Outcomes of democracy class 10 part 2

In a frequency distribution, the mid values of a class is 10 and width of the class is 6 . The lower limit of the 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 .

The starting value of the model class of a distribution is 20. The frequency of the model class is 18. The frequencies of the classes preceeding and succeeding are 8,10 and the width of the model class is 5, then mode is

Class 10 polynomial

The outcome of each of 30 items was observed , 10 items gave an outcome (1)/(2)-d each, 10 items gave outcome (1)/(2) each and the remaining 10 items gave outcome (1)/(2) +d each. If the variance of this outcome data is (4)/(3) , then |d| equals

A coin is tossed three times and outcomes are recorded .Use the product rule to determine the number of possible outcomes . Then list all the outcomes.

In a certain mathematics class, the part of the class that are members of the math club is 50% of the rest of that class. The total number of math club members in this class is what percent of the entire class?

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

Which one is not a requirement of a binomial distribution? a. There are 2 outcomes for each trial b. There is a fixed number of trials c. The outcomes must be dependent on each other d. The probability of successes must be the same for all the trials.
