Astudy showed that low-intensity shock therapy reduces pain levels in patients with lupus. during each session, electrodes were placed on the pain site indicated by the patient. pain reduction was measured through self-reporting after each session.

another study is being designed to examine whether low-intensity shock therapy also reduces pain in patients suffering from bulging disks in the thoracic region of the back. two hundred female patients are subjects in the new study.

part a: what is an appropriate design for the new study? include treatments used, method of treatment assignment, and variables that should be measured. (4 points)

part b: if the study consisted of 100 male and 100 female patients instead of 200 female patients, would you change the study design? if so, how would you modify your design? if not, why not? (4 points)

part c: could your design be double-blind? explain. (2 points)

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units

step-by-step explanation:

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.

step-by-step explanation:

x = 3 ± √(5+y)
