With simple interest, you only earn 5.5% of the original $150 each year.
So after 4 years, your money will earn (5.5% x 4) = 22% of the original $150 .
22% of $150
= 0.22 x $150
= $33 .

Answer:
Step-by-step explanation:
we know that
The height of Justin’s rocket is modeled by the equation
This is the equation of a vertical parabola open downward
The vertex is a maximum
where
The coefficient of t^2 represent the acceleration
The coefficient of t represent the initial velocity
The constant of the equation represent the initial height
Remember that
Elena launched his rocket from the same position, but with an initial velocity double that of Justin’s
so
Now the initial velocity is
substitute
The height of Elena’s rocket is the equation
275+180+120=575 or <span>275+180+120=120+180+250 (commutitative property of addition)</span>
Answer:
Now that his car is 5 years old, he would like to know whether the variability of gas mileage has changed. He recorded the gas mileage from his last eight fill-ups; these are listed here. Conduct a test at a 10% significance level to infer whether the variability has changed.
