Answer:
C
Step-by-step explanation:
the legs of a 30-60-90 triangle are 1 and
, while the hypotenuse is 2.
the ratio of the legs is therefore 1 :
→ C
Let the number be x.
6x-20=94
6x=114
x=19
Answer:
x=3cm
Step-by-step explanation:
This is a basic proportion question.
2/18 = x/27
(2x+1)(x+1)
Now multiply 2x to both x and +1
2x^2+2x
Do the same with 1 multiply it to x and +1
2x^2+2x +x+1
Simplify
2x^2+3x+1
First I let's represent our data in the table and make a scatter plot ( i attached the image).

Points labeled
A are called data set.
Point labelled
B is called the outlier. The outlier is a point that does not fit well with the rest of our data set. Posible
reason for point B is that someone is super smart and they don't need to spend a lot of time studying to achieve good results.
PartBWe can see from the graph that the number of hours spent on social media and test scores are negatively correlated. See a scatter plot, I added the trend line.
In other words, the more hours you spend on social media the lower your test scores should be.
