2 answers:
Answer:
Mean = 11027.2
Median = 12050
Mode = no mode
Step-by-step explanation:
Gina drove about 12,200 miles the first year
She drove about 6,211 miles the second year
She drove about 12,050 the third year
She drove about 11,350 the fourth year
She drove about 13,325 the fifth year
Arrange the data in ascending order :
6,211 , 11,350 , 12,050 , 12,200 , 13,325
Mean :
:
:
Median: it is the mid value .
So, mid value is 12050
So, median = 12050.
Mode: The number which appears most often in a set of numbers.
Mode = there is no mode
Hence Mean = 11027.2 , Median = 12050 and Mode = no mode

Answer:
The minimum value for is
.
Step-by-step explanation:
Given function is
We need to find the maximum value or the minimum value for the function.
Now, differentiate w.r.t
.
Now, we will equate to find critical point.
Plug this critical point in to the function we get,
Also, which is positive, We have minimum value.
So, the minimum value for is
.

The answer is below
Step-by-step explanation:
The standard form of the equation of an ellipse with major axis on the y axis is given as:
Where (h, k) is the center of the ellipse, (h, k ± a) is the major axis, (h ± b, k) is the minor axis, (h, k ± c) is the foci and c² = a² - b²
Since the minor axis is at (37,0) and (-37,0), hence k = 0, h = 0 and b = 37
Also, the foci is at (0,5) and (0, -5), therefore c = 5
Using c² = a² - b²:
5² = a² - 37²
a² = 37² + 5² = 1369 + 25
a² = 1394
Therefore the equation of the ellipse is:
