Answer:
0.59049
Step-by-step explanation:
Set of all digit strings of length 5
Digit range = (0 - 9) = 10
Length of digit = 5
Total possible outcomes = 10^5 = 100000
String without a 4 ;
Digit range = (0,1,2,3,5,6,7,8,9) = 9
Length of digit = 5
Required outcome = 9^5 = 59049
Required outcome / Total possible outcomes
59049 / 100000
= 0.59049
Answer:
The last one
.
Step-by-step explanation:
1) There are three trigonometric ratios for right-angled triangles.

In a right triangle, the hypotenuse, h, is the side opposite the right angle. Relative to the acute angle θ, check the attachment, the legs are called the opposite side, o, and the adjacent side a.
2) In this case, we are given a length and an angle to find x and y.
Let's find x first. To find x we need to use
.

Find y.
Notice that, we can use the Pythagorean Theorem
to find y.


3) Round them off to the nearest tenth.


Therefore, the correct choice is the last one
.
The average rate of change is the change in y divided by the change in x...
(f(8)-f(4))/(8-4)
(4-12)/4
-8/4
-2
So the average rate of change is -2.
