Answer:

x= 0 and x = -4

Step-by-step explanation:

The first step for absolute value equations is to isolate the expression contained within the absolute value bars:

3|2 x+4|-1 = 11

3|2 x+4| = 12

|2 x+4| = 4

So |2 x+4| is 4 units away from 0 on a number line, but we don't know in which direction -- negative or positive? you'll have two answers.

2 x+4 = 4

AND

2 x+4 = -4

Solve both of those two step equations and you'll get

So 0 and -4 are your solutions

Answer:

When conducting an analysis of variance analysis on a set of samples and the null hypothesis is rejected, we can test for the difference between treatment can be tested with the aid of a t-test. This is employed when 2 related groups are involved. Independent sample, paired sample or one-sample t-test can be conducted.

Step-by-step explanation:

A t-test is a test statistic used to make inferences that determine the differences that exist statistically between 2 related groups. It tells us if the 2 groups tested are from the same population. There are 3 types of t-test namely independent sample t-test, paired-sample t-test and one-sample t-test

Identify the properties of equality needed to isolate a varaible and solve a given equation. Use the drop-down menus to show you
Anna71 [15]

Answer:

If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal. When you solve an equation, you find the value of the variable that makes the equation true. In order to solve the equation, you isolate the variable.
