Answer: The second graph
In all but the 3 graphs, the data is perfectly symmetrical. This means that the mean and the median would be the same.
However, in the second graph the data is skewed to the right. This means that the mean would also be skewed to the right due to the larger scores there. Using the median in this case would give a clearer picture of the data.
Answer:
The rocket hits the gorund after approximately 10.71 seconds.
Step-by-step explanation:
The height of the rocket <em>y</em> in feet <em>x</em> seconds after launch is given by the equation:
And we want to find the time in which the rocket will hit the ground.
When it hits the ground, its height above ground will be 0. Hence, we can let <em>y</em> = 0 and solve for <em>x: </em>
<em />
<em />
We can use the quadratic formula:
In this case, <em>a</em> = -16, <em>b</em> = 165, and <em>c </em>= 69.
Substitute:
Evaluate:
Hence, our solutions are:
Since time cannot be negative, we can ignore the first answer.
So, the rocket hits the gorund after approximately 10.71 seconds.
Based on the interior angle measure at Bermuda, the interior angle measure at San Juan, the value of y can be found to be 61.8°
<h3>What is the value of y?</h3>
The interior angle measures at Bermuda, San Juan, and Fort Lauderdale take the shape of a triangle so they will add up to the total interior triangle measure of 180°.
y is also the angle at For Lauderdale so the value of y is:
y + (y - 7.5) + 63.9 = 180°
Solving gives:
y + y - 7.5 + 63.9 = 180
2y = 180 - 63.9 + 7.5
2y = 123.6
y = 123.6/2
= 61.8°
