The gestation period of humans (266 ​days) is___ percent longer than the gestation period of pigs(115 days).
bija089 [108]
If we take 115 to be the 100%, how much is 266 off of it then?

\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
115&100\\
266&p
\end{array}\implies \cfrac{115}{266}=\cfrac{100}{p}\implies p=\cfrac{266\cdot 100}{115}
\\\\\\
p\approx 231.3

so 266 is about 231% of 115, which is 131% more than 115.

A bag contains 4 red marbles, 8 blue marbles and 2 green marbles. If two marbles are drawn out of the bag, what is the probabili
mina [271]

Answer:

The probability, to the nearest 10th of a percent, that both marbles drawn will be red is 28.5%

Step-by-step explanation:

Number of red marbles = 4

Number of blue marbles = 8

Number of Green marbles = 2

Total number of marbles = 4+8+2 =14

We need to find the probability, to the nearest 10th of a percent, that both marbles drawn will be red?

The formula used will be: Probability=\frac{Number\:of\:favourable\:outcomes}{Number\:of\;possible\:outcomes}\\

In our case, Number of favourable outcomes = 4 (as red marbles are drawn)

Number of possible outcome = 14 (Total number of marbles)

The probability will be:

Probability=\frac{Number\:of\:favourable\:outcomes}{Number\:of\;possible\:outcomes}\\\\Probability=\frac{4}{14}\\ Probability=0.2857\\

Now, calculating nearest 10th of a percent

Probability = 0.2857*100\\Probability=28.5%

So, the probability, to the nearest 10th of a percent, that both marbles drawn will be red is 28.5%
