Answer:a
a
b
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
10*50,10*30,10*40 are all the multples
6=3/2(4) + b solve to find b hope this helped
Answer:
-The equation r+b-33 represents the total number of marbles
-There 9 black marbles
-There are 24 red marbles
Step-by-step explanation:
The bag contains 33 red and black marbles. Let the number of black marbles be b and that of red marble to r
Total number of marbles will be
b+r = 33 i.e b+r-33 = 0... (1)
If the number of red marbles is 6 more than double the number of black marbles, this can be represented as;
r = 6+ 2b... (2)
Substituting 2 in eqn 1 we have;
b + 6+2b = 33
3b = 27
b = 9
r = 33-9
r = 24
This shows that there are 9 black marbles, 24 red marbles and the equation r+b-33 represents the total number of marbles in the bag.
