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.
Answer:
a = 180 - b - c
Step-by-step explanation:
To solve for a variable, move all the terms to the other side except a. You move terms across an equal sign using inverses.
So subtract b and c to the other side.
For this case we have the following expression:
We eliminate the parentheses taking into account that:
We add similar terms:
Different signs are subtracted and the sign of the major is placed:
Finally, the expression is reduced to:
Answer:
Option B
Answer:
Step-by-step explanation:
We want to find the solution to the equation:
Rearrange:
Combine like terms:
We can add five to both sides:
And divide both sides by five. Therefore:
The Missing side of the right triangle is 10
