Answer:

The slope of the line that passes through (-95, 31) and (-94, 6) is -25.

Step-by-step explanation:

The equation of a line has the following format:

[tex]y = ax + b[/tex]

In which a is the slope.

Passes through the point (-95, 31).

When [tex]x = -95, y = 31[/tex]

[tex]y = ax + b[/tex]

[tex]31 = -95a + b[/tex]

Passes through the point (-94, 6).

When [tex]x = -94, y = 6[/tex]

[tex]y = ax + b[/tex]

[tex]6 = -94a + b[/tex]

We have to solve the following system:

[tex]31 = -95a + b[/tex]

[tex]6 = -94a + b[/tex]

We want to find a.

From the first equation

[tex]b = 31 + 95a[/tex]

Replacing in the second equation:

[tex]6 = -94a + 31 + 95a[/tex]

[tex]a = -25[/tex]

The slope of the line that passes through (-95, 31) and (-94, 6) is -25.

Final answer:

To maximize revenue from football game ticket sales and concessions, we create a revenue function based on ticket price adjustments and evaluate changes in quantity demanded. The optimal price and attendance are found by analyzing the combined revenue function, deriving it with respect to the number of price decreases, and finding the maximum value of this function.

Explanation:

To determine the ticket price that should be charged by the university to maximize revenue from football game attendance, we need to analyze the effect of price changes on the quantity demanded. We can create a revenue function based on the given figures and the assumptions that a decrease of $3 in ticket price increases attendance by 10,000 people, and each person spends an average of $4.50 on concessions.

Let x represent the number of $3 decreases in price from the original $18. The ticket price can then be expressed as P = 18 - 3x, and attendance as A = 40000 + 10000x. The revenue from ticket sales is R1 = P × A, which gives us R1 = (18 - 3x) × (40000 + 10000x). The concession revenue per person is $4.50, so total concession revenue is R2 = 4.50 × A, which gives us R2 = 4.50 × (40000 + 10000x).

To maximize total revenue R = R1 + R2, we need to find the maximum of the function R = (18 - 3x) × (40000 + 10000x) + 4.50 × (40000 + 10000x). To find this, we can use calculus to take the derivative of R with respect to x and find the value of x that makes this derivative zero. This will be the critical point which we can then test to confirm it provides a maximum.

Answer:

x=-5, 5

Step-by-step explanation:

To find the solutions, use inverse operations to rearrange the equation to be equal to 0.

[tex]x^2-9-16=16-16\\x^2-25=0[/tex]

Factor the equation and then set each equal to 0 to solve for x.

[tex]x^2-25=0\\(x+5)(x-5)=0[/tex]

x+5=0

x=-5

x-5=0

x=5

Answer:

[tex]\frac{4\sqrt{6x}}{2x}[/tex]

Explanation:

The problem we are given is

[tex]4\sqrt{\frac{3}{2x}}[/tex]

We can write the square root of a fraction as a fraction with a separate radical for the numerator and denominator; this gives us

[tex]4\times \frac{\sqrt{3}}{\sqrt{2x}}[/tex]

We can write the whole number 4 as the fraction 4/1; this gives us

[tex]\frac{4}{1}\times \frac{\sqrt{3}}{\sqrt{2x}}\\\\=\frac{4\sqrt{3}}{\sqrt{2x}}[/tex]

We now need to "rationalize the denominator."  This means we need to cancel the square root in the denominator.  In order to do this, we multiply both numerator and denominator by √(2x); this is because squaring a square root will cancel it:

[tex]\frac{4\sqrt{3}}{\sqrt{2x}}\times \frac{\sqrt{2x}}{\sqrt{2x}}\\\\=\frac{4\sqrt{3}\times \sqrt{2x}}{2x}[/tex]

When multiplying radicals, we can extend the radical over both factors:

[tex]\frac{4\sqrt{3} \times \sqrt{2x}}{2x}\\\\=\frac{4\sqrt{3\times 2x}}{2x}\\\\=\frac{4\sqrt{6x}}{2x}[/tex]

To find out how far the student can ride in 45 minutes, we calculate the speed of 0.15 miles per minute from the given 3 miles in 20 minutes, then multiply this speed by 45 minutes, resulting in a distance of 6.75 miles.

The student has stated that they can travel 3 miles in 20 minutes. To find out how far they can ride in 45 minutes, we need to calculate their riding speed and then apply it to the longer time period.

Step 1: Calculate the riding speed

The speed can be calculated by dividing the distance (3 miles) by the time (20 minutes), which gives us a speed of 0.15 miles per minute.

