Step-by-step explanation:
Step-by-step explanation:
Equ of line -
y=mx+c
Using point (3,-1)
3 as x, - 1 as y
M=2/3
Substitute the values of these coordinates
3=2/3(-1) +c - - - - now find for c
c= 3- (-2/3)
c= 3.67
Now with the value of c, put the values back into the equation form .. Assuming we don't have a point to work with
y=2/3x + 3.67
Answer:
Step-by-step explanation:
From the information on 60 students we write frequency distribution as
x 1 2 3 4 5 6 7 total
f 13 22 15 6 3 0 1 60
C 13 35 50 56 59 59 60
xf 13 44 45 24 15 0 7 148
x^2f 13 88 135 96 75 0 49 456
Mean = 2.67
Var = 445.92
Std dev = 21.21
I quartile = 2
III quartile = 3
20% have atmost 1
