Answer:
<em>We'll need to pull out 11 pairs of socks to be sure to get five pairs of white socks.</em>
Step-by-step explanation:
Combinations
We have 6 pairs of white socks and 6 pairs of black socks. If we wanted to pull out five pairs of white socks, there are to extreme scenarios:
The most favorable event is to take the five pairs in the first five takes. But that won't be for sure.
The worst case would be to take all the black socks first, and then take the five white socks. It would be a sure event and we must assume it as a possibility. Thus:
We'll need to pull out 11 pairs of socks to be sure to get five pairs of white socks
K=slope
b=y intercept
find slope
slope=(y2-y1)/(x2-x1)
(x,y)
(1,-2)
(-2,-8)
x1=1
y1=-2
x2=-2
y2=-8
slope=(-8-(-2))/(-2-1)=(-6)/(-3)=2/1=2
k=2
subsitute
y=2x+b
subsitute one point
(1,-2)
x=1,y=-2
-2=2(1)+b
-2=2+b
subtract 2
-4=b
y=2x-4
Answer:
Right triangle
Step-by-step explanation:
If the triangle has one angle that measures 50 degrees and another angle that measures 40 degrees, then the last angle must measure 90 degrees because the 3 angles of any triangle add up to 180, so we can set up the following:
180 - (50 + 40) = 90 degrees.
Any triangle that has a 90 degree angle is automatically a right triangle.
Hope this helps!
