A cities population rose 3% one year 0.08 the next year and buy 2/50 the next year or do these increases from least to greatest
Alinara [238K]

3% then 2/50 then 0.08 because 2/50 turns to 4% and 0.08 goes to 8%

A bag contains eleven equally sized marbles, which are numbered. Two marbles are chosen at random and replaced after each select
Digiron [165]

Answer:

B. \frac{24}{121}.

Step-by-step explanation:

Total number of marbles = 11.

Since, after choosing the first marble, we are putting it back and then the second marble is chosen.

As, there are 4 shaded marbles.

So, the probability of getting the first marble shaded = \frac{\binom{4}{1}}{\binom{11}{1}} = \frac{4}{11}

Also, there are 6 odd labeled marbles.

So, the probability of getting the second marble being odd labeled = \frac{\binom{6}{1}}{\binom{11}{1}} = \frac{6}{11}

So, the probability of getting the first marble shaded and second marble labeled odd = \frac{4}{11}\times \frac{6}{11} = \frac{24}{121}.

Hence, the required probability is \frac{24}{121}.

Suppose you have entered 79​-mile biathlon that consists of a run and a bicycle race. During your​ run, your average velocity is
kirza4 [7]

Answer:

The distance of the run is 10 miles

The distance of the bicycle race is 69 miles

Step-by-step explanation:

Let:

  • r = the distance for the run
  • 79 - r = the distance for the bicycle race
  • t = the time of the run
  • 5 - t = the time of the bicycle race

The run: r = 5t

The bicycle race: 79 - r = 23(5 - t)

Simplify the bicycle race:

  • 79 - r = 115 - 23t
  • -r = 36 - 23t
  • r = 23t - 36

Now we have two equations set up for r

  • r = 5t
  • r = 23t - 36

We know that r = r, so 5t must equal 23t - 36

  • 5t = 23t - 36
  • 5t + 36 = 23t
  • 36 = 18t
  • t = 2

Now we know that the run took 2 hours.

Plug it back into the equation for the run to find the distance for the run

  • r = 5t
  • r = 5(2)
  • r = 10

The run is 10 miles

To solve for the bicycle race, we simply subtract 10 from 79, because we know that the two distances combined are 79.

  • 79 - 10 = 69

The bicycle race is 69 miles.

An algorithm takes 5 seconds for input size 200. How long will it take for input size 1000 if the running time is linear (assume
tankabanditka [31]

The running time for an input size of 1000 will be 25 seconds.

To calculate the runtime of the Algorithm we need to know what an Algorithm is and how its runtime works.

<h3>What is the runtime of an Algorithm?</h3>

A finite sequence of rigorous instructions, used to solve a critical problem of a specific class or for computational purposes is called an Algorithm. The time taken to complete the said task is called the runtime of an Algorithm.

Let us now solve the question about linear running time of an algorithm.

Input size(N_{1})=200

Time taken(T_1)=5 seconds

Final input size(N_2)=1000

Let the final time taken be T.

Now we know that: \frac{N_1}{T_1}=\frac{N_2}{T_2}

Substituting the values we get T_2=25 seconds .

Therefore the linear running time for an input size of 1000 is 25 seconds.
