In a local university, 49% of the students say that they get less than recomended eight hours of sleep per night. In a group of 3300 student, how many would you expect get eight or more hours sleep per night students get eight or more hours of sleep per night (TYPE A WHOLE NUMBER)

One thousand six hundred and eighty - three students (1,683)

Step-by-step explanation: 49% of 3300 is 1,617 . If 49% don't get enough sleep then then question is indirectly asking for the exact amount of that particular 51%

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
