hjlf

Answer:

1 / 18

Step-by-step explanation:

In a roll of two dice :

Number of faces on a dice = 6

Total sample space for 2 6-sided dice = (number of faces)^Number of dice = 6^2 = 36

Total possible outcomes = 36

Required outcome = sum of 11

11 = {(5,6) ; (6, 5)}) = 2 possibilities

Probability = required outcome / Total possible outcomes

P(obtaining a sum of 11) = 2 / 36 = 1/18

1. Given f(x) =1/4 (x – 8), what is the value of f(24)?

goldenfox [79]

Hi there!

»»————-　★　————-««

I believe your answer is:

$f(24)=4$

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

$f(x)=\frac{1}{4}(x-8)\\-----------\\\rightarrow f(24)= \frac{1}{4}(24-8)\\\\\rightarrow f(24) = \frac{1}{4}( 16)\\\\\rightarrow\boxed{f(24)=4}$

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.
