Answer: The price for the meal after the coupon was used is : 28.80

Explanation:

A percentage is basically a fraction, with a denominator of 100, so:

10% = 10/100

15% = 15/100

Hence, 20% is 20/100

This fraction can be reduced to 1/5

Next multiply 36 by 1/5:

36 x 1/5 = 7.2

Another way to get the answer would be dividing by the reciprocal

36 divided by the reciprocal of 1/5 is 5/1, or just 5.

5 divided by 36 is 7.2

So, just add a zero to the end: 7. 20, that number is the amount that will be taken off.

Now we do the number that is taken off minus the amount of the meal:

7.20 - 36 = 28.80

The price for the meal after the coupon was used is : 28.80

Hope this helps! :)

The mark up on an item is $3.75. If the mark up is 35%, what was the original price? Round

Answer:

$10.71

Step-by-step explanation:

$\frac{3.75}{y} =\frac{35}{100}$

y × 35 = 3.75 × 100

35y = 375

35y ÷ 35 = 375 ÷ 35

$y=10\frac{5}{7}$

y = 10.7142857143

10.7142857143 round to 10.71

The computer that controls a bank's automatic teller machine crashes a mean of 0.6 times per day. What is the probability that,

professor190 [17]

Answer:

0.2103 = 21.03% probability that, in any seven-day week, the computer will crash less than 3 times.

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:

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

In which

x is the number of sucesses

e = 2.71828 is the Euler number

$\mu$ is the mean in the given interval.

Mean of 0.6 times a day

7 day week, so $\mu = 7*0.6 = 4.2$

What is the probability that, in any seven-day week, the computer will crash less than 3 times? Round your answer to four decimal places.

$P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)$

In which

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

$P(X = 0) = \frac{e^{-4.2}*(4.2)^{0}}{(0)!} = 0.0150$

$P(X = 1) = \frac{e^{-4.2}*(4.2)^{1}}{(1)!} = 0.0630$

$P(X = 2) = \frac{e^{-4.2}*(4.2)^{2}}{(2)!} = 0.1323$

$P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = 0.0150 + 0.0630 + 0.1323 = 0.2103$

0.2103 = 21.03% probability that, in any seven-day week, the computer will crash less than 3 times.
