The forecasts for September sales volume using a linear trend equation, a five-month moving average, exponential smoothing with a smoothing constant of 0.40, the naive approach, and a weighted average are 17.86, 18.60, 18.72, 21.00, and 19.60 thousands, respectively.

1. A linear trend equation:

This is a method of extrapolating future values from existing data by fitting a linear line to the data points by calculating the slope and y-intercept of the line. To calculate the trend equation, we use the formula Yt = mXt + b, where Yt is the forecasted value, m is the slope of the line, Xt is the independent variable, and b is the intercept. We can calculate m and b by using the formula m = (n∑XY - (∑X)(∑Y)) / (n∑X2 - (∑X)2) and b = (∑Y - m(∑X)) / n. To calculate the forecast for September, we substitute the September value with the 7th month value and solve the equation. Y7 = mX7 + b. Therefore, the forecast for September is 17.86 thousands.

2. A five-month moving average:

This is a method of smoothing data points by taking the average of the preceding five data points and using this average value as the forecast. To calculate the five-month moving average, we use the formula Yt = (Yt-1 + Yt-2 + Yt-3 + Yt-4 + Yt-5) / 5. Therefore, the forecast for September is 18.60 thousands.

3. Exponential smoothing with a smoothing constant equal to .40, assuming a March forecast of 19(000):

This is a method of forecasting future values by using a weighted average of the past data points and the previous forecast. To calculate the forecast, we use the formula Yt = αYt-1 + (1-α)Ft-1, where Yt is the forecasted value, α is the smoothing constant, Yt-1 is the previous data point, and Ft-1 is the previous forecast. Therefore, the forecast for September is 18.72 thousands.

4. The naive approach:

This is a method of forecasting future values by simply taking the most recent data point as the forecast. Therefore, the forecast for September is 21.00 thousands.

5. A weighted average using .50 for August, .20 for July, and .30 for June:

This is a method of forecasting future values by taking a weighted average of the past data points. To calculate the forecast, we use the formula Yt = (0.5Yt-1 + 0.2Yt-2 + 0.3Yt-3) / (0.5 + 0.2 + 0.3). Therefore, the forecast for September is 19.60 thousands.

The forecasts for September sales volume using a linear trend equation, a five-month moving average, exponential smoothing with a smoothing constant of 0.40, the naive approach, and a weighted average are 17.86, 18.60, 18.72, 21.00, and 19.60 thousands, respectively.

The total number of adult tickets sold is 65  and student ticket is 45 .

An equation is a mathematical statement formed when two algebraic expression are equated by an equal sign.

It is given that

Elisa sold 110 tickets for the football game

Adult tickets cost $2.50

student tickets cost $1.10.

Total amount collected $212

Let x be the total number of adults ticket sold

Let y be the total number of student tickets sold

then the equation that can be formed using the given data is

x + y = 110

2.5 x + 1.1 y = 212

Solving the equation using Elimination method

2.5 y - 1.1 y = 275 - 212

1.4 y = 63

y = 45

Substituting y = 45 to get x

x = 65

Therefore , the total number of adult tickets sold is 65  and student ticket is 45 .

Answer:

The lengths of the sides are 12cm, 28cm and 36cm.

Step-by-step explanation:

Let the smallest side be 4x, the middle side be 7x and the largest side be 9x.

Smallest side + middle side + largest side = 60cm

4x + 7x + 9x = 60

20x = 60

x = 60 ÷ 20

x = 3

Smallest side (4x) = 3 × 4

                             = 12

Middle side (7x)  = 7 × 4

                           = 28

Largest side (9x) = 9 × 4

Answer:

1 Hour = 17 miles

2 Hours = 34 miles

3 Hours = 51 miles

4 Hours = 68 miles

5 Hours = 85 miles

Step-by-step explanation:

Every half hour is 8.5 miles, so for every hour you multiply 8.5 by a factor of 2. So 1 hour would be 8.5 x 2, 2 hours would be 8.5 x 4, and so on.

