Answer: 24 cm
Step-by-step explanation:
Mrs Lopez cut 46cm of yarn.
Miss Hamilton then cut 22cm less than what Mrs Lopez had cut.
Mrs. Hamilton must have therefore cut:
This is a case of subtraction:
= 46 - 22
= 24 cm
The mean is simply the average of the data set.
Mean = (3+4+6+7+9+9+11)/7 = 7
The median, on the other hand, is the middle data when you arrange them from least to greatest. The middle data here is 7.
Hence, initially, the mean and median are equal. In order to make the mean less than median, add another data point which makes it the lowest. For example, we can add 1 as the new data point. The mean would be:
Mean = (1+3+4+6+7+9+9+11)/8 = 6.25
The median is (6+7)/2 = 6.5
Therefore, you can add any number less than 3. For example, that could be 1.
Answer:
The number of men = 108
Step-by-step explanation:
Total person = 396
ratio of women to men = 2:3
ratio of men to children = 1:2=2:4=3:6
Women = 2
Men = 3
Children = 6
Hence,
women+men+children = 2+3+6 = 11
Now finding out the percentage of each
Women = 2/11 * 396
= 792/11
=72
Men = 3/11 * 396
=1188/11
=108
Children = 6/11 *396
=2376/11
=216
Thus the number of men = 108 ....
