Question
What is the simplified expression for Negative 3 c d minus d (2 c minus 4) minus 4 d?
a) Negative 5 c d
b) c d minus 8 d
c) 5 c d minus 8 d
d) Negative 5 c d minus 8 d
Answer:
a) Negative 5cd or -5cd
Step-by-step explanation:
The question asks:
What is the simplified expression for Negative 3 c d minus d (2 c minus 4) minus 4 d?
This is expressed mathematically as:
-3cd - d(2c - 4) - 4d
= -3cd -2cd + 4d - 4d
= -5cd + 0
= -5cd
The answer is negative 5cd(in words) or - 5cd
A measure of the variation around the estimate of the mean.
The standard deviation is a statistic that lets you know how tightly all the subjects are clustered around the mean in a set of data. A single standard deviation away from the mean in either of the directions accounts for somewhere around 68 % of data. If two standard deviations are away from the mean, it accounts for around 95% of data. If three standard deviations are away it accounts for 99% of the data.
1) The total range of variation in the dataset is called RANGE.
3) A measure of the variation around the estimate of the mean is SEM (STANDARD ERROR OF THE MEAN).
4) The most common value observed (highest frequency) is MODE.
