Answer:
A D E
Step-by-step explanation:
A. In the second problem, the first fraction is less than the second fraction.
D. If you subtract a lesser number from a greater number, the answer is positive.
E. If you subtract a greater number from a lesser number, the answer is negative.
Step-by-step explanation:
Area of the rectangle = 9×6 = 54 m²
Area of the path is also 54 m²
so total area of the bigger rectangle is 54+54 = 108 m²
now the ratio of length to width is 9:6 or, 3:2
so, for 108 m²
(3x)(2x) = 108
6x²=108
x²=18
x=3√2
So length = 3x = 9√2 and width = 2x = 6√2
The first scatter plot does not have a zero correlation.
Option(a) is correct.
A statistic called correlation gauges how much two variables change in connection to one another.
Correlation quantifies correlation but cannot determine whether x causes y or vice versa, or whether a third component is responsible for the association.
A scatterplot may make it easier to spot correlation, particularly when the variables have a non-linear but nevertheless significant association.
Zero means there is no correlation between the two variables under comparison.
A 0 correlation indicates that there is no relationship between the two variables according to the correlation statistic. This merely indicates that there isn't a linear relationship, not that there isn't any link at all. The first scatter plot does not represent a linear relationship, thus, it has zero correlation.

Answer:
Step-by-step explanation:
we are given a right angle triangle
we want to figure out x i.e hypotenuse
in order to do so we can consider trigonometry i.e <u>sin </u>
remember that,
given that,theta=21° and opp=17 and hypo=x
Thus substitute:
cross multiplication:
divide both sides by sin21°:
By using calculator we acquire:
