Solve Let's solve your equation step-by-step.5+3.9x−8.15x25x=0
Step 1: Simplify both sides of the equation.−0.326x2+3.9x+5=0
Step 2: Use quadratic formula with a=-0.326, b=3.9, c=5.x=−b±sqrt(b2−4ac)2ax=−(3.9)±sqrt((3.9)2−4(−0.326)(5))2(−0.326)x=−3.9±sqrt(21.73)−0.652x=−1.1680135096973403,13.131203693746418Answer:<span>x=

Answer:
so the probability of selected student is in the drama club is 1/5
Step-by-step explanation:
total students = 40
drama club= 8
art club= 12
we have to find probability of drama club
P (drama) = favorable outcome / total outcome
= 8 / 40
= 1/ 5
so the probability of selected student is in the drama club is 1/5
