Answer:
base = 15 units
Step-by-step explanation:
We are given area of a triangle = 52.5 sq. units
Height is given as 7 and we have to find the base.
Using formula for area of triangle:
Area of triangle = 


52.5 * 2 = base × 7
105 = base × 7
base = 15
Answer <u>(assuming it can be in slope-intercept form)</u>:
Step-by-step explanation:
1) First, use the slope formula
to find the slope of the line. Substitute the x and y values of the given points into the formula and solve:

So, the slope is
.
2) Now, use the slope-intercept formula
to write the equation of the line in slope-intercept form. All you need to do is substitute real values for the
and
in the formula.
Since
represents the slope, substitute
for it. Since
represents the y-intercept, substitute 3 for it. (Remember, the y-intercept is the point at which the line hits the y-axis. All points on the y-axis have an x-value of 0. Notice how the given point (0,3) has an x-value, too, so it must be the line's y-intercept.) This gives the following equation and answer:

Answer: C) There is no positive or negative correlation
A positive correlation is one where the values are increasing, and the line of dots are clearly going down to up.
A negative correlation is the opposite. The values are decreasing, and the line goes from up to down.
This correlation is one that is neither positive or negative. It is a straight line where the values neither increase nor decrease.
