The group that is most likely to have a lower mean age of painting students is group A.
<h3>
Which group is most likely to have a
lower mean age?</h3>
A dot plot is graph that is used to display data. The dots in a dot plot represents the frequency of a number.
Looking at the graph, it appears that group A has a lower age distribution. Thus, it is likely that it would have a lower mean.

I am looking at ur first answer choice.....but something is off..
2^-4 = 1/(2^4) = 1/(2*2*2*2) = 1/16...this is correct
but ur answer choice says 2^-4 = 1/(2^-4)...and its supposed to equal 1/(2^4).
But I still think ur answer choice is A
X − 4y = 7
5x + 9y = 6
5x − 20y = 35 //1st * 5
5x + 9y = 6
5x +9y - 5x + 20y = 6 - 35 //2nd - 1st
5x + 9y = 6
29y=-29
5x=6-9y
y=-1 //1st : 29
5x=6-9*(-1)
y=-1
x=15:5 //2nd : 5
y=-1
x=3
check:
for x=3 and y=-1 there is:
x − 4y = 7 is 3 − 4*(-1) = 7 is 7=7 ok
5x + 9y = 6 is 15-9=6 is 6=6 ok
answer: (3;-1) represents the solution.
