Step-by-step explanation:
15+24=39
39 divided by 2
=19.5
If there is an even number of numbers locate the two middle numbers so that there is an equal number of values to the left and to the right of these two numbers. Step 3: If there is an odd number of numbers, this middle number is the median. If there is an even number of numbers add the two middles and divide by 2.
Answer:
10.5
Step-by-step explanation:
Given the data:
Age. l frequency
1-5. l 3
6-10. l 3
11-15. l 3
16-20. I 3
Mean :
Σfx / Σf
Obtain the midpoint (x) = (upper + lower boundary) / 2
Hence, midpoint x :
Age. l frequency | x
1-5. l 3 | 3
6-10. l 3 | 8
11-15. l 3 | 13
16-20. I 3 | 18
Σfx = (3*3) + (3*8) + (3*13) + (3*18) = 126
Σf = (3 + 3 + 3 + 3) = 12
Mean = Σfx / Σf = 126 / 12 = 10.5
The match took 30 minutes.
A minute watch covers 360 degrees every 60 minutes. In 30 minutes the watch therefore covers 180 degrees.
Answer:
$48.75
Step-by-step explanation:
In a calculator, you would multiply $65 by 0.75 (since that takes 0.25 off of 1, which is the whole). This gives you the answer of $48.75.
