The current population of Fun City is 21000 people. If the population of the city will double every 51 years then the population

Arisa [49]

Answer:

The population of Fun City after 171 years would be 214563.

Step-by-step explanation:

The statement depicts a case of exponential growth, whose model is described below:

$p(t) = p_{o}\cdot r^{\frac{t}{T} }$ (1)

Where:

$p_{o}$ - Initial population, no unit.

$p(t)$ - Current population, no unit.

$r$ - Growth rate, no unit.

$t$ - Time, in years.

$T$ - Growth period, in years.

If we know that $p_{o} = 21000$ , $r = 2$ , $t = 171\,yr$ and $T = 51\,yr$ , then the population of the city after 171 years is:

$p(t) = 21000\cdot 2^{\frac{171}{51} }$

$p(t) = 214563$

The population of Fun City after 171 years would be 214563.

You are dealt two cards successively without replacement from a standard deck of 52 playing cards. Find the probability that the

Snowcat [4.5K]

Answer:

(D) 0.006

Step-by-step explanation:

Total number of cards :52

Please note that, all cards have a the possibility of appearing 4 times.

Hence total possible number of a '2' is 4 cards and so it is also for a '10'

Having this Understanding, let's solve the question properly.

The probability that the FIRST CARD is 2 = 4/52

Probability that the second card without replacement is a 10 = 4 / 51

P( 1st two and 2nd four)

4/52 * 4/51 = 4/663

= 0.0060332

Rounding to 3 decimal places = 0.006

If a spinner for a game is spun once, there is a 25% chance it will land on

bonufazy [111]

Answer:

$Pr = 0.6$

Step-by-step explanation:

Given

Let

$O \to Orange$

So:

$P(O) = 25\%$ --- probability of O

$n=2$ --- Number of spin

Using the complement rule, the probability that a spin will not land on orange is:

$P(O') = 1 - P(O)$

$P(O') = 1 - 25\%$

Express as decimal

$P(O') = 1 - 0.25$

$P(O') = 0.75$

On two spins, the probability that it will not land on orange is:

$Pr = P(O') * P(O')$

So, we have:

$Pr = 0.75* 0.75$

$Pr = 0.5625$

<em></em> $Pr = 0.6$ <em> --- approximated</em>
