Answer:

x=1

Step-by-step explanation:

First we make our equation. Half the books so 1/2 and then 1/3 and 4. So first off they are all postive ( we cant have negative books) and to make the equation we need to find how many books are all together. So 1/2+1/3+4. First combine like terms 1/2+1/3=3/4 then add 3/4 to 4 which is the same as 3/4+4/1= 4 3/4.

<em>Let's solve your equation step-by-step.</em>

mafiozo [28]

Answer:

A) zero; cannot

Step-by-step explanation:

In line with the principle of rational expectations, expectation errors are unpredictable. The expectations of all available information will not differ from the optimal projections.The word optimal projection is inexorably intertwined with the best guess in rational expectations theory.

A local running group collected data on the number of miles its group members run each week, x, and their average mile time, y.
ratelena [41]

Answer:

The correlation coefficient of the data is -0.13, which means as the weekly mileage increases, it has no effect on the average mile time.Step-by-step explanation:

The correlation coefficient of a data set describes how closely related two variables are. Correlation coefficients close to positive 1 show a strong positive correlation, while correlation coefficients close to negative 1 show a strong negative correlation. When a correlation coefficient is close to 0, it shows no correlation between the data.

For the given data set, calculate the correlation coefficient using technology.

This r-value is closer to 0 then it is to -1. Thus, the correlation coefficient of the data is -0.13, which means as the weekly mileage increases, it has no effect on the average mile time.
