Not necessarily.
They must decrease together (the question does not say so). Also, the decreases may not be sufficient for the to be correlated. It is less likely that they are negatively correlated, but with the amount of information in the question that is about all that can be said.

What does it mean for variables to show correlation?
A positive correlation coefficient means that as the value of one variable increases, the value of the other variable increases; as one decreases the other decreases. A negative correlation coefficient indicates that as one variable increases, the other decreases, and vice-versa.
What are explanatory variables in regression?
Explanatory (or independent) variables are variables such that changes in their value are thought to cause changes in the "dependent" variables.
How do the y value change as the x value increase if the line is a negative slope?
the Y value decreases.
What happens to the fraction as the denominator decreases?
The value of the fraction increases.
Can Km be a negative value?
No the Km can never be a negative value. The Km increases or decreases with temperature. An incorrect calculation can produce a negative value.
What does it mean for economic variables to positively related?
if two variables are positively related,it means that the two variables change in the same direction.that is,if the value of one of the variables increases,the value of the other variable too will increase.for example,if employment as an economic variable increases in a country,and price of goods too increases then we can say that these two variables(employment and price) are positively related
Is women's intelligence proportional to the length of her skirt?
Skirt lengths and intelligence are randomly correlated having a correlation coefficient of zero to plus 0.15 ie knowing the measure of one does not predict the value of the other--they are independent variables. To say such and such are not correlated is to say you have not compared the variables. They may have identity with a value of plus one, or they may be inversely related having a value of negative one, or they may be randomly correlated with a value of zero--but to compare is to correlate.
What does a correlation -0.9 mean?
The two variables involved are highly but not perfectly correlated. When the value of one of them rises the other falls, and vice versa.
If two variables have a direct relationship what happens to the value of one as the value of the other changes?
In a direct relationship, as one variable increases, the other variable also increases. Conversely, as one variable decreases, the other variable decreases as well. The relationship between the two variables is positive and proportional.
What does it mean for variables to show correlation?
A positive correlation coefficient means that as the value of one variable increases, the value of the other variable increases; as one decreases the other decreases. A negative correlation coefficient indicates that as one variable increases, the other decreases, and vice-versa.
The present value of a perpetuity decreases when what decreases?
When the value of money decreases (inflation)
What is an inverse proportion relationship?
An inverse proportion between two variables is when the value of one variable increases, the other decreases. Mathematically, this is shown as: x = k / yn where x and y are the two variables, and k and n are constants.
What are continuous and discrete variables?
the value of variables is determined by the equation, discrete variables have absolute single value while the continuos have a range value
Is eliminating variables from equations equal to find the value of the variables?
No, but eliminating variables is one of several ways to find the value of variables in a system of equations.
What value of x when y200?
You need to give context for an answer. How are x and y correlated?
What are independent variables and dependent variables in math?
Independent variables are the input value of a function (usually x) and dependent variables are the output value of the function (usually y).
What are explanatory variables in regression?
Explanatory (or independent) variables are variables such that changes in their value are thought to cause changes in the "dependent" variables.
