Step by step explanation
x + 6 = 18
(We need to put the letters on one side and the numbers on the other)
To take the 6 over to the right, we minus it from both ends:
x = 12
It’s probably C and B. Is it right?
Answer: x=2
Step-by-step explanation:
To find the value of x, we have . To isolate x, we want to multiply both sides by 2 to get x alone.
x=2
Answer:B
Step-by-step explanation:
It’s not C because it has a point at 7.50 15, and 22.50, and since it increases the same amount each time that would mean it’s proportional. There for your answer would be B because saying it’s not proportional is false
- Ana has the greater median
- Ana also has the greater mean.
Averagely, Ana practiced for a greater amount of time each day.
<h3>What is the Mean and Median of a Data Set?</h3>
- Mean = sum of data points / number of data points.
- Median = center/middle of the data distribution.
Mean for ana= (20 + 20 + 30 + 60 + 60 + 60 + 70 + 70 + 100 + 100 + 100 + 115 + 115 + 115)/14 = 69.6
Mean for tara= (20 + 20 + 30 + 30 + 45 + 45 + 45 + 70 + 70 + 70 + 75 + 90 + 90 + 120)/14 = 58.6
Median for ana= 70
Median for tara= (45 + 70)/2 = 57.5
Ana has the greater median and also has the greater mean.
Averagely, we can conclude that ana practiced for a greater amount of time each day.
