The answer would be
1.265
Or
81/64
Answer:
21d(10d-3)
Step-by-step explanation:
21d x 10d = 210d^2
21d x 3 = -63d
so it would be 210d^2 - 63d
Mean: Add all of the numbers together, then divide by how many numbers there are. So, your mean is 40.6 (Rounded to the nearest tenth)
Median: The middle number (when they are in order). So, your median is 44.
Mode: The mode is whatever number appears the most; however, since there are no repeating numbers, there is no mode for this data set.
Range: Range is the difference between the highest and lowest values of the data set. So, your range is 55.
Let me know if you need any further explanation! :)

The linear equation that represents the relationship between earnings and tips will be y = 0.75x + 50.
<h3>What is a linear equation?</h3>
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Working as a waitress is Amanda. She receives $50 every day in addition to 75% of the tips her clients leave.
Let 'x' be the tip amount and 'y' be the total earning.
y = 0.75x + 50
Check:
At (20,65), then we have
65 = 0.75(20)+50
65 = 15+50
65=65
At (50,87.5), then we have
87.5 = 0.75(50)+50
87.5 = 37.5+50
87.5=87.5
At (100,125), then we have
125 = 0.75(100)+50
125 = 75+50
125=125
