Sampling 4 pieces of precision-cut wire (to be used in computer assembly) every hour for the past 24 hours has produced the following results: hour bold x overbar r hour bold x overbar r hour bold x overbar r hour bold x overbar r 1 3.35" 0.76" 7 3.15" 0.48" 13 3.01" 0.80" 19 3.31" 1.61" 2 3.10 1.18 8 2.65 1.18 14 2.83 1.36 20 2.99 1.09 3 3.32 1.48 9 2.92 0.71 15 3.02 1.01 21 2.65 1.13 4 3.39 1.31 10 2.95 1.33 16 2.84 0.45 22 3.28 0.51 5 2.97 1.22 11 2.93 1.12 17 2.86 1.48 23 2.84 1.63 6 2.86 0.37 12 3.07 0.45 18 2.74 1.24 24 2.54 0.97 based on the sampling done, the control limits for 3-sigma x overbar chart are (round all intermediate calculations to three decimal places before proceeding with further calculations): upper control limit (ucl subscript x overbar) = 72.400 inches (round your response to three decimal places).

step-by-step explanation:

what was your answer?

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

example answer: "to determine if a sum is reasonable you can round each number to the nearest whole and compare the estimated sum to the actual sum."

hope this you and anyone else who needs the answer : ^)

josh is incorrect

x= 7 and x= -1

step 2 is wrong and honestly first step is not needed, you just need to figure out the factors

i know its wrong because if you plug in the solutions josh found, they do not work (in the original equation)

x^2 -6x -7 = 0

(x-7) (x+1) = 0

x-7=0 x+1=0

x= 7 x= -1
