A roulette wheel has 37 numbers (0 through 36).
NeX [460]

\large\boxed{\frac{1}{1369}}

We'll assume that there is an equal probability of any position on the wheel, so a \frac{1}{37} chance for any given number.

We must take the probability of getting a 27, then the probability of getting a 15, and multiply them together to find the chances that they both happen in a row.

\frac{1}{37}\cdot\frac{1}{37}=\boxed{\frac{1}{1369}}

Graphing exponential functions and then State the domain, range and asymptote​
Luda [366]

9514 1404 393

Answer:

  D: all real numbers

  R: f(x) > 0

  A: f(x) = 0

  (-∞, 0), (+∞, +∞)

  vertical stretch by a factor of 2; left shift 2 units

Step-by-step explanation:

The transformation ...

  g(x) = a·f(b(x -c)) +d

does the following:

  • vertical stretch by a factor of 'a'
  • horizontal compression by a factor of 'b'
  • translation right by 'c' units
  • translation up by 'd' units

For many functions, horizontal coordinate changes are indistinguishable from vertical coordinate changes. Exponential functions tend to be one of those.

__

Using the above notation, you seem to have f(x) = 3^x, and g(x) = 2f(x+2). The transformation is a vertical stretch by a factor of 2, and a translation left 2 units.

__

As with all exponential functions, ...

  • the domain is "all real numbers"
  • the range is all numbers above the asymptote: f(x) > 0
  • the horizontal asymptote is f(x) = 0

The function is a growth function, so ...

  • x → -∞, f(x) → 0
  • x → ∞, f(x) → ∞

_____

<em>Additional comment</em>

The left shift is equivalent to an additional vertical stretch. The function could be rewritten as ...

  f(x) = 18(3^x)

with no left shift and a vertical stretch by a factor of 18 instead of 2.

Is 7(x+2y) the equivalent of 14x + 14y
ryzh [129]

Answer:

the expressions are not equivalent

Step-by-step explanation:

7(x+2y)    (distribute 7 into the parentheses)

= x(7) + 2y(7)

= (7x + 14y)  ≠ (14x + 14y)

hence the expressions are not equivalent
