Answer:

112 cubic feet

Step-by-step explanation:

The answer is 112 cubic feet:

Why: Area of Rectangular Prism= L x W x H(LenghtxWidthxHeight)

                                                        4 x 2 x 14 = 112

Answer:

It's D on EDGE

Step-by-step explanation:

The compliment of the set S is {x|x is a rational non-integer}

The union of two sets A and B is the set of all those elements which are either in A or in B, i.e. A ∪ B, whereas the intersection of two sets A and B is the set of all elements which are common. The intersection of these two sets is denoted by A ∩ B

The union of two sets is a new set that contains all of the elements that are in at least one of the two sets

The intersection of two sets is a new set that contains all of the elements that are in both sets

Given data ,

Let the universal set be represented as U

where the value of U is

U = {x|x is a rational numbers}

And , let the second set be represented as S,

where S = {x|x is an integer}

Now , the compliment of set S is given by = S'

And , S' = 1 - S

On simplifying , we get

S' = 1 - {x|x is an integer} and it belongs to U

So , S' = {x|x is a rational non-integer}

Hence , the set is S' = {x|x is a rational non-integer}

Answer:

Step-by-step explanation:

Answer:

H0: Having health insurance is independent of the size of the company.

Ha: Having health insurance is not independent of the size of the company.

χ²= 9.284

The corresponding p-value for the test is  = 0.0096

Reject H0. We conclude health insurance coverage is not independent of the size of the company.

For small companies, 40% do not provide health insurance. For medium companies, 11.4% do not provide health insurance. For large companies,18 % do not provide health insurance.

These percentages support the conclusion that small companies are less more equally likely to provide health insurance coverage when compared to medium and large companies.

Step-by-step explanation:

       small medium large Total

yes      30         59         82              171

no       20            16        18             54

Total: 50             75       100        225

Expected Values      small         medium       large          Total

yes { 50* 171/225} = 38                   57                76         171

no                                 12               18                   24              54

Total                   50                      75            100                     225  

Squared Distances                small           medium            large

yes                     {(30 - 38)^2}/38

                                          = 1.684                 0.07              0.474

no                      {(20 - 12)^2} /12

                                      = 5.333                   0.22                 1.5

1) The  null and alternative hypotheses can be formulated as

H0: Having health insurance is independent of the size of the company.

Ha: Having health insurance is not independent of the size of the company.

(2) the significance level is alpha =0.05 ,

the number of degrees of freedom is df = (2 - 1) * (3 - 1) = 2df

so then the rejection region for this test is  χ 2 :χ 2 >5.991.

3) Test Statistics under H0 is

χ²= ∑ (O - E)²/ E where O is the observed and E is the expected frequency

4) χ²= 1.684+5.333+0.07+0.222+0.474+1.5

= 9.284

Since it is observed that χ²=9.284 >χ²= 5.991  it is concluded that the null hypothesis is rejected.

5) Conclusion

It is concluded that the null hypothesis H0 is rejected. Therefore, there is not enough evidence to claim that the two variables are dependent at 0.05 significance level.

The corresponding p-value for the test is  = 0.0096

b)  The percentages of

Small %= 20/50= 0.4= 40%

Medium %= 16/75 = 0.786= 11.4%

Large %= 18/100= 0.18= 18%

For small companies, 40% do not provide health insurance. For medium companies, 11.4% do not provide health insurance. For large companies,18 % do not provide health insurance.

These percentages support the conclusion that small companies are less more equally likely to provide health insurance coverage when compared to medium and large companies.

The weight (in grams) of a liquid is 456.63 grams.

Weight is a quantity representing the force exerted on a particle or object by an acceleration field, particularly the gravitational field of the Earth at the surface.

V = Volume of liquid = 182.8 milliliter

[tex]\rho[/tex] = Density of liquid = 0.135 grams over milliliter

Answer:

x= -22

Step-by-step explanation:

3x=5x+44

subtract 2x from both sides and leave only x on one side 3x(-2x)=5x(-2x)+44

then you get

x=3x+44

then you subtract the 3x to both sides

x(-3x)=3x(-3x)+44

then you get

-2x=44

and divide 2 on each side so-

x= -22

Answer:

It's C, 3

Step-by-step explanation:

Just did the problem and got it right :]

The limit of the given function when x approaches to 1 will be DNE.

What is limit?

An output value that a function approaches for the specified input values is referred to as a limit.

What will be the limit of the given function when x approaches to 1?

When we substitute 1 into the function then the denomiantor will be 1-1 and its value will be 0 .

As the denominator is 0 after plugging the limit this result that the limit will not exist.

Therefore, the correct answer is limit does not exist (DNE).

Answer: 224

Step-by-step explanation:

The total degrees of a 7-sided shape is 900. You can find that out using the equation (n-2) times 180. Where n is the number of sides. If you add up all the interior angles they equal 676. Then just subtract 676 from 900. 900-676= 224 degrees. That is the missing interior angle.
