Answer:
An expected height of 160.6 centimeters when the femur has a length of 40 centimeters.
Step-by-step explanation:
The line of best fit makes a prediction. In other words, it tells us what height to expect for any given femur length.
x represents femur length and y represents height, so the y-value on the line when x=40x is the expected height when the femur length is 40 cm.
Work only with the second equation at the beginning. Solve for x for it.
7x - 2x = 3 Combine the left hand side.
5x = 3 Divide by 5
5x/5 = 3/5 Do the division
x = 3/5 = 0.6
==============
Now work with the top equation.
3(0.6) + 5y = 13 Multiply on the left.
1.8 + 5y = 13 Subtract 1.8 from both sides.
1.8 - 1.8 + 5y = 13 - 1.8 Do the subtraction
5y = 11.2 Divide by 5
5y/5 = 11.2/5
y = 2.24 Answer

Step-by-step explanation:
Use the compound-interest formula:
Where:
FV=Future value or the ending amount
PV=Present value or the initial amount=750
n=Number of compoundings in any one year=2
t=Total number of years=4
r=interest rate=0.0425
Now, replacing the data in the equation:
