Answer:
-6x^2+21x+18
Step-by-step explanation:
It’s a straight line, and a straight line equals 180° so it would be:
180=6x+2x+12
180=8x+12
subtract 12 from both sides
168=8x
divide both sides by 8
21=x
the answer is 21 which is the second choice
Answer: p= 0.644
Step-by-step explanation:
We know that, the confidence interval for population proportion is given by :-
sample proportion(p) ± Margin of error(E)
Given confidence interval : (0.61,0.678)
i.e. p- E = 0.61 ... (i)
p+E = 0.678 ...(ii)
Adding (i) and (ii), we get
2p = 1.288
p= 0.644
From (ii),
E= 0.678-0.644
E= 34
Hence, the value of p = 0.644
Answer:
300
Step-by-step explanation:
100*45= 4500
15000-4500=10500
10500/35=300
