Step-by-step explanation:
From the question we told that
The stem plots for American League is
Here the first column is the tens while each digit in the in the second column is the unit of the first column
For example row 3 means
40 , 43, 49
The sample size is n = 14
Generally the median is mathematically represented as
Here K is the i.e
From the stem plot the 7th term is 57
And
K is the i.e
From the stem plot the 8th term is 58
Thus the median is
=>
The stem plots for National League is
Generally the mean is mathematically evaluated as
The first ship travels (25 mi/h)*(2 h) = 50 mi.
The second ship travels (20 mi/n)*(2 h) = 40 mi.
The angle between their directions of travel is 120° -50° = 70°.
The law of cosines can be used to find the distance (d) between the ships.
d² = 50² + 40² - 2*50*40*cos(70°)
d² = 2500 +1600 -4000*cos(70°)
d² ≈ 2731.919
d ≈ √2731.919 ≈ 52.3 . . . . miles
At noon, the ships are about 52.3 miles apart.
The second ship travels (20 mi/n)*(2 h) = 40 mi.
The angle between their directions of travel is 120° -50° = 70°.
The law of cosines can be used to find the distance (d) between the ships.
d² = 50² + 40² - 2*50*40*cos(70°)
d² = 2500 +1600 -4000*cos(70°)
d² ≈ 2731.919
d ≈ √2731.919 ≈ 52.3 . . . . miles
At noon, the ships are about 52.3 miles apart.
