Ok, to solve this first you have to set up your proportion:

9/150=x/230

/ is a fraction

x= the number of vials it will take to treat 230 patients

in order to solve this, you have to cross multiply:

9 x 230= 2070

150 · x= 150x

so you get 150x=2070

then divide 2070 by 150

2070/150= 13.8

so it would take 13.8 vials of medicine to treat 230 patients

<span>Okay, firstly, you want to work out how many people will 1 vial of malaria treat. So, you do this: 

150 divided by 9= </span><span>16.6

</span><span>That means for every 1 vial, 16.6 people are treated.
</span>
<span>Since the question asks you to find out how many vials are needed if you're required to treat 230 people, you would do this:
</span>
230 divided by 16.6= <span>13.8

</span>That means you need 13.8 vials to treat 230 people.

3liters of juice to the ratio 5:3:4
Radda [10]

Step-by-step explanation:

Let 3 litres of juice be divided into 5x, 3x and 4x parts.

\therefore \: 5x + 3x + 4x = 3 \: litres \\  \therefore \: 12x = 3000 \: ml\\ \therefore \: x =  \frac{3000}{12}  \\ \therefore \: x =  250 \: ml \\  \therefore \: \\  5x = 5 \times 250 = 1250 \: m = 1.25 \: l \\ 3x = 3\times 250 = 750 \: ml  = 0.75 \: l\\ 4x = 4 \times 250 = 1000 \: ml  = 1 \: l\\

According to the U.S. Census Bureau, the mean of the commute time to work for a resident of Boston, Massachusetts, is 27.3 minut
Bond [772]

Answer:

By the Chebyshev Theorem, at least 75% of commuters in Boston has a commute time within 2 standard deviations of the mean

Step-by-step explanation:

Chebyshev Theorem

The Chebyshev Theorem can also be applied to non-normal distribution. It states that:

At least 75% of the measures are within 2 standard deviations of the mean.

At least 89% of the measures are within 3 standard deviations of the mean.

An in general terms, the percentage of measures within k standard deviations of the mean is given by 100(1 - \frac{1}{k^{2}}).

What minimum percentage of commuters in Boston has a commute time within 2 standard deviations of the mean

By the Chebyshev Theorem, at least 75% of commuters in Boston has a commute time within 2 standard deviations of the mean
