Z-scores are used to determine the probability of data. The z-score for the given parameters in normal distribution is -6.35

The formula given to calculate the z-score is expressed as:

[tex]z = \dfrac{x-\mu}{\frac{\sigma}{\sqrt{n}} }[/tex]

Given the following parameters:

Mu = 1.36

n = 28
[tex]\sigma = 5[/tex]

Mean = 130

Substitute into the formula

[tex]z = \dfrac{130-136}{\frac{5}{\sqrt{28}} }\\ x = \frac{-6}{0.9449} \\z = -6.35[/tex]

Hence the z-score for the given parameters in normal distribution is -6.35

Answer:

integers are closed under division

Step-by-step explanation:

Integers are not closed under division.Let us consider two integers i and j.

Then  need not necessarily be an integer. For example, 2 and 3 are integers but  is not an integer. So the first option , namely, integers are closed under division is not true.

On the other hand, the remaining three options given are correct.

The volume of the bag of nuts is the amount of nuts it can contain

The volume of the bag of nuts is 84.78 cubic inches

From the figure, we have the following parameters:

The volume of a cone is calculated using:

V = 1/3 πr^2h

Substitute the known values

V = 1/3  * 3.14 * 3^2 * 9

Evaluate the product

V = 84.78

Hence, the volume of the bag of nuts is 84.78 cubic inches

Answer: Choice B) [tex]\sqrt{63}[/tex]

========================================================

Explanation:

Let's rewrite the given expression like so

[tex]3\sqrt{y+3}=\sqrt{3^2}\sqrt{y+3}\\\\3\sqrt{y+3}=\sqrt{9}\sqrt{y+3}\\\\3\sqrt{y+3}=\sqrt{9(y+3)}\\\\[/tex]

We can see that the radicand is a multiple of 9 since 9 is a factor.

This immediately rules out choices C and D because 75 and 84 are not multiples of 9.

-------------

Plug in the smallest positive integer (1) for y to get

[tex]\sqrt{9(1+3)}=\sqrt{9(4)} = \sqrt{36}\\\\[/tex]

The radicand 36 is larger than the radicand for choice A (18), meaning we can rule out choice A. There's no way to get a radicand of 18 since y = 1 is the smallest we can go for.

We can however get to 63 by using y = 4

[tex]\sqrt{9(4+3)}=\sqrt{9(7)} = \sqrt{63}\\\\[/tex]

Showing that choice B is of the form [tex]3\sqrt{y+3}[/tex] where y is a positive integer, specifically when y = 4.

Answer:

1.25 feet to the nearest hundredth.

Step-by-step explanation:

Voilume = π r^2 h

Here V = 48π , and area of the base = π r^2 = 121.

So  48π = 121h

h =  48π / 121

= 1.25 feet to the nearest hundredth.

Answer:

u should've cropped out ur name

Step-by-step explanation:

The equation that defines 'x' as a function of 'y' will be x = 5 - 3y. Then the correct option is A.

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

Let's check all the options, then we have

A. x = 5 - 3y, the independent variable is 'y' and the dependent variable is 'x'.

B. y = 0x + 5, the independent variable is 'x' and the dependent variable is 'y'.

C. x² + y² = 2, it is not a function because the number of values of 'x' and 'y' will be two.

D. x² = y, it is not a function because the number of values of 'x' will be two.

The equation that defines 'x' as a function of 'y' will be x = 5 - 3y. Then the correct option is A.

Accumulated Depreciation and Fees Earned would be sorted into Balance Sheet and Statement of Owner's Equity-Debit; and Income Statement-Credit.

Accumulated depreciation is the accumulation of an asset's depreciation through a specific point in its lifetime. It is a contra asset account, which means that its proper balance is a credit that decreases the asset's overall value.

A corporation debits depreciation expenditures and credits accumulated depreciation when accounting for depreciation in the general ledger. 

On the balance sheet, accumulated depreciation is recorded and shown underneath the line for associated capitalized assets.

Therefore, we can conclude that Accumulated Depreciation and Fees Earned would be sorted into the Balance Sheet.
