Answer:
2.9
Step-by-step explanation:
3.6 - 0.7 = 2.9
Answer:
∠TRS = 40°
Step-by-step explanation:
∠UTS is an exterior angle of the triangle
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles, that is
∠UTS = ∠TRS + ∠RST
9x - 15 = 3x + 16 + x + 9
9x - 15 = 4x + 25 ( subtract 4x from both sides )
5x - 15 = 25 ( add 15 to both sides )
5x = 40 ( divide both sides by 5 )
x = 8
∠TRS = 3x + 16 = (3 × 8) + 16 = 24 + 16 = 40°
Answer:
Subject B.
Step-by-step explanation:
It is given that,
There are total four subjects, namely A, B, C and D.
Out of these four subjects, we have, Subject B wants to impress the researcher above everyone while the other subjects do not care.
Since, Subject B wants to impress the researcher, they would want to use any means as possible so that the researcher gets amazed by them.
For this, it is highly possible that they will start answering questions in a way that makes them impressive, which would lead them to not answer questions honestly.
While the other subjects do not care whether the researcher is impressed, this will make them give the answer honestly.
Hence, Subject B is least likely to answer the questions honestly.
Answer:
Option B is right
Step-by-step explanation:
P(A or B)
In set theory if A and B are two sets we have either A occurs or B occurs or both as
P(A or B) = P(AUB)
This implies that A occurs or B occurs
Probability is calculated as P(A)+P(B)-P(AB)
P(AB) here represents both occurring and this is subtracted as this was added two times
Option A is wrong because this is AB
Option C is wrong because it is not necessary A occurs first
D is wrong because this is A'UB' where A' represents the complement of A
So correct answer out of four options is
B. the probability that in a single trial, event A occurs, event B occurs, or they both occur.
