Arte-miy333 [17]
The probability is 2/10 because the only numbers less than 3 from 1-10 is 1 and 2. So it would be 2/10, 20%, or unlikely.

Solve by taking the square root of both sides 3(x-1)^2-162=0
Natali5045456 [20]
We know that: <span>3(x-1)^2-162=0
or (x-1)</span>²= 162:3
and (x-1)²= 54
we <span>take the square root of both sides 
* x-1=</span>√54= 3√6 or x=1+3√6
* x-1= -<span>√54= -3√6 or x=1-3√6
This equation has 2 solutions</span>

Solve the equation on the
Kryger [21]

Answer:

see explanation

Step-by-step explanation:

note that (sinx)² = sin²x

4sin²x - 2 = 0 ( add 2 to both sides )

4sin²x = 2 ( divide both sides by 4 )

sin²x = \frac{2}{4} = \frac{1}{2} ( take square root of both sides )

sinx = ± \sqrt{\frac{1}{2} } = ± \frac{1}{\sqrt{2} }

sinx = \frac{1}{\sqrt{2} } ( sinx > 0 , then x is in 1st/2nd quadrants )

x = \frac{\pi }{4} , π - \frac{\pi }{4} = \frac{3\pi }{4}

sinx = - \frac{1}{\sqrt{2} } ( sinx < 0 , then x is in 3rd/4th quadrants )

x = π + \frac{\pi }{4} = \frac{5\pi }{4} , 2π - \frac{\pi }{4} = \frac{7\pi }{4}

solutions are

\frac{\pi }{4} , \frac{3\pi }{4} , \frac{5\pi }{4} , \frac{7\pi }{4} in the interval [ 0, 2π )
