Answer:

Step-by-step explanation:
We are given 2 fractions.
1st fraction is Negative StartFraction 3 over 8
i.e.

2nd fraction is negative one-fourth
i.e.

We have to find the quotient when 1st fraction is divided by 2nd fraction.
<u>Definition</u> of quotient is given as:
Quotient is the result obtained when one number is divided by other number.

is converted to
and the 2nd fraction is reversed i.e.
if the fraction is
it becomes
and the sign
is changed to
.
Solving above:

So, the quotient is
.
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:
8:30
Step-by-step explanation:
well it's a delay so you will have to add
6:30 + 2 = 8:30
Calculate The mode of this set of numbers 2,5,1,6,3,8,5,9,2,4,7
koban [17]
The mode is 5 & 2 because they both appear the most and the same amount of times that’s why they’re both the mode.
