A trail around a river is 3 1/4 miles long. What is the length, in feet, of the trail?

bezimeni [28]

Answer: 17160 feet

Step-by-step explanation:

We know that 5280 feet = 1 mile

So all we have to do is multiply 3 1/4 by 5280

Let's split the 3 and 1/4 up to make the multiplication easier

3×5280=15840

$\frac{1}{4}$ ×5280= $\frac{5280}{4} =1320$

Now add them together

15840+1320=17160

Answer:a

$m = 57.5$

$\= x = 50.14$

Step-by-step explanation:

From the question we told that

The stem plots for American League is

$2\\3\ \ \ \ \ 5\\4 \ \ \ \ \ 0\ 3 \ 9\\5 \ \ \ \ \ 1\ 4\ 7\ 8\ 8\\6 \ \ \ \ \ 4\ 8\ 8\\7 \ \ \ \ \ 5\ 7$

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

$m = \frac{ K + Z}{2}$

Here K is the $(\frac{n}{2}) th \ term \ in \ the \ data \ given$ i.e $\frac{14}{2} = 7th \ term$

From the stem plot the 7th term is 57

And

K is the $(\frac{n}{2} + 1) th \ term \ in \ the \ data \ given$ i.e $\frac{14}{2} + 1 = 8th \ term$

From the stem plot the 8th term is 58

Thus the median is

$m = \frac{ 57 + 58}{2}$

=> $m = 57.5$

The stem plots for National League is

$2\ \ \ 9\\3\ \ \ \ 1\\4 \ \ \ \ 2\ 6\ 7\ 8\ 8\\5 \ \ \ \ 3\ 5\ 5\ 5\\6 \ \ \ \ 3\ 3\ 7\\7\\$

Generally the mean is mathematically evaluated as

$\= x = \frac{\sum x_i}{n}$

$\= x = \frac{29 + 31 + 42 + 46 + 47 + 48 + 48 + 53 + 55+ 55+ 55+ 63+ 63+ 67}{14}$

$\= x = 50.14$
