Answer:

202 tickets for adults were sold and 70 tickets for children are sold.

Step-by-step explanation:

Solve this question using simultaneous linear equation.

•Let the number of tickets sold for adults be a

•Let the number of tickets sold for children be b

The question stated that 272 tickets were sold altogether. So:

\(a + b = 272\)

Now, make sure that only one of the unknown values remain on the left hand side. For example:

\(a = 272 - b\)

I will refer to the above equation as equation 1.

Now, the question also stated that the tickets sold $1694. This means that:

\(7a + 4b = 1694\)

I will refer to this equation as equation 2.

Now, substitute equation 1 into equation 2 by replacing the a in equation 2 with the values on the right hand side in equation 1. For example:

\(7(272 - b) + 4b = 1694\)

Then just solve the equation by finding the value of b.

\(7(272 - b) + 4b = 1694 \\ 1904 - 7b + 4b = 1694 \\ 1904 - 3b = 1694 \\ 1904 - 1694 = 3b \\ 210 = 3b \\ b = 210 \div 3 \\ = 70\)

Lastly, find the value of a. Just take the value of b and then substitute into equation 1.

\(a = 272 - b \\ = 272 - 70 \\ a = 202\)

Yes, they can use the walkie-talkies to talk to each other.

The distance between them is given as 28.2 meters.

The horizontal and vertical distances should be considered when calculating the distance between their apartments using the three-dimensional form of the Pythagorean theorem.

This comes out as \(\sqrt((18^2 + 19^2 + 7^2))\), which equals \(\sqrt(798)\) square root meters, or, to the nearest tenth, 28.2 meters.

Since this distance is less than the 35-meter range of the walkie-talkies, communication should be possible between the two apartments.

The expected gain or loss is an illustration of mean and expected values.

The expected total gain is 83 points

The given parameters are:

The probability of rolling a 6 in a fair die is 1/6.

The probability of not rolling a 6 in a fair die is 5/6.

So, the expected gain in each game is:

\(\mathbf{E(x) = 20 \times \frac 16 - 3 \times \frac 56}\)

\(\mathbf{E(x) = \frac{20}6 - \frac{15}6}\)

Take LCM

\(\mathbf{E(x) = \frac{5}6}\)

\(\mathbf{E(x) = 0.83}\)

The number of games is 100.

So, the expected gain is:

\(\mathbf{Gain = 100 \times 0.83}\)

\(\mathbf{Gain = 83}\)

The income elasticity of demand for tennis balls is -1.5. The negative sign indicates an inverse relationship between income and the quantity demanded of tennis balls, suggesting that tennis balls are an inferior good.

To calculate the income elasticity of demand, we need to use the formula:

Income Elasticity of Demand = Percentage change in quantity demanded / Percentage change in income

Given that incomes increase by 58% and the quantity demanded of tennis balls drops by 87%, we can plug these values into the formula:

Income Elasticity of Demand = (-87%)/58%

Simplifying the calculation:

Income Elasticity of Demand = -1.5

Answer

Ratio of sixth graders who own either a cat or a dog to the total number of sixth graders surveyed given in three ways include

270 : 500

27 : 50

(27/50)

Explanation

Total number of sixth graders surveyed = 500

Number of sixth graders that have been to a baseball game = 375

Number of sixth graders who own either a cat or a dog = 270

Number of sixth graders who have travelled on an airplane = 125

We are then asked to find the ratio of sixth graders who own either a cat or a dog to the total number of sixth graders surveyed.

Ratio of sixth graders who own either a cat or a dog to the total number of sixth graders surveyed

= Number of sixth graders who own either a cat or a dog : Total number of sixth graders surveyed

= 270 : 500

= 27 : 50

Answer: 200 + 4x

Step-by-step explanation:

The required expression is given as 200 + 4x.  

The perimeter is the total length of the boundary of any geometric shape.

It can be calculated by summing all of the external edges of the shape.

The length of each side of square courtyard is given as 50 yards.

After adding x to each side, the new side becomes as 50 + x yards.

The expression for the perimeter of a square is given as below,

Perimeter  = 4 × side

Thus, the expression for the perimeter of new square is 4(50 + x) = 200 + 4x.

Hence, the expression that represents the outside perimeter of the courtyard plus the sidewalk is given as  200 + 4x.

Answer:

x = 12°

Step-by-step explanation:

total interior angle of triangle is 180°

so, 10x -11 + 3x+ 1 + 3x -2 = 180

16x-12 =180

16x = 192

x = 12°

Answer:

x = 88

The measurement of the other unknown angle is = 44°

Step-by-step explanation:

The sum of interior angles in a triangle is equal to 180°

48 + x + x - 44 = 180 add like terms

4 + 2x = 180 subtract 4 from both sides

2x = 176 divide both sides by 2

x = 88

Now to find the measure of two other angles we replace x with 88

Gary will be able to deduct $1,450 in medical expenses on his 2021 tax return.

Based on the information you provided, we can calculate Gary's deductible medical expenses using the following terms:

1. Qualified medical expenses: $5,200
2. AGI (Adjusted Gross Income): $50,000

According to the IRS, taxpayers can deduct qualified medical expenses that exceed 7.5% of their AGI for the tax year 2021. Here's the step-by-step calculation for Gary's deductible medical expenses:

Step 1: Calculate 7.5% of Gary's AGI
7.5% x $50,000 = $3,750

Step 2: Subtract the 7.5% AGI threshold from Gary's qualified medical expenses
$5,200 - $3,750 = $1,450

Gary will be able to deduct $1,450 in medical expenses on his 2021 tax return.

The constant of proportionality from the proportional relationship is 3/2

A proportional relationship is a mathematical relationship between two variables in which their ratio is always equal. In other words, if x and y are in a proportional relationship, then y/x is always equal to a constant value, called the constant of proportionality. This can be expressed mathematically as y = kx, where k is the constant of proportionality and x and y are the variables in the relationship.

To determine the constant of proportionality, we need to use the proportional relationship given.

y = kx

k = constant of proportionality

3/8 = k(1/4)

Solve for k

k = [(3/8) / (1/4)]

k = 3/2

k = 1.5

Step-by-step explanation:

To forecast using data that has seasonality, one commonly used method is seasonal decomposition of time series (STL). This method separates the time series data into three components: trend, seasonality, and residuals. By isolating the seasonal component, you can forecast future values by extrapolating the pattern observed in previous seasons.

Another approach is the use of seasonal autoregressive integrated moving average (SARIMA) models. SARIMA models are an extension of ARIMA models that incorporate seasonal patterns. These models capture both the trend and seasonality in the data and can be used to make forecasts.

To control volatility in various time series models, a common technique is to use a volatility model, such as the generalized autoregressive conditional heteroskedasticity (GARCH) model. This model estimates the volatility of the time series by incorporating past volatility and squared residuals. By modeling and forecasting the volatility, you can better understand and manage the potential fluctuations in the time series data.

A simple moving average method is a technique used to smooth out fluctuations and identify trends in time series data. It involves calculating the average of a fixed number of data points, often referred to as the window size or period. As new data becomes available, the oldest data point in the window is dropped, and the newest data point is included in the calculation. This process is repeated for each subsequent data point. The resulting moving average values can provide insights into the overall trend of the data, helping to identify patterns or changes over time.
