Step-by-step explanation: Range is the distance between one point to the next. That would make A the correct answer.
Answer:
x =2
Step-by-step explanation:
y = - 2 x + 4
0 = - 2 x + 4
x = 2
It is rational because any number that can be represented in a fraction is rational. 4/33 is a fraction, so it is rational.
Answer:3
Step-by-step explanation:
Side by side on the left ,side by side on the right and two in the middle
We have 22 tickets sold, and 20 seats. This means that at least 2 passengers must not show up (otherwise, at least 21 passengers will be present, and there wouldn't be space for them).
Considering each passenger as independent, you can think of this experiment. Suppose you toss a coin for each passenger. If the coin lands on heads, the passenger shows up. If it lands on tails, the passenger doesn't show up.
But the coin is unfair: it has a 0.91 probability of landing on heads, and thus 0.09 probability of landing on tails.
This implies that the probability of having exactly
tails is

We already concluded that at least two passengers must not show up. So, if our coins lands on tails less than twice, we've lost. So, the losing probability is

Finally, remember the rule to negate events:

So, if we lose with probability 0.39, we win with probability
