Answer:

A typical example would be when a statistician wishes to estimate the ... by the standard deviation ó) is known, then the standard error of the sample mean is given by the formula: ... The central limit theorem is a significant result which depends on sample size. ... So, the sample mean X/n has maximum variance 0.25/ n.

A car was Skid to a half a uniform rate of -9.4 m/s ^2 squared if the measure skid marks that are 34 m long with what speed is t
babymother [125]

Answer:

vi = 25.28 m/s

Step-by-step explanation:

a = -9.4 m/s²

x = 34 m

vf = 0 m/s

vi = ?

We can apply the equation

vf² = vi² + 2*a*x

⇒     vi = √(vf² - 2*a*x)

⇒     vi = √((0 m/s)² - 2*(-9.4 m/s²)*34 m)

⇒     vi = 25.28 m/s

Answer:

  • -1, 9, - 21, 69

Step-by-step explanation:

<u>Given recursive formula:</u>

  • a₁ = -1
  • aₙ = - 3aₙ₋₁ + 6 for n ≥ 2

<u>The first 4 terms are:</u>

  • a₁ = - 1, given
  • a₂ = - 3*(-1) + 6 = 3 + 6 = 9
  • a₃ = - 3*(9) + 6 = - 27 + 6 = - 21
  • a₄ = - 3*(-21) + 6 = 63 + 6 = 69
