Answer:
n = 0.8
Step-by-step explanation:
3n + 3 = 5.4
-3 form each side
3n=2.4
÷3 for each side
n=0.8
Answer:
Part A is ≤ means less than OR equal to. < only means less than
Part B is 9
Step-by-step explanation:
A: Because it would equal 19, and 19 is equal than 19. 4(5) - 1 would equal 19, which is equal to 19, and not less than. ≤ means less than or equal to. < means less than. So its not true.
B: 47 - 2, 45. Then 5 x 9 equals 45. So 5 x 9 equals 45, then add 2 would equal 47.
Answer:
a) 0.122
b) 3.35 × 10⁻⁴
c) 0.1071
Step-by-step explanation:
Here we have the Poisson process given by

Where:
λ = Rate = 4 bites/hour and
t = Length of time that is
Mean = λt
Where k = 6 fishes bites and t = 2 hours we have

b) The probability that he fails to catch any fishes during the first two hours is the probability t that he catches 0 fish as follows

(c) Here we have

For 1 fish caught in two times we have first time no fish and second time he caches a fish gives
0.122×(1-0.122) = 0.1071
Answer:
A) $28.14 B) $8.14
Step-by-step explanation:
1 * 12.95 = $12.95
2 * 3.20 = $6.40
1 * 8.79 = $8.79
we add up all these numbers, 28.14
well he has only 20 bucks, so he still needs 28.14-20= $8.14
