Answer:

To break even the local arena must sell approximately 70,589 tickets. They would have a loss of $47625.

Step-by-step explanation:

The cost per night of the Icey blades contract can be expressed as a function of the gate receipts, with the flat cost added by 40% of all the gate receipts sold. This expression is shown below:

[tex]cost(x) = 60000 +0.4*x[/tex]

Since each ticket costs $1.25, then the revenue of the arena can be shown as:

[tex]revenue(x) = 1.25*x[/tex]

In order to break even the revenue must be equal to the cost, so:

[tex]revenue(x) = cost(x)\\1.25*x = 60000 + 0.4*x\\1.25*x - 0.4*x = 60000\\0.85*x = 60000\\x = \frac{60000}{0.85} = 70,588.24[/tex]

To break even the local arena must sell approximately 70,589 tickets.

If the average attendance was 7500 per night, the profit would be:

[tex]profit = revenue(7500) - cost(7500)\\profit = 1.25*7500 - 60000 + 0.4*7500\\profit = 9375 - 60000 + 3000\\profit = -47625[/tex]

They would have a loss of $47625

Given

16[tex]y^{4}[/tex] - 256[tex]x^{12}[/tex] ← factor out 16 from each term

= 16([tex]y^{4}[/tex] - 16[tex]x^{12}[/tex] ) ← difference of squares which factors in general as

a² - b² = (a - b)(a + b), thus

[tex]y^{4}[/tex] - 16[tex]x^{12}[/tex]

= (y² )² - (4[tex]x^{6}[/tex] )²

= (y² - 4[tex]x^{6}[/tex] )(y² + 4[tex]x^{6}[/tex] )

Now y² - 4[tex]x^{6}[/tex] ← is also a difference of squares

= y² - (2x³)²

= (y - 2x³)(y + 2x³)

Thus

16[tex]y^{4}[/tex] - 256[tex]x^{12}[/tex]

= 16(y - 2x³)(y + 2x³)(y² + 4[tex]x^{6}[/tex] )

Answer:

Step-by-step explanation:

The requried, race car will travel approximately 1100 feet in 5 seconds at a constant speed of 150 miles per hour.

To find out how many feet a race car traveling at a constant speed of 150 miles per hour travels in 5 seconds, we need to convert the given speed from miles per hour to feet per second.

There are 5280 feet in a mile, and there are 3600 seconds in an hour.

First, let's convert 150 miles per hour to feet per second:

= 150 miles/hour * 5280 feet/mile / 3600 seconds/hour
= 220 feet/second (approximately)

Now, we can calculate the distance traveled by the race car in 5 seconds:

Distance = Speed * Time

Distance = 220 feet/second * 5 seconds

Distance = 1100 feet

Therefore, the race car will travel approximately 1100 feet in 5 seconds at a constant speed of 150 miles per hour.

Answer:

Infinate

Step-by-step explanation:

The normal distribution is dependent on the standard deviation and what the value of the mean is. But this then implies that a different standard deviation or a different mean leads to a different normal distribution. Making there many possibilities for normal distributions.

There are infinitely many possibilities for normal distributions as there are indefinitely many values possible for both the mean and standard deviation.

Answer:

1.02% probability of the stick's weight being 2.44 oz or greater

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

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:

[tex]\mu = 2, \sigma = 0.19[/tex]

What is the probability of the stick's weight being 2.44 oz or greater?

As a decimal, this is 1 subtracted by the pvalue of Z when X = 2.44. So

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

[tex]Z = \frac{2.44 - 2}{0.19}[/tex]

[tex]Z = 2.32[/tex]

[tex]Z = 2.32[/tex] has a pvalue of 0.9898

1 - 0.9898 = 0.0101

1.02% probability of the stick's weight being 2.44 oz or greater

Answer:

Hello There. ♡ The correct answer is: f(x) = -|x-1|

The parent function is f(x) = |x|

Then the function is reflected over the x-axis, so the f(x) will become -f(x)'. The function will become: 

f(x) = -|x| 

-f(x)' = |x|

 f(x)' = -|x|

After that, the function is translated 1 unit to the right. That mean x will become x'-1. The function will become: 

 f(x) = -|x|

 f(x) = -|(x'-1)|

 f(x) = -|x'-1|

Answer:

Graph A

Step-by-step explanation:

Say that the car rental rate stands for c dollars ( $ ). We know that Jamal's trip lasts for 4 days, paying $ 24 in expenses for gas, and $ 128 for taxi services. Based on these requirements for his trip the question asks for a graph that models this situation, but lets start with the inequality.

