The simplified expression is: $\mathbf{(i+13)/(170)}$

The fraction is given as:

$\mathbf{(√(-1))/(3 +8i -2 + 5i)}$

Collect like terms

$\mathbf{(√(-1))/(3 +8i -2 + 5i) = (√(-1))/(3 -2+8i + 5i)}$

$\mathbf{(√(-1))/(3 +8i -2 + 5i) = (√(-1))/(1+13i)}$

In complex numbers, we have:

$\mathbf{i =√(-1)}$

So, we have:

$\mathbf{(√(-1))/(3 +8i -2 + 5i) = (i)/(1+13i)}$

Rationalize

$\mathbf{(√(-1))/(3 +8i -2 + 5i) = (i)/(1+13i) * (1-13i)/(1-13i)}$

$\mathbf{(√(-1))/(3 +8i -2 + 5i) = (i(1-13i))/(1^2-(13i)^2)}$

$\mathbf{(√(-1))/(3 +8i -2 + 5i) = (i-13(-1))/(1-169(-1))}$

$\mathbf{(√(-1))/(3 +8i -2 + 5i) = (i+13)/(170)}$

Hence, the simplified expression is: $\mathbf{(i+13)/(170)}$

4. When interpreting a scatterplot, the association must be positive or negative.True
False

Answers

True True True True True True True True

The correct answer is:

True.

Explanation:

An association between two variables in a scatterplot is shown by most of the points following a pattern. This pattern can be linear or non-linear. The more closely the points seem to follow this pattern, the stronger the association.

An association in a scatterplot can be negative, meaning that as one variable increases the other decreases, or positive, meaning that as one variable increases the other increases as well. A negative association will appear to decrease on a graph, and a positive association will appear to increase on a graph.
