Furkat [3]

We have a + b = 180 and a = 12 + b;
Then, 12 + b + b = 180;
12 + 2b = 180;
2b = 168;
b = 84;
a = 12 + 84;
a = 96;

faust18 [17]

<span>Subtracting 2x from both sides of the equation would be a reasonable first step in solving this equation as it properly combines like terms to the left side of the equation. It quickly shows that the next step would be adding 1 to both sides of the equation, which would have us arrive at the answer of x = 5.</span>

The picture of the stem plot National and American League is shown on the first uploaded image

Answer:

The value is $\= x = 50.14$

Step-by-step explanation:

From the question we are told that

The stem plot for National League is

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

The sample size is n = 14

Generally the stem plot is interpreted in this manner

The numbers on the first column represents the tens of a two digit number while the second column holds the possible unit number the tens in the first column can be combined with

for example 4th row

5 3 5 5 5

is equivalent to

53 55 55 55

Generally the mean for the national league is mathematically represented as

$\= x = \frac{29 + 31 + \cdots + 67}{14}$
