matrenka [14]

withdraw means subtract, deposit means add

152 withdraws 20 deposits 84

152 -20 + 84

152 - 20 + 84 = 132 + 84 = 216

Consider the solid obtained by rotating the region bounded by the given curves about the y-axis. X = 5 sqrt( y) text(, ) x = 0 t
kkurt [141]

Answer:

V = 200 π

Step-by-step explanation:

x = 5√y ,   x = 0 ,   y = 4

<u>Determine the volume of the solid V</u>

when x = 0  y = 0

we can calculate the volume of the solid by applying the washer method

V = π ₀⁴∫ [ 0 + ( 5√y )^2 ]  dy

   = π ₀⁴∫ [ 0 + ( 25(y) ) ]  dy

V  = π [ 0 + 25/2 ( y^2 ) ] ⁴₀

V = π [ 25/2 ( 16 ) ]

  = 200 π

The binary variable interaction regression
Vladimir [108]

Answer:

The correct option is D

Step-by-step explanation:

The correct option is D

The regression of binary variable interaction enables one of binary independent variables to be modified based on value of other binary variable.

In regression, whenever the impact of an independent variable on the dependent variable reforms, based on a value(s) of one or more than one independent variables, an interaction impact exists.
