Step-by-step explanation:
If two lines, segments, or rays intersect at right angles, then they are perpendicular. If two angles are complementary, then their measures add up to 90 degrees. If two angles' measures add up to 90 degrees, then they are complementary. If two angles are supplementary, then their measures add up to 180 degrees.
To get the answer to this problem, first we have to subtract the marked up cost to the cost of the product. So we first minus 25.3 and 22.25. When we do this, we will get a difference of 3.05. This is the profit that you will earn. So after that, we have to divide 3.05 and 25.30 to get the mark up percentage. When we do this, we will get an answer of 0.12. So in order to convert that into a percentage, we just have to multiply it by 100 and we will get 12%.

Spearman's correlation
Spearman's correlation measures the strength and direction of monotonic association between two variables.
Monotonicity is "less restrictive" than that of a linear relationship.
For example, the middle image above shows a relationship that is monotonic, but not linear.

ANSWER
C. x=7
EXPLANATION
The given exponential equation is
We rewrite the right hand side as 3 raised to exponent 2.
Observe that the base of both sides of the equation are equal.
We now equate the exponents.
Solve for x,
The correct choice is C.
