Answer:
The second week had 10 more golfers than the first week.
Step-by-step explanation:
The graph clearly shows that the second week golfer are more than the first week. The median for week 2 is greater than the median of week 1. The graph of week 2 shows that number of golfers had increased and their age is between 60 to 80 years of age. The median of week 2 is 79 where as median of week 1 is 75.
Answer:
x^2 - 2xy + y^2.
Step-by-step explanation:
(x - y)^2
= (x - y)(x - y)
= x(x -y) - y(x - y)
= x^2 - xy - xy + y^2
= x^2 - 2xy + y^2.
Answer:
See answer above.
Step-by-step explanation:
These are the ordered pairs on the graph: (-2, 5), (2, 3), (-3, -2), (0, -5), (3, -6)
The domain is the first point in teach ordered pair and the range is the second number in the ordered pair.
So the domain is {-2, 2 , -3, 0, 3}
Range is {5, 3, -2, -5, -6}
F(n) = f(n â’ 1) â‹… 0.7 + 25, n > 0
Well, let's create a recursive function and see what option best matches it. Since our initial inventory is 100, we'll define f(0) as 100.
For month n, we sell 30% of the t-shirts. So we have f(n-1)*(1-0.3) = f(n-1)*0.7
And we get 25 more shirts. So f(n-1)*0.7 + 25
Therefore the function is
f(n) = f(n-1)*0.7 + 25, n>0
Which matches the 3rd option given.
The key thing to remember is if we sell 30% each month, that means that we retain 100% - 30% = 70% each month.
