This question is simply conversions
we know there are 100 cm in a m so..
50 × 100 = 5,000 cm/s
and we know there are 1,000 m in a know so..
50 ÷ 1,000 = 50/1,000 = 1/20 km/s
Answer:
<u>1/8910720</u>
Step-by-step explanation:
Number of ways they can be chosen :
⇒ 17 × 16 × 15 × 14 × 13 × 12
⇒ 272 × 15 × 14 × 13 × 12
⇒ 4080 × 14 × 13 × 12
⇒ 57120 × 13 × 12
⇒ 742560 × 12
⇒ <u>8910720</u>
Hence, the probability will be :
⇒ P = 1 / number of ways
⇒ P = <u>1/8910720</u>
No the rectangle cannot have x = 60 and y = 11 because x = 48 + 2y
4 people in 60 minutes =
1 person in 15 minutes
3 people = 45 minutes
By definition of the binomial coefficient,
so we have
as required.
