Answer:

t = 11

Step-by-step explanation:

Before we can solve this word problem, we have to translate first this problem into numerical form. The sum of fifteen and six times a number t is eighty-one can be translated into

        15 + 6t = 81

Let's subtract 15 from both sides of the equation .

        15 + 6t - 15 = 81 - 15

                        6t = 66

Divide both sides of the equation by 6.

                   6t / 6 = 66 / 6

                         t = 11

Answer:

  • P(x < 84) = 0.3085 or approximately 31%

============

<em>Hello to you from Brainly team!</em>

<h3>Given</h3>

  • Mean grade μ = 86,
  • Standard deviation σ = 4,
  • Grade limit x = 84.

<h3>To find </h3>

  • Probability of that a randomly selected grade is less than 84 or P(x < 84).

<h3>Solution</h3>

Find z-score using relevant equation:

  • z = (x - μ)/σ

Substitute values and calculate:

  • z = (84 - 86)/4 = - 0.5

Using the z-score table find the corresponding P- value.

  • P(x < 84) = 0.30854 or approximately 31%
