Answer:
Step-by-step explanation:
height of water = ¾×12 = 9 inches
volume of water = 30×10.5×9 = 2,835 in³
<span>y = –5x + 6
y = –3x – 4
---------------subtract
0= -2x + 10
2x = 10
x =5
</span>y = –5x + 6
y = -5(5) +6
y = -25 + 6
y = -19
answer is <span>A. (5, –19)</span>
15,15,15,19,19,22,23,24,27,30,31,35,41,44,45
the mean (average) can be found by adding up all the numbers and dividing that by how many numbers there are.
The mean of this data set is : 405/15 = 27
the mode is the number that appears most often in ur data set
so the mode is : 15
the range is the highest number - the lowest number
the range is (45 - 15) = 30
the median is ur middle number
the median is : 24
ascending order (smallest to largest) is : mode, median, mean, range
