Answer:
4 kg of sugar would contain
crystals.
Step-by-step explanation:
Given that 3kg of sugar contains 9 × 10⁸ crystals, let "x" represent the number of sugar crystals 4kg of sugar would contain.
Thus, set up a proportion as follows:
3 kg : 9 × 10⁸ = 4 kg : x

Solve for x. Cross multiply.



Divide both sides by 3


4 kg of sugar would contain
crystals.
point slope form (y-y1) = m(x-x1)
y-5=(2/3)(x-(-3))
y-5=(2/3)(x+3) add 5 to each side and distribute
y= 2/3x +2/3 *3 +5
y = (2/3)x +2 +5
y = (2/3) + 7
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
