The initial cost of an office fax machine is $100. After 1 year, its value becomes $80. Which is the correct linear depreciation
Elis [28]

Answer:

y=100-20x

Step-by-step explanation:

Let the x-axis be the time (in years) and the y-axis the value of the fax machine (in dollars).

We know that the initial value of the fax machine is $100; in other words, when the time is zero years, the value is $100, or as an ordered pair (0, 100). We also know that after 1 year the value decreases to $80, so (1, 80).

Now we can find the slope of the line passing through those two points using the slope formula

m=\frac{y_2-y_1}{x_2-x_1}

where

m is the slope

(x_1,y_1) are the coordinates of the first point

(x_2,y_2) are the coordinates of the second point

Replacing values:

m=\frac{80-100}{1-0}

m=-20

Now, to complete our model we are using the point slope formula

y-y_1=m(x-x_1)

where

m is the slope

(x_1,y_1) are the coordinates of the first point

Replacing values:

y-100=-20(x-0)

y-100=-20x

y=-20x+100

y=100-20x

We can conclude that the correct linear depreciation model is y=100-20x

zhuklara [117]

Answer:

<u>50</u>

Step-by-step explanation:

<u>Changing into complex form:</u>

(6 + 8i) * (3 - 4i)

= 18 - 24i + 24i - 32 (i^2)

= 18 - 32(-1)

= 18 + 32

= <u>50</u>

After collecting the data, Maria finds that the number of points per game for a certain basketball player is normally distribute
kolezko [41]

Answer:

Step-by-step explanation:

Since the number of points per game for a certain basketball player is normally distributed, we would apply the formula for normal distribution which is expressed as

z = (x - µ)/σ

Where

x = number of points per game

µ = mean

σ = standard deviation

From the information given,

µ = 14 points

σ = 2 points

The probability that in a randomly selected game, the player scored more than 8 points is expressed as

P(x > 8) = 1 - P(x ≤ 8

For x = 8,

z = (8 - 14)/2 = - 3

Looking at the normal distribution table, the probability corresponding to the z score is 0.00135

P(x > 8) = 1 - 0.00135 = 0.9987

Converting to percentage, it becomes

0.9987 × 100 = 99.87%
