The answer would be $8029.91
Answer: B.
Step-by-step explanation: (0, 2), (2, 0), and (1, -1) are the correct coordinates of the three vertices of the triangle.
Answer:
66 2/3 mL
Step-by-step explanation:
Let v represent the volume in mL of added 30% solution. Then the amount of salt in the mix is ...
0.10×100 +0.30×v = 0.18(100 +v)
0.12v = 0.08(100) . . . . .subtract (0.18v +0.10×100)
v = 8/0.12 . . . . . . . . . . . divide by the coefficient of v
v = 66 2/3 . . . . mL
Adding 66 2/3 mL of 30% salt solution to 100 mL of 10% salt solution will make 166 2/3 mL of 18% salt solution.
To find the median, order the numbers in the data set from least to greatest (or greatest to least, either one works) and then find the number in the middle. If there are 2 numbers in the middle, find their mean.
Step 1: Ordering the numbers.
<span>Original: 100, 88, 76, 78, 92, 94, 84, 98, 82, 90
Ordered: </span>76, 78, 82, 84, 88, 90, 92, 94, 98, 100
Step 2: Find the median (middle number).
The median is the number in the center.
Count in from each side equally to find the middle number.
76, 78, 82, 84, 88, 90, 92, 94, 98, <span>100
</span>78, 82, 84, 88, 90, 92, 94, 98
82, 84, 88, 90, 92, 94
84, 88, 90, 92
88, 90
88 and 90 are the middle numbers.
Since there are 2 numbers in the middle, we must find their mean.
Step 3: Find the mean of the 2 middle numbers.
Mean is also known as average.
To find this, add up the numbers and then divide by the amount of numbers there are.
In this case, that means adding 88 and 90 then dividing their sum by 2.
This can be represented by the equation (88 + 90) ÷ 2.
88 + 90 = 178
178 ÷ 2 = 89
89 is the final answer, it is the median.
Answer:
The median of this data set is 89.
Hope this helps!
