Answer:
The best estimate of the correlation coefficient is 0.9 from the given data.
Step-by-step explanation:
From the scatter plot, the line of best fit will have a positive slope.
So, the correlation coefficient ,
is greater than 0.
so,
≠ - 0.9
Also, there is a deviation from absolute linearity.
So,
≠ 1
Again from the scatter plot it is closer to linearity than further.
Hence,
≠ 0.3 .
So
= 0.9
Step-by-step explanation:
we know,

Therefore, nth term of a given gp is
16a
Answer:
B. f(x) = -x + 11
Step-by-step explanation:
First if you rearrange the equation you get f(x) = -x + 11, like this:
x + y = 11
Minus x from both sides
y = -x + 11
F(x) and y are interchangeable so we just put f(x) in
f(x) = -x + 11
Each of the graphs are attached and we see that they are the same!

Perimeter of the triangle, a+b+c
In this case, a=b=c=28
So, perimeter would be 28*3 = 84 cm
