Answer:
The social studies teacher should draw a random sample from all the students in each grade.
Step-by-step explanation:
The teachers will not be doing the activity, so their opinion is irrelevant. All boys in each grade targets a some audience and leaves the girl's voices unheard. All the students in the social studies club only represent a small portion of students who take the class. A poll of all the students in each grade will give the teacher the results they desire.
(Also, the formatting of this question is absolutely <em>horrible.</em> I had to reread it several times to understand the question. If you want people to answer you, make it legible.)
Do as the apples goes up in 4s
3 7 11 the goes 3 +4 = 7, 7+4 = 11
and Sees goes up in 40's
30 70 110
and rate of change is

its 40/4 or 10/1 (that's the first one)
F(11) means to replace x in the equation with 11
12(11) + 5
12 x 11 = 132
Now you have 132 + 5 = 137
F(11) = 137
Hey there! I'm happy to help!
Let's plug in our x value.
-3(6)+9y=18
-18+9y=18
We add 18 to both sides.
9y=36
We divide both sides by 9.
y=4
Have a wonderful day! :D
