Ipatiy [6.2K]3 years ago
5 0

Answer:

TRUE

Step-by-step explanation:

The “mean” of the sampling is always equal to the population mean. If repeated random samples of size n, where the proportion in the category is p, then the mean of all sample proportions is the population proportion. Therefore, the answer is TRUE.

A rectangular box with an open top has a length of x feet, a width of y feet, and a height of z feet. It costs $4.30 per square
almond37 [142]

Answer:

C=$(4.30xy+5.40(xz+yz))

Step-by-step explanation:

Surface Area of a Cuboid=2(LW+LH+HW)

Since the top is open

Surface Area = LW+2(LH+HW)

If Length = x feet,

Width =y feet

Height = z feet

Surface Area = xy+2(xz+yz)

Area of the base=xy

If it costs $4.30 per square foot to build the base

Cost of the base=Cost Per Square Foot X Area = $4.30xy

Area of the sides =2(xz+yz)

If it costs $2.70 per square foot to build the sides

Cost of the sides=Cost Per Square Foot X Area of the sides

= 2.70 X 2(xz+yz)

=5.40(xz+yz)

Cost of Constructing the Box = Cost of Constructing the Base + Cost of Constructing the Sides.

Therefore,

C=$(4.30xy+5.40(xz+yz))
