Answer:
7. Positive association
8. No association
Step-by-step explanation:
7. In this scatterplot, the points form a rough line that goes higher as the x values increase. In other words, it's tilting up, and its slope is positive. This signifies a positive association or correlation.
8. In this scatterplot, there seems to be no particular pattern; the points are random. Notice how there is no rough line or shape formed by these points. Since there is no relationship between "Salary" and "Height," there is no association or correlation.
Form a right angle triangle joining both given points to the origin, we get:
Perpendicular = 2 ( distance is always positive)
Base = 4 ( same logic)
Applying Pythagorus theorem
Hypotenuse = root of ( perpendicular squared + base squared)
Hypotenuse = root of 20 = 2 * root 5
Using x instead of theta
Sin x = perpendicular/hypotenuse
Cos x = base/hypotenuse
Sin x = -1/ root 5
Cos x = -2/ root 5
High probability of this answer being wrong.
Double check recommended.
Step-by-step explanation:
53 ÷ (-12 x - 4)
53 ÷ 48
= 1.10416
The answer is 4700 megabytes.
1 giga = 1000 mega
1 gigabyte = 1000 megabyte
4.7 gigabyte = x megabyte
1 gb : 1000 mb = 4.7 gb : x
x = 1000 mb * 4.7 gb : 1 gb
x = 4700 mb
We first need to find f(3).
f(3) = 2(3) + 8
f(3) = 6 + 8
f(3) = 14
We now want g(f(3)).
We know that f(3) is 14.
We also know that g(x) is 5.
As you know, 5 is a constant. No matter what the value of x is for g(x), it will not change the value of g(x).
So, g(f(3)) = g(14) = 5.
Answer: g(f(3)) = 5.
