Answer:
A. The population in the CPS survey are all US households.
B. The population in the CES survey are all the non-farm businesses and government agencies.
Step-by-step explanation:
A sample is the number of people from a whole population who actually participated in a survey. The population is the entire group of people whom the survey is meant to study. The sample is an off shoot of the population.
In the given question, the Current Population Survey is a study on the entire US households. Since every household cannot be interviewed because of the large population, a sample of 60,000 households is used. The whole households in the United States thus form the population under study.
For the Current Employment Statistics survey, the goal is to understand employment statistics in all the non-farm businesses and government agencies. This is the population. Since the entire population cannot be studied, a sample of 140,000 is used.
Answer:
the angle of inclination of the hill is 46.56°
Step-by-step explanation:
Given the data in the question;
Just as illustrated in the diagram below
so to find the angle of inclination of the hill;
sinA/30 = sinB/125
since angle BAC is 8°
we substitute
sin8°/30 = sinB/125
sinB = ( sin8°/30 ) × 125
B = sin⁻¹ ( ( sin8°/30 ) × 125 )
B = sin⁻¹ ( 0.004639 × 125 )
B = 35.44°
so since the some of a the angles of a triangle is 180;
A + B + C = 180
8° + 35.44° + C = 180
C = 180 - ( 8° + 35.44° )
C = 136.56°
Hence, Angle of inclination x will be;
x = 136.56° - 90°
x = 46.56°
Therefore, the angle of inclination of the hill is 46.56°
The answer to the equation. is 2
Answer:
12r-32
Step-by-step explanation:
Distribute the 4 between the different numbers.
3r * 4 = 12r and 8 * 4 = 32
So...you end up with 12r-32
