BabaBlast [244]3 years ago

Answer:

x = i\sqrt{55} , -i\sqrt{55}

Step-by-step explanation:

x^2 + 8^2 = 9

Simplify the 8^2

x^2 + 64 = 9

Subtract 64 from both sides

x^2 = -55

Take the square root from both sides

x = +/- \sqrt{-55}

Simplify

x = i\sqrt{55} , -i\sqrt{55}

Hope this helps!

Answer:

the first option

Step-by-step explanation:

variability !

what does that word tell us ?

it means that there are more individuals differences.

you could also use "accuracy" as the opposite - we are aiming for the mean value ...

imagine some bow and arrow tournament.

who wins ?

the person with the highest accuracy across all the attempts (and that means the lowest variability in the results across all attempts relatively to the target center representing the predefined mean value).

now look at the graphic for neighborhood A.

and then for neighborhood B.

which one has the data points more clustered around the center (where the mean value is going to be) ? this one has lower variability than the one where the data points are having more than one cluster or are even all over the place.

remember, for the variability you have to add all the differences to the mean value. the smaller the differences to the mean value, the smaller the variability.

in neighborhood B almost all data points have a larger difference to the mean value.

so, the variability will be higher here.

(08.03)Consider the following set of equations:
Furkat [3]

Answer:

  Infinite solutions

Step-by-step explanation:

Equation M is equation P multiplied by 3. The equations are dependent, so any solution of one of them is also a solution of the other. There are an infinite number of (x, y) pairs that will satisfy either (both) equation(s).
