A cell phone manufacturer chose 200 people at random and asked them whether they would purchase the newest model for $300. The manufacturer repeated this survey using the same method three more times.Do any of the surveys appear to be biased?

Would purchase new model for $300? Survey
1 2 3 4
Yes 127 131 128 133
No 73 69 72 66

A.
Yes, because the results from Survey 1 differ the most from the other surveys’ results.

B.
Yes, because the results from Survey 4 differ the most from the other surveys’ results.

C.
No, because the sampling methods are all different but have about the same results.

D.
No, because all four surveys have about the same number of people saying “yes” and about the same number of people saying “no.”

If x/yis rational, must x and y each be rational?
A) Yes; because the quotient of rationals is rational.
B) No; because x and y could have a common irrational factor.
C) No; because the quotient of irrationals is always irrational.
D) Yes; because x and y must be integers, and integers are rational.

Answers

The answer is B.

Consider the fraction $(6 √(5) )/(√(5))$ .

Both the numerator and denominator, when by themselves, are irrational.

However, when they are divided, they result in the rational number $(6 √(5) )/(√(5))=\boxed{6}$ .

When $p,q$ have the same irrational factor, the irrational factor will be cancelled from the fraction and (possibly) leave a rational number.

Answer: The answer is B.

Step-by-step explanation:

No; because x and y could have a common irrational factor.

Write the standard equation for the circle center left parenthesis negative 6 comma 7 right parenthesis, r = 9.A. left parenthesis x minus 6 right parenthesis squared plus left parenthesis y plus 7 right parenthesis squared equals 9
B. left parenthesis x minus 7 right parenthesis squared plus left parenthesis y plus 6 right parenthesis squared equals 81
C. left parenthesis x plus 6 right parenthesis squared plus left parenthesis y minus 7 right parenthesis squared equals 81
D. left parenthesis x plus 6 right parenthesis squared plus left parenthesis y minus 7 right parenthesis squared equals 9

Answers

Answer:

Step-by-step explanation:

The standard form equation for a circle is

$(x-h)^2+(y-k)^2=r^2$

where h and k are the coordinates of the center. Our center is given as (-6,7) and the radius is given as 9, so that information fits into our standard form like this:

$(x-(-6))^2+(y-7)^2=9^2$ and simplified, it looks like this:

$(x+6)^2+(y-7)^2=81$

That's choice C
