Neporo4naja [7]3 years ago

Answer:

  • A: 24,500
  • B: 11,800
  • C: 12,700

Step-by-step explanation:

Since the number of A seats equals the total of the rest of the seats, it is half the seats in the stadium: 49000/2 = 24,500.

The revenue from those seats is, ...

  24,500×$30 = $735,000

so the revenue from B and C seats is ...

  $1,246,800 -735,000 = $511,800

__

We can let "b" represent the number of B seats. Then there are 24500-b seats in the C section and the revenue from those two sections is ...

  24b +18(24500-b) = 511800

  6b = 70,800 . . . . . . . . . . . . . . . subtract 441000, collect terms

  b = 70,800/6 = 11,800 . . . . . . . seats in B section

  24,500 -11,800 = 12,700 . . . . . seats in C section

There are 24500 seats in Section A, 11800 seats in Section B, and 12700 seats in Section C.

The explicit formula for a sequence is
Alexandra [31]

Answer:

28

Step-by-step explanation:

Let n = 21, and evaluate the expression.

a_n = -2 + \dfrac{3}{2}(n - 1)

a_{21} = -2 + \dfrac{3}{2}(21 - 1)

a_{21} = -2 + \dfrac{3}{2}(20)

a_{21} = -2 + \dfrac{3}{1}(10)

a_{21} = -2 + 30

a_{21} = 28

What is the product of using scientific notation to solve the problem of 20.5 * 10 to the 7th power and 0.000036
Zina [86]

Answer:

  7.38×10^3

Step-by-step explanation:

The usual rules of exponents apply.

  (20.5×10^7)(3.6×10^-5) = (2.05)(3.6)(10^(8-5)) = 7.38×10^3

_____

<em>Additional comment</em>

You can have your scientific or graphing calculator or your spreadsheet compute this product for you and display the result in scientific notation. You can enter the numbers in scientific notation or in standard form in any calculator or spreadsheet. (For a spreadsheet, the first number would be entered 20.5e7 or 2.05e8.)

The applicable rule of exponents is ...

  (10^a)(10^b) = 10^(a+b)

Just as the place values increase by factors of 10 going to the left of the decimal point, so they decrease by factors of 10 to the right. The number 3 in 0.000036 is in the 5th place to the right of the decimal point, so has a place value of 10^-5.

son4ous [18]

Answer:

<em>The calculated value t = 2.038< 2.145 at 0.05 level of significance</em>

<em>Null hypothesis is accepted </em>

<em>There is the average rate is less than  μ ≤ 4</em>

Step-by-step explanation:

<u><em>Step(i):-</em></u>

<em>The Population of the mean 'μ' =4</em>

<em>sample size   'n' = 16</em>

<em>sample mean 'x⁻' = 4.53</em>

<em>given sample standard deviation 's' = 1.04</em>

<em>level of significance  α = 0.05</em>

<u><em>Step(ii)</em></u><em>:-</em>

<u><em>Null hypothesis:H₀</em></u> : There is no significance difference between two means

<u>Alternative hypothesis : H₁</u><em>: There is significance difference between two means</em>

Test statistic

<em>                     </em>t = \frac{x^{-} - mean}{\frac{S}{\sqrt{n} } }<em />

<em>                    </em>t = \frac{4.53-4}{\frac{1.04}{\sqrt{16} } }

                t = 2.038

<em>Degrees of freedom ν = n-1 = 16-1 =15</em>

t₀.₀₂₅ = 2.145

<u><em>Conclusion</em></u>:-

<em>The calculated value t = 2.038< 2.145 at 0.05 level of significance</em>

<em>Null hypothesis is accepted </em>

<em>There is the average rate is less than  μ ≤ 4</em>
