All items produced in a factory are checked for defects. Of the 300 items checked, 3% were found to be defective. How many of the items are defective?

Answer:

1. Unbiased sample.

2. Self-selected sample.

3. Stratified sample.

4. Systematic sample.

5. Convenience sample.

6. Biased sample.

Step-by-step explanation:

1. Unbiased sample: sample where every member of the population has an equal chance of being selected.

2. Self-selected sample: sample where members volunteer to take part.

3. Stratified sample: members are selected from the different subgroups within a population.

4. Systematic sample: sample members are selected through the use of a rule.

5. Convenience sample: sample where representatives are easily accessible.

6. Biased sample: sample not representative of the entire population.

Answer:

452.4

Step-by-step explanation:

area is given by πradius squared which gives answer as 452.389

Answer:

452.39 because you have to take the radius squared times pie or 3.14 to get the area so your answer would be 452.39

Step-by-step explanation:

Answer:

Part 1 and 2: P represents principle, or the original cost of the mortgage. i represents the annualinterest rate (r/n), and t represents time. When you change the time it affects monthlypayments because theres either more or less time to pay off the mortgage. Having a longertime to pay off means you'll have lower monthly payments. When the interest rateincreases, the monthly payment increases. This is because the higher the interest rate, themore interest you're paying. Changing the principle means you either have more or lessmoney to pay off.P2: Increasing i will increase the total cost since more interest will be charged. Increasingtime means there's more periods for interest to gather so the total cost will increase.Shortening the time will decrease the total cost because there will be less time for interestto accumulate.

Answer:

(1) -27

Step-by-step explanation:

Answer:

0.75

Step-by-step explanation:

Step-by-step explanation:

[tex] \sin^2 (\frac{\pi}{4} - \alpha) = \frac{1}{2}(1 - \sin 2\alpha) [/tex]

Use the identity

[tex] \sin^2 \theta = \dfrac{1 - \cos 2\theta}{2} [/tex]

on the left side.

[tex] \dfrac{1 - \cos [2(\frac{\pi}{4} - \alpha)]}{2} = \frac{1}{2}(1 - \sin 2\alpha) [/tex]

[tex] \dfrac{1 - \cos (\frac{\pi}{2} - 2\alpha)}{2} = \frac{1}{2}(1 - \sin 2\alpha) [/tex]

Now use the identity

[tex] \sin \theta = \cos(\frac{\pi}{2} - \theta) [/tex]

on the left side.

[tex] \dfrac{1 - \sin 2\alpha}{2} = \frac{1}{2}(1 - \sin 2\alpha) [/tex]

[tex] \frac{1}{2}(1 - \sin 2\alpha) = \frac{1}{2}(1 - \sin 2\alpha) [/tex]

Congruence is when there are 2 objects that have the same shape and size, or they "mirror" each other.

Question 6:

Congruence:

Yes, these two objects are congruent.

Reason:

They are congruent, because they have the same size and shape, or that they  "mirror" each other.

Question 7:

Congruence:

Yes there is congruence, here. These two objects are similar shapes, but not completely congruent.

Reason:

These two objects have the same size, but not the exact same shape. If you look at point B you can see that the two angles are different, which means that they are similar shapes, but not completely congruent.

Answer:

Honestly i dont even know

Step-by-step explanation:

Answer:

5

Step-by-step explanation:

From [tex]y=a(x-h)^2+k[/tex]

The vertex is at (h, k)

Therefore, from [tex]y=2(x-3)^2+4[/tex]

The vertex is at (3,4).

Thus, the answer is 4. (3,4)

Answer:

your answer would be (4, 7)

Answer:

Step-by-step explanation:

AD is 11 and BC is 12. We know this because AD and BC are parallel, as well as AB and DC. This means all the right triangles are congruent. I hope you understand. Let me know if you need more explanation! Please mark brainliest if correct, too.

Answer:

If the slope of a line is negative, the line WILL intersect quadrants II and IV. X and Y intersects of the line with negative slope have the same sign. Therefore if X and Y intersects are positive, the line intersects quadrant I; if negative, quadrant III.

Equality Properties

Step-by-step explanation:

Step 1: Define

-5x - 1 ≤ -9

Step 2: Solve for x

Here we see that any value x greater than or equal to 1.6 would work as a solution.

Therefore, our answer is A. 1, as it doesn't work as a solution.

Answer:

A. 1.5 cm by 2.5 cm

B. 27 cm by 45 cm

C. 9 cm by 15 cm

D. 30 cm by 50 cm

Step-by-step explanation:

The dimensions of the original painting = 12 cm by 20 cm painting

Hence, the proportion is:

12/20 = 0.6

Hence, we compare the options given in the question.

A. 1.5 cm by 2.5 cm

= 1.5/2.5 = 0.6 , option A is correct

B. 27 cm by 45 cm

27cm/45 cm = 0.6 Option B is correct

C. 9 cm by 15 cm

9cm/15cm = 0.6 , Option C is correct

D. 30 cm by 50 cm

30 cm /50 cm = 0.6 Option D is correct

E. 6 cm by 14 cm

6cm/14 cm = 0.4285714286

Option E is not correct

Therefore, Options A to D are the correct options

Answer: they are not similar

Isosceles Right

Isosceles, since the two side lengths are equal, and it is a right triangle since it has a 90 degree angle and two other 45 degree angles.

Answer:

A. 18÷2/9

Step-by-step explanation:

A. 18÷2/9

B. 18×2/9

C. 2/9÷18

D. 9/2÷18

Let

Total length of box = 18 inches

Thickness of each book = 2/9 inches

Number of books that will fit into the box = x

Number of books that will fit into the box = Total length of box ÷ Thickness of each book

x = 18 ÷ 2/9

= 18 × 9/2

= 162/2

= 81 books

The correct answer is A. 18÷2/9

Answer:

the slope is 2

Step-by-step explanation:

rise over run - 2/1

Answer: yes

Step-by-step explanation:

Lets look at side AC and BC.

BC = 10

AC = 15

10/15 = 2/3

Now side CE and CD.

CD = 8

CE = 12

8/12 = 2/3

SO YES!
