A: 46/4x
B: 2/4x +6/4
C: 5/4x +6/4
D: 2/4x +11
To determine about how many more boys have a shoes size of 6 or less, you need to understand that a box and whisker plot takes a data set and show it in quarters (25% of the data is represented in each section).
For the 2 years olds, if the box in the middle, that means that half of the boys have a shoe size at 6 or under. There were 80 boys chosen for this study, so half of that is 40.
For the 3 year olds, the closest point to 6 is 6.5, and it is located after the line on the left. This means that only 25% of the boys have shoe sizes of 6.5 or under. 25% of the 60 three-year olds they collected data on is 15.
The difference is 40-15= 25.
There are about 25 more two-year olds wearing a size 6 or under.
Answer:
The answer is B, 7.83 meters.
Step-by-step explanation:
The mean of the six trees refers to the average height of all six trees. To find the mean value of any set of values, simply follow this formula:
Mean =
So for this particular question, my working was:
Mean = (5m + 8m + 12m + 6m + 11m + 5m)/6 = 7.833333333333m (Round off to 3 significant figures to get 7.83m)
Answer:
w=−7
Step-by-step explanation:
34+21=−11(w+2)
55=−11(w+2)
-55/11 =w+2
−5=w+2
−5−2=w
−7=w
