 Answer:
y intercept is 0
Step-by-step explanation:
y=2/3x+b
if x=0 y=0           (0,0)
if x=3, y=2          (3,2)
y=2/3x+b
2=2+b
b=0
 
        
             
        
        
        
Answer:
The estimated mean number of rockets hits in the region is 533.
Step-by-step explanation:
We are given the following information,
Number of rocket hits     |    Observed number of regions
0                                       |                       228
1                                        |                       214
2                                       |                        94
3                                       |                        32
4                                       |                         7
5                                       |                        0
6                                       |                        0
7                                       |                         1
We are asked to estimate the mean number of rocket hits in the region.
The mean or expected value is given by

Therefore, the mean number of rockets hits in the region is 533.
