A manufacturing firm tests job applicants. Test scores are normally distributed with a mean of 500 and a standard deviation of 5
Blababa [14]

Answer:

The probability that the candidate score is 600 or greater

P(X≥ 600 ) = 0.0228

Step-by-step explanation:

<u><em>Step(i)</em></u>:-

Given mean of the Population = 500

Given standard deviation of the Population = 50

Let 'X' be the random variable in normal distribution

Given  X = 600

Z = \frac{x-mean}{S.D} = \frac{600-500}{50} = \frac{100}{50} =2

<u><em>Step(ii)</em></u>:-

The probability that the candidate score is 600 or greater

P(X≥ 600 ) = P(z≥2)

                  = 0.5 - A(2)

                 = 0.5 -0.4772

                = 0.0228

<u><em>Final answer</em></u>:-

The probability that the candidate score is 600 or greater

P(X≥ 600 ) = 0.0228

Can someone please help me find the horizontal asymptote of this graph I dont undestand
Andreas93 [3]

9514 1404 393

Answer:

  p = 0

Step-by-step explanation:

The graph is of an exponential function. An exponential function always has a horizontal asymptote of 0.

  p(t) = 5×2^t

  p(t) → 0 as x → -∞

The horizontal asymptote is p = 0.

Write a recursive formula for the explicit formula.
Setler79 [48]

Answer: A

Step-by-step explanation:

A_n=9+(n-1)*(-4)\\\\A_1=9+(1-1)*(-1)=9+0=9\\\\A_{n-1}=9+((n-1)-1)*(-4)\\\\A_n-A_{n-1}=9+(n-1)*(-4)-(9+(n-2)*(-4))=-4n+4+4n-8=-4\\\\\boxed{A_n=A_{n-1}-4}\\\\\\Answer\ A
