He practiced for 1 hour and 30 minutes
So 12.44 hours=460.28 oz
divide
so
oz/hour means hour=1 so divide
460.28/12.44=37/1
the answer is 36 fluid ounces per hour
Answer:
98 ft²
Step-by-step explanation:
There are a couple of ways you can think about this one. Perhaps easiest is to treat it as a square with a triangle cut out of it. The cutout triangle has a base (across the top) of 14 ft and a height of 14 ft, so its area is ...
A = (1/2)(14 ft)(14 ft) = 98 ft²
Of course the area of the square from which it is cut is ...
A = (14 ft)² = 196 ft²
So, the net area of the two triangles shown is ...
A = (196 ft²) - (98 ft²) = 98 ft²
_____
Another way to work this problem is to attack it directly. Let the base of the left triangle be x. Then the base of the right triangle is 14-x, and their total area is ...
A = A1 + A2 = (1/2)(x ft)(14 ft) + (1/2)((14-x) ft)(14 ft)
We can factor out 7 ft to get ...
A = (7 ft)(x ft + (14 -x) ft)
A = (7 ft)(14 ft) = 98 ft²
Answer:
The height appear to be reported because there are disproportionately more 0s and 5s.
Step-by-step explanation:
Given the data :
0 0 0 0 0 0 0 0 0 1 2 3 3 3 4 5 5 5 5 5 5 5 5 5 5 5 6 8 8 8 9
Creating a frequency table :
Last digit ______ Frequency
0 ______________ 9
1 _______________ 1
2 _______________1
3 _______________3
4 _______________ 1
5 _______________11
6 _______________ 1
8 _______________ 3
9 ________________1
From the frequency distribution table, it could be seen that the volumeof 5's and 0's are far more than the volume of the other digits. We could infer from this numbers were reported and not measured.
