A. simpson's paradox

Step-by-step explanation:

The Simpson's paradox was named after Edward Simpson, the person who described this paradox for the first time in 1951. In this paradox, you find two contrary patterns. For example, a positive and a negative correlation, depending on how data is analyzed. The differences in the analyses are how data are grouped. This paradox is observed often in social researches. Most of the times, results are affected by the sample on each group or additional information related to the data.

Write the slope-intercept form of the equation of the line 3x - 2y = -16
denis-greek [22]
We will solve for y.
-3x-16=-2y


Divide both sides by -2
y=\frac{3}{2}x + 8


<u>Slope-intercept form</u>

y=\frac{3}{2}x + 8

Option A. 5/8 is the correct answer.

Step-by-step explanation:

Square root by factorization will be used to solve this question.

Given

\sqrt{\frac{25}{64}}

The square root can be applied to numerator and denominator separately

=\frac{\sqrt{25}}{\sqrt{64}}

Factorization

=\frac{\sqrt{5*5}}{\sqrt{2*2*2*2*2*2}}\\=\frac{\sqrt{5^2}}{\sqrt{2^2*2^2*2^2}}\\=\frac{5}{2*2*2}\\=\frac{5}{8}

Hence,

Option A. 5/8 is the correct answer.

What are the solutions of the following system? y=-2x^2 y=x-2
vovikov84 [41]

Answer:

x = 0.781 , y = -1.219

and

x = -1.281 , y = -3.281.

Step-by-step explanation:

Since both of the x terms are equal to y we can equate the x terms:-

-2x^2 = x - 2

2x^2 + x - 2 = 0

x = [-1 +/- √(1^2 - 4*2*-2) ] / 4

= ( - 1 +/- √(17)) / 4

= 0.781, -1.281.

When x = 0.781  y = 0.781 - 2 = -1.219.

when x = -1.281 , y = -1.281 - 2= -3.281.
