I need to answer things sorry

Answer:

the first answer is correct

the second answer is correct if they messed up on the question and meant to ask for the MAD of set B

I think the 3rd answer is incorrect (I got 1.09), so you might want to double-check your 3rd answer since it is asking for "times bigger", not how much bigger, which means how many times larger is the MAD of set A than that of set B and to find how many times bigger a number is than another number, you have to divide the first number by the second number.

Step-by-step explanation:

Why are quartiles generally more reliable for judging outliers than mean and standard deviation?
lesya [120]
<span>Quartiles are generally more reliable for judging outliers than mean and standard deviations for 2 reasons. The mean is simply the average of all of the numbers, meaning that an outlier can easily be obscured by the masses. Standard deviation is a better method, however only going over by one standard deviation in either direction would also mask an outlier. A strong outlier however will pull a quartile farther in that direction than would normally be expected.</span>

Which of the following is equivalent to
enot [183]

Answer:

Option (2) is correct.

18-\sqrt{-25}=18-5i

Step-by-step explanation:

Given expression 18-\sqrt{-25}

We have to find an equivalence value to the expression.

<u> Radical rule</u>,

\sqrt{-a}=\sqrt{-1} \sqrt{a}

Also,i=\sqrt{-1}

Consider the given expression,

18-\sqrt{-25}

Applying radical rule to \sqrt{-25}

\sqrt{-25}=\sqrt{-1}\sqrt{25}=5i

Thus, the expression becomes,

18-\sqrt{-25}=18-5i

Thus, option (2) is correct.
