Your answer to the first one is incorrect.

We can cut the plan into two figures, a rectangle with side lengths of 4 cm and 5 cm and a rectangle with side lengths of 1 and 2 cm.

Perimeter of a Rectangle:

P = 2(l + w)

P = 2(4 + 5)

P = 2(9)

P = 18

Perimeter of a Rectangle:

P = 2(l + w)

P = 2(2 + 1)

P = 2(3)

P = 6

Add up the perimeters:

18 + 6 = 24

So the total perimeter is 24.

For the 2nd one, your answer is also incorrect.

We multiply 5 to the perimeter of the plans:

5 * 24 = 120

Not sure what the third one is asking.

For the fourth one we just multiply 'k' to the perimeter:

24 * k = 24k

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%
