Enter the median of the following dataset 7,15,12,13,8,11
1 answer:
The median is the value that is in the middle of a dataset.
The first step to find the median is to order the values from least to greatest:
7, 8, 11, 12, 13, 15.
Since the number of data is even, the median will be the average of the pair of values that is in the middle, in this case, 11 and 12:
The median of the data set is 11.5.

Answer:
y ≤ 2x -2 Option C.
Step-by-step explanation:
Equation of the dotted line which passes through (3,0) and (0,8) will be
y = mx+C
m = = -1
and C = 3
So equation will be y = x + 3
But shaded blue part is above the dotted line so inequality will be y> -x +3
Equation of the second solid line which passes through ( 0,-2) and (1,0) will be
y = mx + C
m = =
= 2
and C = -2
So equation of the line will be y = 2x - 2
But shaded yellow part is below the solid line.
So inequality will be
y ≤ 2x -2
Option C. is the answer.
Answer:
49243
Step-by-step explanation:
Given that the population of rabbits on an island is growing exponentially.
Let the population,
where, and b are constants, t=(Current year -1994) is the time in years from 1994.
In 1994, t=0, the population of rabbit, P=9600, so
So,
and in 2000, t=2000-1994=6 years and population of the rabbit, P=18400
b=0.109
On putting the value of P_0 and b, the population of the rabbit after t years from 1994 is
In 2009, t= 2009-1994=15 years,
So, the population of the rabbit in 2009
Hence, the population of the rabbit in 2009 is 49243.
