It would be one fourth cause he tells you the fraction of how many guppies are red

I think it goes like this:
1/4 of 2/5= 2/20 or 1/10

It's asking what fraction are red guppies and it's telling us that 2/5 of the tank is made up of guppies and out of that 2/5, 1/4 of them are red. So you would have to figure out what 1/4 of 2/5 is to find out how many red guppies there are.

How to find the area under the standard normal curve between z 1.5 and z 2.5?
alisha [4.7K]
It is possible to calculate mathematically the area under the normal curve between any two values of z.
However, tables/software have been developed to give the areas under the normal curve to the left of particular values of z.  The function is the probability of Z<z, or P(Z<z).
The area between two values z1 and z2 (where z2>z1) is therefore 
P(Z<z2)-P(Z<z1).

For example, to find the area between  z1=1.5, z2=2.5
is 
P(Z<2.5)-P(Z<1.5)
=0.99379-0.93319
=0.06060

(above values obtained by software, such as R)
For example, the value P(Z<2.5) can be calculated using
P(Z<2.5)=erf(2.5/sqrt(2))/2+1/2
where erf(x) is a mathematical function that does not have an explicit formula (calculated by summation of series, or tabulated).

51,013.84 kilometers

Step-by-step explanation:

1 kilometer= .6214

So you have to divide 31,700 by .6214

You get 51,013.839 or round it to 51,013.84
