Discrete random variable For first attempt, toss two coins 3 times (just toss it 3 times then list down the result);
For second attempt, toss two coins 3 times (just toss it 3 times then list down the result); and
Observe and explain the results in the first and second attempt

central angle of a triangle has the same measure as its intercepted arc.

step-by-step explanation:

the bolded word " farsighted" could be replaced with visionary.

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5
