The set of life spans of an appliance is normally distributed with a mean Mu = 48 months and a standard deviation Sigma = 8 mont
natita [175]

To solve the problem we must know about Z-Score.

<h3>What is Z-score?</h3>

A Z-score helps us to understand how far is the data from the mean. It is a measure of how many times the data is above or below the mean. It is given by the formula,

Z = \dfrac{X- \mu}{\sigma}

Where Z is the Z-score,

X is the data point,

μ is the mean and σ is the standard variable.

The life span of an appliance that has a z-score of –3 is 24 months.

Given to us

  • Mean, μ = 48 months,
  • standard deviation, σ = 8 months,
  • Z-Score = -3

<h3> What is the life span of an appliance?</h3>

The life span of the appliance can be calculated using the Z-score formula,

Z = \dfrac{X- \mu}{\sigma}

Substitute the values,

-3 = \dfrac{X- 48}{8}\\\\-3 \times 8 = X - 48\\\\-24+48=X\\\\X = 24\ months

Hence, the life span of an appliance that has a z-score of –3 is 24 months.

Two functions are graphed on the coordinate plane. Which represents where f(x) = g(x)?
PilotLPTM [1.2K]
I think a word is missing here:  '<span>Which { ? } represents where f(x) = g(x)?

If the graph of f(x) intersects the graph of g(x), the coordinates of the point of intersection constitute the "solution" of f(x) = g(x).

If you were to share functions f(x) and g(x), you'd likely be able to determine the point of intersection, either algebraically or graphically.</span>

Eva8 [605]

Answer:

D. unfavorable fixed overhead flexible minus budget variance

Step-by-step explanation:

As the cost of the equipment is increasing the fixed efficiency and idle capacity variance would be unfavorable resulting in an  unfavorable fixed overhead flexible minus budget variance.

The expenses of the machinery are the fixed indirect costs which result in fixed overhead variances. Since it is related to the working of the machinery it would result in efficiency and idle capacity variances that in turn would give unfavorable fixed overhead of the flexible minus budget variance.
