Answer:
If AB and CD are perpendicular, (slope of AB) x (slope of CD) = -1
9/a = -1
a = -9
<h2>
The required number is 18.</h2>
Step-by-step explanation:
Let the required number = x
To find, the required number = ?
According to question,
∴ 2x - 16 - 2 × 10 = 0
⇒ 2x - 16 - 20 = 0
⇒ 2x - 36 = 0
⇒ 2x = 36
⇒ x = 18
∴ The required number = 18
Thus, the required number is 18.
Answer:
1/3 or 0.333
Step-by-step explanation:
If we know that exactly 2 of the 6 rolls resulted in a 1. Then the number of ways to arrange the two 1s into 6 slots is
ways
Of these 15 ways, some of them have 1 at the 1 slot.
The number of ways to arrange the two 1s so that one 1 is in the 1st slot is 5. Because the 2nd 1 is in any of the other 5 slots.
Therefore, the probability that the first roll resulted in a 1,given that exactly two of the six rolls resulted in a 1 is
5 / 15 = 1/3 or 0.333
