The total amount she spent is equal to the sum of the amount for food and hotel accommodation. Letting x be the percent tax that Tracy was charged for his food, the equation that best represent the given is,
280.74 / 3 = 49 + (0.10)(49) + 32 + (0.15)(32) + (x)(32)
The value of x from the equation is 0.09. Thus, Tracy is charged 9% tax on his food.
Answer:
After three years, the amount in said account will be Rs $ 119,015.57.
Step-by-step explanation:
Given that Ashwin deposited rupees 75000 in a bank where the interest is credited half yearly to find the amount he will receive after 3 years at 16% per annum, the following calculation has to be made:
X = 75000 x (1 + 0.16 / 2)^3x2
X = 75000 x 1.08^6
X = 119,015.57
Thus, after three years, the amount in said account will be Rs $ 119,015.57.
Answer:
-4
Step-by-step explanation:
3(2)^2 - 5(2) - 6 = 12 - 10 - 6 = -4
Answer:
64.65% probability of at least one injury commuting to work in the next 20 years
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given interval.
Each day:
Bikes to work with probability 0.4.
If he bikes to work, 0.1 injuries per year.
Walks to work with probability 0.6.
If he walks to work, 0.02 injuries per year.
20 years.
So
Either he suffers no injuries, or he suffer at least one injury. The sum of the probabilities of these events is decimal 1. So
We want . Then
In which
64.65% probability of at least one injury commuting to work in the next 20 years
