Answer:
Step-by-step explanation:
By using linear regression calculator,
Linear regression equation representing the data set will be,
y = 7.79x + 34.27
Correlation coefficient of the line will be,
R = 0.98
Since, correlation coefficient of the line is (+0.98), relation between the two variables is a strong linear relationship.
That means hours spent studying has the strong relation with test scores obtained.
Answer:
x = 30° and 330°
Step-by-step explanation:
Assuming the intervals is {0 , 2π} or {0° , 360°}
So it means it lies in the 2nd and 4th quadrant because tangent is negative in the 2nd and 4th quadrant
so the two solutions are
x = 30° and 330° or
Hi! :)
So a right triangle is a triangle that contains a ninety degree angle, it's not classified by side length. A scalene triangle is a triangle in which all three sides are different lengths. An isosceles triangle has two sides that are the same length. Either a scalene or an isosceles triangle could contain a right angle, so your answer is yes.
Hope this helps!
Just multiply the base times height times width which would give you 800
