I think the equation that can be used it like 1,000x+9=2700 because if you miltipuly it by 9 you get your number
Answer:
yes that is the correct answer. 41/100 are filled, so it is 41%.
Step-by-step explanation:
Answer:
If 4/8 cm = 25 miles
If 4.8 cm = 240 miles
If 48 cm = 2400
Step-by-step explanation:
4/8 x 50
4.8 x 50
48 x 50
I was unsure if there was a fraction bar or decimal. or if it was 48 so I gave all possibilities.
With n tosses, there are a total of 2^n possible outcomes. We need 15 of theses to be heads.
Since the tosses are random, we want to count the ways to have exactly 15 of them being heads. That will be C(n,15) ways to pick which tosses are heads.
The probability will be given by:
C(n,15)/2^n=0.0148
At this point we use various values of n until we get the correct probability.
n=18⇒0.003112793
n=19⇒0.007392883
n=20⇒0.014785767
n=21⇒0.025875092
Answer:
n=20
