A quality-conscious disk manufacturer wishes to know the fraction of disks his company makes which are defective. Step 1 of 2: Suppose a sample of 542 floppy disks is drawn. Of these disks, 37 were defective. Using the data, estimate the proportion of disks which are defective. Enter your answer as a fraction or a decimal number rounded to three decimal places.

Answers

Answer 1

Answer:

0.068 or 6.826%

Step-by-step explanation:

In order to calculate the proportion of disks that are defective, we need to divide the number of defective disks by the total amount of disks that were chosen in the given sample. Using the data provided this would be the following calculation...

37 / 542 = 0.068

We can multiply this by 100 to get the percentage value

0.068 * 100 = 6.826%

Therefore, roughly 6.826% of the entire disk population would be defective.

Kelli Rae invested $220,000 in a savings account with simple interest. After 10 years, Kelli Rae had $250,000. What is the interest rate on this account?

Answers

Answer:

Interest rate = 1.363% (Approx.)

Step-by-step explanation:

Given:

Amount invested P = $220,000

Amount after 10 year = $250,000

Number of year = 10 year

Find:

Interest rate

Computation:

A = P + I

Amount of interest = $250,000 - $220,000

⇒ Amount of interest = $30,000

Amount of interest = PRT

⇒ 30,000 = (220,000)(R)(10)

⇒ 30,000 = (2,200,000)(R)

⇒ R = 0.013636

Interest rate = 1.363% (Approx.)

Answer:

Step-by-step explanation:

Let us first resolve the given numbers into prime factors.

By prime factorization,

[tex] \longmapsto [/tex] √8 = √( 2 × 2 × 2)

[tex] \longmapsto [/tex] √8 = 2√2

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

[tex] \longmapsto [/tex] √98 = √( 2 × 7 × 7)

[tex] \longmapsto [/tex] √98 = 7√2

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

[tex] \longmapsto [/tex] √32 = √( 2 × 2 × 2 × 2 × 2)

[tex] \longmapsto [/tex] √32 = 2 × 2√2

[tex] \longmapsto [/tex] √32 = 4√2

According to the question,

[tex] \longmapsto [/tex] √8+√98+√32

[tex] \longmapsto [/tex] 2√2 + 7√2 + 4√2

Taking √2 as common.

[tex] \longmapsto [/tex] √2(2 + 7 + 4)

[tex] \longmapsto [/tex] √2(13)

[tex] \longmapsto [/tex] 13√2

So, we get that :

√8+√98+√32 → 13√2

What is the equation of the line that is parallel to the line 6x+3y=4 and has a y-intercept of −6?

Answers

Answer:

y=-2x-6

Step-by-step explanation:

Slope intercept form of a line: y=mx+b (m is the slope and b is the y-intercept)

Convert our given line 6x+3y=4 into slope-intercept form to find the slope

Subtract 6x on both sides

3y=-6x+4

Divide 3 on both sides

y=-2x+4/3

The slope of the given line is the coefficient of x, -2

Parallel lines have the same slope, so the equation we're solving for also has a slope of -2

We also know that the y-intercept is -6, so we now have all the info we need to make the equation:

y=-2x-6

Ann has $ 1, $10, and $20 bills. She has 4 times as many $20 bills as $10 bills. She has 3 times as many $1 bills as $20 bills. She has a total of $204 . Drag and drop the number of $1, $10, and $ 20 bills she has.

Answers

Answer:

Ann has 24 $1 bills, 2 $10 bills, and 8 $20 bills.

Step-by-step explanation:

Given that Ann has $1, $10, and $20 bills, and she has 4 times as many $20 bills as $10 bills and 3 times as many $1 bills as $20 bills, taking a total of $204, to determine the number of $1, $10, and $20 bills she has, she needs to perform the following calculation:

1 = 3x20 = 3x4x10 = 12x10

20 = 4x10

10 = 10

(12 x 1) + (4 x 20) + 10 = 12 + 80 + 10 = 102

(24 x 1) + (8 x 20) + (2 x 10) = 24 + 160 + 20 = 204

So Ann has 24 $1 bills, 2 $10 bills, and 8 $20 bills.

The perimeter of a rectangular chicken coop is 30 feet. the width is w feets and the length is w + 4 feet. what is the length and width of the coop

Answers

Answer: W=9ft. L=13ft

The width and length of the chicken coop are 5.5 feet and 9.5 feet respectively.

What is the perimeter of the rectangle?

The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.

The perimeter of a rectangle is given by P = 2L + 2W, where L is the length, W is the width and P is the perimeter.

We know that the width is w feet and the length is w+4 feet.

Given that the perimeter of the chicken coop is 30 feet, we can set up the following equation:

30 = 2(w + 4) + 2w

We can simplify this equation by combining like terms:

30 = 2w + 8 + 2w

30 = 4w + 8

22 = 4w

w = 5.5

So the width of the coop is 5.5 feet.

To find the length of the coop, we can use the information that the width is 5.5 feet and the length is w+4 feet.

The length of the coop is 5.5 + 4 = 9.5 feet

Write 174% as a fraction in simplest form.

Answers

Answer:

The answer should be [tex]\frac{87}{50}[/tex]

Step-by-step explanation:

1.74 = [tex]\frac{174}{100}[/tex] = [tex]\frac{87}{50}[/tex]

Answer:

174% = 87/50 = 1 37/50 as a fraction

Step-by-step explanation:

174% = 174/100

Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(174,100) = 2. So,

(174÷2)/(100÷2) = 87/50 when reduced to the simplest form.

As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 174/100 is also equal to 1 37/50 when expressed as a mixed number.

In reality, good nutrition is not always a one-size-fits-all deal. In fact, some people who read food labels might actually be putting harmful things into their bodies. For example, certain foods that are low in calories can be high in other things, such as sodium. Frozen dinners can be quite high in sodium, although some of those dinners are low fat. Someone looking for a low-calorie meal might do well to eat a frozen meal every now and then; many are portion-controlled and loaded with vegetables. However, someone who is under doctor's orders to control their sodium intake might want to make another choice. Just because a meal contains a lot of vegetables does not mean it is an equally good choice for everyone. In addition, some foods that are low in carbohydrates can be high in sugar. People often look at the number of carbs on a food's label because they know carbs contribute to fat. However, a product low in carbs but high in sugar can be equally damaging. Sugar does not break down quickly in the body. Products high in sugar can keep you coming back for more while simultaneously building fat. Therefore, someone looking to maintain a healthy weight must look at a product's carb and sugar content. Also, too much sugar contributes to diabetes, so people in danger of developing diabetes need to keep an eye on more than a label's carb count. In general, it is a good idea to try to weigh all items that are listed on a product's label. Trying to take into account all aspects of the food you eat is critical to your overall health and well-being. Being alert to a food's total nutritional value can help maintain good health for years to come.8Which sentence from the passage shows that people need to be more observant when it comes to reading food labels?
