So if there are 3 boys to every 4 girls, and there are 42 boys, the answer would be 42 to 56????? I'm not quite sure, and it's probably wrong, but that's how we learned in my school.
Answer:
He made a reasonable inference.
Step-by-step explanation:
Rodriguez asked 60 randomly chosen students about their favorite types of reading materials.
Of those 60 students, 12 chose science fiction.
In percent this is about 
%
Mr. Rodriguez drew an inference that about 20% of middle school students prefer to read science fiction.
We can see that this inference is correct. He made a reasonable inference as his sampling was non biased and completely random.
Answer:
x = 41
y = 24
Step-by-step explanation:
Systems of equations is,
-2x - 7y = -250 ------(1)
4x - y = 140 ------(2)
Equation (1) multiplied by 2 then added to equation (2)
-4x -14y = -500
(+) 4x - y = 140
-15y = -360
y =
y = 24
by putting y = 24 in equation (2),
4x - 24 = 140
4x = 140 + 24
x =
x = 41
For x = 41 and y = 24 both the equations are true.
Equation (1), -2(41) - 7(24) = -250 [True]
Equation (2), 4(41) - (24) = 140 [True]
Step-by-step explanation:
I am guessing that is 1011? Just to be safe, I will do 4706*10 and 4706*1011.
4706*10: So, 4,706 times 10 is 47060
4706*1011: 4,706 times 1011 is 4757766
Standard notation is the normal way of writing numbers. So the answers I wrote are all in Standard notation.
