the length of time to set up is 200 min. the time to paint each sign is 25 min. write an equation for this statement, then create a table of values and graph.

The values of x and y in the given system of equations are x = 4.00 and y = 5.00. These values are obtained by solving the system using the method of substitution.

The given system of linear equations is:

0.50x + 0.20y = 3.00 ...(Equation 1)

x + y = 9.00 ...(Equation 2)

To solve this system of equations, we can use the method of substitution or elimination. Let's solve it using the method of substitution:

From Equation 2, we can express x in terms of y:

x = 9.00 - y

Substituting this expression for x in Equation 1, we have:

0.50(9.00 - y) + 0.20y = 3.00

Expanding and simplifying:

4.50 - 0.50y + 0.20y = 3.00

-0.30y = -1.50

Dividing both sides by -0.30:

y = -1.50 / -0.30

y = 5.00

Now, substitute this value of y back into Equation 2 to find x:

x + 5.00 = 9.00

x = 9.00 - 5.00

x = 4.00

Therefore, the values of x and y in the given system of equations are x = 4.00 and y = 5.00.

Answer:

Ten thousands place. Brainliest please!!

Answer:

10,000 or ten thousands

Step-by-step explanation:

We can break the number down into expanded form

912,807 =

900,000 + 10,000 + 2000 + 800 + 7

The one in that number is actually 10,000

So the place value is in the 10,000's or ten thousands :)

Answer:

\(A=2000e^{0.085t}\)

Step-by-step explanation:

Make sure you understand the formula for continuous compounding first. The formula is:

\(A=Pe^{rt}\) where

A= Total

P= Principal (or the amount invested at beginning)

r= Interest rate (as a decimal)

t= Time (in years)

Note: e is an irrational mathematic number similar to π. Its value is around 2.72, but for these problems, you’ll need to use the version already on your calculator that will be called “\(e^{x}\).” On most calculators, it can be accessed by 2nd → ln.

Find the values that you are given:

A= What you are looking for

P= 2000

r= 8.5% as a decimal = 0.085

t= What you change

Plug these into the equation:

\(A=2000e^{0.085t}\)

This is the answer!

The probability that the mean time for the sample of 150 returns for this year is greater than 92 is 0.95907

Given,

Mean, \(\overline x\) = 90 minutes

standard deviation, \(\sigma\) = 14 minutes

to find probability that mean for sample 150 returns is greater than 92, \(P(\overline x > 92)\)

This means we need to find probability the related z-value of expected mean

where, \(z=\frac{\overline x-\mu_x}{\sigma_x}\)

Here,

\(\mu_x\)= expected mean =92

\(\sigma_x\)=standard deviation for new sample i.e. 150

\(\sigma_x\) can be calculated by formula,

\(\sigma_x=\frac{\sigma}{\sqrt{n}}\\\\\sigma_x=\frac{14}{\sqrt{150}}\\\\\sigma_x=1.143\)

Now,

\(z=\frac{90-92}{1.143}\\\\z=-1.749\)

Now,

\(P(\overline x > 92)\\\\=P(z > -1.749)\\\\=1-P(z < -1.749)\\\\=1-0.04093\\\\=0.95907\)

In above calculation, the z-value is  determined from the z-table.

Thus, the probability that mean is greater than 92 is 0.95907

Initially, the tank contains 60 kg of salt, calculated by multiplying the salt concentration (0.06 kg/L) by the water volume (1000 L).

In the given scenario, the tank starts with a known salt concentration and water volume. By multiplying the concentration (0.06 kg/L) with the water volume (1000 L), we find that the initial amount of salt in the tank is 60 kg.

After 4.5 hours, considering the rate of water entering and leaving the tank, the net increase in solution volume is 810 L. Multiplying this by the initial concentration (0.06 kg/L), we determine that the amount of salt in the tank after 4.5 hours is 48.6 kg.

As time approaches infinity, with a constant inflow and outflow of solution, the concentration of salt in the tank stabilizes at the initial concentration of 0.06 kg/L.

