Factors of -36 that add to 13

Answers

Answer 1

Answer: To solve this problem follow the steps below.

Step 1:List out all of the factors for -36

-36: 1,2,3,4,6,9,12,18,36
-1,-2,-3,-4,-6,-9,-12,-18,-36

Step 2: Start going through a process of guessing and checking (basically take any two factors and add them together to see if they equal 13)

1 plus 12=13
9 plus 4=13

Step 3:Check your calculations and make sure you didn't make any errors

13-12=1 and 13-1=12
13-9=4 and 13-4=9

Answer: 1 and 12
4 and 9

I hope this helps and if any false information was given I apologize in advance.

A die is loaded so that the number 6 comes up three times as often as any other number. what is the probability of rolling a 1 or a 6?

Answers

The probability of rolling a value of 1 or 6 for the unfair die ls 1/2

The probability of an event is given as :

P(event) = Required outcome / Total possible outcomes

Let the probability of other numbers on the die = n

Therefore, Probability of 6 = 3n

The Cummulative probability can be expressed thus since the Cummulative sun must be equal to 1 :

Other values on the die are 5 ; 1, 2, 3, 4, and 5

5n + 3n = 1

8n = 1

n = 1/8

The probability of other numbers = 1/8

Probability of 6 = 3(1/8) = 3/8

Probability of (1 or 6) = P(1) + P(6) = 1/8 + 3/8 = 4/8 = 1/2

Therefore, the probability of obtaining 1 or 6 is 0.5

Answer:

1/2.

Step-by-step explanation:

Probability totals must add up to 1.

P = probability.

If P(any number other than 6) = x, then P(6) = 3x, so

3x + 5x = 1

x = 1/8

P(6) = 3/8 and P(not 6) = 1/8

Therefore P(6 or 1) = 3/8 + 1/8 = 1/2 (answer).
