Answer: 18°
Step-by-step explanation:
Complementary angles are any two angles whose sum is 90 degrees. Hence, if angles x and y are complimentary, we can say
x + y = 90°
Therefore, the complimentary angle of 72° is obtained by subtracting 72° from 90°
i.e 90° - 72° = 18°
Thus, the complimentary angle of 72° is 18°

Answer:
Cost of a package of celery = $20
Step-by-step explanation:
Let, x=carrots and y= celery.
So from the given data we get 2 equations
Equation 1]:-
------------(for 9 package carrot and 12 package celery)
Equation 2]:-
---------------(for 1 package carrot and 3 package celery)
After solving equation 2 we get,
------------------------(equation 3)
Now substituting equation 3 in equation 1,
∴
------------------(equation 4)
Therefore cost of a package of celery = $20
Answer:The relationship between the two variables is known as correlation. If the points are close to each other and making a straight line in the scatter plot, then two variables are said to have a high correlation. If the points are equally distributed in the scatter plot, the correlation is said to be low, or zero.
