Answer:
A Yana's average number of points is 0.5 points greater than Amber's
Step-by-step explanation:
i added up all of Yana's points = 15
I added up all of Amber's points = 12
then i divided them both by 6 because there is 6 numbers total so then i got
Yana = 2.5 Amber = 2
2.5 - 2 = 0.5 so Yana's average number of points is 0.5 points greater than Amber's

Answer:
142.5 in^2
Step-by-step explanation:
First, find the area of the rectangle
19*10= 190
Now find the area of the triangle
A=1/2bh
A=1/2(19)(10-5)
A=47.5
Since we need the shaded region, subtract the triangle area from the rectangle area
190-47.5=142.5
Suppose we have had S visitors in n months since EIS (Entry Into Service) of the site, then :
<span>S(n) = 8100 + 8100 * 3 + 8100 * 3^2 + 8100 * 3^3 + ... +8100 * 3^n </span>
<span>S(n) = 8100 * [ 1 + 3 + 3^2 + 3^3 + ... + 3^n ] </span>
<span>and we know that : </span>
<span>1 + 3 + 3^2 + 3^3 + ... + 3^n = (3^(n+1) - 1)/(3 - 1) </span>
<span>= (3^(n+1) - 1)/2 </span>
<span>therefore </span>
<span>S(n) = 8100 * (3^(n+1) - 1)/2 </span>
<span>finally : </span>
<span>S(n) = 4050 * (3^(n+1) - 1) </span>
<span>and this allows you to obtain the month n, if you know S(n) : </span>
<span>3^(n+1) = S(n) /4050 + 1 </span>
<span>therefore : </span>
<span>n = ln[S(n) /4050 + 1] /ln3 - 1 </span>
<span>hope it' ll help !!</span>
