Answer:

45 sides

Step-by-step explanation:

If each of the interior angles is 172 degrees, then each of the exterior angles is 8 degrees. Since the sum of the exterior angles of any polygon is 360 degrees, there are 360 / 8 = 45 exterior angles and 45 sides.

kaheart [24]

2x+8x=30. x= #of pens

10x=30. combine like terms

x=3. divide by 10 to isolate (get by itself) x

2(3)=6. the # of white pens are represented by 2x

6 white pens

Using the median concept, it is found that it suffered a 11.16% decrease.

<h3>What is the median of a data-set?</h3>

It is the 50th percentile of the data-set, which is the value that separates the lower 50% from the upper 50%.

In this problem, the ordered data-set, in thousands of £, is given by:

{19.4, 39.8, 42.3, 42.5, 45.1, 47.9, 52.4, 53.5}

It has even cardinality, hence the median is the mean of the 8/2 = 4th and 5th terms, so:

M = (42.5 + 45.1)/2 = £43800.

It decreased from £49300 last year. The percentage decrease is the change divided by initial amount and multiplied by 100%, hence:

P = (49300 - 43800)/49300 x 100% = 11.16%.

Emily designed a robot that could climb down steps. She drew a graph to show the results from a test of her new robot. The graph

kifflom [539]

So youre a given two points. The points (0,15) and (150,0). First solve the slope of the graph

M = (y1 – y2) / (x1 – x2)

M= (15 – 0) / ( 0 – 150)

M = - 0.1

Using point (15,0)

15 = -0.1(0) + b

15 = b

So y = mx + b

Y = -0.1x + 15

Given that the data distribution is approximately normal with the minimum value of 15 and the maximum value of 98 a) Estimate th

andrew11 [14]

Answer:

a) Mean, median, mode = 56.5

b) $S = 20.75$

Step-by-step explanation:

Normally distributed data have the same value for the mean, median and mode. This value is the addition of the maximum value by the minimum, divided by 2.

Also, the standard deviation in a normally distributed sample can be approximated by the following formula:

$S = \frac{max - min}{4}$

a) Estimate the values of Mean, Median, and Mode.

Highest value = 98

Minimum value = 15

$\mu = \frac{98 + 15}{2} = 56.5$

b) Estimate the value of the standard deviation of these data

Max = 98

Min = 15

$S = \frac{max - min}{4}$

$S = \frac{98 - 15}{4}$

$S = 20.75$
