Answer:
A. P(3/4)
Step-by-step explanation:
Answer:
Part 1) The explanatory variable is the type of oven
It is a categorical variable
Part 2) The response variable is the baking time
It is a quantitative variable
part 3) two-sample z-test for proportions should be used for the test
Step-by-step explanation:
An explanatory variable is an independent variable that is not affected by all other variables. In this experiment, the type of oven is the input variable and it is not affected by any other variable
A categorical variable is one that has two or more categories without any intrinsic ordering of the categories. The type of oven is either gas or electric, so it is categorical.
A response variable is a dependent variable whose variation depends on other variables. The baking time in this experiment depends on the type of oven used
A quantitative variable is one that take on numerical values.
A two proportion z-test allows you to compare two proportions to see if they are the same. The null hypothesis (H0) for the test is that the proportions are the same. The alternate hypothesis (H1) is that the proportions are not the same.
ANSWER
She can make 19 batches of oatmeal.
EXPLANATION
First we can change the mixed number into an improper fraction:
In this problem, r = 2/3. The division is:
Using the KFC rule:
Solving we can see that the denominator of the first fraction can be simpliied with the numerator of the second fraction:
Tyra can make 19 batches of oatmeal with 12 2/3 cups of sugar.
Answer: 200
The absolute value of any number is how many spaces away it is from 0 on the number line
(4)3 is also the same thing as 4x3 which is 12n
