The weighted moving average formula with weights of 0.3 and 0.7 can be calculated using the AVERAGE and SUMPRODUCT functions in Excel. This formula can be used to calculate forecasted values for a range of years.
To use a 2-year weighted moving average to calculate forecasts for the years 1992-2002 with the weight of 0.7 assigned to the most recent year data, we can use the SUMPRODUCT function.
First, we need to create a table that includes the years 1990-2002 and their corresponding data points. Then, we can use the following formula to calculate the weighted moving average:
=(0.3*AVERAGE(B2:B3))+(0.7*B3)
This formula calculates the weighted moving average for each year by taking 30% of the average of the data for the previous two years (B2:B3) and 70% of the data for the most recent year (B3). We can then drag the formula down to calculate the forecasted values for the remaining years.
The SUMPRODUCT function can be used to simplify this calculation. The formula for the weighted moving average using SUMPRODUCT would be:
=SUMPRODUCT(B3:B4,{0.3,0.7})
This formula multiplies the data for the previous two years (B3:B4) by their respective weights (0.3 and 0.7) and then sums the products to calculate the weighted moving average for the most recent year. We can then drag the formula down to calculate the forecasted values for the remaining years.
In summary, the weighted moving average formula with weights of 0.3 and 0.7 can be calculated using the AVERAGE and SUMPRODUCT functions in Excel. This formula can be used to calculate forecasted values for a range of years.

Answer:
answer C: 140 cm
Step-by-step explanation:
If the water rises 14cm in 2 seconds, 21cm in 3 seconds etc... Then the water rises at 7cm per second. Multiply this by 20 seconds and you get 140cm
By find how high the water would be after 20 seconds, you would find out much height is increasing each second.
21 - 4 = 7
28 - 21 = 7
35 - 35 = 7, and so forth.
So, we know that 7 cm is increasing each second. You would just add 7 to the height for each second.
2 --> 14
3 --> 21
4 --> 28
5 --> 35
6 --> 42
7 --> 49
8 --> 56
9 --> 63
10 --> 70
11 --> 77
12 --> 84
13 --> 91
14 --> 98
15 --> 105
16 --> 112
17 --> 119
18 --> 126
19 --> 133
20 --> 140
Thus, after 20 seconds, the water's height would be c) 140 cm.

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels at 80 miles per hour. The westbound train travels at 90 miles per hour. How long will it take for the two trains to be 204 miles apart?
Do not do any rounding.
Answer:
one hour and 12 minutes
Answer:
1 hour and 12 minutes
Step-by-step explanation:
Let's say x = time it takes for the trains to be 204 miles apart.
Speed = Distance/Time,
Time = Distance/Speed,
x = 204/ (80 + 90) = 204/170 = 1 and 1/5 hours or 1 hour and 12 minutes

What is the answer to 3/8 + 2/4
Answer:
1 1/2
Step-by-step explanation:
1.) First find the common denominator of the 2 fractions (8) 4: 4
8: 4, 8
2.) then you write a new expression with the numerator left blank and the denominator as 8 shown below in the step by step explanation. /8 + /8
3.)3/8 + 2/4 multiply by 1 both numerator and denominator for the first fraction. And multiply by 2 both numerator and denominator for the second fraction. 3/8 + 4/8.
4.) Then you add those 2 fractions which I assume you already know how by adding the numerators together, and get 12/8.
5.) You simplify 12/8 and get 1 4/8. 4/8 is equal to 1/2 so its 1 1/2.
A flagpole casts a shadow 16 feet long.
Shanika is standing near the pole. Her
shadow is 4 feet long. Shanika's height is 5
feet. How tall is the flagpole?
Step-by-step explanation:
Since Shanika is standing near the pole, we can safely assume that the triangle formed by Shanika and her shadow is a smaller version of the triangle formed by the pole and its shadow.
By similar triangles:
[tex] \frac{x \: of \: pole}{y \: of \: pole} = \frac{x \: of \: shanika}{y \: of \: shanika} \\ \frac{16}{ height \: of \: pole} = \frac{4}{5} \\ 16(5) = 4 \times height \: of \: pole \\ height \: of \: pole = \frac{80}{4} \\ = 20[/tex]
The height of the pole is 20ft.

How many degrees are on
the interior of a Polygon that
has 18 sides?
Answer:
ask yourself
Step-by-step explanation:
Answer:
160.00° Degrees
Step-by-step explanation:
To find the answer, we have to use the interior angle formula which is
(n-2)*180, where n is the number of sides. This formula gives us the sum of all interior angles in a polygon having ‘n’ sides.
For a polygon with 18 equal sides, first finding the sum of all interior angles of the polygon:-
=(n-2)*180= (18–2)*180=16*180=2880 degree.
We found the sum of all interior angles of 18 sided polygon and it is 2880 degrees.
The polygon we are considering has all sides equal, which means it is a regular polygon. So we can conclude that all of its interior angles are equal.
Sum of all eighteen angles=2880, One angle=2880/18=160 degrees.
Thus, we concluded that the interior angle of the regular eighteen sided polygon
is 160 degrees
Which answer choice correctly identifies the missing information in the problem? Joey and Kirk are in the 6th grade. Kirk is 5 feet 4 inches tall. Joey is 4 feet 8 inches tall. How much taller is Kirk than Joey?
Answer:Kirk is taller than Joey by 8 inches
Step-by-step explanation:
Step 1
Kirk's height is given as =5 feet 4 inches tall.
Joey's height 4 feet 8 inches tall
Difference in height = 5 feet 4 inches
- 4 feet 8 inches
=
Step 2
Bear in mind that 12 inches = 1 feet . Now,8 cannot be subtracted from 4 , so we borrow 1 feet from 5feet, which is equivalent to 12 inches and add to inches so it becomes
4 feet (12+4)inches = 4 feet 16inches
- 4 feet 8 inches - 4 feet 8 inches
= 8 inches
Therefore Kirk is taller than Joey by 8 inches

Your family got a coupon for 35% off at Red Robin. Your bill comes to $45.00 before you use the coupon. Sales tax on the discounted meal is calculated at 8%. You then leave a 15% tip based on the original cost of the meal. How much will dinner and tip cost?
Answer: $38.34
Step-by-step explanation:
Original bill total: $45
35% discount: $15.75
subtotal: $29.25
sales tax: 8% of $29.25: $2.34
bill for meal: $29.25 + $2.34 = $31.59
Tip: 15% of original cost of meal: 15% of $45: $6.75
TOTAL COST: $31.59 + $6.75 = $38.34

A fraction, such as one-half, eight-fifths, or three-quarters, indicates how many components of a particular size there are when stated in ordinary English. An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction.So, (A) fraction of the game Tim wins:
The number of games played is 20.The game won is 16.Then, the fraction will be:
16/204/5(B) Games Tim wins in 30 games.
