formula is
.5 * b * h *length
Answer: Option D
D. 0.92
Step-by-step explanation:
The correlation coefficient "r" is a number between -1 and 1 that indicates how related are two variables X and Y.
The stronger the nearest correlation is, the value of r a -1 or a 1.
A negative correlation indicates that when X increases Y decreases.
A positive correlation indicates that when X increases Y increases.
A correlation close to zero implies that there is very little correlation of the variables. When this happens, the points are scattered in the graph.
In this case you can see in the graph that the points are not scattered, but aligned. You can also observe that when X increases Y increases also.
This allows us to conclude that the correlation is strong and positive. Therefore the correct option is option D.
Given:
The equation is
To find:
The slope intercept form of the given equation.
Solution:
The slope intercept form of a linear equation is
Where, m is slope and b is the y-intercept.
We have,
We need to isolate y. Add 10x on both sides.
Divide both sides by 20.
Therefore, the slope intercept form of the given equation is .
Answer:
first count the number of decimal places in the base number, as when multiplying decimals (see Decimal Multiplication. Next, multiply that number by the exponent. This will be the total number of decimal places in the answer.
