Answer:
Option B,
Step-by-step explanation:
<u>Step 1: Sort the data set from least to greatest</u>
{5, 4, 2, 7, 2, 6, 16}
{2, 2, 4, 5, 6, 7, 16}
<u>Step 2: Determine the median</u>
The median of a data set is the middle of the data set. In this example, we have 7 numbers which means that the 4th number on the sorted data set would be the median. This data set has 5 as the 4th number so that is our answer.
Answer: Option B,
Answer:
Step-by-step explanation:
The lines surrounding 10 are called positive brackets, meaning the no matter what number is in those brackets, it will always come out of positive.
There is nothing to do with just 10 because we don't need to change anything.
|10| simplified is 10
Answer:
x = i and x = i
Step-by-step explanation:
Given
+ 6x² + 5 = 0
Using the substitution u = x², then
u² + 6u + 5 = 0 ← in standard form
(u + 1)(u + 5) = 0 ← in factored form
Equate each factor to zero and solve for u
u + 1 = 0 ⇒ u = - 1
u + 5 = 0 ⇒ u = - 5
Convert solutions back into terms of x
x² = - 1 ⇒ x = = i
x² = - 5 ⇒ x = = i
