Answer:
8x+8y
Step-by-step explanation:
y + 3x + 4y + 2x + 3y +3x
<em>With</em><em> </em><em>this</em><em> </em><em>we</em><em> </em><em>group</em><em> </em><em>x</em><em> </em><em>with</em><em> </em><em>x</em><em> </em><em>and</em><em> </em><em>y</em><em> </em><em>with</em><em> </em><em>y</em><em> </em><em>and </em><em>in</em><em> </em><em>ascending</em><em> </em><em>order</em><em> </em><em>so</em><em> </em><em>x</em><em> </em><em>comes</em><em> </em><em>before</em><em> </em><em>y</em>
3x+2x+3x
And the y with y
y+4y+3y
Which is;
3x+2x+3x+y+4y+3y
8x+8y
Answer:
The correct answer is the last on that’s states: it is not a valid sample because it is not a random sample of the population.
Step-by-step explanation:
When a researcher wants to know about the same thing, he/she has to take a sample from the population.
Example, consider a researcher wants to know how many hours the students study at home in a week, so the researcher has to take the sample from the student population.
Here, he/she gives the advertisement and offers $10 for 10 people. Therefore for anyone can come they might not required for a particular study.
Therefore, the answer is the last one.
Answer:
C) No, their slopes are not opposite reciprocals.
Step-by-step explanation:
First we find the slopes.
slope of PQ = (3 - 0)/(7 - 11) = 3/(-4) = -3/4
slope of RS = (-3 - 1)/(6 - 3) = -4/3
product of the slopes = (-3/4) * (-4/3) = 1
The slopes are reciprocals, but they are not opposite reciprocals, so the lines are not perpendicular.
Answer:
D) Fewer than one-quarter of the plants are taller than 7 inches and shorter than 10 inches.
Step-by-step explanation:
There are 17 total plants, 17/4=4.25
Plants taller than 7 inches and less than 10 are 8 or 9 inches tall
There are 3, 8 inch plants
There is 1, 9 inch plant
The total plants between 7 and 10 inches is 4
