Answer: If the second train arrives at the station 18 minutes after the first one DEPARTS, then there's a train waiting at the station for 2 minutes out of every 20.
So the probability a train will be there when you arrive is
2/20 = 0.1
Answer:
192g3
Step-by-step explanation:
Step 1 find the volume
6×4×10=240
Step 2 find the mass
240× 0.8g/cm3= 192g3
D because the coefficient for x is 2.5 and the value of b is positive 7
Given:
To prove:
Solution:
In triangle AED,
Two sides of triangle AED are equal, it means triangle AED is an isosceles triangle. The base angles of an isosceles triangle are equal. So,
In triangle ABE and triangle DCE,
(Given)
(Base angles of an isosceles triangle are equal)
(Given)
Two corresponding sides and their included angles are congruent. So, triangles are congruent by SAS postulate of congruence.
(By SAS postulate of congruence)
Hence proved.
