Answer:
C
Step-by-step explanation:
A ) The rate at which rumor spreads speed up over time. If t increases, also N(t) increases, because 300 is divided by the smaller number.( Correct )B ) 1 = 300 / ( 1 + 299 · e^(-0.36 · 0 ) ) 1 = 300 / ( 1 + 299 · 1 ) 1 = 300 / 3001 = 1 ( Correct )C ) 100 = 300 / ( 1 + 299 · e^(-0.36 · 14 ) )100 = 300 / ( 1 + 299 · 1/154.47 )100 = 300 / 2.93565100 ≈ 102.192 ( Correct ) - approx. 14 minutes
D ) N = 300 / ( 1 + 299 · e^(-∞) )N = 300 / ( 1 + 299 · 0 ) N = 300 / 1 = 300299 people are enclosed space ( Not correct )Answer:True statements are: A ) , B ) and C ) .
546-314=232
That's the answer
the square root of 25 is 5 i hope this helped and enjoy your day!
Answer:
38.117%
Step-by-step explanation:
Firstly, what you do is to calculate the z-score of both points
Mathematically;
z-score = (x-mean)/SD
where mean = 70 and SD = 5
For 68, z-score = (68-70)/5 = -2/5 = -0.4
for 73, z-score = (73-70)/5 = 3/5 = 0.6
The probability we are to calculate ranges from
P(-0.4<z<0.6) = P(z<0.6) - P(z<-0.4)
it is at this point that we make use of z score table
= 0.38117 which is 38.117%
