Say a certain manufacturing industry has 63.1 thousand jobs in 2008, but is expected to decline at an average annual rate of 1.7
kenny6666 [7]
If the industry is losing 1.7 thousands jobs in one year, in 10 years it will then lose 1.7*10, or 17 thousand jobs.

now, if we take 63.1 to be the 100%, how much is 17 in percentage off of it?

\bf \begin{array}{ccllll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
63.1&100\\
17&x
\end{array}\implies \cfrac{63.1}{17}=\cfrac{100}{x}

solve for "x", round it up, make it negative, since it should be a negative rate, since is a decrease in the initial amount.

Does this data appear to be proportional? Explain why or why not.
Artist 52 [7]

The given data is proportional because, we get 3.15 when Quantity y is divided by Quantity x, y/x = 3.15

Given,

The data;-

Quantity x; 2 , 6 , 9 , 5 , 1

Quantity y; 6.3, 18.9, 28.35, 15.75, 3.15

We have to find the proportionality between the data set given;-

Lets see the proportionality;-

Quantity y ÷ Quantity x

6.3 ÷ 2 = 3.15

18.9 ÷ 6 = 3.15

28.35 ÷ 9 = 3.15

15.75 ÷ 5 = 3.15

3.15 ÷ 1 = 3.15

Here,
