X+y=2(x-y)
x+y=2x-2y
3y=x
x-2y=2
then,substitute
(3y)-2y=2
y=2
so,x=3(2)
x=6
x the largest
y the smallest
Answer:
115
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = 7 - 1 = 13 - 7 = 19 - 13 = 25 - 19 = 6
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 1 and d = 6 , thus
a₂₀ = 1 + (19 × 6) = 1 + 114 = 115
Answer:
The data is quantitative
Data is discrete
The highest level is Ordinal
Step-by-step explanation:
Data is of quantitative type when it allows us to measure, in a numerical and objective way, the differences between different observations. Eventhough the supervisor uses words ( fair, poor etc) he can assign numerical values and measure differences between observations that has sense. Qualitative data refers to opinions, stories, interviews, images or data that cannot be interpreted numerically and has subjective interpretations depending in researcher.
Data is discrete because the variable measured: evaluation rating, can only takes certain specific values (1 to 5) A continuous variable, such as height can take many values in a ratio or real line,
Nominal data refers to variables that takes two possible values - the presence and absence of a characteristic, like being or not being a minor. Ordinal variables are variable which are discrete but the value of the variable allows to classify data in a specific order. This is the case of the rating scale. Interval variables are are ones that have specific low levels and high levels like age ranges.
