What you would have to do is distribute your three to each number in the parentheses using multiplication so your answer would be 6y+15
Place the decimal point right after the first nonzero digit, which is 3.
So you'll go from this
to this
after this move.
Now ask yourself: "how many spots must I move the decimal point to get back to 0.003045?"
The answer is "3 spots to the left"
The exponent of the final answer is -3
The negative indicates "move left" and the 3 tells us how many places to move the decimal
Therefore,
Answer: Choice C)This is assuming you meant to write the -3 as an exponent
Answer:
40.5
Step-by-step explanation:
(n-2)*180
(7-2)*180=5*180=900
10p+135+149+121+90=900
10p=-495+900=405
p=40.5

Answer:
B
Step-by-step explanation:
The Central Limit Theorem (something to look up!) says as the sample size increases, the sample mean approaches the population mean.
