Answer + Step-by-step explanation:
let R be the set of farmers cultivating rice.
let W be the set of farmers cultivating wheat.
let n be the total number of farmers.
i) Check the attachment.
ii) Card R∪W = Card R + Card W - Card R∩W
Note : Card R denotes the number of farmers cultivating rice.
Card R∪W = Card R + Card W - Card R∩W
iiI) the number of farmers who are cultivating rice only :

Answer:
y=2x+6 ; x+y=51
Step-by-step explanation:
assuming x is one number and y is the other -
one number (y) is 6 more (+6) than twice another (2x) -
using that knowledge we form an equation -
y=2x+6
the sum (x+y) is 51
using this knowledge we can make the equation -
x+y=51
now you have -
y=2x+6 or 2x-y=-6
x+y=51
using system of equations -
you add the equations -
3x=45
x=15
y=51-x => y=36
hope this helps!!
Answer:
18.=400%
Step-by-step explanation:
80/20 we get 4 then we multiple 4 ×100 we get 400 and we check the answer 400% ×20 =80
Answer:
Number of favourable outcomes i.e. ‘a card of diamond’ is 13 out of 52 cards. Therefore, probability of getting ‘a card of diamond’ Number of favorable outcomes P(D) = Total number of possible outcome = 13/52 = 1/4 (v) a king or a queen. Total number of king is 4 out of 52 cards. Total number of queen is 4 out of 52 cards
