Answer:
x ≈ 6.36
Step-by-step explanation:
Using the Sine Rule in Δ GHI
= 
, substitute values
= 
( cross- multiply )
x sin127° = 21 sin14° ( divide both sides by sin127° )
x = 
≈ 6.36 ( to the nearest hundredth )
Answer:
The given statement describe inferential statistics.
Step-by-step explanation:
Descriptive Statistic:
- It helps us to summarize a given data set.
- It could describe the entire population or a sample from the population.
- There are two types of descriptive measures: measures of central tendency and measures of variability
- Central Tendency: Mean, mode, Median
- Measure of Viability: Standard Deviation, Variance, Range, Interquartile range
Inferential Statistic:
- It s the process of estimating population parameter with the help of a sample from the population.
- A random sample from the population is used to describe the population with the help of sample statistic.
Given Scenario:
"Based on a sample of 170 truck drivers, there is evidence to indicate that, on average, independent truck drivers earn more than company-hired truck drivers."
Thus, this is an example of a inferential statistics as a sample was used to estimate the population.
Here,
Sample:
Sample of 170 truck drivers
Population:
All truck drivers.
With the help of a sample, we approximated the population, thus, this statement describe inferential statistics.

Answer:
- Proportional, y = 3 times x
- Not proportional
Step-by-step explanation:
The graph shows a proportional relationship if it is a straight line that goes through the origin (0, 0). The constant of proportionality can be found by looking for the y-value when x = 1.
1) The graph is a straight line that goes through the origin. The relationship is proportional. When x=1, y=3, so ...
y = 3 times x
__
2) The graph does not go through the origin. The relationship is Not Proportional.
Answer:
The answer is 'No Solution'
