Answer: 15 ounces
Step-by-step explanation:
It is given that a company claims the average cereal in boxes of breakfast cereal = 15 ounces
And we know that the mean amount is nothing but the average amount of any data.
Mean is synonym word of average .
The statistical mean is the mean or average that is used to find the central tendency of the data in any question.
Thus, the expected mean amount of cereal per box = 15 ounces.
Given:
volume of the block = 576 cubic inches
Square pyramid = base area : 3 square inches ; height = 4 inches
Volume of square pyramid = a² * h/3
V = 3 square inches * 4inches/3
V = 4 cubic inches
volume of block / volume of square pyramid
576 cubic inches / 4 cubic inches = 144
She can make 144 square pyramids.
Let number of driveways , she shoveled on Sunday = x
And for 4 driveways , Kendra charges = 4*11=44
Therefore,
143 = 44 + 11x
And that's the model for the given situation .
Subtracting 44 from both sides,
143-44 = 11x
99 = 11x
Dividing both sides by 11
x = 9
Therefore she shoveled 9 driveways on Sunday .
