Answer:
Consumption of moderate doses of St. John's Wort
Step-by-step explanation:
A variable that changes without depending on the other variable is called the independent variable and the variable that changes relative to the independent variable is called the dependent variable.
Here the effect of St. John's Wort on memory is being studied.
So, the independent variable would be the consumption of moderate doses of St. John's Wort and the dependent variable would be the effect it has on the person's memory.
A. This is an example of a situation making use of the concept of Fundamental Principles of Counting. On the first spot, Sam may choose from the five available flags. On the next spot, he can only choose from four flags. This goes on until no more flag is left. For short, there are 5! ways. This is equal to 120.
b. Since only 3 out of the five flags can be used and the arrangement is important, make use of Permutation. The answer is 5P3 = 60. There are 60 ways.
Answer:
0.08
Step-by-step explanation:
Answer:
a. x = 7; b. 75
Step-by-step explanation:
Equilateral means all sides equal the same measurement
4x - 3 = 2x + 11
4x - 2x = 11 + 3
2x = 14
x = 7
Plug in x = 7 to any equation
4(7) - 3
28 - 3
25
Perimeter means add up all 3 sides
25 + 25 + 25
75
