Answer:
1.75 usd.
Step-by-step explanation:
I made the graphic to guide me. Th formula of the function that represents the problem is:
We choose two pairs, for example (2,3.5) and (4,7) and calculate the slope:
m=
And we calculate the equation with the slope and one pair:
(y-7)=1.75(x-4)
y-7=1.75x-7
y=1.75x-7+7
y=1.75x.
Then, for x=1, this is one pen the price (the y value) is
y=1.75(1)=1.75, yu can see also the aproximation of the result with the graphic.
Answer:
a)
b)
c)
Step-by-step explanation:
a)
Rolling a number greater than 3 means you can roll a 4, 5, or 6, which contains rolling a 6. So, the probability is
b)
Rolling a number less than 5 means you can roll a 1, 2, 3, or 4, but because you could also roll an even number, so you could also roll a 6.
So, the probability is
c)
Rolling a 4 or an odd number means you can roll a 1, 3, 5, or 4. So, the probability is
