Prob(a head on 1 toss) = 1/2

So probability of 8 heads in a row = (1/2)^8 = 1/256 or close to 0.391%

If p() = x2 - 1 and q(x) - 5(x-1), which expression is equivalent to (p - q)(x)?
TiliK225 [7]

Answer:

\text{If p(x) = x2 - 1 and q(x) = 5(x - 1), the expression which is equivalent to} \text{ (p - q)(x) is (x2 - 1) - 5(x - 1).}

Step-by-step explanation:

Given:

  • p(x) = 2x2 - 1
  • q(x) = 3(x - 1)

To find:

  • (p - q)(x)

We know:

  • (p - q)(x) = p(x) - q(x)

Substitute

  • (2x^2 - 1) - 3(x - 1)

\text{Therefore, the expression equivalent to (p - q)(x) is (2x2 - 1) - 3(x - 1).}

I need help pleaseee!!!
ZanzabumX [31]

Answer: x = 57

Step-by-step explanation:

Since CD = AC, triangle ACD is isosceles, therefore

ADC = DAC

ADC + DAC + 112 = 180

ADC + DAC = 180 -112 = 68

ADC + DAC = 68/2 = 34

DEB = 180 - 34 - 23 = 123 (sum of interior angles of a triangle = 180)

Therefore, x = 180 - 123 = 57  (DEB and x are supplementary angles)
