The reasons that the sample is representative:
The builders were chosen at random
The population included only builders who build in Vicki's town
Vickie wanted to determine the cost of building a house in her home, so the fact that the builders were from her town makes the sample more representative. Moreover, the random choosing of the builders helps to remove any biases that may be present.
Answer:
3 and 5
Step-by-step explanation:
In the expression on the right, the 8 is being multiplied by both 3 and 5. So the blanks should be occupied by 3 and 5.
Volume is length x width x height.
Calculate the volume of each rectangle and add them together.
7.5 x 7.5 x 3.55 = 199.6875
7.5 x 3.55 x 3.55 = 94.51875
Volume = 94.51875 + 199.6875 = 294.21 cubic meters
I think it is C)
I’m really sorry if I’m wrong.
