Answer:

Option D) s = 1

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 69

X = 68

Formula:

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

Computing z-scores for different standard deviation:

z_1 = \displaystyle\frac{68-60}{4} = 2\\\\z_2 = \displaystyle\frac{68-60}{3} = 2.667\\\\z_3= \displaystyle\frac{68-60}{2} = 4\\\\z_4 = \displaystyle\frac{68-60}{1} = 8

The standard deviation with highest z-score gives the most extreme position in the distribution.

Thus, the most extreme position of X = 68 in the distribution is given by a standard deviation of 1.

Option D) s = 1

Julissa is printing out copies for a work training. it takes 4 minutes to print a color copy, and it takes 2 minutes to print a
melisa1 [442]

The system of inequalities represents the number of color copies, x, and grayscale copies, y, that julissa can print to meet her goal is;

x + y ≥ 8

x + y ≥ 84x + 2y ≤ 25

<h3>Inequality</h3>

let

  • Number of color copies = x
  • Number of grayscale copies = y

  • Time to print color copies = 4 minutes
  • Time to print grayscale copies = 2 minutes
  • Total copies = 8
  • Total time = 25 minutes

x + y ≥ 8

4x + 2y ≤ 25

I think it's the first three.
-7.5 < -7
-4 < -3
-0.5 < -1
(those are the inequalities after i put each of the values for x in the original equation)

Colin buys a car for £15500.
timama [110]

Answer:

£14889.30

Step-by-step explanation:

The cost of the car = £15500.

For the first year,

depreciation = £15500 x 1%

                     = £155

Its worth after the first year = £15500 - £155

                             = £15345

For the 2nd year,

depreciation = £15345 x 1%

                     = £153.45

Its worth after the second year = £15345 - £153.45

                                 = £15191.55

For the 3rd year,

depreciation = £15191.55 x 1%

                      = £151.9155

Its worth after the third year = £15191.55 - £151.9155

                                            = £15039.6345

For the 4th year,

depreciation = £15039.6345 x 1%

                     = £150.3963

Its worth after the fourth year = £15039.6345 - £150.3963

                                             = £14889.2382

Thus, the worth of the car in 4 years would be £14889.30
