Answer:

Step-by-step explanation:

I think you set them equal to each other.so you would do 16x+2=15x+5 and you would get x=3. I hope this helps out! ☺️

A car was originally purchased in January 2010 for 27000 dollars. The car depreciates at a rate of 18% every year.

Maksim231197 [3]

Answer:

Number of year(n) = 3.4 year (Approx)

Step-by-step explanation:

Given:

Purchase value of car = $27,000

Depreciation rate per year (d) = 18% = 0.18

Future price = half of its original value = $27,000 / 2 = $13,500

Find:

Number of year(n) = ?

Computation:

$Future price =Purchase value(1-d)^n\\\\13,500=27,000(1-0.18)^n\\\\0.5=(0.82)^n\\\\n=3.444(Approx)$

Number of year(n) = 3.4 year (Approx)

Answer:

5, 6, 7

(5 + 6 + 7)/3 = 6

<u>Standard deviation:</u>

σ = $\sqrt{((5 - 6)^2+(6-6)^2+(7-6)^2)/3} = \sqrt{2/3}$

Correct choice is d

-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5

(-5 -4 - 3 - 2 - 1 + 0 + 1 + 2 + 3 + 4 + 5)/11 = 0

<u>Standard deviation:</u>

σ = $\sqrt{((-5)^2+(-4)^2+(-3)^2+(-2)^2+(-1)^2+0^2+1^2+2^2+3^2+4^2+5^2)/11} = \sqrt{10}$

Correct choice is d

3, 4, 5, 6, 7

<u>Standard deviation:</u>

σ = $\sqrt{((3-5)^2+(4-5)^2+(5-5)^2+(6-5)^2+(7-5)^2)/5} = \sqrt{2}$ ≈ 1.4

Correct choice is d
