Manufacture of a certain component requires three different machining operations. Machining time for each operation has a normal

Sunny_sXe [5.5K]

Answer:

Z = (60 - x + y + z) / √a + b + c

Step-by-step explanation:

Since it is a normal distribution, we must calculate the mean and standard deviation, since we do not have data, what we will do is leave them based on these:

Thus Total Mean time = M1 + M2 + M3

given:

M1 = x

M2 = y

M3 = z

Total Mean Time M = x + y + z

Now to calculate the standard deviation we first calculate the variance.

The total Variance V = V1 + V2 + V3

Given:

V1 = a

V2 = b

V3 = c

V = a + b + c

Thus Standard deviation SD of the complete operation is

SD = √ V

SD = √a + b + c

we need to find the probability that the mean time is less than or equal to 60 minutes, the first thing is to find the value of Z.

Formula of Z is:

Z = (X - M) / SD

In this case X = 60.

On plugging the values we get

Z = (60 - x + y + z) / √a + b + c

refer to the Z table and find the Probability of Z ≤ (60 - x + y + z) / √a + b + c

Consider the universal set U and the sets X, Y, Z. U={1,2,3,4,5,6} X={1,4,5} Y={1,2} Z={2,3,5} What is (Z⋃X′)⋂Y?

beks73 [17]

X' = U - X

= {1,2,3,4,5,6} - {1,4,5}

= {2,3,6}

(ZUX') = {2,3,5} U {2,3,6}

= {2,3,5,6}

(Z⋃X′)⋂Y = {2,3,5,6} ⋂ {1,2}

= {2}

Can someone help me with this system of equations

Trava [24]

Y = $\frac{1}{2}$ x + 3
y = x - 4

Since both equations are equal to y, you can set the two values equal to each other and solve for x.

$\frac{1}{2}$ x + 3 = x - 4 Multiply both sides by 2
x + 6 = 2x - 8 Add x to both sides
6 = 3x - 8 Add 8 to both sides
14 = 3x DIvide both sides by 3
4 $\frac{2}{3}$ = x

Now, plug the x value into one of the original equations, I'll plug it into y = x - 4.

y = x - 4 Plug in the x value
y = 4 $\frac{2}{3}$ - 4 Subtract
y = $\frac{2}{3}$

x = 4 $\frac{2}{3}$ and y = $\frac{2}{3}$
