Answer:

A value, or values, we can put in place of a variable (such as x) that makes the equation true.

Example: x + 2 = 7

When we put 5 in place of x we get: 5 + 2 = 7

5 + 2 = 7 is true, so x = 5 is a solution

Б) 3х2 – 10 = 152<br>how to solve with square root

Tju [1.3M]

Answer:

$3\sqrt{6}$ and $-3\sqrt{6}$

Step-by-step explanation:

We will take numbers to one side and variables to one side eliminate the "Square" with "Square Root" and solve for the variable x. The process is shown below:

$3x^2-10=152\\3x^2=152+10\\3x^2=162\\x^2=\frac{162}{3}\\x^2=54\\x=\sqrt{54}$

Now, we need to reduce the radical by using the rule shown below:

$\sqrt{x*y}=\sqrt{x} \sqrt{y}$

Now,

$\sqrt{54}=\sqrt{6*9} =\sqrt{6} \sqrt{9} =3\sqrt{6}$

The correct answer is $3\sqrt{6}$ and $-3\sqrt{6}$

<u>Note:</u> squaring positive and negative makes the same answer

A die is thrown 100 times and a ‘6’ occurs on 32 occasions. Based upon this information find the probability of getting a ‘6’ wh

Morgarella [4.7K]

in every die thrown 100 times a six occurs 32 times

so the probability of obtaining a die after 100 throws = $\frac{32}{100}$
