Solution:

Area of Parallelogram = Base × Height

Opposite Sides of Parallelogram are equal.

⇒  Area of Parallelogram 1 ,

Since it is a Rectangle , because Adjacent sides have angle between their legs has measure equal to 90°.

Product of slopes

    =\frac{6-2}{2-0} \times \frac{2-0}{0-4}\\\\=2 \times \frac{-1}{2}\\\\= -1

Area of Rectangle=Length × Breadth

        =\sqrt{(2-0)^2+(6-2)^2}\times \sqrt{(0-4)^2 \times (2-0)^2}}\\\\=\sqrt{20}\times \sqrt{20}\\\\=20 Square units

⇒Area of Parallelogram 2,

\text{Base}=\sqrt{(2-0)^2+(-8+2)^2}\\\\=\sqrt{40}\\\\=2\sqrt{5}\\\\Height=\sqrt{[2-(-0.4)]^2+[0-(-1)]^2}=\sqrt{5.76+1}\\\\=\sqrt{6.76}\\\\=2.6

Height =2.6 units

   =\sqrt{40} \times 2.6\\\\=6.23 \times 2.6\\\\=16 \text{Square units}Approx

⇒≡ Difference in Area

=Area of Parallelogram 1 - Area of Parallelogram 2

    =20 -16

  =4 Square units  

Option A:

  Area of Parallelogram 1 is 4 unit greater than area of Parallelogram 2.

Wahaj buys a pizza for rs 800.A week later,the same piza costs rs 900.When wahaj asks the manger for the reason ,he explain that
lions [1.4K]

Answer:

12.5%

Step-by-step explanation:

The price increased from 800 to 900. So what is the PERCENTAGE INCREASE??

The increase is 900 - 800 = 100

To find this in terms of original, we need to divide 100 by 800 and multiply by 100 to get the "percentage". Let's do it:

\frac{100}{800}*100=12.5

So the increase is 12.5% and thus the general sales tax is 12.5%

Find the variance of this probability distribution. Round to two decimal places.​
attashe74 [19]

Answer:

Variance = 4.68

Step-by-step explanation:

The formula for the variance is:

\sigma^{2} =\frac{\Sigma(X- \mu)^{2}}{N} \\or \\ \sigma^{2} =\frac{\Sigma(X)^{2}}{N} -\mu^{2} \\

Where:

X: Values \\\mu: Mean \\N: Number\ of\ values

The mean can be calculated as each value multiplied by its probability

\mu = 0*0.4 + 1*0.3 + 2*0.1+3*0.15+ 4*0.05=1.15

\frac{\Sigma (X)^{2}}{N} =\frac{(0^{2}+1^{2}+2^{2}+3^{2}+4^{2})}{5} =6

Replacing the mean and the summatory of X:

\sigma^{2} = \frac{\Sigma(X)^{2}}{N} -\mu^{2} \\= 6 - 1.15^{2}\\= 4.6775

From data gathered in the period 2008−2012, the yearly value of U.S. exports can be modeled by the function E(x) = −228x3 + 2,25
vredina [299]

Answer:

The total value the U.S. imported and exported is 19364 billion dollars

Step-by-step explanation:

* Lets explain how to solve the problem

- The yearly value of U.S. exports can be modeled by the function

 E(x) = −228 x³ + 2,252.8 x² − 6,098.5 x + 11,425.8

# x is the number of years after 2008

# E(x) is the value of exports in billions of dollars

- The yearly value of U.S. imports can be modeled by the function

 I(x) = −400.4 x³ + 3,954.4 x² − 11,128.8 x + 17,749.6

# x is the number of years after 2008

# I(x) is the value of imports in billions of dollars

* We need to calculate the total value the U.S. imported and

 exported in 2012

∵ x is the number of years after 2008

∴ At 2012 x = 4 years

- Lets calculate the value of the exports in 2012

∴ E(x) = -228(4)³ + 2,252.8(4)² - 6,098.5(4) + 11,425.8

∴ E(x) = 8484.6 billion dollars

- Lets calculate the value of the imports in 2012

∴ I(x) = -400.4(4)³ + 3,954.4(4)² - 11,128.8(4) + 17,749.6

∴ I(x) = 10879.2 billion dollar

∵ The total value the U.S. imported and exported = E(x) + (I(x)

∴ The total value = 8484.6 + 10879.2 = 19363.8

∴ The total value = 19364 billion dollars

* The total value the U.S. imported and exported is 19364 billion dollars
