Step-by-step explanation:
since all angles add up to 180:
(8x-1)+(3x+4)+(3x+9)=180
add like terms:
14x+12=180
x=12
Hope that helps :)
Answer:
4
Step-by-step explanation:
to find the slope, you have to do rise/run.
you rise up from the first dot 4 times,
then you run once.
4/1
so the answer is 4
Using the probability concept, considering complementary probabilities, there is a 0.12 = 12% probability that the integer is of 20 or more.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
If two events are complementary, the <u>sum of their probabilities is of 1</u>. In this problem, we have that an integer being less than 20 is complementary to an integer being 20 or more.
We have that:
- There is a 0.88 probability that the number is less than 20.
- There is a x probability that the number is 20 or more.
These events are complementary, hence:
0.88 + x = 1
x = 1 - 0.88
x = 0.12
There is a 0.12 = 12% probability that the integer is of 20 or more.
