Answer:
5x+ y =1 is in standard form
A is true: the absolute value of 0.92 is close to 1, and 0.92 is positive.
B is false: correlation can also be negative.
C is false: the absolute value of -.17 is closer to 0 than 1; therefore, it is a weak correlation.
D is true: the absolute value of .01 is very close to 0, meaning that there is no significant correlation.
E is true: correlation can range from -1 (perfect negative) to 1 (perfect positive).
F is false: it measures the strength and direction between two numerical variables!
In conclusion, A, D, and E are true.
These are expression written as a function of sine, cosine and tangent. The value of x from the given function is 4.29
Trigonometry expression
These are expression written as a function of sine, cosine and tangent.
Given
tanx² - 1/3 = 0
Add 1/3 to both sides
tanx² - 1/3 + 1/3 = 0 + 1/3
tanx² = 1/3
x² = arctan(1/3)
x² = 18.44
x =4.29
Hence the value of x from the given function is 4.29
