(1 + 5 ) x 2 = 12 1 + [(5 x 2) – 2] = 10

1 + [5 x (2 – 2)] = 1 [1 + (5 x 2)] – 2 = 9

8 = 12 – [8 / (4 / 2)] 11 = 12 – [(8 / 4) / 2]

½ = [(12 – 8 ) / 4] / 2 20 = 6 x 4 – 4 x 5 ß----can’t figure it out …sorry

0 = 6 x (4 – 4) x 5 100 = [(6 x 4) – 4] x 5

24 = [14 –(8 -2)] x 3 0= (14 –8) – (2 x 3)

12 = [{14 – 8) - 2] x 3 12 = 14 – [8 - (2 x 3)]

The probability distribution was used along with statistical software to simulate 25 repetitions of the experiment (25 games).

Answer:

Hello here is the missing data to your question

x P(x)

0 0.167

1 0.3289

2 0.2801

3 0.149

4 0.0382

5 0.0368

The theoretical values are lower than the approximate values and the property illustrated is the mean and standard deviation

A) 1.6729

B) 1.234061

C) 1.84

D) 1.462874

Step-by-step explanation:

A) calculate the theoretical mean

theoretical mean (u) = summation of ; $x_{i}p(x_{i})$

= 0(0.167)+1(0.3289)+2(0.2801)+3(0.149)+4(0.0382)+5(0.0369)

= 1.6729

B) calculate the theoretical standard deviation

theoretical standard deviation = $\sqrt{variance}$ = $\sqrt{[summation of x_{i}^2 p(x_{i} ) ]-u^2}$

= $\sqrt{[0+0.3289+1.1204+1.341+0.6112+0.92]-(2.798594)}$

= 1.234061

C) calculate the approximate mean

the generated data used for calculation is added below

mean (x) = $\frac{summation of (x_{i}) }{n}$ = $\frac{1+2...+2+1}{25}$ = 46/25 = 1.84

D) calculate the approximate standard deviation

std = $\sqrt{variance}$

= $\sqrt{\frac{summation of( x_{i}-x )^2}{n-1} }$

= $\sqrt{2.14}$ = 1.462874

The point P(7, −3) lies on the curve y = 3/(6 − x). (a) If Q is the point (x, 3/(6 − x)), use your calculator to find the slope

AleksandrR [38]

Answer:

The right answer is "3.33333".

Step-by-step explanation:

The given points in the question are:

$P=(7,-3) = (x_1,y_1)$

$Q=(x,\frac{3}{6-x} )=(x_2,y_2)$

Now,

The slope of PQ will be:

= $\frac{y_2-y_1}{x_2-x_1}$

By putting the values, we get

= $\frac{\frac{3}{6-x}+3 }{x-7}$

= $\frac{3+18-3x}{(6-x)(x-7)}$

= $\frac{21-3x}{(6-x)(x-7)}$

= $\frac{3(x-7)}{(6-x)(x-7)}$

= $\frac{3}{x-6}$

hence,

x = 6.9

it's slope will be:

= $3.33333$
