the coordinates of the vertices of quadrilateral rstu are r(−4, 1), s(4, −1), t(3, −6), and u(−5, −4). which statement correctly describes whether quadrilateral rstu is a rectangle?

which statement correctly describes whether quadrilateral rstu is a rectangle?

quadrilateral rstu is not a rectangle because it has no right angles.

quadrilateral rstu is a rectangle because it has four right angles.

quadrilateral rstu is not a rectangle because it has only two right angles.

quadrilateral rstu is not a rectangle because it has only one right angle.

here you go!

sorry if it is late, but this if for others with the same question so give the person above brainlist:

Step-by-step explanation:

Number of members chosen by Helena in her homeroom = 5

Mean number of tickets = 16

So, total candidates who had purchased ticket = 16 × 5= 80

Now, number of candidates chosen randomly = 10

So, total candidates who had purchased ticket = 22.5 × 10=225

No, one sample can't be a better representation by choosing randomly a group of members.

In Sample 1 , we are considering only 5 drama numbers.

And In Sample 2, we are considering 10 random samples among 75 members.

The mean in two cases varies by (22.5-16=6.5) which is large because we are considering number of tickets sold by members of club.

It would have been better if she has taken more than 3 random samples of 15  students ,among 75 students, then she would have got appropriate mean or value near the mean.
