Answer:
A lurking variable is a variable that has an important effect on the relationship among the variables in the study, but is not one of the explanatory variables studied. Two variables are confounded when their effects on a response variable cannot be distinguished from each other.
Answer: The answer is in the first image.
Explanation: The explanation is in the second image.
Answer:
Ã=7/6
Step-by-step explanation:
<em>2/3(x -6) -y </em>
<h3><em>put the value of x= 9 and y=5/6 </em></h3>
=2/3(9-6)-5/6
=2/3×3-5/6
=2/1-5/6
=12-5/6
=7/6

Answer:
502 m²
Step-by-step explanation:
We require to find b before calculating the surface area.
The volume (V) of a cuboid is calculated as
V = lbh ( l is length, b is breadth and h is height )
Here V = 510, l = b, b = 10 and h = 3, thus
b × 10 × 3 = 510
30b = 510 ( divide both sides by 30 )
b = 17
--------------------------
The opposite faces of a cuboid are congruent, thus
top/bottom area = 2(17 × 10) = 2 × 170 = 340 m²
front/back area = 2(17 × 3) = 2 × 51 = 102 m²
sides area = 2(10 × 3) = 2 × 30 = 60 m²
Surface area = 340 + 102 + 60 = 502 m²
So, what you want to do here is subtract the ice cream sold on the weekend from the ice cream that was sold during the rest of the week.
He sold 19 on Saturday and 27 on Sunday, so these numbers need to be subracted from your total for the week.
(Total Sold) - [(Amount sold Saturday) + (Amount sold Sunday)] = (Amount sold on weekdays)
153 - (19 + 27) = X
153 - 46 = X
107 = X
