Answer:4\left(1-4r\right)+5\left(r-7\right)=-11r-31
Step-by-step explanation:
An inconsistent system graphs two parallel lines. These parallel lines will never cross. Therefore there are no solutions.
Here, we are concerned about two variables from the above data set, namely, Condo or co-ops and the Unemployment rate. We use the CORREL function of Excel to calculate the correlation coefficient rate and it is = R = -0.01873.
A Weak (negative) correlation exists between the list price of condominiums and co-ops and the unemployment rate.
The correlation coefficient is a statistical measure of the strength of the connection between the relative actions of two variables. The values varied between -1.0 and 1. zero. A calculated wide variety greater than 1. zero or less than -1.zero means that there was an error within the correlation size.
The correlation coefficient is decided with the aid of dividing the covariance by way of the product of the 2 variables' popular deviations.
Correlation values above 0. eight are deemed to signify a strong tremendous linear courting between the variables. Values among zero and 0. three imply a vulnerable relationship or none.
