- It is slightly difficult to write an effective questionnaire, that would able to test a vast knowledge/ conduct a survey so that an effective analysis can be done
Step-by-step explanation:
<span>y=x(x+5)(x-8)
The zeros of </span><span>y=x(x+5)(x-8), means to solve the value of x, when y =0
</span><span>y=x(x+5)(x-8) = 0
</span><span>
x(x+5)(x-8) = 0
x = 0 or (x+5) = 0 or (x - 8) = 0
x = 0 x + 5 = 0 x - 8 = 0
x = 0 -5 x = 0 + 8
x = -5 x = 8
Hence the zeros are x = 0, x = -5, x = 8</span>

Answer:
Step-by-step explanation:
You would add probabilities if you want to find out if one event or another could happen. For example, if you roll a die, and you wanted to know the probability of rolling a 1 or a 6, then you would add the probabilities:
Probability of rolling a 1: 1/6
Probability of rolling a 6: 1/6
So the probability of rolling a 1 or a 6 is 1/6 + 1/6 = 2/6 = 1/3.
