(0, 2), (2, 4), (4, 6), (6, 8), (8, 10)
The domain is the set of the first coordinates of the points.
The range is the set of the second coordinates of the points.
The domain = {0, 2, 4, 6, 8}
The range = {2, 4, 6, 8, 10}
Answer:
Step-by-step explanation:
Since the whole right side of that triangle is equal to 28 and the lower portion is 21, then we know the upper portion is 7. Set up a proportion using those sides and the fact that the 2 triangles are similar:
and cross multiply to get
21x = 126 and
x = 6
1) Event A = 2/3
Event B = 1/2
2) 1/2
1)
Event A :
No. we need on dice = 4
Total numbers on dice = 6
Hence sample space of the event = 6
P( getting 4) = 4/6 = 2/3
Event B :
A coin has a head & a tail.
Hence sample space of the event = 2
But as we need tail only ,
P ( getting Tail ) = 1/2 [ if only tossed once ]
2)
Total numbers on a die = 6
Total no. of odd numbers on die = 3 (∵ 1 , 3 & 5 are odd )
Sample space of this event = 6
P (getting an odd number) = 3/6 = 1/2
Total no. of houses = 140
Let there are 9x flats and 5x bungalows.
Total bungalows = 50
It means,
5x = 50
x = 10
No of flats = 9x
= 9(10)
= 90
Total houses = no. of flats + no. of bungalows
= 50+90
= 140
So, there are 140 houses in the village.

D. d = 5
d = d² - d¹
= 5 - 0
= 5
d = d³ - d⁴
= 10 - 5
d = dⁿ - dⁿ-¹
