What are the odd of rolling two number cubes and getting the sum of 7

1 answer:

8 0

Number of possible outcomes of one cube = 6
Number of possible outcomes of the other cube = 6 
Number of possible outcomes of two cubes = 6 x 6 = 36 

Number of ways to roll a sum of 7 with two cubes = 6 

1 - 6 
2 - 5 
3 - 4 
4 - 3 
5 - 2 
6 - 1

[7.07] Choose the correct product of (6x + 2)2.

Archy [21]

The correct product of (6x+2)2 = 36x2 + 24x + 4
This is how to get this:
The equation is (a+b)2 = (a+b) (a+b). So, when you apply this to your equation, you get this:
(6x+2)2 = (6x+2) (6x+2) = 36x2 + 12x + 12x + 4 = 36x2 + 24x + 4

A number divided by three less two is at most two

Marina CMI [18]

x ≤ 12

Solution:

Let us take the number be x.

A number : x

A number divided by three : $$\frac{x}{3}$

A number divided by three less two : $$\frac{x}{3}-2$

A number divided by three less two is at most two : $$\frac{x}{3}-2\leq 2$

Now, simplify the inequality,

$$\Rightarrow\frac{x}{3}-2\leq 2$

Add 2 on both sides of the inequality,

$$\Rightarrow\frac{x}{3}-2+2\leq 2+2$

$$\Rightarrow\frac{x}{3}\leq 4$

Multiply by 3 on both sides of the equation,

$$\Rightarrow\frac{x}{3}\times3\leq 4\times3$

$$\Rightarrow x\leq 12$

Hence x ≤ 12.
