The 3-year Weighted Moving Average (WMA) for predicting the amount of sports equipment sales in 2022 is 1.7.

A Weighted Moving Average gives more weight to recent data and less weight to historical data. This is accomplished by multiplying the price of each bar by a weighting factor. WMA will track prices more precisely than a related Simple Moving Average due to its unique formula. A Weighted Moving Average (WMA) is a sort of moving average that prioritizes recent data over historical data. A moving average is a technical indicator that displays how the price has moved on average over a given time period.

Here,

weights=0.5, 0.3, and 0.2

(0.5×1+0.3×2+0.2×3) / (0.5+0.3+0.2) = 1.7

First he goes from home to the video store.

home (-2,3) --> video store (4,3)

There is no change in his y distance, so the distance he travels is only the change in x.

distance from home to video store = 4 - (-2) = 6 units

Then he goes from the video store to the grocery store

video store (4,3) --> grocery store (4,-4)

There is no change in his x distance, so the distance he travels is only the change in y.

distance from video store to the grocery store = 3 - (-4) = 7 units

Then he goes from the grocery store to the fast snacks

grocery store (4,-4) --> fast snacks (-2,-4)

There is no change in his y distance, so the distance he travels is only the change in x.

distance from the grocery store to the fast snacks = 4 - (-2) = 6 units

Finally he goes from the fast snack store to his house

fast snacks (2,-4) --> house (2,3)

There is no change in his x distance, so the distance he travels is only the change in y.

distance from the fast snacks to his house = 3 - (-4) = 7 units

therefore the total distance he traveled is 6 units + 7 units + 7 units + 6 units = 26 units

On solving the provided question we can say that he probability of getting the following result using the binomial probability formula and the normal curve approximation is P(4, 16, 1/2) = 0.0280.

Probability is the possibility or chance that something will happen. Probability = how many different paths there are to success/the total number of events that might occur. A coin flip, for instance, has a 50% chance of coming up heads since there is only one method to acquire a head and there are a total of two possible outcomes (a head or tail).

Percent, A relative value that specifies one hundredth of an arbitrary amount. A percentage (representing 1%) is 1 in 100. So 100% represents the whole and 200% represents double the amount.

For example, 1 percent of 1,000 chickens is 1/100 of 1,000 or 10 chickens. 20% of the crowd is 20/100 1,000 or 200.

For the given case:

Original cost of each game = $30.50

75% of $30.50

(75/100) × 30.50

= $22.875

The cost of second game = 30.50 - 22.875

= $7.625

Since, 4 games are bought at once; this means 2 set of games with one on original price and another on discount price each.

Total cost of four games:

2 games at original price = 2 × 30.5

Function composition is an operation о used in mathematics that takes two functions, f and g, and creates a function, h = g о f, such that h(x) = g. The function g is applied in this operation to the outcome of applying the function f to x.

Given:

u(x) = x^2 + 3

w(x) = √x+2

We have to find (w о u)(2) and (u о w)(2).

First to find (w о u)(x)

(w о u) = w(u(x))

           = w(x^2 + 3)

(w о u) = √(x^2 + 3) + 2

⇒ (w о u)(2) = √(2^2 + 3) + 2

   (w о u)(2) = √7 + 2

Now to find (u о w).

(u о w)(x) = u(w(x))

= u(√x+2)

= (√x+2)^2 + 3

= x + 4√x + 4 + 3

(u о w)(x) = x +  4√x + 7

⇒ (u о w)(2)  = 2 + 4√2 + 7

   (u о w)(2)  = 9 + 4√2

Answer:

Step-by-step explanation:

You want to know the least-cost path of a pipeline from 3 km offshore to 4 km east of the closest point on shore. The cost of pipe in the water is $0.5M/km, and onshore is $0.3M/km.

The solution in the general case for this kind of question is that the sine of the angle between the route directly to shore and the least-cost route is the ratio of the onshore cost to the in-water cost.

  sin(α) = (0.3M/km)/(0.5M/km) = 3/5

The distance from the closest point onshore (E) to the least-cost onshore point is the product of the distance from shore and the tangent of this angle:

  distance downshore = (3 km)·tan(arccos(3/5)) = 2.25 km

Since the refinery is 4 km downshore, this point is 1.75 km from the refinery.

