**Answer:**

Required probability is 0.19

**Step-by-step explanation:**

The two-way table for the given data is,

Fiction Non-Fiction Total

9th grade 35 8 43

10th grade 52 12 64

Total 87 20 107

It is required to find the probability of the students who prefer to read non-fiction novels, given that they are in 9th grade.

That is, to find the conditional probability .

Now,

So, we get,

<h3>Thus, the required probability is 0.19.</h3>

**Answer:**

**No**.

**Step-by-step explanation:**

A specific real number can never be rational and irrational. Rational numbers can be represented by a fraction a/b ( b not = 0) and where a and b are integers and the fractional is in its simplest form. An irrational number cannot be represented this way.

Let Francis's age be x and Brad's age be 3x

The Product of their ages = 154

So ,

X × 3x = 154

4x = 154

x = 154÷4

x= 36

So Francis age = 36

Brad age = 36×3 = 108

**Answer:**

The sum of the solutions = 1/2

**Step-by-step explanation:**

4m^2 - 2m - 6 = 0

Factor out 2

2( 2m^2 -m-3) =0

2 ( 2m-3)(m+1) =0

Using the zero product property

2m-3 =0 m+1 =0

2m =3 m=-1

m = 3/2 m=-1

Adding the solutions

3/2 -1

+3/2 -2/2

1/2

The temperature is 7 celsius and is also 56 fahrenheit.
