**Answer:**

**2.25 or 2 1/4 hours**

**Step-by-step explanation:**

To answer this, we simply have to divide the number of hours spent studying by the number of days before the test. And since 6 3/4 is in fraction form, we will convert to decimal because it makes it easier to multiply that way:

6.75 ÷ 3 = 2.25

So, Andrea studied for **2.25 or 2 1/4 hours each day before her test**

Hope this helps :)

**Answer: In math, especially when learning algebra and geometry, you are more likely to a lot of deductive reasoning. That is the process of using theorems, properties of numbers and other recognized rules and procedures to solve equations, to prove geometrical constructions, congruence of angles, etc. Deductive reasoning is the foundation of most of that kind of math, so it is more important when learning and applying the principles and theorems.**

**Inductive reasoning involves taking specific observations and known facts and using them to make predictions and generalizations. You are more likely to use inductive reasoning when working with statistics and probability. **

**So both are important at some point, but it may be more important to learn deductive reasoning at first.**

**Step-by-step explanation:**

**The question is not properly formatted (see attachment for the frequency table and the options)**

**Required**

The conditional relative frequency table by column

**We have:**

To get the conditional frequency by column, we simply divide each cell by the corresponding total value (on the last row)

**So, we have:**
