Answer:
7.6997
Explanation:
Given :
X : ____7 ____ 15 ____ 28
P(X) __0.2 ___0.49 ____?
ΣP(x) = 1
0.2 + 0.49 + a = 1
a = 1 - 0.69
a = 0.31
Standard deviation = sqrt(Variance(x))
Variance = Var(X) = Σx²p(x) - E(x)²
E(x) = Σx*p(x) = (7*0.2) + (15*0.49) + (28*0.31) =
E(x) = 17.43
Σx²p(x) = (7^2 * 0.2) + (15^2 * 0.49) + (28^2 * 0.31) = 363.09
Var(X) = Σx²p(x) - E(x)²
Var(X) = 363.09 - 17.43^2
Var(X) = 363.09 - 303.8049
Var(X) = 59.2851
Standard deviation = sqrt(59.2851)
Standard deviation = 7.6996818
= 7.6997

Describe the relationship between the social history of Texas and the political characteristics of the state’s diverse population.
Please help i at least need 3 sentences long!
The correct answer to this open question is the following.
Although there are no options attached we can say the following.
The relationship between the social history of Texas and the political characteristics of the state’s diverse population. can be traced back to when the territory of Texas belonged to the Mexican government. Then, we can identify the times of Stephen F. Austin trying to colonize the Texas territory, negotiating with the Mexican authorities to grant the authorization to bring Anglo people to Texas. Then, fateful episodes such as the Alamo, and later, the victory of the Texan army in the Battle of San Jacinto, in Galveston. After being a Republic, Texas was annexed to the Union but there has always been a mixture of the Anglo culture with the Mexican culture even today. That intermingling of belief systems, culture, and traditions is one of the notorious things that characterizes Texas, especially cities such as San Antonio, El Paso, Houston, and Dallas.
