Answer:
53
Step-by-step explanation:
Take the mean of each row in the accidents reported column so for example 0-4 would be 0+4/2 = 2
Then times it by the frequency which in this case is 15:
2 x 15 = 30
Do this for each rows and then add it all up:
30 + 28 + 120 + 34 = 212
Then divide it by number of row which in this case is 4:
212/4 = 53
Answer:
7.75 ( 7.8 to 1 dp)
Step-by-step explanation:
Mean = sum of frequency over total number of items ( in this case 4 items )
Hence Mean = 31/ 4
Mean = 7.75 ( 7.8 to 1dp)

3(x + 6) = x - 2
3(-4+6)= -4-2
mutiply the bracket by 3
(3)(-4)= -12
(3)(6)= 18
-12+18= -4-2
6= -4-2
6= -6
