350 -400     375           2       0.4                50    1    

     50    1      

The solution of part (b),(c),(d) and (e) is in attached word file

Step-by-step explanation:

In part a) we take the interval size of 50 and then the resulting 8 classes are  0-50,50-100,100-150,150-200,200-250,250-300,300-350,350-400. The mid points are calculating by adding lower class interval and upper class interval and then dividing it by 2 such as for 1st class 0+50/2=25. The column frequency represents the number of data values occurring in the respective class. Cumulative frequency is computed by adding the frequency of respective class to next class frequency.It remains same for 1st class and for the 2nd class 20+16=36 and so on.  The relative frequency is computed by dividing the frequency by the sum of frequency such as for the 1st class 20/50=0.4 . The cumulative relative frequency is calculated by the same procedure by which the cumulative frequency is calculated.

b)  The frequency histogram is constructed by taking the frequency on y-axis and data set values on x-axis. The resulting histogram is rightly skewed.

c) A frequency polygon is constructed by making the line chart and considering the frequency on y-axis and data set values on x-axis.

d) The relative frequency histogram is constructed by taking the relative frequency on y-axis and data set values on x-axis. The resulting histogram is rightly skewed.

e) An ogive is constructed by making the line chart and considering the cumulative frequency on y-axis and data set values on x-axis.

Seven and thirty twp hundreths plus two and one tenth times two and seven tenths minus 18a
alexdok [17]
Answer:  Write the expression as:

" 70 \frac{32}{100} +
                         2\frac{1}{10} * 2\frac{7}{10 − 18a " ; 
______________________________________________________
or;  write as:
______________________________________________________
           " 70.32  + (2.1) * (2.7)  − 18a " ; 
______________________________________________________

To simplify:
______________________________________________________

  Using "PEDMAS" (the "order of operations") ; 

the "multiplication" comes first; 

So:  →  "(2.1) * (2.7) =  5.67 " .

And rewrite:
______________________________________________________
 " 70.32  + 5.67 − 18a " .

Now:  " 70.32 + 5.67 = 75.99 " ; 

So, we can the final simplified expression as:
______________________________________________________
   " 75.99  −  18a " ;  

or; write as:  " 75\frac{99}{100}  −  18a " .

Math help guys how wouls i work this out
Andrei [34K]

8 > 7 + \frac{x}{6}   Subtract 7 from both sides

1 > \frac{x}{6}   Multiply both sides by 6

6 > x   Flip it around so it's easier to read

x < 6

You can graph your answer by drawing an open circle at the 6 and coloring the line to the left. The circle should be open, because x is <em>less than 6</em>, not less than or equal to. You would color to the left to show that x can be anything less than 6.

Determine whether each relation is a function <br> X=-2 <br> Y=2
mash [69]
X = -2 would not be a function because if you graph it, it is a vertical line. 
Y = 2 is a function because when graphed, it is shown as a horizontal line and passes the vertical line test.

Find the surface area Sphere: area of the great circle ~ 28.6 in2
kari74 [83]
Area of a circle is πr².

Therefore we can get the radius of the great circle (and thus the sphere) by doing √(A / <span>π).
</span>
√(28.6 / <span>π) = 3.017 to 3DP.
</span>

Surface area of a sphere is 4πr².

4<span>π(3.017)</span>² = 114.4 to 1DP
