Answer:28inches & 84inches
First, lets write an equation that fits the data given. The string is 112 inches long. When the two pieces are cut, the first piece will be three times as long as the second piece. If we use the variable, x, to represent the second piece, we can create the following equation...
112=3x+x
Now lets solve for x.
112=4x
divide both sides by 4
28 inches=x
Now we know that the second piece is 28inches long. Since the first piece is three times as long, simply multiply 28*3 and we'll know the length of the first piece.
28*3=84 inches
28+84=112
Time series patterns that repeat themselves after a period of days or weeks are called Seasonality
A time series is a collection of observations of well-defined data items obtained through repeated measurements over time.
Seasonality is the presence of variations that occur at specific regular intervals less than a year, such as weekly, monthly, or quarterly
The term cycle refers to the recurrent variations in time series that in generally last longer than a year and it can be as many as 15 or 20 years.
Here, the time series patterns that repeat themselves after a period of days or weeks.
So that is called seasonality
Hence, time series patterns that repeat themselves after a period of days or weeks is called seasonality

Answer:
25% ?
Step-by-step explanation:
i think it's 25 because i counted up the dots and so theres 20 of them
then i counted the dots over the 1 child thing and there was 5
so i divided 5 by 20 and 0.25
then turned it into a percentage
and got 25%
i hope this helps
Answer:
12.5 feet
Step-by-step explanation:
Answer:
db / dt = kb
this becomes b(t) = Ce^(kt)
C = 100, the initial population
P(1) = 420 = 100 e^(1k)
4.2 = e^k
ln 4.2 = k
a) thus, b(t) = 100 e^(t ln 4.2)
b) b(3) = 100 e^(3 ln 4.2)
c) growth constant will still be ln 4.2 (constant percentage of populatioin)
d) 10000 = 100 e^(t ln 4.2)
100 = e^(t ln 4.2)
ln 100 = t ln 4.2
t = ln 100 / ln 4.2
