Let x = the number of reserved seats sold and y = the number of general seats sold.
1) x+y = 41,000 "41,000 people attended..."
2) $14(x)+$5(y) = $340,000 "The day's receipts were $340,000."
Rewrite equation 1) as x = y-41,000 and substitute into equation 2)
2a) 14(41,000-y)+5y = 340,000 Simplify and solve for y.
2a) 574,000-14y+5y = 340,000 Combine the y-terms.
2a) 574,000-9y = 340,000 Subtract 574,000 from both sides.
-9y = -234,000 Divide both sides by -9.
y = 26,000 and...
x = 41,000-26,000
x = 15,000
15,000 paid $14.00 for reserved seats.
26,000 paid $5.00 for general seats.

Find the Exponential Regression using the table. Write the initial amount, common ratio, and equation for the table.
Ipatiy [6.2K]

Answer:

Initial amount;

2110.6

Common ratio;

0.0201

Equation;

y=2110.6e^{0.0201x}

Step-by-step explanation:

In this scenario, the  month represents the independent variable x while the membership amount represents the dependent variable y.

The analysis is performed in Ms. Excel. The first step is to obtain a scatter plot of the data then finally inserting an exponential trend line to obtain the required equation.

The Ms. Excel output is shown in the attachment below. To obtain the initial amount we substitute x = 0 in the equation. On the other hand, the common ratio is the exponent in the equation.

What is the volume (in cubic units) of a sphere with a radius of 18 units? Assume that π = 3.14 and round your answer to the nea
Nataly [62]

Answer:

The volume of sphere is 24416.64\ cm^3.

Step-by-step explanation:

We have,

Radius of a sphere is 18 units.

It is required to find the volume of sphere.

The formula of the volume of sphere in terms of radius is given by :

V=\dfrac{4}{3}\pi r^3

Plugging all values in above formula

V=\dfrac{4}{3}\times 3.14\times (18)^3\\\\V=24416.64\ cm^3

So, the volume of sphere is 24416.64\ cm^3.

What is an algebraic equation for four times a number y is sixteen
Len [333]

4y=16

y is the variable. If you were to solve the equation you would write the equation as 4(4)=16.

If standard deviation of a given data is 5 and mean is 50 then coefficient of variation (C.V) is equal to *
torisob [31]

Answer:

10

Step-by-step explanation:

Coefficient of variation is a measure of dispersion, showing the variability of data in relation to the mean.

The Coefficient of variation compares the degree of variation between data points. The coefficient of variation is the ratio of mean to standard deviation. It is given by the formula:

Coefficient of variation = mean / standard deviation

Coefficient of variation = 50 / 5

Coefficient of variation = 10
