What’s the type of research design to be used in his study?
Vincent conducts a study that will further get to know the frequency of scrub cases between the north and south affiliated hospitals of their school.

A. Descriptive
B. Correlational
C. Causal-Comparative
D. Experimental

A. Descriptive

Step-by-step explanation:

Descriptive design is a type of quantitative research design that tends to describe/depict the current status (condition) of a particular variable or phenomenon. In the case above, the research is quantitative because it deals with quantifiable data, which is the frequency of scrub cases. Vincent was trying to describe the frequency of scrub cases between the north and south affiliated hospitals of their school, which makes it a descriptive design.

A. Descriptive (correct)

B. Correlational (wrong) the research does not compare or find the relationship between any two variables.

C. Causal-Comparative (wrong) no two variables were compared

D. Experimental (wrong) it does not involve experiment.

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
