X+6=y
Y^2-x^2=84
So substitute.
Y^2-x^2=84
(X+6)^2-x^2=84
X^2+12x+36-x^2=84
12x+36=84
12x=48
X=4
So then use this value to find y by substituting.
X+6=y
4+6=y
10=y
Answer:
Probability that X <32 degrees
Convert this into percent by multiplying by 100
95.22% of days in February has minimum temperatures below freezing (32 degrees Upper F )
Step-by-step explanation:
Given that a city's mean minimum daily temperature in February is 22 degrees Upper F, with std deviation 6 degrees.
Let X be the minimum temperature in February
Then X is N(22,6)
To calculate percentage of days in February has minimum temperatures below freezing (32 degrees Upper F )
Probability that X <32 degrees
Convert this into percent by multiplying by 100
95.22% of days in February has minimum temperatures below freezing (32 degrees Upper F )

Slope: (y2-y1)/(x2-x1)
(-13-(-7)) = -6
-6/3 = -2
x - 3 = 3, x = 6
The solution: x = 6
