Answer: 0.5

Step-by-step explanation:

Given :  The number of days varies directly with the number of chores in the given table.

The equation of direct variation is given by :-

y=kx, where k is the constant of variation.

For the first row , put x= 2 and y = 1 in the above equation , we get

1=k(2)\\\\\Rightarrow\ k=\dfrac{1}{2}=0.5

Therefore , the constant of variation : k=0.5

Y = kx....with k being the constant of variation
(2,1)...x = 2 and y = 1
sub and solve for k
1 = 2k
1/2 = k <=== constant of variation is : 1/2

Interquartile range = 3rd Quartile - 1st Quartile Class A: 89 - 66 = 23Class B: 94 - 79 = 15
IQR indicates the spread of the of the scores over the median. Class A has a spread that his more than 50% of the scores of Class B.
Hope this helps!!  :)
