6 0

Step-by-step explanation:

Formula:  z = (x-μ)/σ

So, plug in the numbers.

N(14,4), find the z score for 9

x is the number you're finding, so x=9

μ is the mean, so μ = 14

σ is the st. deviation, so σ=4

Plug them in, so it's z=(9-14)/4 and you'll get your answer :)

hint: it should be a negative number

On a coordinate plane, a right triangle has points A (negative 5, negative 6), B (negative 5, negative 2), C (negative 2, negati
weqwewe [10]

The rise and run that would give us a similar right triangle on the same given line is: B. a rise of 8 and a run of 6.

<h3>What is the Rise and Run of Points on the Same Line?</h3>

The rise/run of any two points on the same line are have the same slope value.

Given the coordinates:

  • A(-5, -6)
  • B(-5, -2)

The rise of triangle ABC = change in y = 4 units

The run of triangle ABC = change in x = 3 units

Rise/run = 4/3

Therefore, a rise of 8 and a run of  6 would give us: 8/6 = 4/3.

This will give us a triangle similar to triangle ABC.

Therefore, the answer is: B. a rise of 8 and a run of 6.
