Write the series using summation notation. Then find the sum of the series.
ivolga24 [154]

Hello, please consider the following.

\displaystyle 1+2+3+...+12=\sum_{k=1}^{k=12} {k}=\dfrac{12*13}{2}=6*13=78

For the second we will need to put on the same denominator.

\displaystyle \dfrac{1}{2}+\dfrac{1}{4}+...+\dfrac{1}{14}=\sum_{k=1}^{k=7} {\dfrac{1}{2k}}\\\\=\dfrac{1}{2}\dfrac{420+210+140+105+84+70+60}{5*7*3*2*2}\\\\=\dfrac{1}{2}\dfrac{1089}{420}\\\\=\dfrac{1089}{840}=1.296429...

Thank you.

Which of the following situations results in an answer of 23 ? Select three that apply.
Nata [24]

Answer:

The first, second, and fourth questions.

Step-by-step explanation:

None of these result in an answer of 23, so I'm assuming that you meant 2/3.

<em />

<em>"Two gallons of water are needed to fill 3 fish tanks of equal size. How many gallons of water are required for each tank?"</em>

2 gallons divided between 3 tanks is 2 divided by 3, so 2/3.

<em />

<em>"Three cats share 2 cans of tuna. How much of a can does each cat receive?"</em>

2 cans divided between 3 cats - it's the same as the above problem, just with cats and tuna cans instead of tanks and gallons of water. Each cat gets 2/3 of a can.

<em />

<em>"Two bags of bird seed are split among 5 parrots. What fraction of a bag does each parrot receive?"</em>

2 bags divided between 5 parrots would be 2/5 of a bag for each parrot.

<em />

<em>"Two apples are split among 3 people. How much of an apple does each person receive?"</em>

Two apples split among 3 people - like the first 2 questions, this also equals 2/3.

<em />

<em>"Three dogs each drink 2 cups of water. How many cups of water do the dogs drink in all?"</em>

Three dogs EACH drink 2 cups of water means that the answer is 2*3=6 cups.

<em>"Three cupcakes are divided among 2 children. How much of a cupcake does each child receive?"</em>

Three cupcakes are split between 2 children - they will each get 3/2 of a cupcake, or 1 1/2.
