Answer:
10 x 10 x 10 divided by 9? =111.111111111
Answer:
Step-by-step explanation:
Y = 389.10 - 14.6 X.
Here when X increases Y decreases so correlation coefficient is negative .
correlation coefficient = - √ .657
= - .81
f(x)= -2x-3
Step-by-step explanation:
Step 1:
Let the sequence given here is -5, -7, -9, -11, -13 ......
Here the first term (a₁) of sequence is -5
And the common difference between the numbers in the sequence is
d= (-7-(-5)) = -7+5 = -2
Let the number of terms be x
Step 2;
To find the sequence function basic arithmetic sequence formula is
aₙ = a₁ + d( x-1)
Applying the values we get
f(X) = -5 + ((-2)(X-1))
on simplification
f(X) = -5 + (-2X+2)
f(X)= -5+2-2X
f(X)= -3-2X
