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

Write a quadratic equation with the given roots. Write the equation in the form ax2 + bx + c = 0 where a, b, and c are integers.
Vikki [24]

A quadratic with roots at 8 and 5 is f(x) = x^2 +12x + 20

In order to find an equation given roots you can create statements that equal 0 in order to create parenthesis. For instance we know x = 8 at one point. So, we can solve that to equal 0.

x = -2 ----> add 2 to both sides

x + 2 = 0

We can do the same for the other zero.

x = -10 ----> add 10 to both sides

x + 10 = 0

Now that we have both of these, we can multiply these two things together. This will give us the function we need.

f(x) = (x + 2)(x + 10)

f(x) = x^2 + 10x + 2x + 20

f(x) = x^2 + 12x + 20
