A test tube contains 25 bacteria, 5 of which are can stay alive for atleast 30 days, 10 of which will die in their second day. 1
boyakko [2]

Answer:

c. \frac{1}{5}

Step-by-step explanation:

Given,

Number of bacterias who alive for at least 30 days = 5,

Bacterias who alive for 2 days = 10,

Died bacterias = 10,

Total bacterias = 5 + 10 + 10 = 25,

Ways of choosing a bacteria = ^{25}C_1 = \frac{25!}{1! 24!} = 25,

While, ways of choosing of a bacteria who will live after 1 week = ^5C_1 = \frac{5!}{1!4!} = 5,

Hence, the probability it will still be alive after one week = \frac{5}{25} = \frac{1}{5}

OPTION C is correct.

One of the formulas for calculating the correct dosage for a child is as follows: C= a/(a+12) ∙ 180
Brilliant_brown [7]
<u>I'm assuming you're formula is "</u><span><u>C=a/(a+12)*A" as that is only logical</u></span><span>

You get the formula </span><u>"C=a/(a+12)*A"

</u>You insert the numbers given, in place of the letters given.
<u>
</u>C=6/(6+12)*180
<u />C=3*180
C=540 mg

Which is of course wrong because it is more than the adults dosage. What i'm trying to say is "Your formula is incorrect , follow the steps I gave, but use the correct formula"
