Answer:

0.19+0.46i and 0.19-0.46i

Step-by-step explanation:

\neq (-b+\sqrt{b^2-4ac} )/2a\\and\\(-b-\sqrt{b^2-4ac} )/2a\\\\a=8\\b=3\\c=2\\(-3+\sqrt{3^2-4*8*2} )/(2*8)\\= - 0.1875+0.463512i\\(-3-\sqrt{3^2-4*8*2} )/(2*8) = -0.1875-0.463512i

hope its right

<h3>What is probability?</h3>

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.

Mr. Larsen's third-grade class has 22 students, 12 girls, and 10 boys.

Two students must be selected at random to be in the fall play.

Then the probability of no boys being chosen will be

Total event = ²²C₂ = 231

Favorable event = ¹²C₂ = 66

Then the probability will be

P = 66 / 231

P = 0.2857

P ≅ 0.29

A window shaped like a parallelogram has an area of 23 4/5 square feet. The height of the window is 2 4/5 feet. How long is the
USPshnik [31]

Answer:

base = 8\frac{1}{2}ft

Step-by-step explanation:

The general formula for the area of a parallelogram is:

A = bh, where b = the length of the base and h = the height

Using the given values for area and height, we can solve for the missing variable of 'b':

23\frac{4}{5}=\frac{119}{5}

2\frac{4}{5}=\frac{14}{5}

\frac{119}{5}=\frac{14}{5}h

Multiply both sides by the reciprocal:

(\frac{5}{14})(\frac{119}{5})=(\frac{14}{5})(\frac{5}{14})h

\frac{119}{14}=h

h=8\frac{1}{2}ft
