Thus. If p is true and q is true, then ~ p ~ q is NEVER true.
Step-by-step explanation:
We know that '~' takes the truth value of the original statement then output the exact opposite of its truth.
Given that
if p and q us true.Let us check what would be the output of ~ p ~ q
Let us form the tabel
p q ~p ~ q ~ p ~ q
T T F F F
Thus. If p is true and q is true, then ~ p ~ q is NEVER true.

a. Write a function that models the number of golf carts repaired as a function of the number of days in the month of February:
y=(1/3)x
b. What is the meaning of the slope as a rate of change for this line of best fit?
For each three days of the month of february the number of golf carts repaired was 1; that means each three days of the month of february was repaired one golf cart.
Step-by-step explanation:
Let:
x: Day of the month
y: Number of golf carts repaired
a. Write a function that models the number of golf carts repaired as a function of the number of days in the month of February.
Taking two points of the right line, for example:
P1=(0,0)=(x1,y1)→x1=0, y1=0
P2=(3,1)=(x2,y2)→x2=3, y2=1
Slope: m=(y2-y1)/(x2-x1)
Replacing the known values:
m=(1-0)/(3-0)
m=1/3
Equation of the right line, using the form point-slope:
y-y1=m(x-x1)
Replacing the known values:
y-0=(1/3)(x-0)
y=(1/3)x
