Apsychologist would like to examine the effects of different testing methods on the final performance of college students. one group gets regular quizzes, one group gets three large exams, and the third group only gets a final exam. at the end of the course, the psychologist interviews each student to get a measure of the student’s overall knowledge of the material. quizzes exams final only 4 1 0 6 4 2 3 5 0 7 2 2 we want to know if these data indicate any significant differences among the three methods

if you're trying to figure out how much each ounce cost it would be 0.20

cents each ounce

its line 2 i just added the rest or else it wouldn't let me answer

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .
