<h2><u><em>Answer:</em></u></h2>
-6*x+y-(3)<0
-6x + y - 3 = -1 • (6x - y + 3)
Explanation:
The question is given below as

We will apply the pedmas rule below
P – Parentheses [{()}]
E – Exponents (Powers and Roots)
MD- Multiplication and Division (left to right) (× and ÷)
AS – Addition and Subtraction (left to right)
By applying the rule, we will have
![\begin{gathered} \begin{equation*} [1+(11+31)\div6)\times5 \end{equation*} \\ [1+\frac{42}{6}]\times5 \\ [1+7]\times5 \\ 8\times5=40 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Cbegin%7Bequation%2A%7D%20%5B1%2B%2811%2B31%29%5Cdiv6%29%5Ctimes5%20%5Cend%7Bequation%2A%7D%20%5C%5C%20%5B1%2B%5Cfrac%7B42%7D%7B6%7D%5D%5Ctimes5%20%5C%5C%20%5B1%2B7%5D%5Ctimes5%20%5C%5C%208%5Ctimes5%3D40%20%5Cend%7Bgathered%7D)
Hence,
The final answer is
Answer:
(10,-3)
Step-by-step explanation:
Given:
μ = 500 days, the population mean
σ = 60 days, the population standard deviation
Therefore
μ + σ = 560
μ - σ = 440
μ + 2σ = 620
μ - 2σ = 380
μ + 3σ = 680
μ - 3σ = 320
The figure shown below illustrates the normal distribution
About 68% of the total area lies in x = (μ-σ, μ+σ)
About 95% of the total area lies in x = (μ-2σ, μ+2σ)
About 99.7% of the total area lies in x = (μ-3σ, μ+3σ).
