Adena has a number cube whose sides are labeled 1 through 6. She rolls the number cube three times.

1 answer:

5 0

On the first roll, the probability of rolling a 2 is 1/6. On the second roll the probability of rolling a 3 is also 1/6, and the probability of rolling a 4 on the third roll is, you guessed it, 1/6. Therefore the required probability is given by:
1/6 x 1/6 x 1/6 = 1/216

In a random sample of 30 sixth graders, 9 had traveled outside of the United States. There are a total of 120 sixth graders in t

36 students have traveled outside of the United States, when there are total 120 sixth graders.

Explanation

The number of students traveled outside of the United States is 9 when there is total 30 sixth graders. So, the ratio of the student traveled to the total students will be $9: 30 = 3: 10$

Now there are total of 120 sixth graders in the school and lets assume the number of students traveled outside the United states is $x$ . That means the ratio...

$x: 120 = 3:10 \\ \\ \frac{x}{120}=\frac{3}{10} \\ \\ 10x=360\\ \\ x=\frac{360}{10} \\ \\ x= 36$

So, 36 students have traveled outside of the United States.

Solve and show steps -2x+y=-7 and -2x-4y=-12

WITCHER [35]

Answer:

(x, y) = (4, 1)

Step-by-step explanation:

The coefficients of x are the same, so we can cancel the x-terms by subtracting one equation from the other. We want to do this so the resulting y-coefficient will be positive. That means we want to subtract the second equation from the first:

(-2x +y) -(-2x -4y) = (-7) -(-12)

5y = 5 . . . . . . . . simplify

y = 1 . . . . . . . . divide by 5

-2x +1 = -7 . . . . . substitute for y in the first equation

-2x = -8 . . . . . subtract 1

x = 4 . . . . . . divide by -2

The solution is (x, y) = (4, 1).
