What’s the probability?

Mathematics
1 answer:
son4ous [18]2 years ago
6 0

Answer:

\frac{1}{8}

Step-by-step explanation:

The probability for a flip on either side of the coin is always 50% or \frac{1}{2}

So to get the probability for the three flips just do:

(\frac{1}{2}) ^{3}  or \frac{1}{2} × \frac{1}{2} × \frac{1}{2}

Either way you solve it the answer is \frac{1}{8}

The measure of angle F is 130 degrees.
Vitek1552 [10]
130 degrees is the total degrees of the angle,
So if part of that angle was 70 degrees with a missing part you can just subtract to find the missing angle.
(130-70=60)
The missing angle equals 60 degrees

Plz i need help and plz explain
Montano1993 [528]

\frac{ {x}^{2}  - 7x + 12}{ {x}^{2} - x - 12 }  \\  =  \frac{ {x}^{2} - 4x - 3x + 12 }{ {x}^{2} - 4x + 3x - 12 }  \\  =  \frac{x(x - 4) - 3(x - 4)}{x(x - 4) + 3(x - 4)}  \\  =  \frac{(x - 3)(x - 4)}{(x + 3)(x - 4)}  \\  =  \frac{x - 3}{x + 3}

x² - x - 12 ≠ 0

x² - 4x + 3x - 12 ≠ 0

x (x - 4) + 3 (x - 4) ≠ 0

(x + 3)(x - 4) ≠ 0

x ≠ -3 or x ≠ 4

(B)

a family is building a rectangular fountain in the backyard. the yard is rectangular and measures 8x by 9x. The fountain is goin
densk [106]
Teachers often all this problem a donut problem because it’s like the donut hole getting cut out of the middle. The way that you solve this is to find the area of the whole yard and subtract the area of the fountain. Since they are rectangles we’re going to use A = LW
Area of yard - Area of fountain
A = (8x)(9x) - (2x)(5x)
A = 72 x^2. - 10 x^2
A 62 x^2
