l satisfaction is highest when couples are newly married, that it decreases during the middle years of marriage, but rises again during later years of marriage. In order to test her hypothesis, she recruits fifty married couples within each of the following conditions: (1) married less than 10 years; (2) married 15-20 years; (3) married more than 25 years. All 150 couples (50 from each condition) complete a standardized measure of marital satisfaction. What is the dependent variable?

Answer:

Marital satisfaction

Step-by-step explanation:

The hypothesis is: marital satisfaction is highest when couples are newly married. In this case, the cause is to be newly married and the effect is marital satisfaction. When you are doing a study with statistics to prove a hypothesis, the cause is the independent variable and the effect is the dependent variable. Then, the dependent variable is marital satisfaction.

Shawn has $5 more than Rj and Riley has $10 less than Shawn. If there combined total is $414, how much does
ExtremeBDS [4]

Answer:

Rj has 138 dollars, Shawn has 143 dollars, and Riley has 133 dollars.

Step-by-step explanation:

Let's make the amount of money Rj has x, so Shawn would have 5+x dollars, and Riley would have (5+x)-10 dollars. Altogether they have 414 dollars, so you can create an equation.

x+(5+x)+((5+x)-10)=414\\3x+0=414\\3x=414\\x=138

Now that we know that x=138, we can substitute x into each equation.

Rj has 138 dollars, Shawn has 143 dollars, and Riley has 133 dollars.
