Answer:
The z- score for a value of 3.99 will be 3.38.
Step-by-step explanation:
It is given that the mean of a set of data is -3.82 and its standard deviation is 2.31.
Thus, the value of the z-score=
=
=
=
=
Thus, the z- score for a value of 3.99 will be 3.38.
Point form: (2,3) and x=2 and y=3
7 and 8 because the square root is 7.874
Answer:
y - 3 = - 4 ( x + 4)
Step-by-step explanation:
(-4,-3) and (4,1)
Slope = (1 + 3)/(4 + 4) = 2/8 = 1/4
Perpendicular lines, slope is opposite and reciprocal so slope of the line that is perpendicular to the given line is -4
Equation in point slope form, passing thru (-4 , 3)
y - 3 = - 4 ( x + 4)
