$34.99,, the middle numbers are $19.99 and $49.99, add them both and divide by 2 = $34.99
Answer:

The value of r is 0.451
The percentage decrease is about 45.1%
Step-by-step explanation:
The given exponential function is 
Using the exponent rule, 

Now the value of 
Thus, we can rewrite the function as

Therefore, the function in form 

The value of r is 0.451
The percentage decrease is about 0.451 ×100 = 45.1%
So each digits can only be selected once.
Let's start counting desired outcome.
Hundred position need to be at least 8. There is only one possible digits. So we will go with 8 and then there are 7 remaining digits.
One position can only be 2,4,6. because we need number to be even. So that's 3 possible digits. We will take one. 6 digits remaining.
Ten position can be anything so that would be 6 possible digits.
So the number of desired outcomes is 3·6 = 18.
Now count all outcomes.
Hundred, ten, and one position can get any digits
So that's 8·7·6 = 336
So the probability would be 18 / 336 = 3 / 56 ≈ 0.0536
Hope this helps.
Answer:
{a universal set is a set which contains all objects, including itself}
Step-by-step explanation:
a) you will create two circle, crossing over each other, and shade both the "A" the "B" and the middle space.
b) (AUB) means the same thing as universal set, but its called union, infact if you draw this out in Venn Diagrams this will be the exact same as answer (a).
c) A n B : mean A 'intersection' with B, so here you will only shade the area where both circles meet.
d) i am not sure of this one, sorry
