Answer:
k = 6 : 5 : 4
Step-by-step explanation:
BC : AB : AC = 18 : 15 : 12 = 6 : 5 : 4
EF : DE : DF = 12 : 10 : 8 = 6 : 5 : 4
3(5y + 6) - 4
First, distribute so that it will make the solving easier.
Second, since parentheses indicate multiplication, '3 × 5y = 15y'.
Third, multiply '3 × 6' to get '18'.
Fourth, subtract '18 - 4' to get '14'.

Answer:
C) 15y + 14
Hi I got the answer I will send you soon
Answer / Step-by-step explanation:
To answer this questions, we first try to understand and the basic terms in the narrative. This includes
Response variable: is a variable that measures an outcome or result of a study. In summary, we can say response variable are objects that respond to various changes made during an experimentation process.
Explanatory variable: This is a variable that practically explains the causes of changes in the response variables
So consequentially, if we refer back to the asked question,
EXPLANATORY VARIABLE can be likened to be = Water Temperature
RESPONSE VARIABLE can be likened to be = Weight
Categorical variables places the individuals into a category, while a quantitative variable is a numerical variable.
So consequentially, if we refer back to the asked question,
Water Temperature = Quantitative
Weight = Quantitative
