Answer: (a) spuriousness relationship
Step-by-step explanation:
Spurious occurs between two variables that are actually caused by a third variable. Examples is like a number of teachers in region and number of people learn from college.
Answer:
f(-1) = -3
Step-by-step explanation:
(Assuming {2} is ^2)
f(-1) = 3(-1)² + 4(-1) - 2
= 3(1) - 4 - 2 = -3
Answer:
z=0.05 this is the answer
Answer:
Step-by-step explanation:
Isosceles triangles are a type of triangles in which two of their sides have an identical length. It should be noted that the angles opposite the sides that are the same length are also the same. This means that these triangles not only have two equal sides, but also two equal angles.
You can solve this problem using different methods, I will use pythagorean theorem. First take a look at the picture I attached. As you can see:
And we can find a easily using pythagorean theorem:
Solving for a:
Therefore:
Answer:
Step-by-step explanation:
The equation of a straight line can be represented in the slope intercept form as
y = mx + c
Where
m = slope = (change in the value of y in the y axis) / (change in the value of x in the x axis)
The equation of the given line p is
y = x - 1
Comparing with the slope intercept form, slope = 1
If two lines are parallel, it means that they have the same slope. Therefore, the slope of line q passing through (- 2, 8) is 1
To determine the y intercept, we would substitute m = 1, x = - 2 and
y = 8 into y = mx + c. It becomes
8 = 1 × - 2 + c
8 = - 2 + c
c = 8 + 2 = 10
The equation becomes
y = x + 10
