Answer:
$52.44
Step-by-step explanation:
Long method:
1. Convert the percentage into a decimal (15/100 = 0.15)
2. Multiply the decimal by the cost of the haircut (0.15 x $45.60 = $6.84)
3. Add this product by the cost of the haircut ($6.84 + $45.60 = $52.44)
Quicker Way (easier w/ a calculator)
1. Add 100% to the percentage she wants to add (100% + 15% = 115%) You can also express this as a number (115/100 = 1.15)
2. Multiply this new percentage by the cost of the haircut (1.15 x $45.60 = 52.44)
In a single equation, it would be
Answer:
Minimum value = 43, ,
,
, Maximum value = 69.
Distribution is negative skewed.
Step-by-step explanation:
The given data set is
44, 43, 67, 68, 57, 65, 52, 62, 69, 54, 53, 61, 67, 48, 65
Arrange the data in ascending order
43, 44, 48, 52, 53, 54, 57, 61, 62, 65, 65, 67, 67, 68, 69
Divide the data in 4 equal parts.
(43, 44, 48), 52, (53, 54, 57), 61, (62, 65, 65), 67, (67, 68, 69)
Minimum value = 43
Maximum value = 69
Starting and end point of box plot represent the minimum and maximum value respectively. Box starts from the first quartile to the third quartile. A vertical line goes through the box at the median.
The shape of the distribution.
Normally distributed: If
Positive skew: If
Negative skew: If
For the given data set
Since , therefore the given distribution is negative skewed.
