89 is the mode, it occurs the most (3 times)
89 is also the median, it is the middle number out of the 15 numbers in the data set. It there were 14 numbers you would add the two middle numbers and divide by 2 to get the median.

What is the medium lower quartile upper quartile and interquartil of the numbers

docker41 [41]

First you find the median, by taking 893+954 and dividing the sum of those two numbers by 2. The median is 923.5. Then you take and find the median of the numbers before the median which is 513. That is your lower quartile. Then you find the median of the numbers below the median, which is 1038. That is your upper quartile. The interquartile range is your upper quartile minus your lower quartile.

Therefore, your answer would be:
Median- 923.5
Lower Quartile- 513
Upper Quartile- 1038
Interquartile Range- 525

A rectangular box has a square base. The combined length of a side of the square base, and the height is 20 in. Let x be the len

aniked [119]

Answer:

a. V = (20-x) $x^{2}$ $in^{3}$

b . 1185.185 $in^{3}$

Step-by-step explanation:

Given that:

The height: 20 - x (in )
Let x be the length of a side of the base of the box (x>0)

a. Write a polynomial function in factored form modeling the volume V of the box.

As we know that, this is a rectangular box has a square base so the Volume of it is:

V = h * $x^{2}$ $in^{3}$

<=> V = (20-x) $x^{2}$ $in^{3}$

b. What is the maximum possible volume of the box?

To maximum the volume of it, we need to use first derivative of the volume.

<=> dV / Dx = -3 $x^{2}$ + 40x

Let dV / Dx = 0, we have:

-3 $x^{2}$ + 40x = 0

<=> x = 40/3

=>the height h = 20/3

So the maximum possible volume of the box is:

V = 20/3 * 40/3 *40/3

= 1185.185 $in^{3}$

You are considering buying two different vehicles. • The first is a van at $20,523, and an estimated annual operating cost of $3

torisob [31]

Answer:

Fill in the following tables, using the equations.

Cost of owning and operating the vehicles

Vehicle 0 1 2 3 4 5 6

Van $20,523 $23,723 $26,923 $30,123 $33,323 $36,523 $39,723

Car $23,540 $25,990 $28,440 $30,890 $33,340 $35,790 $38,240

How much does each vehicle cost initially?

Van costs $20,523
Car costs $23,540

How much does each cost to operate for one year?

Van costs $3.200
Car costs $2,450

Which one initially costs less?

Which one will cost less over the six years?

When do they cost about the same?

year 4: van accumulated costs $33,323 and car accumulated costs = $33,340
