The quadratic formula works for every quadratic equation, with no exception. Other methods are often tedious and time-consuming, such as completing the square, and others don't work in all situations, such as factoring. Being universal, the quadratic equation becomes an essential tool to solve any quadratic function with little to no thinking, due to the simple solving nature of it.

Use the given data to find the equation of the regression line. Round the final values to three significant digits, if necessary
Y_Kistochka [10]

Answer:

The answer is "choice c".

Step-by-step explanation:

Below, we shall find the line equation, dissociation for both the management's behavior and achievement.

Here, attitudes are the response variable while performance seems to be the predictor as attitude is achievement dependant.

If Y indicates the attitude while X relates to workers' performance.

Let's describe the data like:

y=a+bx+e

Now we get the estimates of e via the least quadratic method, – i.e., by reducing the number of segments.

S=\sum e_{i}^{2}=\sum {(y_{i}-a-bx_{i})^{2}}

minimize S to obtain the estimates of a and b as:

\hat{b}=\frac{\sum{(y_{i}-\bar{y})(x_{i}-\bar{x})}}{\sum{(x_{i}-\bar{x})^{2}}}\\\\\hat{a}=\bar{y}-\hat{b}\bar{x}

So,

a=11.7b=1.02

Equation:

Y=11.7+1.02x
