X. 1. 2. 3. 4. 5. 6 are all the possible events when rolling a die. If it is a fair die then the probability of rolling any number is 1/6. So the probability of rolling at most a two is p(1)+ p(2)= 2/6 or 1/3
Answer:
x = 7, x = -3
Step-by-step explanation:
We can find the zeros by factoring the equation using the zero product property.
x^2-4x-21 = 0
(x-7)(x+3) = 0
<u>x-7 = 0</u>
x = 7
<u>x+3 = 0</u>
x = -3
Zeros are x=7 and x= -3.
Answer:
- Let the first number = x
- Therefore, the other number = x + 2 (x+2 is so as in two consecutive even numbers there is 1 odd number)
- Now, According to question
- x + x + 2 = 122
- 2x + 2 = 122
- 2x = 122-2
- 2x = 120
- x = 120/2
- x = 60
- Now, first no. = x = 60
- Therefore, second no. = x + 2 = 60 + 2 = 62
- Equation 60 + 62 = 122
