I believe it is infinitely many.
Answer:
a) 118
b) 55
Step-by-step explanation:
a) Originally, there are 2 red balls and a total of 17 balls.
8/9 = (2 + x) / (17 + x)
8 (17 + x) = 9 (2 + x)
136 + 8x = 18 + 9x
x = 118
b) Originally, there are 8 white balls and a total of 17 balls.
1/9 = 8 / (17 + x)
17 + x = 72
x = 55
Answer: 0.1880
Step-by-step explanation:
The binomial distribution formula is given by :-
where P(x) is the probability of x successes out of n trials, p is the probability of success on a particular trial.
Given : The probability of new vehicles require warranty service within the first year : p =0.13.
Number of trials : n= 12
Now, the required probability will be :
Thus, the probability that none of these vehicles requires warranty service = 0.1880
Answer:
15. 3 cups left
16. C. 158 miles
Step-by-step explanation:
15. Each 1/2 cup makes 6. He made 24. 24 divided by 6 is 4. So he used 4 times 1/2 a cup, or 2 cups. 5 - 2 = 3.
16. Each dot is a day that had that many miles. You add all the miles together.
10 × 2 = 20
10 1/2 × 1 = 10 1/2
11 × 3 = 33
11 1/2 × 4 = 46
12 × 3 = 36
12 1/2 × 1 = 12 1/2
Total is 158
