PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

Mathematics
1 answer:
Alinara [238K]2 years ago
6 0

Answer:  a) 6

<u>Step-by-step explanation:</u>

The mean is 375 which has a z-score of 0.

The standard deviation is 24 so:

  • z-score of 1 is: 375 + 24 = 399
  • z-score of 2 is: 399 + 24 = 423
  • z-score of 3 is: 423 + 24 = 477

A z-score of 3 is 99.85% from the left <em>(or 1 - 99.85% from the right = 0.15%)</em>

Since we are looking for the "more than" a z-score of 3, it is 0.15% of the total.

Consider functions f and g below.
Pani-rosa [81]

Answer:

D

Step-by-step explanation:

f(x) - g(x) = -9x^2 - 7x + 12 - (3x^2 - 4x - 15)  Remove the brackets

f(x) - g(x) = -9x^2 - 7x  + 12 - 3x^2 + 4x + 15

f(x) - g(x) = -9x^2 - 3x^2 - 7x + 4x + 12 + 15

f(x) - g(x) = -12x^2- 3x + 27
