Circle class 10

The width of each of nine classes in a frequency distribution is 2.5 and the lower class boundary of the lowest class 10.6. Then the upper class boundary of the highest class is (a) 35.6 (b) 33.1 (c) 30.6 (d) 28.1

If r% of students scored less than 33 marks, then find r, given N=50 , class size= 10 , frequency of the rth. Percentile class =12 and cumulative frequency of the rth percentile class =22 , lower limit of rth percentile class =30

The width of each of five continuous classes in a frequency distribution is 5 and the lower class limit of the lowest class is 10. The upper class limit of the highest class is

While calculating mode the following observation are found. Lower limit of modal class =40, frequency of modal class =20, frequency of previous class =12 , frequency of preceding class =11 and width of the class =10, find mode .

Arithmetic progression class 10 || Basic introduction

In a frequency distribution, the mid-value of a class is 15 and the class intervals is 4. The lower limit of the class is 10 (b) 12 (c) 13 (d) 14

Find the actual lower class limits , upper class limits and mid values of the classes : 10 -19 , 20 - 29 , 30 - 39 , and 40 - 49

If the equation of a circle of a circle is 10x^(2)-10x+y^(2)+6y=-9 , which of the following lines contains a diameter of the circle?
