A special 8-sided die is marked with the numbers 1 to 8. It is rolled 20 times with these outcomes: 3 4 5 2 7 1 3 7 2 6 2 1 7 3
Greeley [361]
The prime numbers on the dice are 1,2,3,5 and 7 , the theoretical  probability is 
\frac{5}{8}, which is 62.5%, the number of prime numbers in the outcome is 15, so the experimental probability is \frac{3}{4}, which is 75%, the difference between the experimental probability and the <span>theoretical probability is 12.5%.</span>

I could use some help please! please

Answer:

The integers could be 21 and 22

or -22 and -21

Step-by-step explanation:

If two integers are consecutive, then it means that their difference is just 1

if we have the initial value as x , then the other value could be x-1 or x + 1

let us go with x-1

So the product here is;

x(x-1) = 462

x^2-x = 462

x^2 -x -462 = 0

x^2 -22x + 21x - 462 = 0

x(x-22) + 21(x-22) = 0

(x + 21)(x-22) = 0

x = -21 or x = 22

If x = -21

x -1 = -21-1 = -22

if x = 22

x -1 = 22-1 = 21
