Answer:
102-105
Step-by-step explanation:
Median formula for a group data is expressed as shown;
Median = (N+1)/2 th value/interval
N is the total number of students
From the question N = 36
Median = (36+1)/2
Median = 37/2
Median = 18.5
Therefore we are to cumulate the value of the frequency up till the 18.5th value.
From the table
If we keep cummulating the frequency from the top;
Let's add:
1+3+5+5+8 = 21
Since the 18.5th values falls within the cumulative frequency value (i.e 21), the corresponding interval where we stopped cumulating will be our Median.
From the table, the interval with the frequency of 8 is 102 - 105. Hence the median is located at the interval 102 - 105
2x-9<7
2x<16
x<8

Answer:
y=22
Step-by-step explanation:
y=-5(-2)+12
y=10+12
y=22
If the common difference is 3 all you need to do is:
an=a1 - d(n-1)
2 - 3d + 3
Explicit rule = -3n + 5
