the principal uses a computer to randomly select the name of a student from all the students in the school. with the computer program, it is possible to draw the of the same student twice. if the principal selects the name of a student from the voyagers on the first try, what is the probability she will draw the name of another student from the voyagers on the second try.

81/399

Step-by-step explanation:

Let the first Voyager drawn be

Let the second Voyager drawn be

The equation would be

The total, as seen on the chart, is 400. Subtract to get 399.

The number of Voyagers in total is 82. Subtract to get 81.

Substitute this values in the equation to get the fraction

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
