Answer:

4 kg of sugar would contain 1.2 \times 10^9 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

\frac{3}{9 \times 10^8} = \frac{4}{x}

Solve for x. Cross multiply.

3 \times x = 9 \times 10^8 \times 4

3x = 36 \times 10^8

3x = 3.6 \times 10^9

Divide both sides by 3

\frac{3x}{3} = \frac{3.6 \times 10^9}{3}

x = 1.2 \times 10^9

4 kg of sugar would contain 1.2 \times 10^9 crystals.

HELP PLEASE If L is the line through the point (-3,5) having a slope of 2/3 . Complete the equation of L
nalin [4]

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

Using the results from a survey of 1050 elibible voters, an approximate 98% confidence interval estimate for the proportion of v
Soloha48 [4]

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
