This is a bit are to read so I'm unable to solve
Answer:
11
Step-by-step explanation:
If you notice the x values 5, 7, 9, x you'll see thy are going up by adding 2.
do 9 + 2 = 11
Answer:
The predicted value of the year 18 is 107
Step-by-step explanation:
create a scatter plot for year and mean variables.
(<em>i have done that with Microsoft excel check the attachment from 1-3)</em>
Least square regression equation:
y = 9.3187x - 61.121
Predicted value of the lean 18
y = 9.3187 x (18) - 61.121
y = 107
The predicted value of the year 18 is 107
Problems of this sort are frequently found in physics. If you study calculus or physics you'll learn how to create the equation representing the velocity of an object in flight.
Here, you don't need to calculate velocity, but rather time. Start with this equation:
v = v0 + a t^2, where v is the velocity at time t, v0 is the initial velocity, a is the acceleration due to gravity (denoted by g instead of a), and t is the elapsed time.
You are told that v0 is 15 ft/sec. Set v = to 0, as the ball stops moving for the tiniest instant at the top of its trajectory. Use g = - 32 ft (per second squared).
Then 0 = 15 ft/sec - 32 [ft/(seconds squared)] t.
Solve this for t. This is the time required for the ball to come to a complete stop at the top of its trajectory.
Finally, multiply this time by 2, since the ball begins to fall and returns to its original height.
