The stock price for International Business Machines (IBM) historically has followed an approximately normal distribution (when a

Answer:

0.494 is the probability that on a selected day the stock price is between $186.26 and $192.47.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = $188.876

Standard Deviation, σ = $4.6412

We are given that the distribution of stock price is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P(stock price is between $186.26 and $192.47)

$P(186.26 \leq x \leq 192.47) = P(\displaystyle\frac{186.26 - 188.876}{4.6412} \leq z \leq \displaystyle\frac{192.47-188.876}{4.6412}) = P(-0.5636 \leq z \leq 0.7743)\\\\= P(z \leq 0.7743) - P(z < -0.5636)\\= 0.781 - 0.287 = 0.494 = 49.4\%$

$P(186.26 \leq x \leq 192.47) = 49.4\%$

0.494 is the probability that on a selected day the stock price is between $186.26 and $192.47.

What is the complete pattern?<br> _______ 8,570 ________ 85.7 8.57 _______

laila [671]

<span>The Complete pattern is 85,700, 8,570, 857, 85.7, 8.57, 0.857.It is nothing but just moving the decimal places to the right side.Otherwise each number should multiplied and divided by 10 so that we derived the complete pattern.When you multiply by moving the decimal point to the right, you also need to add a zero to the end of it. This is an alternative method for the pattern.</span>
