Answer: Correlation

Step-by-step explanation:

The statistics that should be used to determine if scores on these two surveys are related to each other is referred to as correlation.

Correlation indicates the degree by which the variables that are given are linearly related. Correlation is used in the testing and determination of the strength of association that can be found between two variables.

In this case, since the student wants to determine if degree of introversion or extroversion s associated satisfaction with life, the correlation will be appropriate to use.

The ideal mechanical advantage of a slope is given by the ratio between the output load, which is simply the weight of the object (), and the input force  applied to move the object along the slope:

The energy conservation law states that the potential energy of the object when it reaches the final height h is equal to the work done to move the object along the distance of the slope , i.e.

From this we find

Therefore, we can substitute this into the formula of the ideal mechanical advantage and calculate its value:

What is the solution of the linear-quadratic system of equations? { y = x 2 + 5 x − 3 y − x = 2
photoshop1234 [79]

Try substituting those values, and you will see they do not fit either equation.

looking at the 2nd equation, y = x+2, so

x+2 = x^2+5x-3

x^2 + 4x - 5 = 0

(x+5)(x-1) = 0

x = -5 or 1

so, y = -3 or 3

the solutions are thus (-5,-3)(1,3)

Hope this helps

But if you add $300 to 9.5% you get 328.5 US$