To get the specific values of y and x in this trapezium, we would need further data or equations based on variables. Their relation: x + y = 90

The fact that the sum of the angles in any quadrilateral, including a trapezium, is always equal to 360 degrees can be used to determine the values of the variables in this trapezium. Hence, we can write:

2y + 110 + 70 + 2x = 360

When we simplify this equation, we obtain:

2y + 2x = 180

When you divide both sides by 2, you get:

y + x = 90

According to this equation, the sum of the two variables, y and x, equals 90 degrees. The fact that this equation has an endless number of solutions prevents us from knowing the precise values of y and x from this equation alone.

The factored form of the quadratic equation 2x² + 25x + 50 is (2x + 5)(x + 10)

Factoring quadratics is a method of expressing the quadratic equation ax² + bx + c = 0 as a product of its linear factors as (x - k)(x - h), where h, k are the roots of the quadratic equation ax² + bx + c = 0.

Therefore, let's factor the equation 2x² + 25x + 50.

2x² + 25x + 50

The two numbers one can multiply and add to get 100 and 25 respectively are 20 and 5.

The relationship between two variables that begins as a direct correlation and then becomes an indirect correlation, or vice versa, is known as a nonlinear correlation.

A nonlinear correlation is when the relationship between two variables is not linear - that is, the correlation between them does not increase or decrease proportionately as one variable increases or decreases. Nonlinear correlations are important in research as they can suggest that a phenomenon is more complex than a linear correlation would indicate.

For example, if two variables have a direct linear correlation, then a small increase in one variable would result in a predictable increase in the other. However, with a nonlinear correlation, a small increase in one variable may result in a much larger or much smaller increase in the other. This suggests that other factors, not captured in the linear correlation, are influencing the relationship between the two variables.

Nonlinear correlations can be positive (the two variables increase or decrease together), negative (one variable increases as the other decreases, or vice versa), or both. Depending on the circumstances, the type of nonlinear correlation can have important implications for the research question being studied.

It is important to note that nonlinear correlations may be caused by a variety of factors, including chance, measurement errors, or the presence of an extraneous variable that has not been accounted for. As such, they should always be further investigated and not taken as an absolute conclusion.

\( \boxed{ \sf{ \: Area \: of \: a \: rectangular \: garden = 55 {ft}^{2}}}\)

Step-by-step explanation:

\( \star\) Let the width of a rectangular garden be 'w'

\( \star\) Length of a rectangular garden = 6 + w

\( \star\) Perimeter of a rectangular garden = 32 feet

\( \longrightarrow\) Finding the width of a rectangular garden :

\( \boxed{ \sf{ \: Perimeter \: of \: a \: rectangle \: = \: 2(length + width}}\)

\( \mapsto{ \text{32 = 2(6 + w + w)}}\)

\( \text{Step \: 1 \: : Collect \: like \: terms}\)

Like terms are those which have the same base

\( \mapsto{ \text{32 = 2(6 + 2w) }}\)

\( \text{Step \: 2 \: : Distribute \: 2 \: through \: the \: parentheses}\)

\( \mapsto{ \text{32 = 12 + 4w}}\)

\( \text{Step \: 3 \: : Swap \: the \: sides \: of \: the \: equation}\)

\( \mapsto{ \text{4w + 12 = 32}}\)

\( \text{Step \: 4 \: : Move \: 12 \: to \: right \: hand \: side \: and \: change \: its \: sign}\)

\( \mapsto{ \text{4w = 32 - 12}}\)

\( \text{Step \: 5 \: : Subtract \: 12 \: from \: 32}\)

\( \mapsto{ \sf{4w = 20}}\)

\( \text{Step \: 6 \: : Divide \: both \: sides \: by \: 4}\)

\( \mapsto{ \sf{ \frac{4w}{4} = \frac{20}{4}}}\)

\( \text{Step \: 7 \: : Calculate}\)

\( \mapsto{ \text{w = 5}}\)

Width of a rectangular garden = 5 feet

\( \longrightarrow\) Substituting / Replacing the value of w in 6 + w in order to find the length of a rectangular garden

\( \mapsto{ \sf{Length = 6 + w = 6 + 5 = \bold{11 \: feet} }}\)

\( \longrightarrow\) Finding the area of a rectangular garden having length of 11 feet and width of 5 feet :

\( \boxed{ \sf{Area \: of \: a \: rectangle = length \:∗ \: width}}\)

\( \mapsto{ \text{Area \: = \: 11 \: ∗ \: 5}}\)
