(x-1) (x + 2) • 3
factor the polynomial...
Polynomial - an algebraic expression consisting of one or more some terms each term consider consisting of a constant multiple and one or more variables raised to integral powers
Answer:
17
Step-by-step explanation:
since you are subtracting a negative number it reverses, so you actually ADD the two together
so, 12 1/2 + 4 1/2
add the whole numbers first;
12+4=16
then fractions:
1/2 + 1/2= 1
then all together;
16+1=17!
3(2x+5)(2x-5), 5 is the missing term.
Answer:
The <u>sample proportion</u>, denoted by ^p, is given by the formula ^p=
, where x is the number of individuals with a specified characteristic in a sample of n individuals.
Step-by-step explanation:
Sample proportion is used to determine sample mean, sample standard error and test the hypotheses about the population.
<em>sample mean</em> can be stated as p and <em>sample standard error</em> can be found using the equation
where
- p is the sample proportion
And if n×p×(1-p)≥10, then sample is assumed large enough to assume normal distribution and apply statistical test.
