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.

Look for the graph where the line crosses the y axis at y=-1, and whose slope is -3. The answer is b.
Answer:
1399/200 699.5%
Step-by-step explanation:
We shall use the formula for distance traveled:
s = ut + (1/2)at^2
where
u = initial velocity
t = time
a = acceleration.
Because
u = 0 (car starts from rest),
t = 10 s (travel tme),
a = 2 m/s^2 (acceleration), m
the di mstance traveled is
s = (1/2)*(2 m/s^2)*(10 s)^2 = (1/2)*2*100 = 100
Answer: 100 m
Answer: B) Infinitely many solutions; both equations are equivalent
==============================================================
Work Shown:
x+y = 4 ... start with the first equation
x + (-x+4) = 4 ... replace y with (-x+4)
x-x+4 = 4
0x+4 = 4
0+4 = 4
4 = 4 ... this is a true statement regardless of what x you pick
So there are infinitely many solutions. Each solution (x,y) is of the form (x,-x+4). All solutions fall on the line y = -x+4 which is equivalent to x+y = 4. Note how we add x to both sides.
Or you could start with x+y = 4 and subtract x from both sides to get y = -x+4. Either way, we're dealing with the same equation which is why they both graph out the same line.
