Answer:
0.61596
Step-by-step explanation:
Given that:
λ = 5 (5 errors per page)
Poisson distribution formula :
P(x = x) = (λ^x * e^-λ) / x!
Probability that page does not need to be retyped means that error on page is less than or equal to 5
P(x ≤ 5) = p(x = 5) + p(x = 4) +... + p(x = 0)
The individual probabilities can be obtained using the formula above or the use of a calculator
P(x ≤ 5) = 0.17547 + 0.17547 + 0.14037 + 0.08422 + 0.03369 + 0.00674
P(x ≤ 5) = 0.61596
Step-by-step explanation:
"Of" means multiplication, and percent means out of 100.
25/100 × 150 = 700/100 × n
75/2 = 7n
n = 75/14
n ≈ 5.357
I believe it is C. The quadratic function.
Answer:
challenge because it said 28 people spent between 15 and an hour if that is so the could have been there for an hour so there
Step-by-step explanation:
<span>$3375
Since each car requires 1 driver and there's 135 cars, that means that there's 135 drivers. And since each driver paid $25, just multiply the number of drivers by $25 to get the total amount of money the drivers paid in all.
135 * $25 = $3375.</span>
