Answer: 18.7

Step-by-step explanation:

Find the lengths of AB, BC, and CA

AB = \sqrt{(4-(-1))^{2} + (-1-4)^{2} } = 5\sqrt{2} ≈ 7.1

BC = \sqrt{(0-(-1))^{2} + (-3-4)^{2} } = 5\sqrt{2} ≈ 7.1

CA = \sqrt{(0-4)^{2} + (-3-(-1))^{2} } = 2\sqrt{5} ≈ 4.5

7.1 + 7.1 + 4.5 = 18.7

A healthcare industry is reviewing the number of liabilities each location has. Location A has a z-score of −1.12 and Location N
elixir [45]

Answer:

0.8686    or  86.86 %

0.2148     or 21.48  %

Step-by-step explanation:

In z table the value of z > - 1,12  is   0.1314 (value from the z point to the left of the curve ) then 1 - 01314 will be value from z point to the right

Again from z table we get for z = - 0.79 the value  0.2148 s the vale from the point up to the left tail

What is the equation of the line that passes through the point (-5,5)and has a slope of -1
erastova [34]

Answer:

<h2>           y = - x  </h2>

Step-by-step explanation:

The point-slope form of the equation is y - y₀ = m(x - x₀), where (x₀, y₀) is any point the line passes through and m is the slope:

m = -1

(-5, 5)    ⇒   x₀ = -5,  y₀ = 5

The point-slope form of the equation:

y - 5 = -1(x + 5)

So:

y - 5 = -x - 5         {add 5 to both sides}

y = -x             ←  the slope-intercept form of the equation
