the graph below shows the heights and arm spans of students in a class.

what association is there between height and arm span?
a positive correlation
no correlation
a very weak correlation
a negative correlation

a positive correlation

Step-by-step explanation:

We know that on a coordinate plane, a positive correlation exists when one variable increases as the other variable increases.

From the given graph, there is a positive correlation between the heights and arm spans of students in a class. because as the heights  increases the arm spans of students also increases.

Therefore, there is a positive correlation  between height and arm .

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
