Suppose that the sitting back-to-knee length for a group of adults has a normal distribution with a mean of mu equals 23.4 in. and a standard deviation of sigma equals 1.2 in. these data are often used in the design of different seats, including aircraft seats, train seats, theater seats, and classroom seats. instead of using 0.05 for identifying significant values, use the criteria that a value x is significantly high if p(x or greater)less than or equals0.01 and a value is significantly low if p(x or less)less than or equals0.01. find the back-to-knee lengths separating significant values from those that are not significant. using these criteria, is a back-to-knee length of 25.6 in. significantly high? find the back-to-knee lengths separating significant values from those that are not significant.

i do not know the answer i am sorry

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
