Answer:
x = 35
105°, 40°, and 35°
Step-by-step explanation:
A triangle has 180°
180° - 40° = 140°
3x + x = 4x
4x = 140
4x /4 = 140 /4
x = 35
------------------
x * 3 = 105°
40°
x = 35°
Answer:
270 people
Step-by-step explanation:
If we think of the ratio as "parts", it becomes very easy!
- 3 parts get their news from Frontbook
- 7 parts get their news from elsewhere
In total there are 3 + 7 = 10 parts
Really, in the town there are 900 people so each part is people
And we know 3 parts get their news from Frontbook, so 3 parts is people
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,
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.
