The picture of the stem plot National and American League is shown on the first uploaded image
Answer:
The value is 
Step-by-step explanation:
From the question we are told that
The stem plot for National League is
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
=>

Answer:
y= -7
Step-by-step explanation:
y=ax+b
Find a where a=y2-y1 /x2-x1
y2=13,y1=5 x2=5,x1=3
substituting the values
a=13-5/5-2
a=8/2
a=4
substituting a into the formular
y=4x+b
taking x and y values let say 3 and 5 for x and y
the equation becomes
5=4(3)+b
5=12+b
5-12=b
-7=b
substituting the values of a and b into the equation
y=4x-7
when x=0
y=4(0)-7
y=0-7
y=-7
so when x=0,y=-7
W= width
l= length= 2w-3
Area= length * width
A= lw
substitute l=2w-3 for l
54= (2w-3)(w)
54= 2w^2 - 3w
subtract 54 from both sides
0= 2w^2 - 3w - 54
factor the polynomial
0= (2w + 9)(w - 6)
Set each set of parentheses equal
to 0 and solve for width.
0=2w+9
-9=2w
-4.5= w NEGATIVE VALUE
0=w-6
6 cm=w
-4.5 is not the answer because it has a negative value. You cannot have a negative side of a photograph. So substitute 6 in to find length.
length= 2w-3
l= 2(6)-3
l= 12-3
l= 9 cm
CHECK:
w= 6cm
l= 9cm
Area= length * width
54= 6*9
54= 54
ANSWER: width= 6cm; length= 9cm
Hope this helps! :)
Answer:
Well, the best way to think about it is base=bottom and then the height is the middle dotted line. The side lengths are the two sides of the triangle, not including the bottom. The two side lengths are 13 and the height is 12. I hope this helped a bit, if not then just let me know.
