Note that if you simply reflected it and dilated it, it would be too far to the left
note that the distances bewteen the axises in image 1 were 1 and 3in image 3,the distances are 2 and 6
seems to be 3 times
so it's the 90 counterclockwise rotation and dilation by scale factor of 3
answer is last one
Answer:
Step-by-step explanation:
- The mean of the number of hours worked by these students is 14 hours.
- The median is 12.5 hours.
The mean is the sum of all the hours listed divided by the number of seniors asked:
= ( 0 + 0 + 0 + 8 + 8 + 10 + 12 + 13 + 15 + 15 + 17 + 20 + 22 + 56) / 14
= 196 / 14
= 14 hours
The mean number of hours is 14 hours.
The median
Because the number of student interviewed is an even number, the median is calculated by taking the average of the two numbers in the middle.
<em>The numbers are ⇒ 12, 13</em>
Median is therefore :
= ( 12 + 13) /2
= 12.5 hours
In conclusion, the mean is 14 hours and the median is 12.5 hours.
