Answer:

B. 39

Step-by-step explanation:

The total market share values of the stocks does not influence on the price-weighted index, as the index is simply obtained by the sum of all share prices divided by the number of different stocks. The price-weighted index of the three stocks  is:

I=\frac{\$12+\$75+\$30}{3}\\I=\$39

The answer is alternative B. 39.

Six male and six female dancers perform the virginia reel. This dance requiresthat they form a line consisting of six male/femal
irga5000 [103]

Solution -

We have 6 males and 6 females. And in each group we have to choose one male and a female

For the first group we have (6,6) options, after choosing one pair we have (5,5) options, then (4,4) options, then (3,3) options, then (2,2) options, then (1,1) options.

So the first has 36 possibilities, 6 possible males, 6 possible females. 6 times 6 is 36.  

After picking up one male and female, we have 5 males and 5 females, 25 possibilities and so on.

Total we have 36×25×16×4×1 = 57600.

A large aquarium contains only two kinds of fish, guppies and swordtails. If 3/4​​ of the number of guppies is equal to 2/3​​ of
Jlenok [28]

Answer:

\frac{8}{17} of fish in this aquarium are guppies.

Step-by-step explanation:

Let x be the number of guppies and y be the number of swordtails in the aquarium,

According to the question,

\frac{3}{4}\text{ of } x=\frac{2}{3}\text{ of }y

\frac{3x}{4}=\frac{2y}{3}

By cross multiplication,

9x=8y

\implies \frac{x}{y}=\frac{8}{9}

Thus, the ratio of guppies and swordtail fishes is 8 : 9

Let guppies = 8x, swordtail = 9x

Where, x is any number,

Since, the aquarium contains only two kinds of fish, guppies and swordtails,

So, the total fishes = 8x + 9x = 17x

Hence, the fraction of fish in the aquarium are guppies = \frac{\text{Guppies}}{\text{Total fishes}}

=\frac{8x}{17x}

=\frac{8}{17}
