If the total of 3 pizzas and a salad is $38.95 and the salad costed $11.98 and we want to get to the cost of 1 pizza then we need to subtract $11.98 out of the total, so $38.95-$11.98 which is equal to $26.97. Natalia bought 3 pizzas in total, so if we divide it by 3 then we should get the cost of 1 pizza. So, $26.97/3 and the answer to that should be $8.99 and that means that each pizza should cost $8.99.

A bag contains red marbles, white marbles, and blue marbles. Randomly choose two marbles, one at a time, and without replacement
dsp73

Answer:

P(First\ White\ and\ Second\ Blue) = \frac{3}{28}

P(Same) = \frac{67}{210}

Step-by-step explanation:

Given (Omitted from the question)

Red = 7

White = 9

Blue = 5

Solving (a): P(First\ White\ and\ Second\ Blue)

This is calculated using:

P(First\ White\ and\ Second\ Blue) = P(White) * P(Blue)

P(First\ White\ and\ Second\ Blue) = \frac{n(White)}{Total} * \frac{n(Blue)}{Total - 1}

<em>We used Total - 1 because it is a probability without replacement</em>

So, we have:

P(First\ White\ and\ Second\ Blue) = \frac{9}{21} * \frac{5}{21 - 1}

P(First\ White\ and\ Second\ Blue) = \frac{9}{21} * \frac{5}{20}

P(First\ White\ and\ Second\ Blue) = \frac{9*5}{21*20}

P(First\ White\ and\ Second\ Blue) = \frac{45}{420}

P(First\ White\ and\ Second\ Blue) = \frac{3}{28}

Solving (b) P(Same)

This is calculated as:

P(Same) = P(First\ Blue\ and Second\ Blue)\or\ P(First\ Red\ and Second\ Red)\ or\ P(First\ White\ and Second\ White)

P(Same) = (\frac{n(Blue)}{Total} * \frac{n(Blue)-1}{Total-1})+(\frac{n(Red)}{Total} * \frac{n(Red)-1}{Total-1})+(\frac{n(White)}{Total} * \frac{n(White)-1}{Total-1})

P(Same) = (\frac{5}{21} * \frac{4}{20})+(\frac{7}{21} * \frac{6}{20})+(\frac{9}{21} * \frac{8}{20})

P(Same) = \frac{20}{420}+\frac{42}{420} +\frac{72}{420}

P(Same) = \frac{20+42+72}{420}

P(Same) = \frac{134}{420}

P(Same) = \frac{67}{210}

Find the limit of the following sequence or determine that the limit does not exist. {5n/Squareroot 81 n^2 + 5} Select the corre
elixir [45]

Answer:

C. The sequence is monotonic and bounded. The limit is 5/9

Step-by-step explanation:

For this case we have the following n term:

a_n = \frac{5n}{\sqrt{81n^2 +5}}

And we can find the limit when x tend to infinity:

\lim_{n\to\infty} \frac{5n}{\sqrt{81n^2 +5}}

And we got this:

5 \lim_{n\to\infty} \frac{n}{\sqrt{81n^2 +5}}

Now we can divide by n the numerator and denominator like this:

5 \lim_{n\to\infty} \frac{1}{\sqrt{81 +\frac{5}{n^2}}}

And now we can apply properties of limits and we got this:

5 \frac{\lim_{n\to\infty} 1}{\lim_{n\to\infty} \sqrt{81 +\frac{5}{n^2}}}

And we got:

5 \frac{1}{9}=\frac{5}{9}

So then our sequence is bounded by \frac{5}{9}

By definition a monotonic sequence is a "sequence that is always increasing or decreasing".

For this case if we find:

a_1 = \frac{5}{\sqrt{86}}

a_2 = \frac{10}{\sqrt{329}}

We see that a_2 >a_1 and in general we see that a_n >a_{n-1}. So then the ebst answer for this case is:

C. The sequence is monotonic and bounded. The limit is 5/9
