Answer:
<h2>A. 3</h2>
Step-by-step explanation:
Formula for locating the Median of a grouped data = (N+1)/2 th where
N is the total number of defects.
Total defects = 10+18+13+15+9+12
Total defects = 77
Median value = (77+1)/2 th value
Median value = 78/2 = 39th value.
We will cummulate the frequency (number of defects up to the 38th value) and locate the corresponding observation value.
On cummulating:
10+18+13 = 41
<em>We can see that the value of 38 falls on the third column(13), hence the median will be the equivalent number of observations i.e 3.</em>
Therefore the sample median is 3
Answer:
13
Step-by-step explanation:
Use the pythagorean theorem where 12 squared plus 5 squared is the square of the hypotenuse. 12 squared is 144 and 5 squared is 25. 144+25=169. Taking the square root of 169 we get 13. Therefore the missing side is 13 units long.
Hope this helps! (Please mark Brainliest)
I personally think it's C, but it could also be E, so.. idk for sure, sorry
Hope this helps tho!

Answer:
58.077 cubic cm
Step-by-step explanation:
Given that:
- height : 4.8 cm
- radius: 3.4 cm
As we know that, the volume of a conical perfume bottle is as following:
V = (1/3) * π * r² * h
So perfume can the bottle hold is:
V = (1/3) * 3.14 * 3.4² * 4.8 = 58.077 cubic cm
Hope it will find you well
