Answer:
Step-by-step explanation:
mean = sum of data / no of data
20 + 58 + 74 + 77 + 77 + 85 + 86 + 90 + 95 + 98 / 10
760 / 10
76
to find median u should arrange the data from ascending to descending order.
since the given data is already arranged u dont need to change.
median = (N + 1)/2 (N means no of data)
=10 + 1 / 2
=11 / 2
=5.5
= 5 th term + 6 th term /2
=77 + 85 /2
=162 / 2
=81
mode means most repeating number . so in this given data 77 is repeated two times while others occured just one times . so the mode of the given data is 77.
Mode = 77

Answer:
D
Step-by-step explanation:
it's the only one where the y of each point has a linear (even if constant) trend, the others go up and down
Line II
2x+3y=-5
3y=-2x-5
y=
Gradient m=
Gradient of line I will be;
m=
Equation of line I;
y=mx+c
y=
Finding value of c by replacing for;
y=1
x=-6
1=
c=10
y=
