Explain how to do this problem in steps and include answers as well

vlabodo [156]

$8(4x - 5)-12=20x-10$

$32x - 40-12=20x-10$

$32x -52=20x-10$

$32x -52 -20x=-10$

$12x -52=-10$

$12x =-10 +52$

$12x =42$

$x= \frac{42}{12}$

$x = \frac{7}{2}$

$x=3 \frac{1}{2}$ ≈ 3.5

The mean of a set of data is -3.82 and its standard deviation is 2.31. Find the z score for a value of 3.99.

gtnhenbr [62]

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= $\frac{value-mean}{standarddeviation}$

= $\frac{3.99-(-3.82)}{2.31}$

= $\frac{3.99+3.82}{2.31}$

= $\frac{7.81}{2.31}$

= $3.38$

Thus, the z- score for a value of 3.99 will be 3.38.
