A number cube is rolled what is the probability that the result is a number greater than five?
ki77a [65]

Answer:

The answer is 1/3

Step-by-step explanation:

Let the events of getting the no. greater than 4 be (>4).

Then,

<em>n</em><em>(</em><em>s</em><em>)</em><em> </em><em>=</em><em> </em><em>6</em>

<em>n</em><em>(</em><em>></em><em>4</em><em>)</em><em> </em><em>=</em><em> </em><em>2</em>

<em>P</em><em>(</em><em>></em><em>4</em><em>)</em><em> </em><em>=</em><em> </em><em>n</em><em>(</em><em>></em><em>4</em><em>)</em><em>/</em><em>n</em><em>(</em><em>s</em><em>)</em>

<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>=</em><em>2</em><em>/</em><em>6</em>

Please help me solve this problem
Karo-lina-s [1.5K]

3.1 a) x = 6 / 5 or x = 2, b) x = - 3 / 2 or x = - 1 / 4, c) x = - 3 or x = 2, d) x = 1 or x = - 2.

3.2 a) x = 9 or x = - 3, b) x = 1 or x = - 1 / 4, c) x = - 3 or x = - 5 d) x = 8 or x = - 18

<h3>How to solve algebraic problems by appying absolute value properties</h3>

In this question we have eight expressions involving <em>absolute value</em> expressions, which can be solved by using the following procedure:

3.1 a) |(1 / 2) · x| = 3 - 2 · x

For x ≥ 0:

(1 / 2) · x = 3 - 2 · x

(5 / 2) · x = 3

x = 6 / 5

For x < 0:

- (1 / 2) · x = 3 - 2 · x

(3 / 2) · x = 3

x = 2

b) |x - 1| = 3 · x + 2

For x ≥ 1:

x - 1 = 3 · x + 2

2 · x = - 3

x = - 3 / 2

For x < 1:

- x + 1 = 3 · x + 2

4 · x = - 1

x = - 1 / 4

c) |5 · x| = x - 12

For x ≥ 0:

5 · x = x - 12

4 · x = - 12

x = - 3

For x < 0:

- 5 · x = x - 12

6 · x = 12

x = 2

d) |7 - x| = 5 · x + 1

For x ≤ 7:

7 - x = 5 · x + 1

6 · x = 6

x = 1

For x > 7:

x - 7 = 5 · x + 1

4 · x = - 8

x = - 2

3.2 a) |9 + x| = 2 · x

For x ≥ - 9:

9 + x = 2 · x

x = 9

For x < 9:

- 9 - x = 2 · x

3 · x = - 9

x = - 3

b) |5 · x| - 3 · x = 2

For x ≥ 0:

|5 · x| = 2 + 3 · x

5 · x = 2 + 3 · x

2 · x = 2

x = 1

For x < 0:

- 5 · x = 2 + 3 · x

- 8 · x = 2

x = - 1 / 4

c) |x + 6| - 9 = 2 · x

For x ≥ - 6:

x + 6 - 9 = 2 · x

x - 3 = 2 · x

x = - 3

For x < - 6:

- x - 6 - 9 = 2  · x

- x - 15 = 2 · x

3 · x = - 15

x = - 5

d) |2 · x - 3| + x = 21

For x ≥ 3 / 2:

2 · x - 3 + x = 21

3 · x = 24

x = 8

For x < 3 / 2:

- 2 · x + 3 + x = 21

- x = 18

x = - 18

Drag each expression to show whether it is equivalent to 36 + 9, 9(4 – 1), or (4 • 9) + (4 • 2).
Natali [406]

Answer:

36x + 9 equivalent to 9(4x + 1)

9(4x - 1) equivalent to (3 . 12x) - (3.3)

(4.9x) + (4 . 2) equivalent to 36x + 8

Hello! please help! will give brainliest to correct answer! will report if you troll... thank you:)​
stich3 [128]
In a coordinate point, the values would go (x,y). Substitute the x and y values from the coordinate points into the equation given.
8(3)+B(4)=40

Multiply 8x3
24+B(4)=40

Subtract 24 from both sides

4B=16

Divide the whole equation by 4

B=4
