Answer:

  • a = ± 2

Step-by-step explanation:

Let the scale factor is k.

<u>Then the transformation is:</u>

  • (x, y) → (kx, ky)

<u>We have:</u>

  • (x, y) → (12x, 3a²y)

<u>The scale factor is k = 12, find the value of a:</u>

  • 3a² = 12
  • a² = 4
  • a = √4
  • a = ± 2

And in order to test this hypothesis we can use a one sample t or z test in order to verify if the true mean is at least 200 or no

Anika [276]

Answer:

0.1 for each case

Step-by-step explanation:

Because Jordan's teacher randomly calls on students and Jordan has 10% chance of being called on any given day, the probability that on the first day Jordan is called on is 0.1 Besides, the probability remains constant on any given day, so, the probability  that on the 2nd day Jordan is called on is 0.1 and for the 5th day is the same 0.1 Probability is always a number between 0 and 1.
