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

You have all five questions correct. Nice work

-------------------------------

Problem 1: There are 8 spaces labeled 1 though 8 so the proper sample space is {1,2,3,4,5,6,7,8} which is basically all the possible outcomes

Problem 2: There is one "3" out of 8 total, so 1/8 is the probability of landing on 3

Problem 3: There are 4 spaces that are even {2,4,6,8} out of 8 total {1,2,3,4,5,6,7,8}. So 4/8 = 1/2

Problem 4: There are 4 blue out of 3+5+4 = 12 total, so 4/12 = 1/3

Problem 5: We got 24 red out of 40 total, so 24/40 = 3/5

A security alarm requires a four-digit code. The code can use the digits 0–9 and the digits cannot be repeated.
never [62]

Answer:

The answer is <em>C</em>

Explanation: Given:A security alarm requires a four-digit code. The code can use the digits 0–9 and the digits cannot be repeated.  

there is only 2 numbers which are greater than 7 i.e. 8 and 9. ∴ there is 2 possibility for first place.

For the remaining 3 digits there is 9 possibilities (including 1 which would left after choosing 1 from first place )

No of ways for the alarm code beginning with a number greater than 7= 2 P 1 x 9 P 3

<em>Total ways of code with 4 digits= 10 P 4.</em> Hope this helps :)
