Answer:
the answer is (B) this is an example of Simpson paradox.
Step-by-step explanation:
Simpson's paradox is a phenomenon in probability and statistics, in which a trend appears in several different groups of data but disappears or reverses when these groups are combined.
Answer:
b) 2x + y = -4
Step-by-step explanation:
To go from the Point-Slope Formula [y - y₁ = m(x - x)₁] to the Slope-Intercept Formula [y = mx + b], move -1 to the RIGHT side of the equivalence symbol to get this: y = -2x - 4. Although this is a correct answer choice, this is NOT what the question is looking for because you have to go an extra step further, Standard Formula. To go from the Slope-Intercept Formula to the Standard Formula [Ax + By = C], move 2x to the LEFT side of the equivalence symbol, and you will end up with this: 2x + y = -4. So, your answer is b).
Answer:
20 metters long
Step-by-step explanation:
Given:
The measures of the angles in a triangle are in the ratio of 2:2:4.
To find:
The exterior angle that is adjacent to the largest angle.
Solution:
Let the interior angles of the triangle are 2x, 2x and 4x respectively.
According to the angle sum property, the sum of interior angles of a triangle is 180 degrees.
Clearly, x=22.5>1, so 4x is the largest angle between 2x, 2x and 4x.
Now,
Let the required exterior angle that is adjacent to the largest angle be y.
Interior angle and adjacent exterior angles are supplementary, so their sum is 180 degrees.
Therefore, the exterior angle that is adjacent to the largest angle is 90°.
Linear pair and Adjacent angles.
