Answer: strong positive correlation
Explanation:
A positive correlation exists when the correlation coefficient that we've is greater than 0. This means that both variables that are given move in the same direction.
Since the correlation between the number of hours Brad studies and the grades he gets is 0.8, it means that there's a strong positive correlation due to the fact that the value is close to +1.
This means that the number of hours that Brad studied is a good predictor of
the grade that he gets in his examination but it's not perfect.
Depends on the context. If you told more then I could help.
Answer: 360°
Explanation;
Lines of longitude are imaginary lines that used along with latitudes allow us to be able to locate points on Earth. Longitudes are drawn vertically on maps with the most popular one being the Prime( Greenwich) meridian.
As the Earth is spherical, the lines of longitude encircle the Earth which means that an entire longitudinal line will be 360°. As maps are flattened out, the longitudinal line is divided into 2 such that the longitudinal lines seen on a map are 180° each. When a line of longitude is added to its opposite, they will reform the original line that runs around the earth thereby making 360°.
