Given:
The location of 4 points on a coordinate plane.
To find:
The points whose y-coordinate is less than -1.5.
Solution:
From the given graph it is clear that, the coordinates of the given points are A(2,1), B(-4,-4), C(-1,1) and D(1.5,-2).
For the point A(2,1), the y-coordinate is 
.
For the point B(-4,-4), the y-coordinate is 
.
For the point C(-1,1), the y-coordinate is .
For the point D(1.5,-2), the y-coordinate is 
.
The y-coordinates of the points B and D are less than -1.5.
Therefore, the correct options are B and D.
Given:
The set is
To find:
The correct option for the given set which represents the quality that is not in the given set.
Solution:
We have,
It is the set of ordered pairs. So, it is a relation.
For each x-value there is a unique y-value value. So, it is a function.
All elements are real numbers but they not distinct and they are in ordered pairs. So, the given set is not a set of real numbers.
In one to one functions each image has exactly one preimage and each preimage has exactly one image.
In the given set 4 has two preimages 3 and 4. So, the given set is not a one to one function.
Therefore, the correct options are C and D.
Answer:
not rejecting the null hypothesis when it is false.
Step-by-step explanation:
Significance level or alpha level is the probability of rejecting the null hypothesis when null hypothesis is true. It is considered as a probability of making a wrong decision. It is a statistical test which determines probability of type I error. If the obtained probability is equal of less than critical probability value then reject the null hypothesis.
Answer:
3 inches of wood
Step-by-step explanation:
It is just a simple equation of 8-5.
Answer:
an average of around 16 calls per day
Step-by-step explanation:
Simply divide 500 by 30 and that comes out to 16.66666
But because you cannot take half a call you just use 16 as your answer!
