Answer:
x² + 6x + 5 = 0
Step-by-step explanation:
Given
x² + 6x + 8 = 3 ( subtract 3 from both sides )
x² + 6x + 5 = 0 ← in standard form
Answer:
D is the correct representation.
=
Step-by-step explanation:
Here, the given equation is:
here, numerator =
and denominator =
Solving numerator and denominator separately, we get
NUMERATOR:
Denominator:
Hence, the transformed fraction is:
or, implied fraction is
Hence, D is the correct representation.
Using the concept of standard deviation, it is found that the standard deviation of the data-set will remain the same.
-----------------------------------
- The mean of a data-set is given by the <u>sum of it's observations, divided by the number of observations</u>.
- The standard deviation is given by the <u>square root of the sum of the differences squared of each observation and the mean, divided by the one less than the number of values</u>.
- If all observations are increased by a value x, the mean will also increase by x.
- In the standard deviation, at the sum of the differences squared of each observation and the mean, each observation is increased by x, as is the mean, thus, the sum stays the same, while the standard deviation also stays the same.
