Answer:
x = 9 and y = 15
Step-by-step explanation:
An equilateral triangle, all sides and angles are congruent and each angle is equal 60 degrees
PQR is an equilateral triangle
So
PQ = QR = RP
Given:
PQ is 14y-59
QR is 9y+1
RP is 11y-23
Angle R is 7x-3
PQ = QR
Plug in
14y-59 = 9y+1
5y = 60
y = 15
Angle R is 7x-3, also <R = 60
So
7x - 3 = 60
7x = 63
x = 9
Answer
x = 9 and y = 15
The box plot that would confirm the inference that Linda made would have a minimum value of 20 and a maximum value of 40. Somewhere in the between is the mean. The box plot should have a confidence interval of 95% in order to have the inference valid.<span />
