(ii) Show that the sequence of amount in the account at the end of each year forms a geometric progression

b) Aadarsh, Babil and Charanjeet were playing a game in which they have to place rice grains on a 3 X 3 checkerboards consisting of 9 squares, each having a number from 1 to 9 written on it, as shown below.
Aadarsh arranged the rice grains on each square such that the number of rice grains is equal to the number written on the squares. i.e. He put one (1) grain on the square marked "1", two
(2) grains on the square marked "2", and so on.
Babil arranged the rice grains on each square such that the number of rice grains is equal to the square of the number written on the squares. i.e. He put one grain (= 12) on the square
marked "1", four (= 22) grains on the square marked "2", and so on.
Charanjeet arranged the rice grains on each square such that the numberof rice grains isequal to the cube of the number written on thesquares. i.e. He put one (= 13) grain on thesquare marked "1", eight (= 23) grains on the square marked "2", and so on.
Find the ratio of the total number of rice grains arranged on the checkerboard by Aadarsh, Babil and Charanjeet, respectively

He has rods of length 2.45 m, 1.80 m and 2.2 m using which he made the shed frame. Find the angles (∠A,∠B,∠C) to which the sticks are arranged with one another to form the triangular frame as shown in the figure.
Also verify sine formula for this triangle.

6. Answer any one out of the following questions.

a) There are thirteen cards in each of the four suits in a regular 52-card deck: clubs (♣), diamonds (♦), hearts (♥), and spades (♠).

(i) If a card is selected from a well shuffled deck of 52 cards, what is the probability of drawing
(a) a club ?
(b) a black king ?
(c) a queen of spade ?
(d) a red spade?

(ii) A card is drawn from a pack of 52 cards so that each card is equally likely to be selected. Check whether the following events are independent?
Event A : the card drawn is a diamond
Event B : the card drawn is a queen

Poor air quality generally impacts children, the elderly, and people with respiratory or cardiovascular conditions first. Governmental organizations typically advise citizens to limit their outdoor physical activity or perhaps stay indoors entirely when the Air Quality Index (AQI) is high.

To present status of the air quality and its effects on human health, the following description categories have been adopted Monthly AQI of two different cities A and B have been given in the following table. Based on the table and above information answer the following questions:

(i) What is the range of the data of AQI for city – A and city – B?
(ii) Calculate the mean of the data of AQI for city – A and city – B?
(iii) Based on the mean AQI levels over the year, which city has cleaner air?
(iv) Find the variance and standard deviation of the AQI data for city – A and city – B?
(v) Which city A or B shows greater variablility in AQI levels?
