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.

Given the Venn Diagram what is the probability that a person is an only child OR only has sisters?
Svetradugi [14.3K]

Based on the venn diagram of siblings, the probability of being an only child or having only sisters is d. 0.50.

<h3>What is probability of being an only child or having a sister?</h3>

The probability of being an only child or having a sister can be found as:

= (Number of those only sister + Number of only children) / Total number of people in poll

Solving gives:

= (8 + 7) / (8 + 10 + 5 + 7)

= 15 / 30

= 0.50

In conclusion, the probability of having a brother and sister is 0.50.

The midpoint of JK is point L at (–1, 8). One endpoint is J(4, –15). Which equations can be solved to determine the coordinates
ycow [4]
Given two endpoints: (x_1,\ y_1) and (x_2,\ y_2), the midpoint of the two endpoints (x_m,\ y_m) is given by
(x_m,\ y_m)=\left( \frac{x_1+x_2}{2} ,\  \frac{y_1+y_2}{2}\right)

Thus, given the midpoint L(-1, 8) and one endpoint J(4, -15). The second endpont is given by
(-1,\ 8)=\left( \frac{x_1+4}{2} ,\ \frac{y_1+(-15)}{2}\right)
i.e.
\frac{x_1+4}{2} =-1 \\  \\ x_1+4=-2 \\  \\ x_1=-2-4=-6
and
\frac{y_1+(-15)}{2}=8 \\  \\ y_1-15=16 \\  \\ y_1=16+15=31
