there are six female goldfish for every 10 male goldfish in the aquarium at the office there are 216 female goldfish in the aqua

aalyn [17]

Answer:

60 males in the aquarium

Step-by-step explanation:

It is a ratio problem. The ratio of female goldfish to male goldrish is 6:10. If you divide 216 (females) by 6 (females), you get 36. If you multiply 10 times 6, you get 60. So, the ratio turns into 216: 60. So, there are 60 males in the aquarium.

Can someone help asap

Galina-37 [17]

Answer:

37.2m^3

Step-by-step explanation:

Given: The dimension of a cuboid

$l(length)=6.2m\\w(width)=2.4m\\h(height)=2.5m$

To Determine: The volume of the container

The volume of a cuboid is calculated by the formula below:

$V cuboid=lxwxh$

Substitute into the formula the given dimensions

$V container=6.2m x2.4mx2.5m\\V container=37.2m^{3}$

Hence, the volume of the container is 37.2m^3

Answer:

0.055 = 5.5% probability that exactly 5 employees were over 50.

Step-by-step explanation:

The employees are removed from the sample without replacement, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x successes is given by the following formula:

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}$

In which:

x is the number of successes.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this question:

7 + 18 = 25 employees, which means that $N = 25$

7 over 50, which means that $k = 7$

10 dismissed, which means that $n = 10$

What is the probability that exactly 5 employees were over 50?

This is P(X = 5). So

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}$

$P(X = 5) = h(5,25,10,7) = \frac{C_{7,5}*C_{18,5}}{C_{25,10}} = 0.055$

0.055 = 5.5% probability that exactly 5 employees were over 50.
