5 0

Answer:

d)    \frac{13 - 5x}{2x -8}    

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given expression

                               \frac{\frac{3}{x-2}-5 }{2-\frac{4}{x-2}  }

we will do L.C.M  both numerator term and denominator term

                     ⇒    \frac{\frac{3-5(x-2)}{x-2} }{\frac{2(x-2)-4}{x-2}  }

on simplification , we get

                 

                ⇒    \frac{\frac{13-5x}{x-2} }{\frac{2x-8}{x-2}  }

cancellation 'x-2'

we will get

          \frac{13 - 5x}{2x -8}

Step-by-step explanation:

We are given the following in the question:

Sample mean, \bar{x} = $3120

Sample size, n = 40

Population standard deviation, σ = $677

The distribution of earnings of college is a normal distribution.

Conditions:

Find the length of GI in the triangle below. Show your work.
love history [14]

Answer:

<u>The length of GI is 90.06 units</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

GH = 60 units

HI = 42 units

∠H = 123°

2. Using the Law of Cosines, we can find the length of GI, this way:

GI² = GH² + HI² - 2 * GH * HI * cos ∠H

Replacing with the real values:

GI² = 60² + 42² - 2 * 60 * 42 * cos ∠123°

GI² = 3,600 + 1,764 - 2 * 60 * 42 * -0.545

GI² = 3,600 + 1,764 - 2 * 60 * 42 * -0.545

GI² = 3,600 + 1,764 + 2,746.8

GI² = 8,110.8

<u>GI = √ 8,110.8 = 90.06 units</u>
