Basically you have to use trigonometry to solve this. You will be using a sine ratio. Type sin-1(36/43). Use the 2nd button to do this. Your answer should be 56.84659158 but round to 57.
" the quotient " means divide
The quotient of a number and 3 increased by 1....
(n/3) + 1 <==
The mean of the data is: 67.1
The median is: 70.5
The mode is: 71
<h3>What is the Mean, Median, and Mode of a Data Set?</h3>
- The mean = average
- Mode = data point that appears the most
- Median = center of the data.
Given, 68, 79, 71, 52, 71, 54, 71, 81, 54, 70:
Mean = (68 + 79 + 71 + 52 + 71 + 54 + 71 + 81 + 54 + 70)/10
Mean = 671/10
Mean = 67.1
Median = (70 + 71)/2 = 70.5
Mode = 71

Answer:
$2.45
Step-by-step explanation:
The sodas cost 3.35 so we're going to multiply that by 2 = 6.70
She only bought one hat so we're going to add 5.45 to 6.70= 12.15
She bought 2 hot dogs, so 2.70 times 2 = 5.40
Just add 12.15 to 5.40 and you get 17.55
Now subtract her 20 by 17.55 and the answer is 2.45
She will get 2.45 dollars back.
