Answer:
x = (-5,10)
Step-by-step explanation:
Option B) 37.12 is the right answer
Step-by-step explanation:
It is given that the qudrilateral is a rectangle which means that opposite sides wil be equal and all interior angles will be 90 degrees
So
PS = 17
PQ = SR = 33
The diagonal PR will form a right-angles triangle with PR being the hypotenuse
So,
Base = SR = 33
Perpendicular = PS = 17
Hypotenuse = PR = ?
The Pythagoras theorem will be used to find the length of PR
So,

Taking square root on both sides

Rounding off to nearest 100th
PR = 37.12
Hence,
Option B) 37.12 is the right answer

Answer: A. 6.5
Step-by-step explanation:
Here, the given set = { 15, 19 3, 12, 17, 2, 2, 8}
Mean, 
Number of elements, n = 8

Thus, the standard deviation, 
⇒ Option A is correct.
74% * x = 128
x=128/74%
x=172.97 (nearest hundredth)
