The equation of the line thru <span> (14,5) and (19,15) is found as follows:
15-5 5
slope = m = ----------- = ------ = -1
19-14 5
Thus, the slope of any line perpendicular to this first line has the slope
m = -1/1 = -1.
Then, using the point-slope form, y-15 = -1(x-19), or y -15 = -x + 19, or
y= -x + 34 (answer)</span>
Answer:
Step-by-step explanation:
The total number of triangles is 5
The total number of all shapes is 13
The ratio is triangles to total
The ratio is 5 to 13
Note
This problem is not very well defined. Notice the circle at the bottom left. It's less than 1/2 a circle. Question: do you count it or don't you. The answer to that question will influence other partial figures.
All you do is count the total number of figures and the number of triangles. I did count the part circle on the lower left as with the triangles that are missing their tops.
Answer:
A
Step-by-step explanation:
The reason it has to be A is because you don't have to even thing about the standard deviation right here because the only answer that has a mean of 131 is answer A.
Hope it helps have a great afternoon:)
