Given the data

X, ...rankX.....Y.....rankY......d=rx-ry........d²

4.........4...........-5......4................0..............0

53.......3.........-1........3................0...............0

86.......2.........13.......2................0................0

162......1..........16.......1.................0...............0

Then, using the rank correlation formula

p = 1 — 6•Σd² / n(n²—1)

p = 1 - 6• 0 / 4(4²-1)

p = 1 - 0

p = 1

So, the rank correlation is 1, this means that the two variables being compared are monotonically related, even if their relationship is not linear.

If I Had A Hammer Hardware has sales of $5000 in its first month. Suppose sales were to increase by 4% every month. In how many
mixer [17]

After 14 months after the first month would the sales reach $9000

For given question,

A Hammer Hardware has sales of $5000 in its first month.

The sales were to increase by 4% every month.

We need to find the number of months after the first month would the sales reach $9000

Let the exponential function for sales is,

f(n)= a (1 + r)^{n}

where, n is the number of months

a is the sales of the first month

r is the rate of increment

So, a = $5000, r = 0.04, f(n) = $9000

Substitute values in above equation.

⇒ 9000 = 5000 × (1 + 0.04)^{n}

Solve above equation for n.

⇒ 1.8 = (1.04)^n

⇒ n = log_{1.04}^{(1.8)}

⇒ n = 14.9

⇒ n ≈ 15

Therefore, after 14 months after the first month would the sales reach $9000
