Step-by-step explanation:

Margin of error of a confidence interval:

The margin of error of a confidence interval has the following format:

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which z is related to the confidence level, [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

In this question:

z wont change, neither will [tex]\sigma[/tex]

We want to increase n as such the margin of error is reduced to one third.

We have that the margin of error is inversely proportional to the square root of the size of the sample, which means that for the margin of error to be reduced to one third, the sample size has to be multiplied by [tex]3^2 = 9[/tex]. So

180*9 = 1620

Answer:

The smaller shape has 84% of the larger shape's area.

Step-by-step explanation:

Larger shape: 15 × 12 = (12 × 3) + (12 × 12) = 36 + 144 = 150 + 30 = 180

Smaller shape: 6 × 4.8 = (6 × 4) + (6 × 0.8) = 24 + 4.8 = 28.8

The percent difference is the absolute value of the quotient of the difference between the new value and the original value divided by the original value and then all multiplied by 100. (percentages are really just a fraction of 100)

[tex]|\frac{28.8-180}{180}|*100=|\frac{-151.2}{180}|*100=|-0.84|*100=0.84*100=84[/tex]

% difference = 84%

Hope this helps! Have a great day!

Answer:

0.1150 = 11.50% probability that the sample does not contain any fibers of polymer B

Step-by-step explanation:

Hypergeometric distribution:

The probability of x sucesses is given by the following formula:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

In which:

x is the number of sucesses.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

In this question:

Fibers are chosen without replacement, which means that we use the hypergeometric distribution.

92 fibers means that [tex]N = 92[/tex]

Sample of 10 means that [tex]n = 10[/tex]

No polymeter B which means that [tex]x = 0[/tex]

17 fibers of polymeter B which means that [tex]k = 17[/tex]

a. What is the probability that the sample does not contain any fibers of polymer B

This is P(X = 0).

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]P(X = 0) = h(0,92,10,17) = \frac{C_{17,0}*C_{75,10}}{C_{92,10}} = 0.1150[/tex]

0.1150 = 11.50% probability that the sample does not contain any fibers of polymer B

The probability that the sample does not contain any fibers of polymer B is 0.123

The given parameters are:

n = 92

A = 43

B = 17

C = 32

The probability of selecting a sample that contains polymer B is:

[tex]p = \frac{17}{92}[/tex]

[tex]p = 0.185[/tex]

Using binomial probability, we have:

[tex]P(x) = ^nC_x * p^x *(1 - p)^{n -x}[/tex]

The probability that a selection of 10 fibers do not contain polymer B is then calculated as:

[tex]P(0) = ^{10}C_0 * 0.185^0 *(1 - 0.185)^{10 -0}[/tex]

This gives

[tex]P(0) = 1 * 1 *(0.815)^{10}[/tex]

Evaluate the product

[tex]P(0) = 0.123[/tex]

Hence, the probability that the sample does not contain any fibers of polymer B is 0.123

Answer:

Step-by-step explanation:

Here i will show you how to calculate the Percent Change from 12 to 36.

Basically, we are trying to find the change from 12 to 36 in terms of percent. We do this in three steps:

1) Find the difference between 12 and 36 as a number.

2) Divide the result from Step 1 by the starting number 12.

3) Multiply the result you got on step two by 100 to get it in terms of percent.

this can be shotenn sown with a simple formulatso, to find the percent change from 12 to 36, we use this formula:

((Y-X)/X)*100 = Percent Change

X is the starting number 12, and Y is the ending number 36 that it changed to. When we enter these numbers into the formula, we get:

((36-12)/12)*100 = 200.00%

2 servings of Gerber Mixed Cereal for Baby and 3 servings of Gerber Mango Tropical Fruit Dessert should be used.

Step-by-step explanation:

Given that Gerber Product's Gerber Mixed Cereal for Baby contains, in each serving, 60 calories and 11 grams of carbohydrates, while Gerber Mango Tropical Fruit Dessert contains, in each serving, 80 calories and 21 grams of carbohydrates, and you want to provide your child with 340 calories and 75 grams of carbohydrates, in order to how many servings of each you should use, the following calculation has to be made:

(80 x 5) + (60 x 0) --- (21 x 5) + (11 x 0) = 400 --- 105

(80 x 4) + (60 x 1) --- (21 x 4) + (11 x 1) = 380 --- 95

(80 x 3) + (60 x 2) --- (21 x 3) + (11 x 2) = 360 --- 85

(80 x 2) + (60 x 3) --- (21 x 2) + (11 x 3) = 340 --- 75

Therefore, 2 servings of Gerber Mixed Cereal for Baby and 3 servings of Gerber Mango Tropical Fruit Dessert should be used.
