I wanna say 10 or ether -10 since if it was subtracted from 2 then it would equal -8
Answer:
3. rolling a sum of 20 with two standard dice
Step-by-step explanation:
If something has a probability of 0 then there is no chance of it happening
A standard die goes up to 6. The max sum you can get by rolling two dice would be 12 as 6 + 6 = 12. So you have no chance of rolling a sum of 20 with two standard dice therefore the probability would be 0.
The answer is $37,923
<span>y = 844.697x^2 + 3723.485x - 13,650
x - number of years
y - the annual profit
If x = 8, the annual profit y is:
y = </span>844.697 * 8^2 + 3723.485 * 8 - 13,650
y = 844.697 * 64 + 29,787.88 - 13,650
y = 54,060.608 + 16,137.88
y = 37,922.728 ≈ 37,923
Answer:
B. 0.4
Step-by-step explanation:
Use the definition of the probability
![Pr=\dfrac{\text{Number of all favorable outcomes}}{\text{Number of all possible outcomes}}](https://tex.z-dn.net/?f=Pr%3D%5Cdfrac%7B%5Ctext%7BNumber%20of%20all%20favorable%20outcomes%7D%7D%7B%5Ctext%7BNumber%20of%20all%20possible%20outcomes%7D%7D)
You have to find the probability that a randomly selected reference book is hard cover. Hence, from the table
- Number of all possible outcomes = Number of Reference books = 25
- Number of all favorable outcomes = Number of Hardcover Reference books = 10
So, the probability is
![Pr=\dfrac{10}{25}=\dfrac{40}{100}=0.4](https://tex.z-dn.net/?f=Pr%3D%5Cdfrac%7B10%7D%7B25%7D%3D%5Cdfrac%7B40%7D%7B100%7D%3D0.4)
Any fraction in between the two
