The probability of the number of defective circuit boards in a shipment is given in the tables for two different companies. Company A A 5-column table has 2 labeled rows. The first row is labeled Number defective (x) with entries 0, 1, 2, 3. The second row is labeled P (x i) with entries 0.21, 0.30, 0.41, 0.08. Company B A 5-column table has 2 labeled rows. The first row is labeled Number defective (x) with entries 0, 1, 2, 3. The second row is labeled P (x i) with entries 0.18, 0.32, 0.28, 0.22. What is the expected number of defective circuit boards for company A? What is the expected number of defective circuit boards for company B? Which company should be chosen for purchasing circuit boards? Explain.

Answers

Answer: company A: 1.36

company B: 1.54 A; lowest expected number of defective boards

Step-by-step explanation:

i got it right on edge

The weighted average is a generalization of the expected value. The company that should be chosen for purchasing circuit boards is Company A.

What is the expected value?

The weighted average is a generalization of the expected value. The expected value is the arithmetic mean of a large number of independently chosen random variable outcomes.

A.) The expected number of defective circuit boards for company A is,

Expected number = (0.21×0) + (0.30×1) + (0.41×2) + (0.08×3) = 1.36

B.) The expected number of defective circuit boards for company B is,

Expected number = (0.18×0) + (0.32×1) + (0.28×2) + (0.22×3) = 1.54

C.) Since the expected number of defective circuit boards for Company A is less, therefore, the company that should be chosen for purchasing circuit boards is Company A.

To find:

The other solution of the given equation.

Solution:

We have,

[tex]x^2-64=0[/tex]

It can be written as:

[tex]x^2-8^2=0[/tex]

[tex](x-8)(x+8)=0[/tex]              [tex][\because a^2-b^2=(a-b)(a+b)][/tex]

A politician is about to give a campaign speech and is holding a stack of thirteen cue cards, of which the first 3 are the most important. Just before the speech, she drops all of the cards and picks them up in a random order. What is the probability that cards #1, #2, and #3 are still in order on the top of the stack?

Answers

Answer:

The probability that cards # 1, # 2, and # 3 are still in order on the top of the stack is 0.045%.

Step-by-step explanation:

Since a politician is about to give a campaign speech and is holding a stack of thirteen cue cards, of which the first 3 are the most important, and just before the speech, she drops all of the cards and picks them up in a random order, to determine what is the probability that cards # 1, # 2, and # 3 are still in order on the top of the stack, the following calculation must be performed:

1/13 x 1/13 x 1/13 = X

0.076 x 0.076 x 0.076 = X

0.00045 = X

0.00045 x 100 = 0.045

Therefore, the probability that cards # 1, # 2, and # 3 are still in order on the top of the stack is 0.045%.

Hi, so in order to graph you need to know what all those numbers mean.

The -1/2x is the slope or the rise/rub
The -3 is the y-intercept

So start by placing the y-intercept (0,-3), then from there place the slope (-1/2), since the slope is negative instead of going up one and two to the left you are going to go down one and two to the right, then place a point and repeat. After repeating 2-3 times you should be able to connect the points in order to make a line. If you have any questions let me know!

Martika surfs with her friends at Virginia Beach. Her friend, Mark caught 8 waves out of 20 possible waves to ride in the shore. They plan to stay out in the water for 50 more waves. How many of the 50 waves do you predict Mark will catch?

Answers

Answer:

40 waves

Step-by-step explanation:

Prob (Mark catches waves) = Times waves caught / Total waves =  8 / 20 =  4 / 5 = 20%

Predicted waves out of 50 , caught = 4 / 5 or 20% of 50  = (4 / 5) x 50 = 40

Alternatively, multiplying numerator & denominator of wave catch probability ie 4 / 5 with 10 each , we get (4 x 10) / (5 x 10) = 40 / 50 . This also signifies 40 out of 50 waves are predicted to be caught.

C

4x+2y=10

D
4x+2y=8

−4x−2y=−10

Answers

Answer: B.

[tex]4x - 2y = 8\\-4x + 2y = -8[/tex]

Step-by-step explanation:

Let's solve your system by elimination.

4x−2y=8;−2x+2y=6

Add these equations to eliminate y:

   4x-2y=8  

 -2x+2y=6    

  2x=14

Substitute 7 for x in 4x−2y=8:  

(4)(7)−2y=8

−2y+28=8  (Simplify both sides of the equation)  

−2y+28+−28=8+−28  (Add -28 to both sides)

−2y=−20  

−2y/−2=−20/−2  (Divide both sides by -2)  

y=10
