Answer:
4th row will result in the greatest mean.
Step-by-step explanation:
We are asked to find the row with greatest mean from our given rows.
We will use formula 
, where,
,
,
Let us find mean of each row using above formula.
Therefore, mean of 1st row is 2.8.
Therefore, mean of 2nd row is 3.
Therefore, mean of 3rd row is 3.2.
Therefore, mean of 4th row is 4.2.
Since 4th row has the highest mean, therefore, 4th row will result in the greatest mean.
The answer is A endurance
Answer:
see below
Step-by-step explanation:
342 m/s * 1.09361329834 yd /m * 1 mile / 1760 yards = .21251 mi/s
1500 mi / hr * 1609.344 meters / mile * 1 km / 1000 m = 2414 km/hr
Answer:
11 yards
Step-by-step explanation:
The room has two sides both measuring 10 feet 5 inches. This gives a total of 20 feet 10 inches. It also has the other two sides both measuring 6 feet 1 inch and that too gives a total of 12 feet 2 inches. Adding them all together results in 32 feet 12 inches. Better still, the perimeter of the room is derived as;
Perimeter = 2 (L + W)
Perimeter = 2 (10'5" + 6'1")
Perimeter = 2(16'6")
Perimeter = 32'12"
Having in mind our conversion rate of 12 inches equals 1 foot, the results can be properly expressed as 32 feet plus 1 foot which gives us 33 feet.
If the perimeter of Wendy's room is now given as 33 feet, the conversion rate between feet and yards can now be applied. Having been given that
3 feet = 1 yard
Then 1 yard = 3 feet/3, that is
y = 3/3
Hence,
y = 33/3
y = 11
The results show that Wendy would needs to buy a total of 11 yards of wallpaper border.
