Answer:

250 adult tickets were sold

Step-by-step explanation:

Let A represent the number of adult tickets sold and  S the number of student tickets sold

Total tickets sold = A + S = 444

56 fewer student tickets than adult tickets means
S = A - 56

Substituting for s in the first equation,

A + S = 444

A + (A - 56) = 444

2A - 56 = 444

Add 56 to both sides:
2A - 56 + 56 = 444 + 56

2A = 500

A = 250

So 250 adult tickets were sold

The set of solutions for the linear system is x1 = 6, x2 = 3, and x3 = -4.

The linear system is given as follows:

x1 + x2 - x3 = 6

2x1 + x2 + 2x3 = 8

3x1 + 2x2 + 3x3 = 14

To solve this system, we will use the Gauss-Jordan elimination method. First, we will subtract twice the first equation from the second equation and three times the first equation from the third equation.

2x1 + x2 + 2x3 = 8

- 2(x1 + x2 - x3 = 6)

2x1 + x2 + 2x3 = 8

3x1 + 2x2 + 3x3 = 14

- 3(x1 + x2 - x3 = 6)

0x1 + 3x2 + 5x3 = 6

Next, we will subtract three times the second equation from the third equation.

3x1 + 2x2 + 3x3 = 14

- 3(0x1 + 3x2 + 5x3 = 6)

3x1 + 2x2 - 2x3 = 8

Finally, we will divide the first equation by 1, the second equation by 3, and the third equation by -2.

x1 + x2 - x3 = 6

/ 1

x1 + (1/3)x2 + (5/2)x3 = 3

(-1/2)x1 + x2 + x3 = -4

The set of solutions for the linear system is x1 = 6, x2 = 3, and x3 = -4.

The best numerical descriptive measure for comparing average store sales by region would be the mean or average.

This measure would provide an accurate representation of the overall store sales across the entire region and would allow the manager to easily identify which region has the lowest store sales.

Additionally, the median and mode could also be used as descriptive measures to compare the store sales by region.

For example, if there is a single store with particularly high sales, the mean will be heavily influenced by this one store. The median and mode would be more likely to provide a better representation of the overall sales across the region, as they are not as heavily influenced by extreme values.

The resulting binary representation of 100 is 1100100.

The recursive method for displaying the binary equivalent of a decimal number is based on the binary representation of integers, which is expressed by the formula:

Decimal number = [tex](2^n * bn) + (2^n-1 * bn-1) + ... + (2^0 * b0)[/tex]

where n is the number of bits in the binary representation, and bn is the value at each bit position (either 0 or 1).

To calculate the binary equivalent of a decimal number, the method works by first calculating the largest power of two (2^n) that is less than or equal to the decimal number. The remainder of the decimal number is then calculated (Remainder = Decimal number - 2^n). This remainder is then recursively used to calculate the binary equivalent of the remainder. This process is repeated until the remainder is less than or equal to 2^0, at which point the binary representation can be determined.

For example, to calculate the binary equivalent of 100, the largest power of two that is less than or equal to 100 is 2^6 (64), so the remainder is 100 - 64 = 36. The binary equivalent of 36 is then calculated recursively, and the resulting binary representation of 100 is 1100100.

the random variable x is the number of occurrences of an event over an interval of 10 minutes. it can be assumed the probability of an occurrence is the same in any two time periods of an equal length. it is known that the mean number of occurrences in 10 minutes is 5.3.

A Poisson process is a statistical model used to describe the number of occurrences of an event over a fixed interval of time or space. It has the following properties:

The events are independent, meaning that the occurrence of one event does not affect the probability of another event happening.

The average rate of occurrences is constant over time and is equal to the rate parameter of the Poisson distribution.

The probability of having n events in a fixed interval of time is given by the Poisson probability formula:

P(n) = (λ^n * e^-λ) / n!

where λ is the rate parameter and n! is the factorial of n.

Given the mean number of occurrences in 10 minutes is 5.3, it can be assumed that the rate parameter is 0.53 occurrences per minute. This means that, on average, 0.53 events are expected to occur in each minute. Since the Poisson process is memoryless, this rate is constant over time and the mean number of occurrences in any 10-minute interval will be 5.3.

