someone please help :( a sample of the amount of rent paid for one-bedroom apartments of similar size near the University of Ore

Volgvan

Answer:

Oregon:

Median: 467.5

Mean: 451.33

Standard Deviation: 113.6

Washington:

median: 380

Mean: 396.6

Standard deviation: 56.3

Step-by-step explanation:

To calculate the median, we need to organize the price and select the value that is in the middle position.

To calculate the mean, we need to sum all the values and divide them by the number of values

To calculate the standard deviation, we need to square the distances between every price and the mean, sum it all and divide them by the number of values less 1 and finally calculate the square root.

So, for Oregon, the organized values are:

$295, $345, $460, $475, $538, $595

The median is a value between $460 and $475. it is calculated as:

$\frac{460+475}{2}=467.5$

The mean is:

$\frac{295+475+345+595+538+460}{6}=451.33$

The standard deviation is:

$\sqrt{\frac{(295-451.3)^2+(475-451.3)^2+(345-451.3)^2+(595-451.3)^2+(538-451.3)^2+(460-451.3)^2}{6-1}}=113.6$

At the same way, we can calculate the median, mean, and standard deviation for Washington and get:

median: 380

Mean: 396.6

Standard deviation: 56.3

True or False: For the depreciation formula, A = C(1 - r)t, the A value will always be greater than the C value.

pogonyaev

Answer: False

"Depreciating" means "going down", so the value is decreasing. The value of A will always be smaller than C. For example, if the item is worth $100 today and it drops to $80, then it depreciates in value. In this example, C = 100 and A = 80 so A > C is false

URGENT!! Given the inequality, the test point (2,-8) .... a) b) c) d)

sattari [20]

Answer:

B

Step-by-step explanation:

let's see, I'd the point on the line/boundary ?

for this we use the equality part (and use the coordinates of the point as x and y) :

-8 = 2×2² - 5×2 - 6 = 8 - 10 - 6 = -2 - 6 = -8

correct.

this proves that the point is on the line defined by the equation.

and that means it is on the boundary of the inequality.

because that inequality contains the boundary in the solution region (hence the >= relation instead of just >), we cannot use that point to determine which side of the boundary (incl. the boundary line, but still) is the solution region.
