Answer:
Step-by-step explanation:
a) Probability-Above 30 min = 5.72% = .0572
b) Probability-Above 15 min = 99.11% = .9911
c) *Probability-Between 1 - 59.49% = .4051
d) 19.136 minutes z = -1.28
Step-by-step explanation:
Monomial = x^2, 1 term
Binomial = x^2 + x, 2 terms
Trinomial = x^2 + x + 3, three terms
Binomial is more than 3 terms
Let's do a 3rd degree polynomial like:

- Now let's put parenthesis around (x^3 + 2x^2) and (4x + 8)
- Let's treat both of these as seperate for now. In the first part, you can see an x^2 can be factored out of it

- As you can see, if you do the distributive property, it equals the original.
Now let's factor the second part, the 4x + 8. This can be factored by a 4.

Your new equation is:

x^2 + 4 can be factored again down to (x + 2)(x + 2)
YOUR FINAL EQUATION IS:

Y=-a
x=b
a^2x-b^2y/ab=a+b
ax-by=2ab
Answer:
21
69
Step-by-step explanation:
Answer:
2.3+r=7.1
move all terms to the left:
2.3+r-(7.1)=0
add all the numbers together, and all the variables
r-4.8=0
move all terms containing r to the left, all other terms to the right
r=4.8 is the answer