A) The Fibonacci sequence is a set of numbers that starts with a one or a zero, followed by a one, and proceeds based on the rule that each number (called a Fibonacci number) is equal to the sum of the preceding two numbers. The Fibonacci numbers are: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181, 6765, 10946, and so on. To express 52, 143, 13 and 88 as a sum of distinct, nonconsecutive Fibonacci numbers, we can use the following calculations.

For 52, the sum is 13 + 34. 13 is the 8th Fibonacci number and 34 is the 9th Fibonacci number. By adding these two numbers, we get 52.

For 143, the sum is 89 + 34 + 13 + 8. 89 is the 11th Fibonacci number, 34 is the 9th Fibonacci number, 13 is the 8th Fibonacci number and 8 is the 7th Fibonacci number. By adding these four numbers, we get 143.

For 13, the sum is 8 + 5. 8 is the 7th Fibonacci number and 5 is the 6th Fibonacci number. By adding these two numbers, we get 13.

Step-by-step explanation:

The initial value for Marcos to the grand canyon is 400 miles.

Each term in a linear equation has an exponent of 1, and when this algebraic equation is graphed, it always produces a straight line. It is called a "linear equation" for this reason.

Both linear equations with one variable and those with two variables exist.

Given Marco is driving to the grand canyon. His distance from the Grand Canyon decreases by 150 mi every 3h.

We know that every 3 hours that distance decreases by 150 miles, then the distance decreased by the hour is:

150mi/3h = 50mi/h

since the distance is reducing we can take the rate of change negative,

so rate of change = -50 mi/h

and y = distance from the Grand Canyon

x = the number of hours he drives,

so the equation of slope is y = mx + c

where m = rate of change and c is the initial value at x = 0

m = -50 mi/h

y = -50x + c

And we know that after 4 hours the distance is 200 miles, then we can replace that to get:

200mi = (-50 mi/z)*4h + c

200mi = -200mi + c

200mi + 200mi = c  =400mi

equation is y = -50x + 400

Hence the initial value is 400 miles.

The sampling distribution of xM - xB is normally distributed with a mean of 18 mg/dl and a standard deviation of 35.4 mg/dl.

The sampling distribution of xM - xB is a normal distribution. This can be calculated by subtracting the mean of the men (188mg/dl) from the mean of the boys (170mg/dl), which gives a mean of 18 mg/dl. To calculate the standard deviation, we first calculate the standard deviation of the men (41 mg/dl) and the boys (30mg/dl). Then we use the formula: standard deviation of xM - xB = sqrt(standard deviation of men^2 + standard deviation of boys^2). This gives us a standard deviation of 35.4mg/dl. To calculate the probability of getting a difference in sample means xM - xB that's less than 0 mg/dl, we use the z-score formula: z = (x-mean)/standard deviation. Plugging in x = 0, mean = 18 and standard deviation = 35.4 gives us a z-score of -0.5197. Using a z-table, this gives us a probability of 0.3085. It should not be a surprise if the sample mean cholesterol for the 14 - year - olds exceeds the sample mean for the men as the mean cholesterol level for the boys is lower than the men.

[tex]\theta = tan^{-1} (0.95833) = 43.78^\circ[/tex]

Answer
[tex]= 43.78^\circ[/tex]

The angle of elevation is given by the trigonometric relation and θ = 73.40°

What are trigonometric relations?

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Given data ,

Let the angle of elevation be represented as E = θ

Now , the measure of the altitude = 46 m

The measure of the hypotenuse = 48 m

And , the angle of elevation is given by the trigonometric relation ,

sin θ = opposite / hypotenuse

On simplifying , we get

sin θ = 46 / 48

sin θ = 0.958333

Taking inverse on both sides , we get

θ = sin ⁻¹ ( 0.958333 )

θ = 73.40°

Hence , the angle of elevation is 73.40°

Subject to:

2P + E <= 2400 (hours of machine press time available)

4P + 5E <= 6000 (hours of fabrication time available)

2P + 3E <= 3300 (hours of assembly time available)

P + E <= 1500 (hours of testing time available)

P, E >= 0 (non-negativity constraints)

Where P is the number of propane grills and E is the number of electric grills produced.

b. The feasible region for this problem is a polygon with vertices (0, 0), (600, 0), (300, 900), (0, 1200). This region represents the combination of P and E that satisfies all the constraints.

c. To determine the optimal solution using level curves, we can start by plotting the feasible region and then finding the level curve that represents the maximum profit. The level curve would be a straight line with slope equal to $320/$260 (the ratio of price per unit for the two types of grills).
