Answer:

180 tickets

Step-by-step explanation:

750 + 150 = 900 they will have to make

900/5 = 180 tickets

To raise at least $750, the seventh-grade class needs to sell a minimum of 180 tickets, priced at $5 each, to cover the fundraising goal and the $150 auditorium rental cost.

Given that,

Seventh-grade class is putting on a variety show to raise money.

The auditorium rental cost is $150.

Each ticket is priced at $5.

The goal is to raise at least $750.

Denote the number of tickets they need to sell as "x".

The revenue generated from ticket sales can be calculated by multiplying the number of tickets sold (x) by the ticket price ($5),

Which gives us 5x dollars.

Now since,

Total revenue from ticket sales - Auditorium rental cost ≥ Fundraising goal

Therefore,

5x - 150 ≥ 750

Add 150 to both sides:

5x ≥ 900

Divide both sides by 5 to solve for x:

x ≥ 180

Since the seventh-grade class cannot sell a fractional number of tickets,

Hence,

They need to sell at least 180 tickets to raise at least $750 and cover the auditorium rental cost.

Step-by-step explanation:

Z-score:

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question:

The applicant with the highest z-score should be chosen.

Tobias:

Score of 84.5, in a version with mean 66.9 and standard deviation 11. His z-score is found when [tex]X = 84.5, \mu = 66.9, \sigma = 11[/tex]

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{84.5 - 66.9}{11}[/tex]

[tex]Z = 1.6[/tex]

Kiersten:

Score of 281.8, in a version with mean 261 and standard deviation 26. His z-score is found when [tex]X = 281.8, \mu = 261, \sigma = 26[/tex].

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{281.8 - 261}{26}[/tex]

[tex]Z = 0.8[/tex]

Pierce:

Score of 7.69, version with mean 7.2 and standard deviation 0.7. His z-score is found when [tex]X = 7.69, \mu = 7.2, \sigma = 0.7[/tex].

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{7.69 - 7.2}{0.7}[/tex]

[tex]Z = 0.7[/tex]

Due to the higher z-score, Tobias should be offered the job.

Step-by-step explanation:

Answer:

Equations:

[tex]4H + 3P = 13.75[/tex]

[tex]2H + 5P = 11.25[/tex]

[tex]H = 2.50[/tex] --- Hot dog

[tex]P = 1.25[/tex] --- Pretzel

Step-by-step explanation:

Represent hot dogs with H and Pretzels with P.

For Tina:

[tex]4H + 3P = 13.75[/tex]

For Doug:

[tex]2H + 5P = 11.25[/tex]

Solving for the price of both items:

We have:

[tex]4H + 3P = 13.75[/tex] --- (1)

[tex]2H + 5P = 11.25[/tex] --- (2)

Multiply (2) by 2

2 * ([tex]2H + 5P = 11.25[/tex])

-------------------

[tex]4H + 10P = 22.50[/tex] --- (3)

Subtract (3) from (1)

[tex]4H + 3P = 13.75[/tex]

[tex]4H + 10P = 22.50[/tex]

----------------------

[tex]4H - 4H + 3P - 10P = 13.75 - 22.50[/tex]

[tex]3P - 10P = 13.75 - 22.50[/tex]

[tex]-7P = -8.75[/tex]

Solve for P

[tex]P = \frac{-8.75}{-7}[/tex]

[tex]P = 1.25[/tex]

Substitute 1.25 for P in (2)

[tex]2H + 5P = 11.25[/tex]

[tex]2H + 5 * 1.25 = 11.25[/tex]

[tex]2H + 6.25 = 11.25[/tex]

Collect Like Terms

[tex]2H = 11.25-6.25[/tex]

[tex]2H = 5[/tex]

Solve for H

[tex]H = \frac{5}{2}[/tex]

[tex]H = 2.50[/tex]

The point (4, 3) is on the graph of this exponential model.

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

We can use the given information to form two equations with two unknowns (a and b) and solve for them.

From the first data point (2, 3 km):

y = a b^x

3 = a b^2

From the second data point (3, 9 km):

y = a b^x

9 = a b^3

Dividing the second equation by the first equation:

9/3 = (a b³) / (a b²)

3 = b

Substituting b = 3 into the first equation:

3 = a x 3²

a = 1/9

So the exponential model is y = (1/9) x 3^x.

To find another point on the graph of this exponential model, we can choose a value for x and calculate y.

Let's try x = 4:

y = (1/9) x 3^4

y = 1 x 3/3 x 3/3 x 3/3 x 3/9

y = 3

Therefore,

The point (4, 3) is on the graph of this exponential model.
