The correct answer is six.
Answer:
Step-by-step explanation:
Probability of good given properly adjusted P(G/P) = .5
Probability of bad given properly adjusted P(B/P) = .5
Probability of inappropriately adjusted P(I ) = .1
Probability of properly adjusted P(P) = .4
Probability of good given inappropriately adjusted P( G/I ) = .25
Probability of bad given inappropriately adjusted P(B/I ) = .75
P( G ) = P(G/P) x P(P) + P( G/I ) x P(I )
P(P/G) = P(G/P) x P(P) / P(G/P) x P(P) + P( G/I ) x P(I )
= .5 x .4 / .5 x .4 + .25 x .1
= .20 / .20 + .025
.20 / .225
20 / 22.5
= 4 / 4.5 .
= 8 / 9 .
Answer:
120?
Step-by-step explanation:
-5 times -2 equals 10 (since a negative times negative equals positive)
10 times -3 equals -30
-30 times -4 equals 120
Hope this helps.

Answer:
(f - g)(x) = -x + 8
General Formulas and Concepts:
- Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 2x + 1
g(x) = 3x - 7
(f - g)(x) = f(x) - g(x)
<u>Step 2: Simplify</u>
- Set up: (f - g)(x) = (2x + 1) - (3x - 7)
- Distribute -1: (f - g)(x) = 2x + 1 - 3x + 7
- Combine like terms: (f - g)(x) = -x + 8
Answer:
2.07 or 13.57
Step-by-step explanation:
First, you'd want to calculate the total bill. So you'd do the original bill multiplied by 1.18 (signaling the addition of the tip).
46 · 1.18 = 54.28
If you're calculating only the tip, it would be 46 · 0.18= 8.28
Then, since there is Martha, and 3 of her friends, you'd divide the bill (54.28) by 4 people. However, since the question is a little unclear on whether it is asking how much each person should leave for the tip, or leave overall, there are 2 possible answers.
Overall, each person would leave 54.28/4 = 13.57.
For the tip only, each person would leave 2.07.
