Answer:
40 miles
Step-by-step explanation:
let distance be d and time be t
Since d varies directly with t, then the equation relating them is
d = kt ← k is the constant of variation
To find k use the condition d = 75 when t = 3
k = 
= 
= 25
d = 25t ← equation of variation
when t = 1.6, then
d = 25 × 1.6 = 40 miles
Answer:
d
Step-by-step explanation:
we get that the slope is:
so the answer is -3
Answer:
Descriptive statistic, Inferential statistic
Step-by-step explanation:
Descriptive Statistic:
- The process of summarizing a data to get insight about the data.
- it consist of measure of central tendency and measure of spread.
- It can be about the entire population or a sample of the population.
- It helps to understand the feature of the data
Inferential statistic:
- It is the method of making generalizations about the entire population based on the sample.
- It help us to make prediction about the population parameter with the help of sample statistic.
- This is done with the help of estimation and hypothesis testing.
Thus, the correct answer is:
Descriptive statistics consists of organizing and summarizing information collected, while inferential statistics uses methods that generalize results obtained from a sample to the population and measure the reliability of the results.
