Yes due to the fact that additive inverse is the oppsite. so she runs up +4 and runs down -4.

Answer:
d) This is a completely randomized design with two explanatory variables (factors).
Step-by-step explanation:
Explanatory variables are independent variables.
In this case, I prepared two explanatory variables, which are : (i)30-second ad
(ii) 60-second ad,
Then, the explanatory variables were assigned to 4 treatment groups, and each variable is done once or thrice.
All subjects are assigned randomly to all treatment groups, with each treatment group seeing one. We can conclude that this is a completely randomized design with two explanatory variables.
Our original equation:

Now, we just solve for k:
When we use PEMDAS, we get this equation:

Now, subtract 248 from both sides:

Now, divide -4 on both sides:

The answer to your problem is
k = 58.5 or k = 117/2. Hope this helps and have a fantastic day!