The solution of the square root equation is x = 8

A square root is a number such that when multiplied by itself, it gives another number.

The square root of a number x is given by √x

Given the square root equation above, we have that

√(x - 4) = - 2

To solve this equation, first, we remove the square root by squaring both sides of the equation. So, we have that

√(x - 4) = - 2

√(x - 4)² = (- 2)²

x - 4 = 4

Adding the number 4 to both sides of the equation, we have that

x - 4 + 4 = 4 + 4

x + 0 = 8

x = 8

So, the solution of the equation is x = 8

a) 77    b)B

Step-by-step explanation:

letterF is the same as 77 meaning that X will be the same as letterF cause the are vertically opposite angles.

I just did the question on math watch.

The measure of the angle ∠BFH that is 'x' will be 77 degrees. Then the correct option is B.

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360 °.

Alternate angle - If two lines are parallel then the third line will make z -an angle and z-angles equal angles with the parallel lines.

Line AD is parallel to line EH. And the line CG is the transversal line to line AD and EH.

The angle ∠FAB is congruent with the angle ∠BFH. Because they are alternate angles. Then we have

∠BFH = ∠FAB

x = 77°

The measure of the angle ∠BFH that is 'x' will be 77 degrees. Then the correct option is B.

Distributive Property

Step-by-step explanation:

Distributive Property would have to be used here as the 3z would have to be multiplied with each of the values in the bracket for a simplified expression. This is as follows:

3z(2x+7y-5)

= 6xz + 21zy - 15z

Hence, 6xz + 21zy - 15z is the simplified expression.

Be sure to mark this as brainliest! (I am one brainliest away from Genius). Thanks!

The property that we would use to simplify the expression 3z(2x + 7y - 5) is the distributive property.

From the question, we have the following parameters that can be used in our computation:

3z(2x + 7y - 5)

The distributive property states that when we multiply a number or variable by a sum of terms in parentheses, we can distribute the multiplication to each term inside the parentheses.

In this case, we can distribute the 3z to each term inside the parentheses:

3z(2x + 7y - 5) = 6zx + 21zy - 15z

So using the distributive property, we have simplified the expression by multiplying 3z to each term inside the parentheses.

Rounding to nearest hundredth basically means to round to 2 decimal places.

Now, we look at the 3rd digit after decimal.

If that's 5 or more, we notch up the 2nd digit by 1.

If that's less than 5, we notch it down by 1.

Third digit is 8, so we notch up the 2nd digit (1) by 1 , so we have 1 becomes 2.

Step-by-step explanation:

The sorter's error is 91 seconds. This means that the sorter miscalculated the time it would take for the water bottle to travel the length of the belt by 91 seconds.

When anything is referred to as being "long," it refers to its overall length. In other words, it is the larger of the third or upper two dimensions of a geometric object. An example of a shape with two dimensions is a rectangle.

To find out how many seconds it takes for the water bottle to travel the length of the belt, we can use the equation:

distance = rate x time

We know the distance (294 feet) and the rate (7 feet per 6 seconds). Let's solve for time:

294 feet = (7 feet/6 seconds) x time

294 feet x 6 seconds = 7 feet x time

1764 seconds = 7 feet x time

time = 1764 seconds / 7 feet

time = 252 seconds

So it takes 252 seconds for the water bottle to travel the length of the belt.

Now let's calculate the sorter's error:

343 seconds - 252 seconds = 91 seconds

The sorter's error is 91 seconds. This means that the sorter miscalculated the time it would take for the water bottle to travel the length of the belt by 91 seconds.

Answer:

1) x = -6, 8

2) x = -1 + i√2

Step-by-step explanation:

1)

\( {x}^{2} - 2x - 48 = 0\)

\((x - 8)(x + 6) = 0\)

x = -6, 8

2)

\(3 {x}^{2} + 2x + 1 = 0\)

x = (-2 + √(2^2 - 4(3)(1))) / (2 × 1)

x = (-2 + √(4-12)) / 2

x = (-2 + √-8) / 2

x = (-2 + 2i√2) / 2
