Answer:

The probability that the outcome will be heads = 1/2

Step-by-step explanation:

Sample of Total outcome: HHH THH HHT HTT THH TTH TTH TTT

Possible outcome of heads = more than one head = HHH THH HHT THH

Where H = head, T = tail.

Probability = n(possible outcome)/n(total outcome)

n(possible outcome) = 4

n( total outcome) = 8

Therefore,

Probability = 4/8.

Probability = 1/2

Thus The probability that the outcome will be heads = 1/2

Solve for x in the equation x2-8x+41=0

Alinara [238K]

Answer:

d) 4 ± 5i

Step-by-step explanation:

Here we have to use the quadratic formula.

x = $\frac{-b +/- \sqrt{b^2 - 4ac} }{2a}$

In the given equation x^2 - 8x + 41 = 0, a =1, b = -8 and c = 41

Now plug in the given values in the above formula, we get

x = $\frac{-(-8) +/- \sqrt{(-8)^2 - 4*1*41} }{2*1}$

Simplifying the above, we get

x = $\frac{8 +/- \sqrt{64 - 164} }{2}$

x = $\frac{8 +/- \sqrt{-100} }{2}$

[√-100 = √-1 *√100 = i*10 = 10i] because the value of √-1 = i]

x = (8 ± 10i )/2

Now dividing by 2, we get

x = 4 ± 5i

The answer is d) 4 ± 5i

Hope you will understand the concept.

Thank you.

40 POINTS!!! WILL MAKE BRAINLIEST FOR FIRST ANSWER TO BE CORRECT!

vredina [299]

Answer:

Step-by-step explanation:

We want to basically find all the points at which the line y = 3 intersects the given graph of g(x).

y = 3 is simply a straight horizontal line intersecting the y-axis at (0, 3). If we draw this line, we will see that it intersects g(x) at 3 different points. This indicates that there are 3 values of x where g(x) = 3.

Hope this helps!
