Find m∠MON<br> I have a hard time with theses

fredd [130]

Answer:

m∠MON = 15°

Step-by-step explanation:

The given parameters are;

m∠LON = 77°

m∠LOM = 9·x + 44°

m∠MON = 6·x + 3°

By angle addition postulate, we have;

m∠LON = m∠LOM + m∠MON

Therefore, by substituting the known values, we have;

∴ 77° = 9·x + 44° + 6·x + 3°

77° = 9·x + 44° + 6·x + 3° = 15·x + 47°

77° = 15·x + 47°

77° - 47° = 15·x

15·x = 77° - 47° = 30°

15·x = 30°

x = 30°/15 = 2°

x = 2°

Given that m∠MON = 6·x + 3° and x = 2°, we have;

m∠MON = 6 × 2° + 3° = 12° + 3° = 15°

m∠MON = 15°.

During the early part of the 1994 baseball season, many sports fans and baseball players noticed that the number of home runs be

Ratling [72]

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

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

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

$\= x = 50.14$
