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.

Answer:
Step-by-step explanation:
Let x be the number.
Sum of five and 8 times a number: 8x + 5
Fifty plus one half of the number: 50 + (1/2)x
Area of right-angled triangle is given by;
Area, A = 1/2 *b*h, Where b=base, h=height
Therefore,
A1 = 1/2bh = 16 in^2
A2 = 1/2 (2b)(2h) = 2bh
Ratio of increase = A2/A1 = {2bh}/(1/2bh} = 4 (the area is increased 4 times)
The,
A2 = 4*16 = 64 in^2
Therefore,
The area is increased by (64-16) = 48 in^2
Answer:
y=-2/3(x)
Step-by-step explanation:
3y=-2x-6
y=-2/3(x)-2
slope is y=-2/3(x)
