Answer:

x = -7.25

Step-by-step explanation:

multiply -4 by 2x + 5 = -8x - 20

-8x -20 -3 = 35

-8x - 23 = 35

-8x = 35 + 23

-8x = 58

x = 58 / -8

x = -7.25

Activating Schema: Draw the figure described below. Then solve for length PR. Right Triangle PQR with the following characterist
Marina CMI [18]

The given triangle is

To solve for PR, we have to use the sine function which is equivalent to the ratio between the opposite leg and the hypothenuse.

\begin{gathered} \sin 52=\frac{PR}{47} \\ PR=47\cdot\sin 52 \\ PR\approx37.04 \end{gathered}<h2>Hence, PR is 37.04 mm long, approximately.</h2>

The least squares regression line minimizes the sum of the:
lorasvet [3.4K]

Answer:

d) Squared differences between actual and predicted Y values.

Step-by-step explanation:

Regression is called "least squares" regression line. The line takes the form = a + b*X where a and b are both constants. Value of Y and X is specific value of independent variable.Such formula could be used to generate values of given value X.

For example,

suppose a = 10 and b = 7. If X is 10, then  predicted value for Y of 45 (from 10 + 5*7). It turns out that with any two variables X and Y. In other words, there exists one formula that will produce the best, or most accurate predictions for Y given X. Any other equation would not fit as well and would predict Y with more error. That equation is called the least squares regression equation.

It minimize the squared difference between actual and predicted value.
