Answer:
25
Step-by-step explanation:
ratio 5:6
6x = 5(30)
6x = 150
x = 25
Answer:
y = - 4.4
Step-by-step explanation:
Given that t varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = - 6.6 when x = 9.9 , that is
- 6.6 = 9.9k ( divide both sides by 9.9 )
k = 
= - 
y = - k ← equation of variation
When x = 6.6, then
y = - × 6.6 = - 2 × 2.2 = - 4.4
Answer:
It's descriptive.
Step-by-step explanation:
inferential statistic, means we are inferring based on a sample of our population. Many times we need to infer because the data we need to collect is too large, i.e. the population is too large e.g. the average age of high school students in the US. so we take a sample, a portion of this population and we calculate their mean age. If our sample is random enough, we can "infer" to a certain degree of accuracy the mean
But descriptive statistics, describes the data. They are numbers used to summarise and describe a data. 60% describes the data.
