Answer:

1/2, 4/3, 1/2, ... any rational number

Step-by-step explanation:

The field of rational numbers is closed under the sum operation. Therefore, if a and b are rational numbers, the number (a + b) is also a rational number.

Consider the rational number a = 1/3, if we add it to any other rational number, the result of that sum will also be a rational number.

Examples:

1/3 + 1/2 = 5/6

1/3 + 4/3 = 5/6

1/3 + 1/6 = 1/2

Answer:

Any rational number

Step-by-step explanation:

A rational number is a number obtained by dividing two integers.

Thus, 1/3 is a rational number.

You can add any rational number to 1/3 and the sum will be a rational number.

Two dice are thrown at the same time. Find the probability of getting

astra-53 [7]

Answer:

(i) = ⅙

(ii) = 1/12

Step-by-step-explaination:

Each dice have 6 number

Then for 2 dice the total number is 12

Now,

(i) the same number on both dice.

Probability (P) = no. of outcome ÷ no. of total outcomes

P = 2 ÷ 12 = ⅙

(ii) different numbers on both dice.

Probability (P) = no. of outcome ÷ no. of total outcomes

P = 1 ÷ 12 = 1/12

Brooke found the equation of the line passing through the points (–7, 25) and (–4, 13) in slope-intercept form as follows.

Arturiano [62]

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

$y = mx + b$

Where:

m: It's the slope

b: It is the cut-off point with the y axis

$m = \frac {y2-y1} {x2-x1}$

We have the following points:

$(x1, y1): (- 7,25)\\(x2, y2): (- 4,13)$

Substituting the values: $m = \frac {13-25} {- 4 - (- 7)} = \frac {-12} {- 4 + 7} = \frac {-12} {3} = - 4$

Thus, the line is of the form:

$y = -4x + b$

We substitute one of the points and find "b":

$13 = -4 (-4) + b\\13 = 16 + b\\b = 13-16 = -3$

Finally we have to:

$y = -4x-3$

Answer:

The equation es $y = -4x-3$
