Answer:

x ≤ -7

Step-by-step explanation

<em>the steps to solve this are:</em>

1. Add 10 to both sides to get the x value and constant isolated on both sides.

-2x ≥ 14

2. Divide both sides by -2 to get the x value

x ≥ -7

3. Flip the inequality sign since you divided by a negative x-value.

x ≤ -7

Hope i could help! :)

Answer:

The Three way mixed ANOVA

Step-by-step explanation:

The Three factor repeated measures ANOVA analysis otherwise referred to as the Three way mixed ANOVA should be used for the analysis.

This is because we are comparing three independent variables in the context.

• People type (statistic lectures and students)

• Imagery type (positive, neutral and negative imagery)

• Repeated measure: Before and After images shown

• Measuring the dependent variable positive arousal as shown in the table attached to the answer.

After going through the table attached you will see that there should be performed a three factor repeated measures ANOVA analysis.

What is the solution to the proportion?<br> 5/x = 2/16

mixas84 [53]

Answer:

I believe the answer is X=40

Step-by-step explanation:

cross multiply 5*16 = X * 2

Multiply 5*16

80= X*2

Add '-2x' to each side of the equation

80 + -2x = 2x + -2x

Combine like terms

80 + -2x = 0

Add '-80' to each side of the equation.

80 + -80 + -2x = 0 + -80

Combine like terms: 80 + -80 = 0

0 + -2x = 0 + -80

-2x = 0 + -80

Combine like terms: 0 + -80 = -80

-2x = -80

Divide each side by '-2'.

x = 40

Simplifying

x = 40

Hope this helped :)
