The population mean and standard deviation are given below. Find the required probability and determine whether the given sample

nataly862011 [7]

The probability of the sample is 0.5 or 50%

<u>Explanation:</u>

Given:

Mean, μ = 20

Standard deviation, δ = 1.3

Probability of sample being less than 20.1 = ?

P (x < 20.1) = 20.1 - μ / δ √n

P (x < 20.1) = $\frac{20.1 - 20}{1.3\sqrt{61} }$

= 0.0098

P( x < 20.1) = P(z < 0.0098)

P (z < 0.0098) = 0.5

The value of P is found out using a z score table.

Therefore, probability of the sample is 0.5 or 50%

your realized income is 3167.89/month, and your fixed expenses are 954.32/every 2 weeks. if you save 50% of your discretionary m

svetlana [45]

Answer:

<em>each month, you are saving 629.625</em>

<em />

Step-by-step explanation:

Your income is 3,167.89 each month.

Every 2 weeks, your fixed expenses are 954.32.

=> Average fixed expenses for 1 week is: 954.32 / 2= 477.16

As there are 4 weeks in each month, so that your fixed expenses each month are: 477.16 x 4 = 1,908.64

Your discretionary money for each month = Your monthly income - Your monthly fixed expenses = 3,167.89 - 1,908.64 = 1,259.25

=> Your discretionary money for each month is 1,259.25

As you save 50% of discretionary money each month, so that your monthly saving can be calculated as following:

<em>Monthly saving = Monthly discretionary money x 50% </em>

<em />

<em>So that each month, you are saving 629.625</em>

Answer:

divide

7 / 6 = 1 r 6

1 / 6 cannot be done so we multiply by 10

10 / 6 = 1 r 4

4 / 6 cannot be done so we multiply by 10

40 / 6 = 6 r 4 so it is repeating

the answer would be 1.466666666

There is a decimal point because we have to divide the by 10 to cancel it out

Fiber One Bran Cereal boasts that it contains 57% of the Daily value of fiber you need. If 1 serving contains 14 grams of fiber,

Makovka662 [10]

The amount of fiber needed in a day is 7.98 grams

<h3>Proportions</h3>

Proportions are parts, in comparative relation to a whole.

In other words, proportions are fractions of a larger dataset

The given parameters from the question are given as:

Proportion of the daily value of fiber needed = 57%
Daily serving = 14 grams.

<h3>Amount of fiber</h3>

The amount of fiber needed in a day is the product of the proportion and the size of the daily serving.

So, we have:

$Amount = 57\% \times 14g$

$Amount = 7.98g$

Hence, the amount of fiber needed in a day is 7.98 grams
