2. What factors brought about the end of communism in Eastern Europe and the Soviet Union?

bezimeni [28]

The Soviet Union experienced a crisis due to economic waste. The socio-cultural crisis in the USSR occurred because of class division, the low quality of people's lives, and the government was not allowed to develop people's creativity. In particular, the system named Glasnost and Perestroika which was proclaimed by President Gorbachev was the trigger for the explosion of social revolutions in Eastern European countries.

Please show steps and explain

AlexFokin [52]

Answer:

$\frac{n-6}{3n} = \frac{n-5}{3n+1} \\\\\frac{n-6}{3n} - \frac{n-5}{3n+1} = 0\\\\\frac{(3n+1)(n-6)-3n(n-5)}{3n(3n+1)} = 0\\\\(3n+1)(n-6)-3n(n-5) = 0\\\\3n^2-18n+n-6-3n^2+15n=0\\\\3n^2-3n^2-18n+n+15n-6=0\\\\-2n-6=0\\\\2n+6=0\\\\2n=-6\\\\n=-3$

You can solve this equation by applying the zero product rule.

Firstly, you equate the expression to 0 in order to combine both fractions into one. As shown in Step 2, you find the LCM of both fractions and multiply accordingly. In this case, the LCM of both fractions is 3n(3n+1). Hence you cross multiply.

Next, you eliminate the denominator in order to solve the equation more conveniently. As you multiply the fraction by the denominator on the LHS, you do that to the RHS as well to maintain balance. 0×3n(3n+1)=0, hence Step 3.

Then, you expand the parentheses using the distributive law of multiplication, resulting in a quadratic equation.

Lastly, you solve the quadratic equation.

The answer is n=-3

The equation of the normal line

Sedaia [141]

Answer:

D. y = 1/2x + 3/2

Explanation:

You probably already know the point slope equation:

y = m(x - x₀) + y₀

All you need is the slope and the (x₀, y₀).

The (x₀, y₀) could be solved by plugging in the given x=-1 value into the function.

m, the slope, is the same as a derivative; ie. a derivative is a slope.

So solve for the derivative and find the slope at x=-1.

Plug into point slope equation and simplify.

Electric vehicles make up a very small proportion of the overall car market, but by how much has that proportion increased? Inde

Minchanka [31]

Given Information:

The proportion of electric cars sold in 2012 = p₁ = 0.1%

The proportion of electric cars sold in 2016 = p₂ = 0.5%

Sample size of electric cars in 2012 = n₁ = 10,000

Sample size of electric cars in 2016 = n₂ = 20,000

Confidence level = 95%

Required Information:

Change in the proportion of electric cars sold from 2012 to 2016 = ?

Answer:

Change in the proportion of electric cars sold from 2012 to 2016 = (0.284%, 0.516%)

Step-by-step explanation:

The change in the mean is given by

$\mu = p_2 - p_1\\\\\mu = 0.005 -0.001\\\\\mu = 0.004\\\\$

The change in standard error is given by

$SE = z\cdot\sqrt{\frac{p_1(1 - p_1)}{n_1} + \frac{p_2(1 - p_2)}{n_2} }$

Where z is the value of z-score corresponding to 95% confidence level.

$z_{\alpha/2} = 1 - 0.95 = 0.05/2 = 0.025\\\\z_{0.025} = 1.96\\\\$

$SE = 1.96\cdot\sqrt{\frac{0.001(1 - 0.001)}{10,000} + \frac{0.005(1 - 0.005)}{20,000} } \\\\SE = 1.96\cdot 0.00059\\\\SE = 0.00116\\\\$

The change in the proportion of electric cars is

$\mu \pm SE \\\\0.004\pm 0.00116 \\\\(0.004-0.00116) \: and \: (0.004-0.00116)\\\\(0.00284, \: 0.00516)\\\\(0.284\%, \: 0.516\%)$

Therefore, we are 95% confident that the change in the proportion of electric cars sold from 2012 to 2016 is between (0.284%, 0.516%)
