Answer:
Nine weeks
Step-by-step explanation:
So Bob is trying to go from 220 pounds to 175 pounds. That means he is trying to loose 220-175= 45 pounds. He is loosing 5 pounds per a week, so all we need to know is 45/5 which is equal to 9.
Answer:
solve for the parenthesis. PEMDAS
Take the value of g(x) and plug it into the x inside the radicand for F(x).
F(g(x)) = sqrt{8x - 13 + 9}
F(g(x)) = sqrt{8x - 4}
Done!

Answer: 0.48</h3>
==========================================================
Explanation:
Define the events
- D = person orders a drink
- H = person orders a hamburger
- F = person orders fries
The given probabilities are
- P(D) = 0.90
- P(H) = 0.60
- P(F) = 0.50
- P(F given H) = 0.80
The notation "P(F given H)" refers to conditional probability. If we know the person ordered a burger, then it changes the P(F) from 0.50 to 0.80; hence the events H and F are dependent.
----------------------
We want to find the value of P(H and F), which is the same as P(F and H)
We can use the conditional probability formula
P(F given H) = P(F and H)/P(H)
P(H)*P(F given H) = P(F and H)
P(F and H) = P(H)*P(F given H)
P(F and H) = 0.60*0.80
P(F and H) = 0.48
There's a 48% chance someone orders a burger and fries.
