Answer:
B is correct
You can double check it! :)
Hope this helps!
Tips:
Select a condition, check the 4 tables and eliminate 2 tables at once.
Then check the remaining 2 tables.

Answer:
Let's define the variable x as the number of apples in each bag.
We know that she bought 4 bags, then the total number of apples that she has is:
Apples = 4*x
Now she eats one apple for each bag, then she eats 4 apples, so she now has:
Apples = 4*x - 4
And we know that this is equal to 28, then:
4*x - 4 = 28
now we can solve this for x.
4*x = 28 + 4 = 32
x = 32/4 = 8
x = 8
There are 8 apples in each bag.
For the diagram part, by a small online search y found the image that you can see below.
The diagram that correctly represents this situation is diagram C, where x represents the number of apples in each bag.
Answer:
See below
Step-by-step explanation:
The first two questions are slope = 0
a horizontal line has zero slope
slope = rise/run = 0 / run = 0
Greatest y value is + 4 from x = 3 to 4
the least y value is -3 fro x = -4 to -3
Answer:
Simple random sampling
Step-by-step explanation:
Simple random sampling is a subdivision of a sample chosen from a population. Individuals are randomly chosen by chance and each individual possess the same characteristics as every other person in the population. It is a a surveying technique that is unbiased.
The idea of this sampling method is that every object has an equal chance of being chosen.
If the researcher evaluates 200 students out of the population and make sure the sample reflects the population, the sampling method used is simple random sampling.
Slope of perpendicular lines multiply to -1
find slope of this line
slope=(y2-y1)/(x2-x1)
(x,y)
(5,7)
(3,1)
slope=(1-7)/(3-5)=-6/-2=6/2=3
perpendular lines have slopes taht mutliply to -1
3 times what=-1
-1/3
slope of perpendiular is -1/3
