first is proportional. y is 1 and 1/4 times x
second is not proportional.
reason? divided any y value by its corresponding x value and you'll keep getting 1.25, or 1 and 1/4. and the second one is not proportional because dividing the y values by their corresponding x value will give different answers.
maybe im wrong maybe im right you choose to trust me or not.
80, 84, 79, 44, 87, 73, 89, 90, 82, 89, 93, 97, 77, and 71 whats the mean

Answer:
sum up the numbers and divide by the numbers of values.
80+84+79+44+87+73+89+90+82+89+93+97+77+71 / 14
1135/14
= 81•1 is the mean
+ √6 = √9
The first step is to get by itself. We can do this by subtracting 
from each side, and simplifying 
= 3 -
Now we square both sides
5x = (3 - )²
Using the formula (a - b)² = a² -2ab + b², (3 - )² = 15 - 6
5x = 15 - 6
x = 
We know that
applying the Pythagoras theorem
LM²=LV²+VM²
LM is the radius of the circle
LV=5 in
VM=12/2----> 6 in
so
LM²=5²+6²-----> LM²=61------> LM=7.81 in------> LM=7.8 in
the answer is
7.8 in
