Let's say the TV cost $100
Now if we multiply 0.08(.85(100)) we'll first get $85 which is 15 percent off.
If we choose option A then that will be wrong because you're new total would be $15 dollars instead of $85
Option B when multiplied by .08 will bring the price of the TV all the way down to $6.80 which that doesn't make sense.
Multiplying by 1.08 will be considered as tax and therefore option C is correct.
21 goes into 221 about 10 times
21x10=210
Answer:
240
Step-by-step explanation:
Note the following:
Every minute is equal to 60 seconds.
4 multiplied by 60 WPM (word per minute) is 240
17.54% is the probability that 5 messages are received in 1 hour.
The chance that X reflects the number of successes of a random variable in a Poisson distribution is provided by the following formula:
P(X = x) = (
×
) ÷ x!
In where x is the number of successes, e is the Euler number, and u is the mean in the specified time frame.
In this case, the average message rate is 5 messages per hour.
The probability of receiving 5 texts in one hour.
Determine the value of P for x = 5 and u = 6.
P(X = x) = (
×
) ÷ 5!
P(X = x) = 21.0560 ÷ 5!
P(X = x) = 0.1754
There is a 17.54% chance that 5 messages will be received in 1 hour.
