13r=3/7 what is r?

Mathematics

R = 3/91 since 3/7 is equal to .42857 and 13 divided by .42857 is 3/91.

The answer would be D) R = 3/91. Here are the steps.

1. divide both sides by 13

2. reduce 3/7 and 13 to 3/7*13

3. reduce 7 * 13 to 91.

* Reduce = Simplify.

Ulleksa [173]

Answer:

See explaination for the details of the answer

Step-by-step explanation:

Defect per opportunity DPO = defects/ no. of opportunities = 2/25 = 0.08

Defect per million opportunities

DPMO = DPO * 1 million

DPMO = 0.08 * 1 million = 80,000

six sigma = 2.9, take the dpmo at higher level if not exact 80800 for 2.9

P(a)=0.50 p(b)=0.30 and p(a and b)=0.15 what is p(a or b)
Softa [21]

Answer:

Option C is correct

P(A or B) = 0.65

Step-by-step explanation:

<u>Given: </u>

P(A) =0.5

P(B)=0.30

P(A and B) =0.15

( The probability of the happening of both independent events will be there product) P( A and B ) =P(A).P(B)

<u>Solution:</u>

To find the probability  of the Happening of event A either event B  we will use the following formula

P(A or B) = P(A) + P(B)-P(A and B)

                  = 0.5 + 0.3 - 0.15

                  =0.65

Determine
mihalych1998 [28]

Answer:

=4.+2.

Step-by-step explanation:

<u>Linear Combination Of Vectors </u>

One vector \vec b is a linear combination of \vec a_1 and \vec a_2 if there are two scalars x_1, x_2 such as

\vec b=x_1\vec a_1+x_2\vec a_2

In our case, all the vectors are given in R^3 but there are only two possible components for the linear combination. This indicates that only two conditions can be used to determine both scalars, and the other condition must be satisfied once the scalars are found.

We have

\vec a_1=,\ \vec a2=,\ \vec b=

We set the equation

=x_1.+x_2.

Multiplying both scalars by the vectors

=+

Equating each coordinate, we get

4x_1-4x_2=8

5x_1+3x_2=26

-4x_1+3x_2=-10

Adding the first and the third equations:

-x_2=-2

x_2=2

Replacing in the first equation

4x_1-4(2)=8

4x_1=8+8

x_1=4

We must test if those values make the second equation become an identity

5(4)+3(2)=20+6=26

The second equation complies with the values of x_1 and x_2, so the solution is

=4.+2.

What is JK? please explain/show your work on how you got your answer​
Travka [436]

Answer:

  • JK = 20 m

Step-by-step explanation:

  • <em>A line segment that connects two midpoints of the sides of a triangle is called a midsegment.</em>
  • <em>A triangle midsegment is parallel to the third side of the triangle and is half of the length of the third side.</em>

Point J is midpoint of side HI as HJ = JI

Point K is midpoint of side GI as GK = KI

JK is midsegment as connects the midpoints of the sides

JK = 1/2HG as per property of midsegment

  • 6x - 4 = 10x/2
  • 6x - 4 = 5x
  • 6x - 5x = 4
  • x = 4

JK = 6x - 4 = 6*4 - 4 = 24 - 4 = 20 m
