3 \frac{3}{4} = \frac{15}{4}

Because (4*3) + 3 = 15. Similary find the improper fraction for -2 1/2.

(15/4) / (-5/2) = -3/2

Convert -3/2 into a mixed fraction. 

Therefore, -3/2 = -1 1/2.

Solve for the variable: -(3x)^2 + 3 = -6
Veronika [31]

Hey there! :)


-(3x)² + 3 = -6


Simplify.


-(9x²) + 3 = -6


Simplify.


-9x² + 3 = -6


Subtract 3 from both sides.


-9x² = -6 - 3


Simplify.


-9x² = -9


Divide -9 from both sides.


-9x² ÷ -9 = -9 ÷ -9


Simplify.


x² = 1


So, x = 1 OR x = -1


~Hope I helped!~

pav-90 [236]

Answer:

Step-by-step explanation:

<h3>Mean, Median,mode</h3>

   \boxed{Mean = \dfrac{Sum \ of  \  all \ data}{number \ of data}}

              \sf = \dfrac{234 + 247 + 236+212+248+243+176+195}{8}\\\\= \dfrac{1791}{8}\\\\= 223.875

<h3>Median:</h3>

Arrange the numbers in ascending order.

  176 , 195 , 212 , 234 , 236 , 243 , 247, 248  

Number of data is even. So, median will be the average of 234 and 236

Median = average of the middle two terms.

            \sf = \dfrac{234+236}{2}\\\\ =\dfrac{470}{2}\\\\= 235

Mode is the data which is occurring more number of times.

Range = maximum - minimum

           = 248 - 176

            = 72