______

The big key here is the part " which graph shows the range of car rental rates that would be cheaper than the taxi service. " Our inequality must thus have the variable " c " on the same side as the payment for gas ($ 24 ), and must be less than the taxi service ( $ 128 ), or in other words a less than sign. Another point is the car rental rate. We know it stands for c, but it is dependent on the number of days. Hence we can conclude the following inequality,

24 + 4c < 128 - Subtract 24 from either side,

4c < 104 - Divide by 4 on either side, isolating c,

c < 26

The range of car rental rates that would be cheaper than the taxi service should be { c | 0 ≤ c < 26 }, knowing variable c stands for the car rental rates.

______

The graph that models this range should be the first one, option A. This graph is not accurate however, as it extends infinitely in the negative direction, and you can't have negative money, or rather be in debt - in this situation.

Answer:

The correct answer is B.

Step-by-step explanation:

Giving the following information:

Job:

Direct materials= $2,000

Direct labor= $400

Machine-hours= 900 mh

Company:

Manufacturing overhead costs $45,000

Machine-hours 100,000 mh

Selling price= 40% markup of total manufacturing costs

First, we need to calculate the predetermined overhead rate to allocate overhead:

Predetermined manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base

Predetermined manufacturing overhead rate= 45,000/100,000

Predetermined manufacturing overhead rate= $0.45 per machine hour

Now, we can calculate the total cost and the selling price:

Total cost= 2,000 + 400 + 0.45*900= $2,805

Selling price= 2,805*1.4= $3,927

Answer:

the first term is 4

Step-by-step explanation:

Given

G(3) = 36

G(6) = 972

Solution:

General formula for geometric series

G(x) = AB^x

From given data: G(6)/G(3) = 972/36 = 27

From formula: G(6)/G(3) = AB^6/(AB^3) = B^3

Therefore

B^3 = 27

B=3

Hence

G(1) = AB^1 = AB^3/B^2=36/3^2=36/9=4

Ans: the first term is 4

Answer:

a₁ = 4

Step-by-step explanation:

The n th term of a geometric series is

[tex]a_{n}[/tex] = a₁ [tex]r^{n-1}[/tex]

where a₁ is the first term and r the common ratio

Given a₃ = 36 and a₆ = 972 , then

ar² = 36 → (1)

a[tex]r^{5}[/tex] = 972 → (2)

Divide (2) by (1)

[tex]\frac{ar^{5} }{ar^{2} }[/tex] = [tex]\frac{972}{36}[/tex] , that is

r³ = 27 ( take the cube root of both sides )

r = [tex]\sqrt[3]{27}[/tex] = 3

Substitute r = 3 into (1)

9a = 36 ( divide both sides by 9 )

a = 4

The first term is 4

Answer B is the correct one: a curved line that can be increasing or decreasing.

Step-by-step explanation:

Exponential functions are one-to-one functions, which means that cannot have a U shape. Also, they are not a straight line, since they grow of decrease exponentially (based on a fixed numerical base with the variable as the exponent) They can represent exponential growth showing a curve with increasing values as we move from left to right, or can represent exponential decay showing a curve with decreasing values as we move from left to right.

Answer:

Where:

[tex]a[/tex] - First term of the series, dimensionless.

The quadratic equation, y = x² + 3x + 1 has two real roots.

In a quadratic equation of the form, ax² + bx + c = 0, the nature of the roots depends upon the value of the discriminant (D), which is calculated by the formula, D = b² - 4ac.

If the value of D > 0, the equation has real and distinct roots.

If the value of D = 0, the equation has real and equal roots.

If the value of D < 0, the equation has imaginary roots.

In the question, we are given an equation y = x² + 3x + 1 and are asked to say how many real roots it has.

To find the roots, we first equate y to 0.

∴ y = x² + 3x + 1 = 0.

Now comparing the equation x² + 3x + 1 to the standard equation ax² + bx + c, we get a = 1, b = 3, and c = 1.

Now, the nature of the roots depends upon the discriminant (D),

D = b² - 4ac = 3² - 4.1.1 = 9 - 4 = 5.

∵ Discriminant (D) > 0, the quadratic equation, y = x² + 3x + 1 has both its root real and distinct.

∴ The quadratic equation, y = x² + 3x + 1 has two real roots.
