Answer:
The answer is below
Step-by-step explanation:
We need to prove that:
(Root of Sec A - 1 / Root of Sec A + 1) + (Root of Sec A + 1 / Root of Sec A - 1) = 2 cosec A.
Firstly, 1 / cos A = sec A, 1 / sin A = cosec A and tanA = sinA / cosA.
Also, 1 + tan²A = sec²A; sec²A - 1 = tan²A
Answer:
20ml in 1 minute. 1000ml is equal to 1 litre.
Step-by-step explanation:

The number of game the softball team lose is 47 games.
<h3 /><h3 /><h3>The softball team played 149 games. </h3>
Total games played = 149 games
The team won 8 more than two times the number of games they lost.
Let
the number of games they lost = x
Therefore,
- number of game won = 8 + 2x
The number of game they lose can be calculated as follows:
8 + 2x + x = 149
8 + 3x = 149
3x = 149 - 8
3x = 141
x = 141 / 3
x = 47
Therefore, the team lost 47 games.

Answer:
(b)0.56
(c)0.38
Step-by-step explanation:
(a)The tree diagram is attached.
P(Ben Fails)=1-0.8=0.2
P(Tom Fails)=1-0.7=0.3
(b)Probability that both will pass their driving test.
P(both will pass)=0.8 X 0.7 =0.56
(c)Probability that only one of them will pass their driving test.
P(Tom Bass, Ben Fails OR Ben Pass, Tom Fails)
=(0.7 X 0.2)+(0.8 X 0.3)
=0.14+0.24
=0.38
