Answer:
Step-by-step explanation:
The inverse operation for an exponential () is the logarithm: .
Coefficient of variation is the ratio of the standard deviation to the mean (average)
Coefficient of variation = (standard deviation/mean) × 100

Answer:
y - 4 = 3(x - 1)
Step-by-step explanation:
It looks like you have slope 3 and a point (1, 4)
so it should be y - 4 = 3(x - 1)
which is your first choice: y minus 4 = 3 (x minus 1)
Answer:
Object point Q (x,y) ------------- image point Q'( -y,x)
Step-by-step explanation:
When a point A (x,y) is rotated 90 degrees counterclockwise about the origin the resulting image of the point is A'(-y,x)
This means first you alternate the positions of x and y coordinates then add a negative sign on the now new y coordinate.
Example a point B(2,3) rotated 90° counterclockwise about the origin will form an image B'(-3,2)
So if point Q (x,y) ------------- image Q'( -y,x)
Substitute real values for (x,y) coordinates to get correct answer.
Answer:
75 degrees
Step-by-step explanation:
let x unknown number
5x+10x+9x=180
24x=180
x=7.5
largest angle
10x
10×7.5=75
