Conduct a survey of at least 50 families in your village/city. take the data of the number of persons in a family, their ages, their educational qualification and income per family. prepare a project report concerning the following points:
(i) prepare age-wise grouped frequency distribution table.
(ii) literacy level in the village/city - elementary, secondary, senior secondary, graduation and higher level and represent it in a pie-chart.
(iii) standard deviation (sd) of the income of the families.
(iv)represent the data in part (ii) with the of bar graph also.

step-by-step explanation:

the correct answer is a) "catholic church".

the proposals that liberals in mexico made during 1855 were particularly focused on a person's individual rights, such as the freedom of speech, the freedom of conscience, freedom of assembly, and the right to possess weapons.

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
