Answer:

Year 1

As per company book deprecation: (Equipment cost-Salvage value)/Life time = (50,000 - 5,000)/10 = 45,000/10 = $4,500

As per income tax depreciation = Cost * MACRS rate for year 1 = 50,000 * 20% = $10,000

Therefore, difference in year 1 will be: $10,000 - $4,500 = $5,500

Year 1

As per company book deprecation: (Equipment cost-Salvage value)/Life time = (50,000 - 5,000)/10 = 45,000/10 = $4,500

As per income tax depreciation = Cost * MACRS rate for year 2 = 50,000 * 32% = $16,000

Therefore, difference in year 1 will be: $16,000 - $4,500 = $11,500

Answer:

[tex]\mathbf{\int \dfrac{x^3}{\sqrt{9x^4+ 6x^2 -1}} dx \ \ is \ \ equivalent \ \ to \ \ \dfrac{1}{18} \int ( \sqrt{2}* sec^2 \theta - sec \theta) d\theta}[/tex]

Step-by-step explanation:

[tex]\int \dfrac{x^3}{\sqrt{9x^4+ 6x^2 -1}} dx = \int \dfrac{x^3 \ dx}{\sqrt{(3x^22)^2 + 2(3x^2) (1) + 1-2}}[/tex]

[tex]\implies \int\dfrac{x^3 \ dx}{\sqrt{(3x^2 +1)^2-2}}[/tex]

let;

[tex]3x^2 + 1 = \sqrt{2}\ sec \theta[/tex]

[tex]6xdx = \sqrt{2} sec \theta tan \theta \ d \theta[/tex]

[tex]xdx = \dfrac{\sqrt{2}}{6} sec \theta tan \theta \ d \theta[/tex]

[tex]\implies \int\dfrac{x^2*x \ dx}{\sqrt{2 \sec^2 \theta -2}}[/tex]

[tex]\implies \int\dfrac{\dfrac{1}{3}(\sqrt{2} \ sec \theta - 1)*\dfrac{\sqrt{2}}{6} sec \theta tan \theta \ d\theta }{\sqrt{2 } \ tan \theta }[/tex]

[tex]\implies \dfrac{1}{18} \int ( \sqrt{2}* sec \theta - 1) \ sec \theta d \theta[/tex]

[tex]\implies \dfrac{1}{18} \int ( \sqrt{2}* sec^2 \theta - sec \theta) d\theta[/tex]

∴

[tex]\mathbf{\int \dfrac{x^3}{\sqrt{9x^4+ 6x^2 -1}} dx \ \ is \ \ equivalent \ \ to \ \ \dfrac{1}{18} \int ( \sqrt{2}* sec^2 \theta - sec \theta) d\theta}[/tex]

The given expression as a decimal is 11.717

A decimal is a standardized system of writing numbers that include the expression of both integers and non-integers numbers.

In the given question, we are to write the expression:

In figures, we have:

The 717 thousandths can be expressed as 0.717 in decimal

Answer:

11.0707

Step-by-step explanation:

We use the word "and" to represent a decimal point. The words before "and" translate to 11 so we write 11 to the left of the decimal point.

11.

The place value indicated by the last word is the ten-thousandths place, so we should mark off four spaces to the right of the decimal point.

11.

The words to the right of "and" translate to 0707. Placing the digits of 0707 into the spaces, with the final digit in the last place, and filling in the empty spaces with zeros gives

11.0−−−7−−−0−−−7−−−,

so eleven and seven hundred seven ten-thousandths is written 11.0707.

Step-by-step explanation:

Answer:

0.2833 = 28.33% probability that a student in the class chosen at random is neither an Actuarial Statistics nor a Data Science major

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question, we have that:

There are 300 students.

80 + 5 = 85 are not Actuarial statistics or data science majors. So

[tex]\frac{85}{300} = 0.2833[/tex]

0.2833 = 28.33% probability that a student in the class chosen at random is neither an Actuarial Statistics nor a Data Science major

Answer:

I only know that Y equals 27

Step-by-step explanation:

because the side its Y

Answer:

y= 27 and x= 63

Step-by-step explanation:

for y its is 27 because the other one is 27 and they are the same angle and x=  

63 because a straight line=180 and then there are two 27 angles and you add 27+27=54 then  that by 180 180-54=126 the divide it by 2=63 because there are two of that same angle

Step-by-step explanation:

so what you're going to want to do is set this equal to 0. add the 6 over. add the 30 over. subtract 16x-14x they have the same degree of power so you can do that. divide the coefficient of x over and x=12 maybe who really knows anymore

Step-by-step explanation:

The smaller number is 14 and the bigger number is 49.

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

One number is 7 more than 3 times another number. Their sum is 63.

Let the one number be x and the other number be y. Then the equation will be

x = 3y + 7           ...1

x + y = 63           ...2

From equations 1 and 2, then the value of the variables x and y will be

3y + 7 + y = 63

4y = 63 - 7

4y = 56

y = 14

Then the value of the variable x will be

x = 3 × 14 + 7

x = 42 + 7

x = 49

The smaller number is 14 and the bigger number is 49.

Answer:

Brittany number is 144

Cydney number is 64

Step-by-step explanation:

let Brittany number be x

let Cydney number be y

y=4/9x

x - y = 80 because x is more than y

so y=x - 80

x - 80 = 4/9x

5/9x=80

a)

i.  x=- - - - - -

ii.  o=- - - - - -

iii.  Sx=- - - - -

b) The random variable X signifies the weights of the bags of candies which are selected at random.  

c) The statistics variable X  is a measure on a sample that is used as an estimate of the population mean.X  is the mean weight of the 16 bags of candies that were selected.

d) The distribution needed for this problem is normal distribution with parameters  because the population standard deviation is known.

N(X, o/[tex]\sqrt{n}[/tex])

So, the distribution is  

N(2, 0.12/[tex]\sqrt{16}[/tex])

e)

i. The 90% confidence interval for the population mean weight of the candies is  1.9589 , 2.0411

iii. The error bound is 0.0411

f)

i. The 98% confidence interval for the population mean weight of the candies is  1.9418 , 2.0582

iii. The error bound is 0.0582

g) The difference in the confidence intervals in part (f) and part (e) is of the level of confidence. The change is, the change in the area being calculated for the normal distribution. Therefore, the larger confidence level results in larger area and larger interval.

Hence the interval in part  is larger than the one in part (e).
