Y=mx+b
m=slope
b=yint
two points
cost=y
(4,5.5) and (7,7.75)
slope=(y2-y1)/(x2-x1)
slope=(7.75-5.5)/(7-4)=2.25/3=0.75
y=0.75x+b
find b
(4,5.5)
x=4
y=5.5
5.5=0.75(4)+b
5.5=3+b
minus 3 fromboth sides
2.5=b
y=0.75x+2.5
3 hours
y=0.75(3)+2.5
y=2.25+2.5
y=4.75
answer is D
Answer = $44
1. Divide $140 by 5/7. It will give us how much Kelvin had originally, which is $196
(I got 5/7 by doing 7/7 - 2/7)
2. Find 2/7 of 196 by multiplying them. This is 56....meaning that Kelvin gave James $56
3. Subtract 100 - 56 to find how much James had before this, which is $44.
Answer:
D
Step-by-step explanation:
the square root is between 14.1 and 14.2.
When the exercise asks to describe the likelihood of the event using the probabilities means that taking into account that the probabilities are numbers between 0 and 1, see if the events are likely or not to happen.
For a soft drink, which has a 0.80 probability is a likely event that could happen because it is greater to the middle (0.5) but is not so close to 1.
For a daily special, which has a 0.25 probability is more and unlikely event that could still happen but its not so common to.
For dessert, which has a probability of 0.5 probability is neither a likely nor unlike event because the probability is really close to the middle.
For appetizer, which has a probability of 0.06 probability is more an unlikely/impossible event because the probability is so small and close to 0 that it is not common to happen at all.
