Six different machines are being considered for use in manufacturing rubber seals. The machines are being compared with respect to tensile strength of the product. A random sample of four seals from each machine is used to determine whether the mean tensile strength varies from machine to machine. The following are the tensile-strength measurements in kilograms per square centimeter ×10−1 : Machine Machine
1 2 3 4 5 6

17.5 16.4 20.3 14.6 17.5 18.3
16.9 19.2 15.7 16.7 19.2 16.2
15.8 17.7 17.8 20.8 16.5 17.5
18.6 15.4 18.9 18.9 20.5 20.1

Required:
Perform the analysis of variance at the 0.05 level of significance and indicate whether or not the mean tensile strengths differ significantly for the six machines.

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

i dont get the question

step-by-step explanation:

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
