Percentage
A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.
Algebraic Expressions
In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.
Numbers
Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.
Subtraction
Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.
Addition
Before we begin to understand the addition of algebraic expressions, we need to list out a few things that form the basis of algebra.
Please answer 2
![1) You measured 0.0899 ± .0008 µg/mL, also with 7 samples [0.092, 0.089, 0.097, 0.808, 0.091, 0.082,
0.095] ± 0.002 µg/mL. Use a t-test to determine if levels have changed with 95% certainty. Note: for equal
size samples with equal uncertainties, you may use the following formula, where n is the number of
samples in one week's data set. The degrees of freedom in this case are 2n-2. You can look up a t-table.
