A quality control expert at a pretzel factory took a random sample of 10 bags from a batch of over 500 bags and measured the amount of pretzels in each bag in the sample. The target amount is 440 g, and they
want to test if the mean amount is on target or not.
Let ji be the mean amount in each bag in the entire batch and ĉ be the mean amount in each bag in the
sample.
Which of the following is an appropriate set of hypotheses for their significance test?

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

step-by-step explanation:

it will be a cylinder. with a diameter of 8 and 4 single pieces high

answer is  

c.

36

step-by-step explanation:

where does the z at is it on the x axes or on the y axes any way if it is on the y axes put it horizontally and if it is on the x axes put it vertically
