Answer:

How does economic inequality contribute to political polarization?

Income inequality has been typically examined from an economic perspective. However, it becomes more and more politicized in recent decades, causing a wide range of detrimental political consequences. Growing inequality could undermine social mobility, induce violent conflicts, and generate political tensions.

48 = 2(2w)+(4+2w)2. What Is w
crimeas [40]

Hello from MrBillDoesMath!

Answer:

w = 5



Discussion:

48 = 2 (2w) + (4 + 2w)2       =>

48 = 4w        + 4*2 + (2w)*2  =>

48 = 4w       +  8    + 4w        =>   as 4w + 4w = 8w

48 =  8w      +  8                    => subtracting 8 from each side

48 - 8 = 8w                            => divide both sides by 8

(48 -8 )/8 = w                        =>

40/8 = w                                =>

w = 5                                      =>


Check:  2(10) + ( 4 + 2*5)*2 = 20 + 14*2 = 20 + 28 = 48




Thank you,

If students’ scores were normally distributed and the mean was 200 with a standard deviation of 40, then what is the probability
Sonja [21]

Answer:

  84%

Step-by-step explanation:

The empirical rule tells you that 68% of the standard normal distribution is within 1 standard deviation of the mean. The distribution is symmetrical, so the amount in the lower tail is (1 -68%)/2 = 16%.

Since the number you're interested in, 240, is one standard deviation above the mean (200 +40), the percentage of interest is the sum of the area of the central part of the distribution along with the lower tail:

  68% + 16% = 84%.
