Answer: 1.37 miles
Step-by-step explanation:
13.7=100%
13.7/10=1.37=10%=1/10
Answer: the population after 9 years is 17175
Step-by-step explanation:
We would apply the formula for exponential decay which is expressed as
A = P(1 - r)^ t
Where
A represents the population after t years.
t represents the number of years.
P represents the initial population.
r represents rate of growth.
From the information given,
P = 24800
r = 4% = 4/100 = 0.04
t = 9 years
Therefore,
A = 24800(1 - 0.04)^9
A = 24800(0.96)^9
A = 17175
Answer:
<h3>The probability that atleast 2 of them come up heads is 0.5</h3><h3>∴ P(A)=0.5</h3>
Step-by-step explanation:
Given that three fair coins are flipped.
<h3>
To find the probability that at least 2 of them come up heads:</h3>
Sample space for the given event is
<h3>∴ n(S)=8</h3>
Let A be the events of getting atleast 2 Heads and is given by
A = {HHH, HHT, HTH, THH}
<h3>∴ n(A)=4</h3>
Probability of Getting atleast 2 Heads in 3 Coin Tosses is
<h3>∴ P(A)=0.5</h3><h3>∴ the probability that atleast 2 of them come up heads is 0.5</h3>
Answer:
2400 km
Step-by-step explanation:
distance=rate*time
d=rt
d=(800)(t+1)
d=(1200)(t)
the right sides are both equal to d so set them equal to each other
800(t+1)=1200(t)
800t+800=1200t
800=1200t-800t
800=400t
t=800/400
t=2 hours
d=1200*2
d=2400 km
