The answer is 'D'

When you divide 48 and 78 by 2, you get 24 and 39. Then divide 24 and 39 by 3 and you will get 8 and 13, which don't have any common factors.

The same happens with 12 and 30...
When 12 and 30 are divided by 2, you get 6 and 15. Then divide 6 and 15 by 3 and you get 2 and 5, which have no more common factors.

What percentage is 40kg of 1tonne?

shepuryov [24]

So using the conversion of 1 metric ton to kg, we see that there are 1000 kg in 1 ton. Then we can divide 40 by 1000 to find the decimal:

$\frac{40}{1000}=0.04$

Then to convert this decimal to a percentage, we must multiply by 100%:

$0.04*100=4$

So now we know that 40 kg is 4% of 1 ton.

Answer:

The 0 and 1 outcomes would be considered unusual.

Step-by-step explanation:

We can define as usual outcomes, the ones that fall between $\bar{x}\pm 3s$ .

According to a binomial distribution, s value is

$s=\sqrt{n*p*(1-p)}\\s=\sqrt{8*0.65*(1-0.65)}\\s=\sqrt{1.82}=1.35$

The expected value out of a 8 people sample is

$\bar{x}=p*n=0.65*8=5.2\\$

Then, our interval of usual values lies between

$\bar{x}- 3s\leq x \leq \bar{x} +3s\\\\5.20-3*1.35\leq x \leq 5.20+3*1.35\\1.15\leq x \leq 9.25$

We can conclude that 0 and 1 (the results that lie outside of the interval) are unusual.
