n a science lab, a number of rock samples are weighed. If the scientist finds one of the rocks to weigh 6 pounds and this is 47.5% of the total weight of all of the rocks, what is the weight of all of the rocks? If necessary, round your answer to the nearest tenth.

lol we need to see what the question is asking about

step-by-step explanation:

the probability that a bird is green (.30) is true

step-by-step explanation:

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.
