Answer:
D.
Step-by-step explanation:
If she connects it to any other point the angle would be more then 30 degrees.
Just go through it phrase by phrase by phrase - one step at a time.
2*( )
2*(x - 7)
Move all terms not containing x to the right side of the equation
x=9
Graph the line using the slope and y-intercept, or two points.
Slope= -5
y- intercept= (0,2)
The answer has two points (0,2) and (1,-3) place them and then make a line going left through them.
Answer:
lower than Amanda: 816 students
Step-by-step explanation:
An equivalent way in which to state this problem is: Find the area under the standard normal curve to the left (below) 940.
Most modern calculators have built in distribution functions.
In this case I entered the single command normalcdf(-1000,940, 850, 100)
and obtained 0.816.
In this particular situation, this means that 0.816(1000 students) scored lower than Amanda: 816 students.
