"Turn the two numbers into a fraction; place the number you want to turn into a percentage over the whole value. Convert the fraction into a decimal. Multiply the decimal by 100 to get the percent."
By selecting a regression specification based on R2 a, a researcher implicitly adopts which of the following principles explain as little of the variation in y using as many xi as possible.
<h3>What does R² value tells you?</h3>
R² value provides an estimate of the relationship between the motion of the dependent variable, which depends on the movement of the independent variable in the equation.
The linear regression equation can be given as,
![Y=b_o+b_1X](https://tex.z-dn.net/?f=Y%3Db_o%2Bb_1X)
Here, Y is dependent variable and X is independent variable. Using the regression equation, it is see that how much Y value changes when we change the value of X.
Variation is the distribution of the value of Y, which is little for the different xi possible.
Thus, by selecting a regression specification based on R2 a, a researcher implicitly adopts which of the following principles explain as little of the variation in y using as many xi as possible.

Answer:
The inequality in this case is 100 + 400*t > 500 + 350*t and for B to be cheaper Sophia has to rent it for more than 8 months.
Step-by-step explanation:
In order to write the inequality we first need to write two equations one for each apartment. For apartment A we have a fixed cost of $100 and a variable cost of $400 that varies according to the time living in there, so we have:
rent = 100 + 400*t
For apartment B we have a fixed cost of $500 and a variable cost of $350 that varies according to the time living in there, so we have:
rent = 500 + 350*t
In order for the total paid in B to be less than for the one in A we need to satisfy the following inequality:
100 + 400*t > 500 + 350*t
400*t - 350*t > 500 - 100
50*t > 400
t > 400/50
t > 8 months
The inequality in this case is 100 + 400*t > 500 + 350*t and for B to be cheaper Sophia has to rent it for more than 8 months.
<span>Rigid motion of a plane is a transformation where the original and new image are congruent. In short, it's also known as isometry.
In the case above, ΔDWP is presumed to be congruent to </span><span>ΔMJS. Rigid motions involved here are translation and rotation.
In translation, you are basically sliding/moving the figure. </span>ΔDWP is moved five (5) units down then one (1) unit to the left. Thereby, coinciding point W of ΔDWP and point J of ΔMJS.<span>
Next rigid motion used is rotation. The figure is simply rotated approximately 90 degrees thereby coinciding all points of </span>ΔDWP to ΔMJS<span>.
To check for congruency by just merely looking on the plane, compare the lengths of the sides of the triangles.
side DW = side MJ = 2 units
side WP = side JS = 4 units
side PD = side SM = 5 units
Therefore, we can say that </span>ΔDWP is congruent to ΔMJS.<span>
