Answer:
D
Step-by-step explanation:
note that the values in the domain map to the values in the domain as
- 1 → 2 ( that is 1 + 3 = 2 )
3 → 6 ( that is 3 + 3 = 6 )
5 → 8 ( that is 5 + 3 = 8 )
In each case 3 is added to the value in the domain(x) to obtain the value in the range ( y = f(x) )
Hence f(x) = x + 3 → D
Answer:
51 correct : 9 incorrect = 17 correct / 9 incorrect
35 girls : 15 boys = 7 girls / 3 boys
Step-by-step explanation:
51 correct : 9 incorrect,
= 51 : 9
= 51 / 9
= 3 x 17 / 3 x 3
= 17 / 3
= 17 correct / 9 incorrect
35 girls : 15 boys
= 35 : 15
= 35 / 15
= 5 x 7 / 5 x 3
= 7 / 3
= 7 girls / 3 boys
Givn : OK = 3, OJ = 30, KN = 1, JM = 3
ON=OK+KN=3+1=4
OM=OJ+JM=30+10=40
In triangles OKJ & ONM,
OKOJ=330=110
ONOM=440=110
Angle O is common in both the triangles.
Two sides are in same proportion and the included angle is common (SAS) . Hence both the triangles are similar.
That means KJNM=110 or the two sides are parallel.
Hence ˆK=ˆN,ˆJ=ˆM corresponding angles.
