Not sure how to solve

LekaFEV [45]

Answer:

The Y intercept doesn't exist, and the slope is undefined

Step-by-step explanation:

The graph provided for us is a vertical line. x= 7

this means the line will go up and down forever without a slant because x will always equal 7.

Ex:

X | Y

7 | -3

7 | -2

7 | -1

7 | 0

7 | 1

7 | 2

7 | 3

The average thickness of books on a library shelf is 8.3 centimeters. The standard deviation is 0.6 centimeter. If 20% of the bo

jeka57 [31]

Answer:

8.8 cm

Step-by-step explanation:

-We know that the top 20% of the books are oversized.

-We therefore find the z-value of the top 20%:

$z_{0.1}=8.4$

#We substitute the z value in formula to solve X.

$z=\frac{\bar X-\mu}{\sigma}$

Where

X is the minimum thickness of the book.

-Given $\sigma=0.6 \ , \mu=8.3$ , the minimum thickness,X can be calculated as follows:

$z=\frac{\bar X-\mu}{\sigma}\\\\0.84=\frac{\bar X-8.3}{0.6}\\\\\bar X=0.84\times 0.6+8.3\\\\=8.804\approx 8.8\ cm$

Hence, the minimum thickness of the oversized books is 8.8 cm
