Hi! Does anyone know the answer to this question? I’m bad at geometry and I’m struggling to get the answer. Please help!

Answers

Answer 1

The diagram is shown below

Point A is located at (0,8). It's exactly 8 units away from the origin (0,0).

Let's say point C is at the origin. That would mean segment AC is 8 units long.

Divide segment AC into four equal parts. Each part is 8/4 = 2 units long.

Move to point A(0,8) and then drop down 2 units to arrive at (0,6). Use your straightedge to draw a horizontal line from (0,6) until you reach the diagonal line AB. Mark point P on the diagonal line. Refer to the diagram to see what I mean.

Now move back to (0,6) and drop down another 2 units to get to (0,4). Draw a horizontal line through this point until you reach the diagonal line. Mark point Q on the diagonal line.

Repeat this process until you get to the origin. You'll find that segment AB has been cut into four equal parts. This works because we've divided AC into four equal parts, which helps divide AB into four equal parts. The two concepts are directly connected. More specifically, we're using similar triangles to help do the subdivisions here.

So this trick is very handy if you have a diagonal road you're trying to divide into four (or any number) equal parts. It's also useful if you are dealing with fencing and you want to divide which if your friends will take care of which portions of the fence. Those are just two examples of real world applications.

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.

Answer:

55 + (4x + 25) = 180

-55 -55

4x + 25 = 125

-25 -25

4x = 100

Divide by 4 on both sides

X = 25

Now we just replace the x with 25

4 x 25 = 100, 100 + 25 = 125 degrees is the missing angle of y
