What is the solution of the following equation 2x^2-3x+2=0

zaharov [31]

Answer:

$x= \frac{3+\sqrt{7}i}{4}}$ or $x=\frac{3-\sqrt{7}i}{4}}$

Step-by-step explanation:

$2x^2-3x+2=0$

We complete the square as follows

Group the constant term on the right hand side

$2x^2-3x=-2$

Divide through by 2,

$x^2-\frac{3}{2}x=-1$

Add half the square of the coefficient of x to get;

$x^2-\frac{3}{2}x+(-\frac{3}{4})^2=-1+(-\frac{3}{4})^2$

Simplify to get

$(x-\frac{3}{4})^2=-1+\frac{9}{16}$

$(x-\frac{3}{4})^2=-\frac{7}{16}$

Take the square root of both sides to get

$(x-\frac{3}{4})=\pm \sqrt{-\frac{7}{16}}$

Solve for x

$(x-\frac{3}{4})=\pm \frac{\sqrt{7}i}{4}}$

$x=\frac{3}{4} \pm \frac{\sqrt{7}i}{4}}$

$x= \frac{3+\sqrt{7}i}{4}}$ or $x=\frac{3-\sqrt{7}i}{4}}$

A telephone service representative believes that the proportion of customers completely satisfied with their local telephone ser

Delvig [45]

Answer:

(0.1361 ; 0.2239)

Step-by-step explanation:

n1 = 1400 ; p1 = 0.50 ; n2 = 1320 ; p2 = 0.38

Confidence interval = mean ± margin of error

Mean = p1 - p2

Point estimate :

p1 - p2 = 0.50 - 0.38 = 0.18

Margin of Error (MOE) = Zcritical * S. E

Standard Error(S. E) :

Sqrt[(p1(1-p1)/n1) + (p2(1-p2)/n2)]

(p1(1-p1)/n1) = 0.50(0.50) / 1400 = 0.0001785

(p2(1-p2)/n2) = 0.38(0.62) / 1320 = 0.0001784

S. E = sqrt(0.0001785 + 0.0001784)

S. E = sqrt(0.0003569)

S. E = 0.0188917

Zcritical at 98% = 2.326

MOE = Zcritical * S. E

MOE = 2.326 * 0.0188917

MOE = 0.0439420942

MOE = 0.0439

Confidence interval = mean ± margin of error

Confidence interval = 0.18 ± 0.0439

Lower boundary = (0.18 - 0.0439) = 0.1361

Upper boundary = (0.18 + 0.0439) = 0.2239

(0.1361 ; 0.2239)

Answer:

SAS

Step-by-step explanation:

Sides WV and XV on either side of angle WVX have been shown to be congruent to their corresponding parts. When you're concerned with a Side, Angle, and Side in that geometrical sequence, the SAS theorem is applicable.
