What is the solution to the equation sqrt8x= sqrt4+2x

Mathematics
1 answer:
sp2606 [1]3 years ago
3 0

I'm going to make some assumptions here:

That your sqrt8x= sqrt4+2x means √(8x) = √(4+2x). (There are other interpretations.)


Squaring both sides, 8x = 4 + 2x, or 6x = 4, or x = 4/6, or x = 2/3.

Suppose that the probability of getting a job offer (from a specific company) is 0.17. Suppose that we observe empirically that
yarga [219]

Answer:

P (X | CI) = 0.7313

Step-by-step explanation:

X = event of getting a job

CI = Campus interview

P (X | CI) = p ( CI ∩ X) / P ( CI ) = P( CI | X)P(X) / P( CI | X)P(X) + P( CI | X')P(X')

P (X | CI) = 0.93 * 0.17 / 0.93 * 0.17 + 0.07 * (1 - 0.17)

P (X | CI) = 0.93 * 0.17 / 0.93 * 0.17 + 0.07 * 0.83

P (X | CI) = 0.1581 / 0.1581 + 0.0581

P (X | CI) = 0.1581 / 0.2162

P (X | CI) = 0.73126735

P (X | CI) = 0.7313

h = -47

Step-by-step explanation:

  1. Add 21 to each side, so it now looks like this: -6h = 282
  2. Divide each side by -6 to cancel out the -6 next to h. It should now look like this: h = -47

G(x)=3x^2-2x+7/2x+5 <br> find g(-1)
KengaRu [80]

Answer:

g(- 1) = 4

Step-by-step explanation:

To evaluate g(- 1) substitute x = - 1 into g(x)

g(- 1) = \frac{3(-1)^2-2(-1)+7}{2(-1)+5} = \frac{3+2+7}{-2+5} = \frac{12}{3} = 4
