Answer:
D. 0.821
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The combinations formula is important to solve this question:
is the number of different combinations of x objects from a set of n elements, given by the following formula.

Desired outcomes
The order is not important. For example, Elisa, Laura and Roze is the same outcome as Roze, Elisa and Laura. This is why we use the combinations formula.
At least 3 girls.
3 girls
3 girls from a set of 5 and 2 boys from a set of 3. So

4 girls
4 girls from a set of 5 and 1 boy from a set of 3. So

5 girls
5 girls from a set of 5


Total outcomes
5 from a set of 8. So

Probability

So the correct answer is:
D. 0.821
Answer:
b) 2.45
Step-by-step explanation:
The Euclidean distance in 3-space is the root of the sum of the squares of the x-, y-, and z-differences between the points.
<h3>Application</h3>
For the given points ...

The distance between x and y is ...

Answer:
12.5 miles
Step-by-step explanation:
-3,1 is 5 away from 2,1 so 2.5 times 5 equals 12.5
F(x) = 1/4x -3 = 1/4*12-3
= 1/45
