The correlation is positive, negative and no correlation.
Ok, so 7 5 4
we know that the longest side must be less than the sum of the 2 othe sides
7 is longest
7<5+4
7<9
true
yes it can be (but it's not a right triangle)
Answer:
1600
Step-by-step explanation:
1600 is the answer because
321×5 = 1605 so estimation = 1605
Z

Z=kX
When x=6, z=18,
Finding value of z,
18=k*6
k=3
Z=3X
when x=10,
Z=3*10
Z=30
Part B;
Z

z=

Where x is a constant of proportionality,
when x=3, z=2
2=

a=3*2
a=6
When x is 13,
Z=
Given :
A function, f(x) = -6 + 12
To Find :
The value of f(x) when x= -3, x= 0 and x=1.
Solution :
Given function is f(x) = -6 + 12 .
Simplifying above function, we get :
f(x) = 6
Now, the given function is independent of x.
So, for any value of x the the value of functions remains constant.
Hence, this is the required solution.
