Answer:

T(h) = 20 - 3h

Step-by-step explanation:

We are told that for every km you go up, the temp goes down 3°.

Let's say you go up 1km, then the temp should be 17°. We can easily represent it by the equation: T(h) = 20 - 3h

If we go up 1km: T(1) = 20 - 3*(1) = 20 - 3 = 17°

If we go up 2km: T(2) = 20 - 3*(2) = 20 - 6 = 14°

If we go up 3km: T(3) = 20 - 3*(3) = 20 - 9 = 11°

Find the probability for choosing a letter at random from the word: Probability P(not P) A.) 1/11 B.) 2/11 C.) 5/11 D.) 10/11​
elixir [45]

Answer:

D.) 10/11

Step-by-step explanation:

Here the given word Probability has 11 letters in it. And we have to calculate the Probability of not selecting a letter P from the above word.

So the formula for calculating any probability is Total Favorable outcomes / Total number of outcomes.

Here total number of outcomes are 11 as word Probability has 11 letters.

So the probability of selecting letter P from word Probability =  \frac{1}{11}

Now the P(not P) = 1 - P(selecting letter P)

                            = 1 - \frac{1}{11} = \frac{10}{11}
