Answer:
5%
Step-by-step explanation:
1 person will be selected out of a total of 20 (you + 19)
The probability is 1/20 = 0.05 = 5%
Andrew= 4 yr.old
Sara=12 yr. old
Tom= 12 yr. old
Basically, what I did was guess and check, but there are other ways also. When I came with Andrew's age of 5 and it was pretty close, I went down to 4 years old and that worked perfect because that way both Tom and Sara are 12 years old.
Answer:
The equation of line in the form of Ax + By = C is:
Step-by-step explanation:
We need to find the equation of line, with the given slope passes through the given point.
Slope m = -4
Point: (-2,-9)
We need to find slope and y-intercept of the line.
The slope of line is given m = -4
Now, we need to find the y-intercept
Using the point (-2,-9) and slope m = -4, we can find y-intercept
The formula used will be:
Putting values of: y= -9, x =-2 and m = -4
So, y-intercept b = -17
Now, the equation of required line having slope m = -4 and y-intercept b = -17 is:
Writing equation in required form i.e. of Ax + By = C
So, the equation of line in the form of Ax + By = C is:
