Answer:

I believe the answer is commutative property of addition.

Step-by-step explanation:

It is commutative property of addition because you are just switching the numbers around but it has the same answer.

3+4=7 just like 4+3=7 also, so as you can see you can just switch th numbers around but the sum doesnt change, its still 7.

I’m pretty sure that’s commutative property

Motorola used the normal distribution to determine the probability of defects and the number

vovangra [49]

Answer:

a.P<x<9.85 orx>10.15)=0.3174, Total defects=317.4

b.p=0.0026,total defects=2.6

c.Less of the items produced will be classified as defects.

Step-by-step explanation:

a.The standard score,z, is esentially x reduced by process mean then divided my process standard deviation.

$\mu=10,\sigma=0.15\\Therefore:-\\z=\frac{x-\mu}{\sigma}=\frac{9.85-10}{0.15}\approx-1.0\\z=\frac{x-\mu}{\sigma}=\frac{10.15-10}{0.15}\approx+1.0\\P(x10.15)=P(Z+1.0)\\=2P(Z$

Total defects=Production*Probability

=0.3174*1000

$=317.4$

b. $\mu=10,\sigma=0.05$

therefore:-

$z=\frac{x-\mu}{\sigma}=\frac{9.85-10}{0.05}\approx-3.0\\z=\frac{x-\mu}{\sigma}=\frac{10.15-10}{0.05}\approx+3.0\\\\=P(x10.15)=P(Z+3.0)\\=2P(Z$

Defects=Probability*Production

=0.0026*1000

=2.6

c.Reducing process variation results in a significant reduction in the number of unit defects.

3x + 2 =11 (solve for x)

torisob [31]

Answer:

x=3

Step-by-step explanation:

first let's try to get just 3x on one side. to do this we can subtract 2 from both side of the equation.

3x+(2-2)=11-2

3x=9

now we have to isolate the variable we can divide both sides by 3:

3x/3=9/3

x=3

and you get the answer that x is 3

What are the coordinates of a point that is 7 strides west of (2,-1)

Marat540 [252]

(-5,-1) would be the coordinates since the only thing we’re changing by moving west is that we’re subtracting from the x value. Therefore, 2-7 is -5 so we get -5,-1
