In a standard deck of cards, there are 48 cards that are not sevens. Therefore the probability of not drawing a seven is 48/52 = 12/13 (92.31%).
Answer:
x is 64 degrees
Step-by-step explanation:
Since the polygon is a quad we know all the angles add up to 360. So, we can do :
100 + 130 + 66 = 360 - x
296 = 360 - x
Subtract 360 on both sides
-64 = -x
Multiply by negative one on both sides and we get
64 = x
x is 64 degrees
1/8 = 0.125
3/20 = 0.150
Therefore 1/8 < 3/20
Answer: 
Step-by-step explanation:
To find the inverse of a function start by replacing f(x) with x and replace the original x with y.

Now solve for y

Finally, replace y with the inverse of f(x), 
Yay, implicit differnentiation
when you take the derivitive of y, you multiply it by dy/dx
example
dy/dx y^2=2y dy/dx
for x, the dy/dx dissapears
ok
so differnetiate and solve for dy/dx
3y² dy/dx-(y+x dy/dx)=0
expand
3y² dy/dx-y-x dy/dx=0
3y² dy/dx-x dy/dx=y
dy/dx (3y²-x)=y
dy/dx=y/(3y²-x)
so at (7,2)
x=7 and y=2
dy/dx=2/(3(2)²-7)
dy/dx=2/(3(4)-7)
dy/dx=2/(12-7)
dy/dx=2/5
answer is 2/5
