Answers

The answer is 25.

The sequence was following the pattern of squaring numbers that were in chronological order.

1^2=1
2^2=4
3^2=9

3. Find a solution to the following system of equations.
-3x + 3y = -9
-3x + y = 7

Answers

Answer:

x = 5

y = 2

Step-by-step explanation:

-3x + 3y = -9

3y = 3x - 9

Equation 1. y = x - 3

-3x + y = 7

Equation 2. y = 3x + 7

So, put number 1 equation to number 2's y :

x - 3 = 3x + 7

x -3x = 7 + 3

-2x = 10

2x = 10

x = 10/2

x = 5

And, put x, which is 5 , to the any equation to figure out the y.

This time, I'll use equation number 1.

y = 5 - 3

y = 2

Jana has a number cube numbered 1 to 6. She plans to roll the cube 78 times. Predict the number of times Jana will roll a 2.

Answers

The number of times Jana will roll a 2 will be 13.

What is Probability?

Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.

The value of probability will be always in the range from 0 to 1.

Given that,

Jana has a number cube numbered 1 to 6.

When Jana rolls the number cube 1 time, there is an equal chance of getting each number.

Probability that the number is 2 = 1/6

So, there is a 1/6 probability that the number rolled is 2.

Jana plans to roll the cube 78 times.

So the number of times Jana will roll a 2 = 78 × (1/ 6) = 13

Hence the number of times that Jana will roll a 2 in the number cube is predicted as 13.
