Answer:
B
Step-by-step explanation:
In that scenario, you would have one T and two H's, in any order. Looking at the chart, this happens in 3 different scenarios. Since there are a total of 8 possible outcomes, the probability of this happening is 3/8 or answer choice B. Hope this helps!
It’s 1, anything to the zero power is one.
<u>Answer:</u>
55
<u>Step-by-step explanation:</u>
Just multiply then divide:
55 x 32 = 1760
1760 ÷ 32 = 55
Or just easier like:
55 x 32 ÷ 32 = 55

You put the equation in slope-intercept form by solving for y.
.. 7y = -6x -42 . . . . . .subtract 6x
.. y = (-6/7)x -6 . . . . . divide by 7
Compare this to the pattern
.. y = mx +b
The slope is the coefficient of x, m = -6/7.
The intercept is the constant term, b = -6.
![D=b^2-4ac\\D=4^2-4(4)(1)\\D=16-16\\D=0](https://tex.z-dn.net/?f=D%3Db%5E2-4ac%5C%5CD%3D4%5E2-4%284%29%281%29%5C%5CD%3D16-16%5C%5CD%3D0)
Meaning there's only 1 real root, complete the square and you get the answer.
![(x+y)^2=x^2+2xy+y^2](https://tex.z-dn.net/?f=%28x%2By%29%5E2%3Dx%5E2%2B2xy%2By%5E2)
We're going to use this formula, so if x² = 4x² then x = 2x
and if y² = 1 then y = 1
Straight to formula
![(2x+1)^2=0\\x=-\frac{1}{2}](https://tex.z-dn.net/?f=%282x%2B1%29%5E2%3D0%5C%5Cx%3D-%5Cfrac%7B1%7D%7B2%7D)
Because (2x+1)² is basically (2x+1)(2x+1), we get the same value of x.
So the answer is x = -1/2
(When D>0, there are 2 real roots.)
(When D=0, there are only 1 real root.)
(When D<0, there are no real roots, but 2 complex roots.)
