elixir [45]

Answer:

  • See below

Step-by-step explanation:

<u>Surface area:</u>

  • S = 2(lw + lh + wh) + 2πrh
  • S = 2(9*4 + 9*5 + 4*5) + 2*3.14*2*3 = 239.7 cm² (rounded)

<u>Volume:</u>

  • V = lwh + πr²h
  • V = 9*4*5 + 3.14*2²*3 = 217.7 cm³ (rounded)

Scott bought a 5lb bag of cookies at the bakery. He ate 2/5 of the bag and his sister ate 2/9 of the bag. What fraction of the b
satela [25.4K]

Answer:  Fraction they both eat = \dfrac{28}{45}.

Fraction of bag remains =  \dfrac{17}{45}

Step-by-step explanation:

Given: Part of cookies eaten by  Scott = \dfrac25

Part of cookies eaten by sister = \dfrac{2}{9}

Fraction they both eat = \dfrac25+\dfrac29=\dfrac{9\times2+5\times2}{5\times9}

=\dfrac{18+10}{45}\\\\=\dfrac{28}{45}

Fraction of the bag remain = 1-\dfrac{28}{45}=\dfrac{45-28}{45}=\dfrac{17}{45}

[Taking fraction of whole bag =1]

Hence, Fraction they both eat = \dfrac{28}{45}.

Fraction of bag remains =  \dfrac{17}{45}

What is the difference between the mean and the median of the data set?
Pepsi [2]
As you probably know there is a difference between mean and median -- the mean acts as a measure of the average, and on the other hand median measures the middle number. The median in this is 15 and the mean is also 15.