The pipe should follow a direct path underwater from the well to a point 1.75 km west of the refinery, then downshore the remaining 1.75 km to the refinery.

If x represents the distance from the refinery to the point where the pipeline comes ashore, the cost of the route in millions will be ...

  c = 0.5√(3² +(4-x)²) +0.3x

where the square root function is calculating the underwater length of the pipeline using the Pythagorean theorem.

This cost function will be minimized when its derivative with respect to x is zero.

  c' = 0.5(1/2)(2x -8)/√(x² -8x +25) +0.3 = 0

  0 = 0.5(x -4) +0.3√(x² -8x +25) . . . . . . numerator of the combined terms

  4 -x = 0.6√(x² -8x +25) . . . . multiply by 2, add 4-x

  16 -8x +x² = 0.36x² -2.88x +9 . . . . . . square both sides

  0.64x² -5.12x +7 = 0 . . . . . subtract the right side

  x = (5.12 -√(5.12² -4(0.64)(7)))/(2(0.64)) = 2.24/1.28 = 1.75

The route with lowest cost comes ashore 1.75 km from the refinery.

__

Additional comment

The cost of the pipeline will be ...

  c = 0.5√(9 +(4-1.75)²) +0.3(1.75) = 0.5√14.0625 +0.525

  c = 2.4 . . . . million dollars

The attached graph shows the cost function has a minimum of 2.4M at a distance of 1.75 km from the refinery. The cost is only 2.5M if the pipe runs directly from the well to the refinery (x=0).

A permutation is an arrangement of a set of items in a specific order. Permutations are typically denoted using the notation "P" followed by the number of items being permuted and the number of items being chosen at a time.

The formula for calculating permutations is as follows:

where:

P(n,r) is the number of permutations of r items from a set of n items.

n! is the factorial of n, which is the product of all positive integers less than or equal to n.

The number of terms of the Maclaurin series for eˣ that should be used to estimate [tex]e^{0.1}[/tex] to within 0.00001 is 4.

Taylor’s inequality:

If Rn( x ) = 0

Rn(x)=0

Rn​(x)=0.

The given function is eˣ

Thus, all the derivatives of eˣ is eˣ itself.

Suppose that, the nth derivative of eˣ is eˣ

To estimate the value of [tex]e^{0.1}[/tex] substitute the value of x as 0.1.

Note that Taylor series is called Maclaurin series when a=0.

Usually, Maclaurin series will starts with n=2.

Increase the value of n until the reminder is less than 0.00001.

By Taylor’s inequality,

If | [tex]f^{n}[/tex](0.1) | = [tex]e^{0.1}[/tex]≤ M then | Rₙ(x) |≤[tex]\frac{M}{(n+1)!}[/tex] [tex]|0.1-0|^{n+1}[/tex]

Substitute the value of n as 2. Then,

[tex]|R2(x)|[/tex]≤[tex]\frac{M}{(2+1)!} |0.1-0|^{2+1}[/tex]

≤ [tex]\frac{e^{0.1}}{3!} |0.1|^{3}[/tex]

≤ [tex]\frac{e^{0.1}}{6} 0.001[/tex]

≤ 0.00018

Since [tex]|R2(x)|[/tex] ≥ choose the value of n as 3. Then,

[tex]|R3(x)|[/tex] ≤[tex]\frac{M}{(3+1)!} |0.1-0|^{3+1}[/tex]

≤ [tex]\frac{e^{0.1}}{4!} |0.1|^{4}[/tex]

≤ [tex]\frac{e^{0.1}}{24} 0.0001[/tex]

≤ 0.0000046

Therefore, [tex]|R3(x)|[/tex] ≤ 0.00001

That is, n=3 satisfies the inequality.

So, by adding the 4 terms (when n=0,1,2,and 3) of the Maclaurin series, it

is possible to estimate the value of [tex]e^{0.1}[/tex] to within 0.00001.

Thus, the number of terms of the Maclaurin series for eˣ that should be used to estimate [tex]e^{0.1}[/tex] to within 0.00001 is 4.
