Answer:
1/169
Step-by-step explanation:
There are 4 jacks in a deck of cards.
So 4/52 is the probability of drawing 1 card
The probability of drawing 2 jacks is 4/52*4/52
Solve, and that is 1/169
I hope this helps!
Answer:
152
Step-by-step explanation:
x =7+1 = 8
8 x 19 =152
w = 37.846 mph (wind rate)
plane speed in still air: 492 mph
Answer:
Explanation:
Use the Pythagorean theorem (
a
2
+
b
2
=
c
2
)
Lets label the right triangle such that:
a
=
12
b
=
16
c
=
x
Thus,
12
2
+
16
2
=
x

144
+
256
=
x

400
=
x
2
√
400
=
x
20
=
x
So our missing side,
c
is
20
We can now say that the sides of our triangle are
12
,
16
,
20
I've included a link that lists a couple of Pythagorean triples (a couple because they are infinitely many).

Option (b) is your correct answer.
Step-by-step explanation:
Given Trigonometric expression is
So, on rationalizing the denominator, we get
We know,
So, using this, we get
We know,
So, using this identity, we get
<u>Hence, </u>
