What is the 3 period moving average forecast for week 6?
Answers
7000 is the 3 period moving average forecast for week 6.
What is average forecast?Using a moving average, a data set's general trend may be determined. The sales volume from the company's historical data is the data set used in operations management. For predicting recent trends, this method is quite helpful. Simply said, it is the average across a range of times.
The most basic method for predicting is a simple moving average (SMA). The data from the previous 'n' periods are added up, and the sum is divided by 'n' to create a simple moving average. So the projection for the following period is based on the moving average value.
3-period weighted moving forecast for week 6:
= (Demand for Period 3 + Demand for Period 4 + Demand for Period 5) / 3 = (8000 + 7000 + 6000) / 3
= 7000
3-period weighted moving forecast for week 6 = 7000

What is the standard form of (2,7) ; m =-4 ??
-Exploring Linear Equations in Two Variables
Answers
Answer:
4x + y = 15
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = - 4 , then
y = - 4x + c ← is the partial equation
to find c substitute (2, 7 ) into the partial equation
7 = - 4(2) + c = - 8 + c ( add 8 to both sides )
15 = c
y = - 4x + 15
the equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
then
y = - 4x + 15 ( add 4x to both sides )
4x + y = 15 ← in standard form
For the vectors u = (-4,-1) and v= (1,3), express u as the sum u=p+n, where p is parallel to v and n is orthogonal to v. + 7 21 33 11 u=p+n= 10 10 10 10
Answers
For the given vectors the sum of u is (-44/10,-6/10).
Vectors are mathematical objects that have both magnitude and direction.
The projection of u onto v is equal to the dot product of u and the unit vector of v divided by the magnitude of v.
The unit vector of v can be found by dividing v by its magnitude. Once we have the unit vector, we can multiply it by the dot product and add it to the initial point of v to find p.
Since u = (-4,-1) and v = (1,3), the magnitude of v is √(1^2 + 3^2) = √10 and the unit vector of v is (1/√10, 3/√10).
The dot product of u and the unit vector of v is
=> (-4)(1/√10) + (-1)(3/√10)
=> -4/√10 - 3/√10.
Thus,
=> p = (-4/√10 - 3/√10)(1/√10, 3/√10) + (1,3)
=> p = (-4/10 - 3/10, -1/10 + 3/10) + (1,3)
=> p = (7/10 + 3/10, 2/10 + 3/10) = (10/10, 5/10).
To find n vector, we subtract p from u.
Finally,
=> n = u - p = (-4,-1) - (10/10, 5/10)
=> (-4 - 10/10, -1 - 5/10) = (-44/10,-6/10).

find the area of the region that is bounded above by the curve f(x)=(x 8)2 and the line g(x)=−x−2 and bounded below by the x-axis.
Answers
The area of the region bounded by f(x)=(x-8)^2, g(x)=-x-2 and the x-axis is the definite integral of f(x)-g(x) from -2 to 8.
The area of the region bounded by f(x)=(x-8)^2, g(x)=-x-2 and the x-axis is given by the definite integral of f(x)-g(x) from -2 to 8. First, expand f(x) and g(x) to get f(x)=x^2-16x+64 and g(x)=-x-2. Then, subtract g(x) from f(x) to get f(x)-g(x)=x^2-16x+66. This is the equation of the area of the region. To calculate the area, use the definite integral of f(x)-g(x) from -2 to 8. This is equivalent to the integral from -2 to 8 of x^2-16x+66 dx. After integrating, the area is given by the expression (x^3/3)-8x^2+66x from -2 to 8, which is equal to 1176/3 units^2. Therefore, the area of the region bounded by f(x), g(x) and the x-axis is 1176/3 units^2.

Answers
Answer:
If the pet store had 1/9 of a bag of cat food, and they want to divide it equally between 4 cats, then each cat would get 1/9 of the bag divided by 4.
So, each cat would get:
1/9 ÷ 4 = 1/9 * 1/4 = 1/36
So, each cat would get 1/36 of the bag of cat food.

How can the pans of pasta now be sliced so that both pans have the same-sized pieces? If Nelda has served 5 pieces from 1 pan so far, what fraction of 1 pan has she served?
Answers
The pans must be sliced in the following way:
Slice the first pan in 10 slices.Slice the second pan in 4 slices.B) 5 pieces are equivalent to the fraction 1/8 of the pan.
How can the pans of pasta now be sliced so that both pans have the same-sized pieces?The number of pieces in each pan will be equal to the product between the numbers of slices (assuming that the sets of slices are perpendicular)
So, if she wants to have pieces of the same size, she needs to:
Slice the first pan in 10 slices.
Slice the second pan in 4 slices.
Now both of these will have:
10*4 = 40 pieces.

Answers
The radius of the circle with the same vertex is 6 and the height of the triangle is 10.39 and the area of the triangle is 62.34.
Since the arc divides the triangle into two regions of equal area, it follows that half of the circle's area is equal to the area of the triangle. The area of a triangle with sides 12 and 12√3 and a 60-degree angle can be found using the formula for the area of a triangle, which is 0.5bh.
The height of the triangle can be found using trigonometry, as the sine of 60 degrees is 0.8660. Thus, the height of the triangle is 10.39 and the area of the triangle is 62.34.
Since half of the circle's area is equal to the area of the triangle, the radius of the circle can be found by taking the square root of the area of the triangle and dividing it by pi. Thus, the radius of the circle is 6.

it costs johnny $15 a month plus $1.50 per song to download music. this situation is represented by the expression 1.5x 15, where x is the number of songs downloaded. how much will it cost johnny to download 10 songs?
Answers
The cost of downloading 10 songs for Johnny is $30.
The cost of downloading music for Johnny can be represented by the expression 1.5x + 15, where x is the number of songs downloaded. To find the cost of downloading 10 songs, we can plug in x = 10 into the expression:
1.5 * 10 + 15 = 15 + 15 = 30
So, it will cost Johnny $30 to download 10 songs. This expression represents the total cost as the sum of a $30 $30 ($15 monthly fee) and a variable cost ($1.50 per song fee).
The fixed cost remains constant regardless of the number of songs downloaded, while the variable cost increases as more songs are downloaded.

The imperial gallon (imp gal), defined as 4.54609 litres, which is or was used in the United Kingdom, Ireland, Canada, Australia, New Zealand and some Caribbean countries.
The US gallon (US gal), defined as 3.785411784 L, (231 cubic inches) which is used in the US and some latin American and Caribbean countries.
The US dry gallon ("usdrygal"), defined as 1/8 US bushel (exactly 4.4.0388377086 L)
By using the above formula to convert US gallons to litres.
Solution: Inserting the value of a gallon in the above formula we will get:

Amana could buy more than ___ inches but less than ___ inches of purple wire.
Answers
Amanda could buy more than 4 inches but less than 8 inches of purple wire to make triangle.
For Amanda to make a triangle, the sum of the lengths of any two sides must be greater than the length of the third side.
Therefore, the minimum amount of purple wire she could buy would be the sum of the lengths of the blue and green wires (4 inches + 8 inches = 12 inches), minus the length of the longest side (which is 8 inches), so 12 inches - 8 inches = 4 inches.
The maximum amount of purple wire she could buy would be the sum of the lengths of the two shorter sides (4 inches + 4 inches = 8 inches).
