Correct amswer is 4 whole pieces
There is a bias in this sampling method.
The interviewer only interviews people exiting a local restaurant, which means it's more likely for the people to go out to eat regularly.
If he wanted an interview with no bias, he should go out and interview random people on the street, not in front of any business.
Ok so find the legnth of one side
if we drwa the diagonal, we cut the squre into 2 right triangles with legs equal measure
pythagorean theorem
for a right triangle with legs legnth a and b, and hypotnuse legnth c
a^2+b^2=c^2
since square, a=b
a^2+a^2=c^2
2a^2=c^2
diagonal=hypotnuse=32
2a^2=32^2
2a^2=1024
divide both sides by 2
a^2=512
sqrt both sides
a=16√2
the perimiter is 4 times one side
side=a=16√2
4 times 16√2=64√2
permiter is 64√2 cm
AC is 2x+1
CB is 3x-4
AB= 2x+1+3x-4
Answer:
x=2/3
Step-by-step explanation:
-3x+4=2
-3x=-2
x=2/3
