The correct answer for this question is this one: "b. increased prices." <span>The small increase in global oil production coupled with an increased demand for those resources leads to increase in prices.
</span>
Here are the following choices.
<span>a. lack of modern energy sources
b. increased prices
c. decreased competition
d. decreased prices</span>
The correct answer to this open question is the following.
Although there are no options attached we can say the following.
The group that most of the Americans living on the frontier supported was the Cowboys.
Yes, at the end of the 1800s in the frontier region, Cowboys made a name by themselves. Indeed, they became one of the symbols of the West, almost as the ideal heroic man of that time.
The very first cowboys started in México under the Spanish name of "vaqueros." They worked introducing cattle to the Mexican territory. Then, the American cowboy, not only whites but African Americans too. They worked for hours under harsh weather conditions, being hot conditions in summer and cold conditions in winter, and they really did not receive good salaries for the job they did.

0.146
Explanation:
Cohen's d= (mean of experimnetal group- mean of control group)/ Standard deviation
Cohen's d= (8-7.4)/4
= 0.146
Answer:
502.51 kg/m^3
Explanation:
Upthrust on object in water is 40 - 20 = 20 N
Upthrust is equal to the buoyancy forces given as
B = pgv
p is density of water 1000 kg/m^3
g = acceleration due to gravity 9.81 m/s^2
v is the volume of liquid displaced.
Therefore
B = 1000 x 9.81 x v
20 = 9810v
v = 2.038x10^-3 m^3
For Upthrust in unknown liquid, we have 40 - 30 = 10 N
Bouyancy force for the liquid will be
B = P x 9.81 x 2.038x10^-3
NB- the same volume of fluid will be displaced i.e 2.038x10^-3 m^3
Equating we have
10 = P x 9.81 x 2.038x10^-3
10 = 0.0199p
p = 10/0.0199 = 502.51 kg/m^3
