What are the solutions of -x^2+4x=x-4
Stolb23 [73]

Answer:

x = -1 and x = 4

Step-by-step explanation:

Step 1:  Get everything to one side of the equation so it's set equal to zero..

-x² + 4x = x - 4  becomes...

  -x² + 3x + 4 = 0        (subtract x and add 4 to both sides)

    x² - 3x - 4 = 0  (divide both sides by -1, we want the x² term to be positive)

   (x - 4)(x + 1) = 0          (factor)

      so

x - 4 = 0,    then x = 4

and

x + 1 = 0,   then x = -1

A new surgery is successful 75% of the time. if the results of 10 such surgeries are randomly sampled, what is the probability t
valentinak56 [21]
\text{Binomial Distribution: } P(X = r) = \binom{n}{r}(p)^{r}(1 - p)^{n - r}
P(X < 9) = 1 - P(X = 9) - P(x = 10)

P(X = 9) = \binom{10}{9}(0.75)^{9}(0.25)
P(X = 10) = \binom{10}{10}(0.75)^{10}

P(X < 9) = 1 - \binom{10}{9}(0.75)^{9}(0.25) - \binom{10}{10}(0.75)^{10}
\approx 0.755974769...
