Answer:
-43
Step-by-step explanation:
f(-3) = 4(-3) - 7 = -12 - 7 = -19
g(4) = -7(4) + 4 = -28 + 4 = -24
-19 + (-24) = -43
Answer:
C. can have more than one factor, each with several treatment groups.
Step-by-step explanation:
A completely randomized design can be used in experimental research of a primary factor or multiple factors. The factors could have several treatment groups which are assigned in a random manner. For example, a researcher, could want to determine the effect of a drug against a disease on a class of people. To do this, he designs a treatment group with different concentrations of the drug and a placebo group. He then gets an equal number of subjects, randomly assigning them to each of the groups. The effect of both treatments are compared to know if the drug is indeed effective against the disease the researcher is experimenting on.
Completely randomized design has found application in agricultural and environmental researches.
Answer:
y = 4
Step-by-step explanation:
Using the altitude- on- hypotenuse theorem
( leg of large Δ )² = ( part of hypotenuse below it ) × ( whole hypotenuse )
y² = 6 × (6 + 2) = 6 × 8 = 48 ( take the square root of both sides )
y = 
= 
= 
× = 4
