Answer:
You will likely need to actually measure a few people for parts 1 and 2, but the statement in part 2 should be something like "The length of the forearm of one person will be very similar to the length of their foot" or "As the length of the forearm increases, the length of the foot will increase in similar amounts".
Since the equation in pt.3 is y = 0.860x + 3.302, if x=17, then 0.860(17) + 3.302=17.922
The next question is dependant on pt.1
The data from pt.1 should be somewhat similar to the data you collected, the values between them are different because of the allowed error margin between the two.
The data can be made into a function using the "line of best fit". The equation in part A represents a function because there are no two points where two y coordinates are on the exact same x coordinate.
Step-by-step explanation:
Number of hours on video games and test scores? Negative correlation (more hours playing less hours studying)
speed of a car and minimum stopping distance? Positive correlation (the higher the speed the bigger the stopping distance)
average running speed and total race time? Negative correlation (higher speed less time)
adult’s head
circumference and age? Not correlation
outside temperature and amount of a heating bill? Negative correlation (higher temperature less heating used)
Answer:
5.27
Step-by-step explanation:
Step 1 : 527

Place the numbers and line them up with the X axis
When m and n are multiplied, you get the c value of the quadratic.
This is also known as the y intercept, which is a constant.
Final answer: A