Step 2: Use the speed to determine the distance in 45 minutes

Now that we know the speed, we can multiply it by the new time period (45 minutes) to find the distance they can ride. That calculation is 0.15 miles/minute × 45 minutes = 6.75 miles.

When we check whether the answer is reasonable, we can notice that 45 minutes is a little more than twice 20 minutes, and since they can ride 3 miles in 20 minutes, it makes sense that they could ride more than twice that distance in 45 minutes, so our answer of 6.75 miles seems reasonable.

They can ride 6.75 miles in 45 minutes.

To find how far they can ride in 45 minutes, we can use the concept of average speed.

Given that they can ride 3 miles in 20 minutes, we can calculate their average speed as:

Average Speed = Distance / Time

Average Speed = 3 miles / 20 minutes

Average Speed = 0.15 miles per minute

Now, we can find how far they can ride in 45 minutes:

Distance = Average Speed x Time

Distance = 0.15 miles per minute x 45 minutes

Distance = 6.75 miles

Therefore, they can ride 6.75 miles in 45 minutes.

We have that for the Question, it can be said that  the area under the standard normal curve between z 1.5 and z 2.5 is

P(1.5 &2.5) =0.06

From the question we are told

How to find the area under the standard normal curve between z 1.5 and z 2.5?

Generally the equation for the probability is mathematically given as

P(1.5 &2.5) = P(Z < 2.5) - P(Z < 1.5)

Where

P(Z < 2.5) = 0.99

P(Z < 1.5) = 0.93

From Z Table

Therefore

P(1.5 &2.5) = P(Z < 2.5) - P(Z < 1.5)

The best way to group these ages into six intervals is from 40-44 to 65-69.

A frequency distribution table gives an idea about the data point or interval and its frequency.

The age of the Presidents given as

57 61 50 54 54 54 56 54 61 54 48 49 42 51 61 57 68 65 50 51 60 52 57 51 52 47 56 62 69 58 49 56 55 55 43 64 57 64 46 55 51 55 46

The smallest number ( age) is 42 and the largest number (age ) is 69

To make 6 intervals in this gap of 27 , each interval should be of length 5

Therefore the intervals will be

40-44

45-49

50-54

Final answer:

The best way to group the ages of U.S. Presidents into six intervals for a frequency table is by intervals of five years each, starting at age 42 and ending at age 71, to cover the entire range and maintain equal width for all intervals.

Explanation:

When grouping ages into intervals for a frequency table, it's best to have intervals that are of equal width and cover the entire range of data without overlap. For the ages of U.S. Presidents starting their terms, which range from 42 to 69, we could divide this range into six intervals in a way that makes sense for this data set.

First, find the range by subtracting the youngest age from the oldest: 69 - 42 = 27. Next, divide this range by the number of desired intervals (6), which gives us 4.5. We can round this to 5 to make the intervals more practical. Thus, each age interval will span 5 years. Starting at 42, the six intervals would be: 42-46, 47-51, 52-56, 57-61, 62-66, and 67-71.

This grouping covers all the ages and each interval is of equal width, making it easy to interpret the frequency table.

Answer:

b. 6.93 m.

Step-by-step explanation:

We have been given triangle ABC and we are asked to find the measure of a.

We will use law of sines to solve our given problem.

[tex]\frac{a}{\text{Sin}(A)}=\frac{b}{\text{Sin}(B)}=\frac{c}{\text{Sin}(C)}[/tex], where a, b and c are opposite sides of angle A, B and C respectively.

First of all, we will find the measure of angle B using angle sum property.

[tex]\angle A+\angle B+\angle C=180^{\circ}[/tex]

[tex]30^{\circ}+\angle B+90^{\circ}=180^{\circ}[/tex]

[tex]\angle B+120^{\circ}=180^{\circ}[/tex]

[tex]\angle B=180^{\circ}-120^{\circ}[/tex]

[tex]\angle B=60^{\circ}[/tex]

Upon substituting our given values in law of sines we will get,

[tex]\frac{a}{\text{Sin}(30^{\circ})}=\frac{12}{\text{Sin}(60^{\circ})}[/tex]

[tex]\frac{a}{0.5}=\frac{12}{\frac{\sqrt{3}}{2}}[/tex]

[tex]\frac{a}{0.5}=\frac{2*12}{\sqrt{3}}[/tex]

[tex]\frac{a}{0.5}*0.5=\frac{24}{\sqrt{3}}*0.5[/tex]

[tex]a=\frac{12}{\sqrt{3}}[/tex]

[tex]a=6.9282032302755\approx 6.93[/tex]

Therefore, the value of a is 6.93 meters and option 'b' is the correct choice.
