Answer:

Step-by-step explanation:

The mean is 59.625 because if you add all of the listed numbers together and then divide by how many numbers are listed (8) you get a mean of 59.625.

The median is 61 because you first list the numbers from least to greatest, then you see what number(s) are in the middle. Last, since there would be two (54 and 68) you then divide by 2 to get the median of 61.

The mode is 90, because it appeared two times in the list of numbers.

Last, the range is 79 because first you would list the numbers from least to greatest, then you take the lowest and higher numbers and subtract them from each other, which would be 79.

ln 5
e = ?
x
Keep in mind that y=e and y = ln x are inverse functions of one another.
ln 5
e , we can drop both the "e" and the "ln 5." We are left with 5 (answer).
ln 5
Alternatively, we could take the ln of both sides of y = e

which will result in ln y = (ln 5) ln e. Note that ln e = 1 (these two functions are inverses of one another).

Then we are left with ln y = ln 5. Dropping the "ln" operator from both sides,

y=5 (same as before).

Ray industries bought a touchscreen monitor for $1200 it is expected to depreciate at a rate of 25% per year what was the value

max2010maxim [7]

So for this problem, we will be using the exponential equation format, which is y = ab^x. The a variable is the initial value, and the b variable is the growth/decay.

Since our touchscreen starts off at a value of 1200, that will be our a variable.

Since the touchscreen is decaying in value by 25%, subtract 0.25 (25% in decimal form) from 1 to get 0.75. 0.75 is going to be your b variable.

In this case, time is our independent variable. Since we want to know the value 3 years from now, 3 is the x variable.

Using our info above, we can solve for y, which is the cost after x years.

$y=1200*0.75^3\\y=506$

In context, after 3 years the touchscreen will only be worth $506.
