Answer:

1) \boxed{729}

2) \boxed{169}

Step-by-step explanation:

1) 27²

<em>This means 27 is being multiplied 2 times.</em>

So,

=> 27*27

=> 729

2) 13²

<em>This means 13 is being multiplied 2 times</em>

So,

13*13

=> 169

➷ Substitute in the value:

840 - 52.5(14) = 105

Since e(14) = 105, the elevation of the cable car would be 105 meters from the ground 14 minutes after it begins descending  from the top of the hill

The valid probability distributions are the ones in options C and D.

<h3>Which of the following are valid probability distributions?</h3>

For discrete random variables with probabilities p₁, p₂, ..., pₙ, there are two rules:

  • All of these probabilities are numbers between 0 and 1.
  • p₁ + p₂ + ... + pₙ = 1.

So, for the first rule we can discard the first option, where we have negative probabilities.

To check the other 4 options, just add the probabilities and see if the addition gives 1.

The options that add up to 1 are C and D, so these two are the correct options.

D: 1/5 + 1/10 + 1/10 + 1/10 + 1/5 + 1/10 + 1/10 + 1/10 = 1

C: 1/6 + 1/6 + 1/6 + 1/6 + 1/6 + 1/6 = 1
