Using the unit circle, the coordinates of the terminal point corresponding to 
is: (-0.5, 0.866).
<h3>What is the unit circle?</h3>
For an angle 
the unit circle is a circle with radius 1 containing the following set of points: 
.
In this problem, the angle is of , hence:
.
.
Hence the terminal point is:
(-0.5, 0.866).

Answer:
False
Step-by-step explanation:
We are given the following in the question:
Pearson correlation = 1.30
Pearson coefficient:
- The range of Pearson coefficient is from [-1,1]
- A positive correlation means that an increase in one quantity leads to an increase in another quantity
- A negative correlation means with increase in one quantity the other quantity decreases.
- +1 tells about a a perfect positive linear relationship and −1 indicates a perfect negative linear relationship.
Since, the given coefficient of Pearson does not lies in the range, it cannot express relation between two quantities.
Thus, a value of 1.30 does not indicates a strong correlation.
Thus, the given statement is false.
Answer: x=3/5
Step-by-step explanation:
The amount of chalk used by Maya which is the product of the fraction used and the total length of the chalk is 11/20 inches
Given the Parameters :
- Fraction of chalk used = 1/5
- Total length of chalk = 2 3/4 = 11/4 inches
<u>The total length of chalk used cannbe calculated thus</u> :
- Fraction used × total length of chalk
Therefore, <em>amount of chalk</em> used by Maya in inches is 11/20
