Answer: A.Kelvin’s because he surveyed people leaving an area where food is sold


Step-by-step explanation:

Given: Kelvin and Lewie each design surveys in order to determine the number of people who buy food at the mall.

Kelvin surveys every other person leaving the food area.

Thus, he doesn't know about the people who do not buy food at mall whereas Lewie surveys every fifth person leaving the mall’s main entrance.

Thus, by this systematic random sampling he knows out of how many people the number of people buy food at mall.

Hence, Kelvin’s survey is likely to produce less valid results because he surveyed people leaving an area where food is sold.

Rút gọn (x-4) (x-3) -x(x+5) +82
WINSTONCH [101]

Answer:

-12x + 94

Step-by-step explanation:

Simplify:

\left(x-4\right)\left(x-3\right)-x\left(x+5\right)+82

=x^2-7x+12-x\left(x+5\right)+82

=x^2-7x+12-x^2-5x+82

=x^2-x^2-7x-5x+12+82

=-7x-5x+12+82

=-7x-5x+94

=-12x+94

Answer:

The total volume of the whole figure is 576m³.

Step-by-step explanation:

First find the volume for the first figure.

Volume of a Rectangular Prism (formula): L•W•H

V = (15m)(12m)(2m)

V = 360m³

Now, find the volume for the second figure.

V = (6m)(12m)(3m)

V = 216m³

Finally, just add both volumes to find the total volume of the entire figure.

Vt = 216m³ + 360m³

Vt = 576m³
