Option A: drop of 8 meters would be correct because a drop in this case indicates something has been removed. -8 equals 8 below 0.
Answer:
A) 2631.20
Step-by-step explanation:
8% of 32,890 is 2631.2
Answer:
Step-by-step explanation:
60 minutes = 1 hour
The statement would be
"Customers arrive at a checkout counter in a department store according to a Poisson distribution at an average of seven per 60 minutes
If it takes approximately ten minutes to serve each customer, then the mean service time for in minutes for customers arriving during a 1-hour period is
10/60 × 7 = 1.67
In Poisson distribution, variance = mean
Therefore,
Variance = 1.67
The probability that the total service time will exceed 2.5 hours is expressed as P(x > 2.5)
Converting 2.5 hours to minutes, it becomes 2.5 × 60 = 150 minutes
From the Poisson distribution calculator,
P(x > 150) = 0
Based on the given situation, if x is number of kilograms of lobster, you can write the following expressions:
51 + 5x cost in the first restaurant
33 + 8x cost in the second restaurant
In order to determine the value of x which makes the cost the same in both restaurants, equal the previous expressions and solve for x:
51 + 5x = 33 + 8x subtract 33 both sides and 5x subtract both sides
51 - 33 = 8x - 5x simplify
18 = 3x divide by 3 both sides
18/3 = x
6 = x
x = 6
Hence, the weight of the lobster is 6 kg.
The cost of the dinner is:
51 + 5(6) = 51 + 30 = 81
Hence, the cost of the dinner is $81
