Answer:
c. x = 7-t; y = -1/(t -7)
Step-by-step explanation:
To find the parametric equation for x, use the equation for t and solve for x.
t = 7-x
x = 7 -t . . . . . . add x-t to both sides
__
To find the parametric equation for y, substitute the equation for x.
y = 1/x
y = 1/(7-t)
To make this match the available choices, we need to multiply numerator and denominator by -1.
y = -1/(t -7)
The parametric equations are ...
x = 7 -t; y = -1/(t -7) . . . . . . matches choice C

Answer: Plot 1
Step-by-step explanation:
#1 Find the median of the whole set
- since there are 31 data, it is odd, we just need to find the 16th data which is 73.
- the median is 73
#2 Find the median of Less than Q2
- since there are 15 data, it is odd, we just need to find the 8th data which is 64
- the median is 64
#3 Find the median of more than Q2
- since there are 15 data, it is odd, we just need to find the 8th data which is 84
- the median is 84.
