If you don't want to compute Hannah's actual earning, you can just find a representative value for all the days. It can be the mean, median or mode. The easiest parameter that you can obtain without calculating is the media. Arrange the number of hours from least to greatest;
2.5 3.5 3.75 4.25 4.75
The median is 3.75. Assuming this is the number of hours for each day for 5 days, the estimated cost is:
Estimated Cost = 3.75*5*$5.85 = $109.7
Therefore, Hannah's estimate is more than the estimated cost.
Answer: 5808000 ways
Step-by-step explanation:
When it comes to selection, the combination formula is used to calculate the number of ways an item can be selected.
Using the combination formula of picking "r" items from a total of "n" items, the number of ways become:
nCr = n! /(n-r)! × r!
Hence,
to choose 3 different beverages from possible 12 = 12C3 = 220
to choose 3 different appetizers from possible 12 = 12C3 = 220
to choose 3 different deserts from possible 10 = 10C3 =120
Total number of ways to choose this meal = 220 × 220× 120 = 5808000 ways
Opposite of a negative is the same number as a positive
well, first off, let's notice that we have a trapezoid with a rectangle inside it, so the rectangle is really "using up" area that the trapezoid already has.
now, if we just get the area of the trapezoid, and then the area of the rectangle alone, and then subtract that area of the rectangle, the rectangle will in effect be making a hole inside the trapezoid's area, and what's leftover, is the shaded section, that part the hole is not touching.
