Answer:
Question 3: B
Question 4: A, D, E
Step-by-step explanation:
Polynomials can not have a variable appear in the denominator.
4b^4-9b+2, 2x+7, and x-3 are in standard form.
Answer:
1. single sample design
2. matched pairs
3. two independent samples.
Step-by-step explanation:
the response variable is known as the dependent variable, it is the variable that the researcher is interested i finding. the response variable is the x variable that responds to changes in the independent variable.
1.
In this question the researcher has only one sample that is the specimen. that is the reference specimen that she obtained. Therefore it is a single sample design.
the response variable here is the measurement of concentration.
2. In this question we have two pairs, men and women. The researcher is interested in comparing attitudes as she interviews them. so response variable is attitude or behavior
3. this is a 2 independent sample design. The researcher is using two different methods to test and their average is being compared.
Calculate out how many times the denominator goes into the numerator. To do that, divide 234 by 8 and keep only what is to the left of the decimal point:
Answer:
The temperature in Minneapolis was -9°F. The next day, the temperature was warmer than -9°F.
let increased temperature be x
temperature of next day = -9°f +x
Answer:
