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

$\mu = \sum (x \cdot P(x)) \\\\\mu = (0 \cdot 228) + (1 \cdot 214) + (2 \cdot 94) + (3 \cdot 32) + (4 \cdot 7) + (5 \cdot 0) + (6 \cdot 0) + (7 \cdot 1) \\\\\mu = 0 + 214 +188+ 96 +28 +0+ 0 + 7 \\\\\mu = 533$

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

Find the product of the greatest common divisor and the least common multiple of 18 and 42.

Evgesh-ka [11]

The product of the greatest common divisor and the least common multiple of two numbers is always the product of the two numbers. So, you have

$\text{lcm}(18,42)\times\text{GCD}(18,42)=18\times 42=756$

Solve by using factorizing method:4x²-36x+81=0

boyakko [2]

Answer:

x = 4.5

Step-by-step explanation:

4x² - 36x + 81 = 0
(2x)² - 2*2x*9 + 9² = 0 Identity a² - 2ab + b² = (a - b)²
(2x - 9)² = 0
2x - 9 = 0
2x = 9
x = 4.5
