Answer:

BC = 22

Step-by-step explanation:

BD = 67

Bc = 3x - 2

CD = 4x + 13

BC + CD = BD (Given)

3x - 2 + 4x + 13 = 67

3x + 4x -2 + 13 = 67

7x + 11 = 67

7x = 67 - 11

7x = 56

x = 56 ÷ 7

x = 8

now instead of x put 8

Bc = 3x - 2

BC = 3(8) -2

BC = 24 -2

BC = 22

elena-s [515]

Answer:

Step-by-step explanation:

C=0.14×7,200=1008

Nadia made a total of $1008 last week in commission sales

b). To express the total amount she made in 2011, we derive the formula below;

Total amount (2011)=Average weekly commission× number of weeks in 2011

where;

Average weekly commission=$1008

number of weeks in 2011=52

replacing;

Total amount (2011)=(1008×52)=52,416

The total amount Nadia in commission in 2011=$52,416

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

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

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

$\= x = 50.14$
