A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 193.2-cm and a standard deviation of 2.4-cm. For shipment, 8 steel rods are bundled together. Round all answers to four decimal places if necessary. What is the distribution of X? X ~ N(,)

What is the distribution of ¯x? ¯x~ N(,)

For a single randomly selected steel rod, find the probability that the length is between 192.1-cm and 192.8-cm.

For a bundled of 8 rods, find the probability that the average length is between 192.1-cm and 192.8-cm.

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .

30 feet

step-by-step explanation:

that would be 2 1/2 * 12

= 24 + 6

= 30 feet   (answer)
