathematical software or calculator to find the result. The value of arctan(-1.44) in radians is approximately -0.8623.

Next, we convert the result from radians to minutes, by multiplying the radians by 180/π and then multiplying the result by 60.

-0.8623 * 180/π * 60 = -50.47 minutes

So the principal value of arctan(-1.44) to the nearest minute is approximately -50 minutes.

Using percentages we know that the rate of commission of the salesperson based on the net sales is 15.5%.

A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and sometimes "pc" is also used, the percent symbol, "%," is frequently used to indicate it.

A % is a number without boundaries and without a standard measurement.

So, calculate as follows:

5880/100 * 11.5 = 676.2

Now,

5880 - 676.2 = 5,203.8

Now, calculate the percentage as follows:

806.59/5,203.8 * 100

15.5%

Therefore, using percentages we know that the rate of commission of the salesperson based on the net sales is 15.5%.
