The formula used for moving average is
a1= 1/4 ( W1+W2+W3+W4)
a2= 1/4 ( W2+W3+W4+ W5)
a3= 1/4( W3+W4+ W5+W6)
and so on
Where W1= week 1, W2= week 2 ,W3= week3
a1= 1st average , a2= 2nd average
The similar process is used for five year moving average
a1= 1/5 ( W1+W2+W3+W4)
a2= 1/5 ( W2+W3+W4+ W5)
a3= 1/5( W3+W4+ W5+W6)
Only it is divided by 5 instead of 4
To calculate the four-week and five-week moving averages, we need to sum up the sales for the specified number of weeks and divide by the corresponding period.
Week | Sales | 4-Period Moving Average | 5-Period Moving Average
-----|-------|------------------------|------------------------
1 | 17 | |
2 | 21 | |
3 | 19 | |
4 | 23 | |
5 | 18 | 20.00 |
6 | 16 | 19.25 |
7 | 20 | 19.50 |
8 | 18 | 19.25 |
9 | 22 | 19.00 |
10 | 20 | 19.00 |
11 | 15 | 18.75 | 19.20
12 | 22 | 18.75 | 19.20
13 | 22 | 19.75 | 19.40
14 | | 19.75 | 19.40
15 | | 19.75 | 19.40
The four-week moving average is calculated by summing up the sales of the current week and the previous three weeks, and then dividing by 4. The five-week moving average is calculated similarly, but with a period of five weeks.
A flying squirrel's nest is 12 feet high in a tree. From its nest, the flying squirrel glides 13 feet to reach an acorn
that is on the ground. How far is the acorn from the base of the tree? Draw a picture and show your work.
Answer: the answer should be 5
if you draw a right triangle 12 would be the line that goes up (A) and 13 would be the slanted line (C) so that leaves the bottom line to be C.
hope this helps!
Step-by-step explanation:
[tex]A^{2} +B^{2} =C^{2} \\12^{2} +B^{2} =13^{2} \\144+B^{2} =169\\-144 -144\\\sqrt{B^{2} } =\sqrt{25} \\ B=5[/tex]

The things which are necessary to know in order to solve problems involving quadratic regression are data, correlation coefficient and quadratic equation.
What is quadratic regression?The quadratic regression is the statistical process which is used to obtain the equation of parabola, to represent the data set in the most appropriate way.
The things which are necessary to know in order to solve problems involving quadratic regression are listed below.
The most important thing for approaching quadratic regression problem is visualize the data.Make a proper table with x and y values with the data. These values should form a parabola for the quadratic regression.Find the correlation coefficient. The closer the value of correlation coefficient to 1, the data good fit into the quadratic equation.Least square method is the best way to solve the problems involving quadratic regression.Thus, the things which are necessary to know in order to solve problems involving quadratic regression are data, correlation coefficient and quadratic equation.

There are 40 people in a choir.

Work out the value of n.
You must show how you get your answer.
n =
9514 1404 393
Answer:
n = 4
Step-by-step explanation:
Of the 40 people, half are women, so there are 20 women.
There are 5 times as many women as men, so 20/5 = 4 are men.
The remainder are children, so there are 20-4 = 16 children.
The ratio of children to men is ...
children : men = 16 : 4 = 4 : 1 = n : 1 . . . . . . . . remove a factor of 4 from 16:4
The value of n is 4.
If 70% of a number is 42 and 15% of the same number is 9, find 85% of that number.
Answer: 51
Step-by-step explanation:
let x be the number.
(70%)x = 42
0.7 x = 42
x = 60
we check 15% x 60 = 0.15 x 60 = 9, which is true.
85% of that number = 85% x 60 = 0.85 x 60 = 51.

Can somebody please tell me the answers? This is due today and I’m stuck. Thanks!
answers / step-by-step explanation:
every single one of these equations false
3² = 2 * 2 * 2
is false since three multiplied by itself equals to 9 and 2 multiplied by itself 3 times equals to 8 and as you can see, they are not the same numbers
9 > 8
5^(3)=15
is also false since 5^(3) equals to 125 and 15 do not equal to each other since they are not the same number
125 > 15
8^(1 )=7^(1)
is the easiest one because it is basically just asking if 8 = 7 and to answer that question, it doesn't
8 > 7

Two trains on opposite tracks leave the same station at the same time. One train travels at an average speed of 80 kilometres per hour and the other travels at an average speed of 70 kilometres per hour. How long after they leave the station will they be 50 km apart?
9514 1404 393
Answer:
20 minutes
Step-by-step explanation:
The trains are separating at the rate of 80 +70 = 150 km/hour. The time required to be 50 km apart is then ...
time = distance/speed = (50 km)/(150 km/h) = 1/3 h = 20 minutes
