Answer:

<h2>B. Better measure of center: the median.</h2><h2>D. Better measure of spread: the interquartile range (IQR).</h2>

Step-by-step explanation:

The median is a measure of central tendency. Specifically, it indicates the central value of a data set, the value that is at the exact center, that is the median. That's why the median is the best measure of center for a data set.

On the other hand, the interquartile range is the difference between the first quartile and the third quartile, that is, the first and last quartile, this difference represent better the spread, because it shows the variability of the data set. This variability measure makes the interquartile range the best option of represent spread.

A strobe light is located at the center of a square dance room. the rotating light is 40 feet from each of the square walls and

Effectus [21]

The equation of the rotating light is an illustration of a secant function

The equation that represents the distance between the center of the circle and the light source is $d(t) = 40\sec(\frac{\pi}{3}t)$

<h3>How to determine the equation</h3>

The equation is a secant function represented by

$y =A\sec(Bt)$

Where:

A represents the amplitude

So, we have:

$A = 40$ --- the distance of the light from each square wall

B represents the period, and it is calculated as:

$B = \frac{2\pi}{T}$

The light completes its full rotation every 6 seconds.

This means that,

T = 6

So, we have:

$B = \frac{2\pi}{6}$

Simplify

$B = \frac{\pi}{3}$

Substitute values for A and B in $y =A\sec(Bt)$

$y = 40\sec(\frac{\pi}{3}t)$

Rewrite as a function

$d(t) = 40\sec(\frac{\pi}{3}t)$

Hence, the equation that represents the distance between the center of the circle and the light source is $d(t) = 40\sec(\frac{\pi}{3}t)$

A gift box’s rectangular base has a perimeter of 92 centimeters. The length of the base is one more than twice the base’s width.

kozerog [31]

Assume that the length of the rectangle is "l" and that the width is "w".

We are given that:
(1) The length is one more than twice the base. This means that:
l = 2w + 1 .......> equation I
(2) The perimeter is 92 cm. This means that:
92 = 2(l+w) ...........> equation II

Substitute with equation I in equation II to get the width as follows:
92 = 2(l+w)
92 = 2(2w+1+w)
92/2 = 3w + 1
46 = 3w + 1
3w = 46-1 = 45
w = 45/3
w = 15

Substitute with w in equation I to get the length as follows:
l = 2w + 1
l = 2(15) + 1
l = 30 + 1 = 31

Based on the above calculations:
length of base = 31 cm
width of base = 15 cm

2. You deposit $1200 into a bank account. Every year that accounts increase by 15 %.

lord [1]

Answer:

Exponential Growth, 1200(1.15)

Step-by-step explanation:

It is a Growth function because it is "increasing" yearly. The equation is multiplying with 1.15 because when it is increasing, you need to add 1 to the percentage rate.
