I would first order them from least to greatest
State A 21 22 22 23 23 23 24 24 25
State B 20 20 21 22 23 23 24 46 50.
now analyze data
State A
find the 'middle' value, that is your median
if you have odd number of terms , it is exact middle. if even number of terms, then take average of two adjacent middle terms.
21 22 22 23 23 23 24 24 25
median is 23
median of lower half is Q2
21 22 22 23 , median is (22 + 22) /2 = 22
median of upper half is Q3
Five point summary of state A
minimum : 21
Q1 : 22
median: 23
Q3: 24
maximum 25
IQR = 2
Five point summary of state B
minimum : 20
Q1 : 20
median: 22
Q3: 35
maximum 50
IQR = 15
Answer:
d×20/100= 18 , d=18×5= 90 , 2d=2×90=180
180×5/100= 9 , A)9
This is the concept of application of an exponential growth functions. This question can be modeled using the exponential formula;
f(t)=ae^(kt)
where;
a=initial population
f(x)=current population
t=time
k=constant of proportionality
suppose the time at 1993 is t=0 and time in 1999 is t= 6
N/B. The population is in millions;
Thus;
176=171e^(6t)
176/171=e^(6t)
introducing the natural logs we getL
6t=ln(176/171)
t=1/6ln(176/171)
t=0.0048
Hence;
f(t)=171e^(0.0048t)
Therefore the population in 2012 will be:
t=19
thus;
f(t)=171e^(0.0048*19)
f(t)=187.33
Thus, the population will be given by:
f(t)=187 million
Answer:
516 miles
Step-by-step explanation:
Mean is when you add all of them together and divide by the amount of data you collected. Mean is considered the average. So, all of them added together would be 14. Divide that by 7. You should get 2 and that is the average.
