Answer:
r = A/(Pt) -1
Step-by-step explanation:
To solve for r, we undo the operations done to it. r is ...
- added to 1
- and the sum multiplied by Pt
We undo these operations in reverse order, so we first divide by Pt:
... A/(Pt) = 1 + r
Then, we subtract 1:
... A/(Pt) -1 = r
triangle:
a plane figure with three straight sides and three angles.
rectangle:
a plane figure with four straight sides and four right angles, especially one with unequal adjacent sides, in contrast to a square.
circle:
round plane figure whose boundary (the circumference) consists of points equidistant from a fixed point (the centre).
cylinder:
solid geometrical figure with straight parallel sides and a circular or oval cross section.
cone:
surface or solid figure generated by the straight lines which pass from a circle or other closed curve to a single point (the vertex) not in the same plane as the curve.
Answer: since his rock collection has 25 fewer rocks, and his contains 125,
Add that= 125+25=150
Step-by-step explanation: hope this helps
The correlation coefficient (r) is a number that describes how closely the numbers in the data set are related. The correlation coefficient will always be between −1.0 and +1.0. If the correlation is positive, there is a positive relationship. If it is negative, the relationship is negative. If the two are not correlated at all, the correlation coefficient will be 0. Strong and weak correlations are a little more subjective in that there is no exact cutoff between strong and weak, but generally, any r value that is close to either 1 or negative 1 is considered strong. Any value of r that is closer to 0 is considered weak.
