Answer:
Step-by-step explanation:
3(x-2)(x-2)-8=5
3[x^2-4x+4]-8-5=0
3x^2-12x+12-13=0
3x^2-12x-1=0
use the quadratic formula to find x { -b+-sqrt(b^2-4ac) } / 2a
where a =3 , b=-12 and c =-1 from our equation above
{ -(-12)+- sqrt[ (-12)^2 - 4(3)(-1) ] } / [2(3)]
{ 12 +- sqrt [ 144 + 12 ] } / 6
{ 12 +- sqrt (156) } / 6
2 +- {sqrt ( 4 *13) } / 6
2 +- { 2 sqrt (13) } /6
2 +- sqrt (13) /3
there you go :)
5/11. the percentage will be:
5/11×100 =500/11
Answer; 45.6
I hoped it helped
Total number of outcomes of 7 from 10 = 10*9*8 / 3*2*1 = 120
probability of each outcoe is 0.85^7* (0.15)^(3) = 0.0010819
Required probability = 120 * 0.0010819 = 0.1298
It is a completely true statement that a <span>degree is larger than 30 arc minutes. The correct option among the two options that are given in the question is the first option. 30 arc minutes is almost equal to 1/2 degree. I hope that this is the answer that you were looking for and the answer has actually come to your great help.</span>
