3.1 Solve<span> : </span>4x2<span>+3 = 0. Subtract 3 from both sides of the equation : </span><span>4x2 = -3</span>. Divide both sides of the equation by 4: x2<span> = -3</span>/4 = -0.750. When two things are equal, their square roots are equal. Taking the square root of the two sides of the equation we get: x = ± √ -3/4. In Math, i is called the imaginary unit. It satisfies i 2<span> =-1.</span>
Answer:
Step-by-step explanation:
(5 - 9)/2= -4/2= -2 the midpoint
For this problem, we use the repeated trials equation:
P = n!/r!(n-r)!*p^(n-r)*q^r
where
P is the total probability of having r successful trials out of the total n trials. p is equal to 13/58, while q is equal to 1 - 13/58.
P = 4!/4!(4-4)!*(13/58)^(4-4)*(1 - 13/58)^4
P = 0.362 or 36.2%
5:9 (perimeter is just the sum of all the side lengths)
