Answer:
21
Step-by-step explanation:
The sum of degrees in a triangle is 180, so we have:
3x+100+x-4=180
add 4 on both sides
3x+100+x=184
subtract 100 on both sides
3x+x=84
Combine like terms
4x=84
84/4 = 21

The total number of books on the shelf is 12 books
Given the following parameters
Total number of puzzle books on the shelf = 30 books
If the number of puzzle books is 25 of all the books on the shelf, the total number of books on the shelf is expressed as:
= 2/5 of 30
= 2/5 * 30
= 2 * 6
= 12
Hence the total number of books on the shelf is 12 books

Answer: D. 0.860
Step-by-step explanation:
In the table we can see that he rolled the cube 1000 times, and he recorded that 140 of those times he rolled a 5.
Then, the probability of rolling a 5 will be equal to:
P1 = 140/1000 = 0.14
Now, the probabilty of NOT rolling a 5, is equal to the rest of the probabilities, this is:
P2 = 1 - 0.14 = 0.86
then the correct option is D
