(c) Calculate the probability that the first three appears before the twentieth roll but not before the fifth roll.

Answer:

the correct answer is c. 415in

Step-by-step explanation:

You have to multiply the base radius by the height.

Answer:

area of cross section of cylinder is  inch²

Step-by-step explanation:

Given : Cylinder is 7 inch tall and has a volume of inches³.

We have to find the area of cross section of cylinder.

Area of cross section of cylinder =

To find the cross section first find radius.

Given Volume of cylinder = inches³

Also , Volume of cylinder =

Thus,

Divide both side by 7, we get,

On simplifying , we get,

Since, radius has to be positive, thus neglecting negative term.

Thus, radius of cylinder = 3 inch

Thus, area of cross section of cylinder =

area of cross section of cylinder =

Thus, area of cross section of cylinder is  inch²

Low interest rates are better than high interest rates when borrowing money, whether with a credit card or a loan. A low interest rate or APR (annual percentage rate) means you're paying less for the privilege of borrowing over time. High interest rates are only good when you're the lende

Answer:

The right answer is B.

Step-by-step explanation:

To be sure if three sides could be used to form a triangle, you need to remember that two sides of a triangle added together is always greater than the final side. B is the only selection that does not work for the law, 3 + 5 = 8 which is smaller than 10, so the corrct answer is B.

Answer:

  (x, y) = (5, 4)

Step-by-step explanation:

Subtracting the second equation from the first eliminates the x term.

  (4x +6y) -(4x +2y) = (44) -(28)

  4y = 16 . . . . simplify

  y = 4

Using the second equation to find x, we have ...

  4x +2(4) = 28

  x + 2 = 7 . . . . . . divide by 4

  x = 5 . . . . . . . . . subtract 2

The solution is (x, y) = (5, 4).

Answer:

y = 3/2x - 18

Step-by-step explanation:

y = mx + b

-6 = 3/2(8) + b

-6 = 12 + b

b = -18

Answer:

4.75

Step-by-step explanation:

19/4 = 4.75

Answer:

1.36+3+(32)(2)

=57

error is that 6 is the wrong answer

The solution for b could really be any answers as long as when that number is  divided by 4.3 it is less than 11.3

1 possible answer though could be 11.3

Because when 11.3 is divided by 4.3 it is less then 11.3

Sorry if I'm missing something and the answer is wrong!

i just did 4 times 4 and add it  to 8 times 2

Answer:

The area of the figure is 28.

Step-by-step explanation:

First, split it into a square and a trapezoid.

Then calculate the area of each of them.

Square = 4 times 4 = 16

Trapezoid = ((4 + 2)/ 2)*4 = 12

12 + 16 = 28

I hope this helps :)

Answer:

For smaller numbers you can simply look at the factors or multiples for each number and find the greatest common multiple of them.

For 18 and 45 those factors look like this:

. Factors for 18: 1,2,3,6,9 and 18

. Factors for 45: 1,3,5,9,15 and 45

As you can see when you list out the factors of each number, 9 is the greatest number that 18 and 45 divides into.

Answer:

y=-2+4

Step-by-step explanation:

we know the y intercept is four, so we can plug that into y=mx+b

so far we know y=mx+4

and the equation for finding slope is [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

so let's find two points on the graph

let's make it easy on ourselves and use the points laid out for us

(0,4) and (2,0)

[tex]\frac{0-4}{2-0}[/tex]

solving that would come out to be [tex]\frac{-4}{2}[/tex]

simplified, that would be -2

now that we know the slope, we can put them into slope-intercept form

y=-2+4

Answer:

Behavioral Research in Accounting (January 2008) study of Machiavellian traits in accountants

a) Population of interest to the researcher: accountants

b) Sample = 700 accounting alumni

c) The inference made by the researcher = Machiavellian behavior is not required to achieve success in the accounting profession.

d) The non-responses reduce the sample size and this might introduce bias to the inference made to the population.

Step-by-step explanation:

a) Data and Calculations:

Research Question = Is Machiavellian behavior is required to achieve success in the accounting profession?

Population of interest = all accountants

Sample size = 700 accounting alumni of a university

No. of analyzed questionnaires = 198

No. of questionnaires not analyzed due to nonresponse and incomplete answers = 502 (700 - 198)

Percentage of analyzed questionnaires to sample size = 28.3% (198/700 *100)

Percentage of questionnaires not analyzed = 71.7% (100% - 28.3%)

Conclusion reached by the researchers = Machiavellian behavior is not required to achieve success in the accounting profession.

Step-by-step explanation:

The inverse functions “undo” each other, You can use composition of functions to verify that 2 functions are inverses. When you compose two inverses… the result is the input value of x. 3 3 g x x = Because f(g(x)) = g(f(x)) = x, they are inverses.
