Answer:

16.56 in

Step-by-step explanation:

4 sides of the squares are exposed

The radius of each semicircle is 1 since they are against 2 squares.

2pi*r=circumfrence

2pi*1=6.28

6.28/2=3.14 because it's a semicircle

3.14*4=12.56 because there are 4 equal semicircles

12.56+4=16.56

The stem-and-leaf plot shows the number of digs for the top 15 players at a volleyball tournament.
Tanya [424]

The data of players of volleyball tournament, the mean is 56.5, median is 53, range is 56 and interquartile range is 20

<h3>What is mean, median and mode of a data set?</h3>

The mean of the data is the average value of the given data. The mean of the data is the ratio of the sum of all the values of data to the total number of values of data.

The median of the data is the middle value of the data set when it arrange in ascending or descending order.

Mode of a data set is the value, which occurs most times for that data set. The value which has the highest frequency in the given set of data is known as the mode of that data set.

The stem-and-leaf plot shows the number of digs for the top 15 players at a volleyball tournament. The table is attached below.

The data according to the table is,

41,41,43,43,45,50,52,53,54,62,63,63,67,75,97

  • The mean is-

\mu=\dfrac{41+41+43+43+45+50+52+53+54+62+63+63+67+75+97}{15}\\\mu=\dfrac{849}{15}\\\mu=56.5

  • The median is.

The arranged data according to the table is,

41,41,43,43,45,50,52,53,54,62,63,63,67,75,97

Here, the middle value is 53. Thus, the median is 53.

  • The modes from least to greatest are , , and.

Mode is the data which occur most offen. Here the order of modes from least to greatest is,

41   41   43   43   45   50   52   53   54   62   63   63   67   75   97  

  • The range is.

Lowest value in data is 41 and highest is 97. Thus, the range is,

r=97-41\\r=56

  • The interquartile range is.

The third quartile of data is 63 while first quartile is 43. Thus, the interquartile range is.

IQR=63-23\\IQR=20

Thus, the data of players of volleyball tournament, the mean is 56.5, median is 53, range is 56 and interquartile range is 20.

Heeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeelp and do the order of operation
umka21 [38]

Answer:

<h3>The answer is 7/12.</h3>

Step-by-step explanation:

( \frac{2}{3}  -  \frac{1}{4} ) + ( \frac{1}{2}  \times  \frac{1}{3} )

Solve the terms in the bracket first

That's find the LCM of the ones which are subtracting

LCM of 3 and 4 is 12

That's

\frac{2}{3}  -  \frac{1}{4}  =  \frac{8 - 3}{12}  =  \frac{5}{12}

Next multiply the other terms in the other bracket

That's

\frac{1}{2}  \times  \frac{1}{3}   =  \frac{1}{6}

Add both results

That's

\frac{5}{12}  +  \frac{1}{6}

Find the LCM

The LCM is 12

We get the final answer as

\frac{5}{12}  +  \frac{1}{6}  =  \frac{5 + 2}{12}  =  \frac{7}{12}

Hope this helps you

Azizah got 1 for the slope of the line through 2 points (1,2) and (4,-1). Explain to her the mistake she made and how to find th
ololo11 [35]
(1,2)(4,-1)
slope = (y2 - y1) / (x2 - x1)
slope = (-1 - 2) / (4 - 1) = -3/3 = -1

the slope is -1......I am not sure of the mistake.....unless she just added (-1 - 2) and got 3 instead of -3.......or when dividing -3/3....she maybe forgot about the negative sign
