Answer:
The profit of the bakery for this batch of rolls is C. $ 132
Step-by-step explanation:
You know the following this about the problem:
- xy=300 is the total cost of the production of the rolls, where x is the cost of the rolls and y is the number of rolls.
- Day 1 the bakery sold 4/5 of the rolls at 1.50 its value.
- Day 2 the bakery sold 1/5 of the rolls ar 0.8 of the price of Day 1.
The total gain of the sales is:
Day 1 + Day 2
and you know that xy =300, then the total gain is:
And the profit is the total gain less the total cost:
Profit = 432-300=132
First, compute the mean:
Next compute the absolute deviations for each datapoint:
|75-95.555|=20.555
|89-95.555|=6.555
|145-95.555|=49.445
|85-95.555|=10.555
|80-95.555|=15.555
|92-95.555|=3.555
|104-95.555|=8.445
|90-95.555|=5.555
|100-95.555|=4.445
Next we'll take the mean of these deviations:
The mean absolute deviation of your data is 13.8517
This type of combination problem involves combined probability, or the chance that a specific set could be chosen based on the probability of multiple variables.
The number that could be generated follows the example:
XXYZZZZ
where X describes a letter, and Y describes a number that isn’t zero, and Z describes any number.
Two probabilities exist in this situation, depending on the circumstances of the question. By pressing any number once, only 8 letters can be used (ten digits, minus the one and two keys, since they don’t have letters). This means that the probability of this event is:
8 x 8 x 9 x 10 x 10 x 10 x 10
where the two eights are for the letters, the nine is for the digit that isn’t zero, and the tens are for any numbers from the keypad. This permutation yields 5,760,000 choices.
If you are allowed to press the numbers more than once to generate a letter, then the probability changes to account for the entire alphabet. The new probability of this event is :
26 x 26 x 9 x 10 x 10 x 10 x 10
where this permutation yields 60,840,000 choices.
Hope this helps!
