The probability distribution of the random variable X represents the number of hits a baseball player obtained in a game for the 2012 baseball season. x 0 1 2 3 4 5 Upper P (x )0.1664 0.3302 0.2933 0.1485 0.0369 0.0247 The probability distribution was used along with statistical software to simulate 25 repetitions of the experiment (25 games). The number of hits was recorded. Approximate the mean and standard deviation of the random variable X based on the simulation. The simulation was repeated by performing 50 repetitions of the experiment. Approximate the mean and standard deviation of the random variable. Compare your results to the theoretical mean and standard deviation. What property is being illustrated?
Answers
The table below shows the number of hits for 25 and 50 repetitions.
Answer and Step-by-step explanation: Expected Value or Mean of a probability distribution is calculated as:
E(X) = μ = ∑xP(X)
In a game for the 2012 baseball season, expected value is:
[tex]\mu=0(0.1670)+1(0.3320)+2(0.2864)+3(0.1499)+4(0.0381)+5(0.0266)[/tex]
μ = 1.640
Standard Deviation (σ) of a probability distribution is:
[tex]\sigma=\sqrt{\Sigma (x-\mu)^{2}P(X)}[/tex]
[tex]\sigma = \sqrt{(0-1.640)^{2}(0.1670)+...+(5-1.640)^{2}(0.0266)}[/tex]
σ = 1.1883
The simulate experiment of 25 repetitions shows a table. With this table, it is possible to create a frequency table as follows:
x | f
0 | 4
1 | 7
2 | 11
3 | 2
4 | 1
With a frequency table, expected value is calculated as:
[tex]\mu=\frac{\Sigma (fx)}{\Sigma f}[/tex]
[tex]\mu=\frac{0*4+1*7+2*11+3*2+4*1}{25}[/tex]
μ = 1.56
Standard deviation, using a frequency table, is calculated as:
[tex]\sigma = \sqrt{\frac{n\Sigma (fx^{2})-(\Sigma fx)^{2}}{n(n-1)} }[/tex]
[tex]\sigma=\sqrt{\frac{25(0*4^{2}+...+4*1^{2})-(0*4+...+4*1)^{2}}{25(24)} }[/tex]
σ = 0.983
The same can be done for 50 repetitions.
The frequency table is
x | f
0 | 6
1 | 18
2 | 16
3 | 9
4 | 1
[tex]\mu=\frac{0*6+1*18+2*16+3*9+4*1}{50}[/tex]
μ = 1.62
[tex]\sigma=\sqrt{\frac{50(0*6^{2}+...+4*1^{2})-(0*6+...4*1)^{2}}{50(49)} }[/tex]
σ = 0.9775
Comparing expected values and standard deviations, observe that the bigger the repetition of the experiment, mean and standard deviation get closer to the theoretical statistical values. This is an example of the Law of Large Numbers, a theorem stating as the number of random, normally distributed values increase, their sample mean approaches the theoretical mean.

Step-by-step explanation:
make 5 2/3 an improper fraction. Then multiply it by the inverse of the next number. 17/3 x 10/3 = 170/9 or 18 8/9
[tex] = 5 \frac{2}{3} \div \frac{3}{10} [/tex]
[tex] = \frac{(3 \times 5 + 2)}{3} \div \frac{3}{10} [/tex]
[tex] = \frac{17}{3} \div \frac{3}{10} [/tex]
[tex] = \frac{17}{3} \times \frac{10}{3} [/tex]
[tex] = \frac{170}{9} [/tex]
[tex] = 18 \frac{8}{9} [/tex]
[tex]therefore \: , 5\frac{2}{3} \div \frac{3}{10} = 18 \frac{8}{9} [/tex]

- 4x + 9y = 9

Answers
Answer:
y = 1, x = 0
Step-by-step explanation:
multiply -4x +9y = 9 by -2 to get 8x -18y = -18
combine the two equations to get -8y = -8
divide both sides by -8 to get y = 1
plug in 1 as the y into one of the equations and solve to get x = 0
Answer:
(0,1)
x = 0
y = 1
Step-by-step explanation:
(-4x + 9y = 9)-8
(-8x + 10y = 10)4
32x - 72y = -72
-32x + 40y = 40
-32y = -32
y= -32/-32
y=1
-4x + 9(1) = 9
-4x + 9 = 9
-4x = -9 + 9
-4x = 0
x = 0/-4
x = 0

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
The difference in the price of 2 TVs is $217.45.
One TV costs = $450.5
So, 450 - Another Tv Cost = 217.45
Another Tv Cost = 217.45+ 450.5
Another Tv Cost = $677.95
Hence, the cost of another TV is $677.95

Please include work!
Answers
Answer:
x = ± 4
y = - 2
Step-by-step explanation:
y = 0.5x² - 10 ------------------------(I)
y = -x² + 14 ------------------------(II)
Substitute the y value in equation (II)
0.5x² - 10 = -x² + 14 {Add x² to both sides}
0.5x² + x² -10 = 14 {combine like terms}
1.5x² - 10 = 14 {Add 10 to both sides}
1.5x² = 14 + 10
1.5x² = 24 {Divide both sides by 1.5}
1.5x²/1.5 = 24/1.5
x² = 16
x = ±4
Substitute x = 4 in (I)
y = 0.5 * 4² - 10
= 0.5*16 - 10
= 8- 10
y = -2
Substitute x = -4 in (I)
y = 0.5 * (-4)² - 10
= 0.5*16 - 10
= 8- 10
y = -2
