What the Median?<br>
2,3,4,5,6,6,7,8,8,10,11,12,13,13,14,18,19,20,20
Reil [10]
Median is the number in the middle when you organize them in increasing or decreaseing order
they are already in increaseing order so
count how many numbers there are
19 numbers
the middle would be
add 1 and divide by 2
19+1=20
20/2=10
10th number
count
10 is median

The x intercept is a point where the graph of the function, intercepts the x-axis.
So the coordinate of that point is (x, 0) , that is, y must be 0 since the point is on the x-axis.
letting y=0, we find:
<span>10x-15y=30
</span><span>10x=30
x=3
With the same logic, letting x=0, we find the y-intercept:
</span><span>10x-15y=30
</span><span>-15y=30
y=-2
Answer:
x- intercept : 3 [point (3, 0)]
</span>y- intercept : -2 [point (0, -2)]
New York Boat
Distance = 3470 miles
rate = x + 5
time = 50 hours
London Boat
Distance = 3470 miles
rate = x
time = 50 hours
50(x + 5) + 50x = 3470
Take it from here.
Let's bear in mind that 5 gallons with a solution of 6% bleach, contains some water plus some bleach, how much bleach? well, is just 6% of 5 gallons or namely (6/100) * 5 gallons, or 0.30 gallons.
if we use "x" gallons of water, well pure water has no bleach, so is 0% bleach, and it has a (0/100) * x or 0x gallons of bleach.
the mixture will be say "y" gallons, and is 4% bleach, so (4/100) * y is 0.04y gallons in the mixture of bleach.
To be honest i need more data but i think its 173m and 17300cm
