2x+x+8=3x-2 Is this Infinitely Many Solution One Solution Or No Solution

Mathematics

8 0
<h3>Answer: No Solutions</h3>

The 2x+x on the left side add to 3x

So we have the equation become 3x+8 = 3x-2

Subtract 3x from both sides to get 8 = -2, but that statement is false.

No matter what we replace x with, the original equation will be false.

vichka [17]

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.
