In a standard 52-card deck, half of the cards are red and half are black. The 52 cards are divided evenly into 4 suits: spades,

liubo4ka [24]

Answer:

It is more likely she draws 2 red cards

Step-by-step explanation:

Given that:

Number of red d cards in deck = 26

Number of face cards = 4 * 3 = 12 face cards

If two cards are drawn with replacement ;

Probability = (required outcome / Total possible outcomes)

P(1st card red) = 26 /52) = 1/2

P(2nd card red) = 26 /52 = 1/2

P(1st card red) * P(2nd card red)

1/2 * 1/2 = 1/4 = 0.25

P(1st card face card) = 12/52 = 3/13

P(2nd card, face card) = 12/52 = 3/13

P(1st card face card) * P(2nd card face card)

3/13 * 3 /13 = 9/169 = 0.053

0.25 > 0.053

It is more likely she draws 2 red cards

In 1990 four towns had the same population. Since then, the population of town 1 grew by a factor of 1.02, the population of tow

Alborosie

Answer: Town 1

Step-by-step explanation:

Town 1's population is growing at a factor of 1.02 which means that it is increasing by 2% a year.

Town 2 is growing at a factor of 0.999 which means that it is decreasing at a rate of:

= 1 - 0.999

= 0.1%

Town 3's population is increasing by 150 a year and town 4 is 200 people a year.

Town 1 will eclipse them all eventually because it is <u>growing proportionally at 2%</u>.

Towns 3 and 4 will eventually see 150 and 200 people fall below 2% of their town's population which means they will be growing at a slower rate than Town 1.

In a city, 35% of the bus riders with a monthly pass are students. in a random sample of 50 bus riders with monthly passes, 23 a

inessss [21]

Answer:

ρ = 35% or 0.35

ρ with ^ = $\frac{23}{50}=0.46$ or equivalently 46%

Step-by-step explanation:

ρ represents the population proportion of the bus riders, with a monthly pass, who are students.

The population proportion is simply the percentage of the entire population with a particular characteristic. We have been informed that in a city, 35% of the bus riders with a monthly pass are students. This means that 35% of the whole population of bus riders with a monthly pass are students. Therefore, our ρ is simply 35% or 0.35.

ρ with ^ represents the sample proportion of the bus riders, with a monthly pass, who are students. This is a statistic or an estimator as it is normally used to estimate the value of ρ, the population proportion. It is calculated using the formula;

ρ with ^ = $\frac{x}{n}$

where n represents the size of the sample and x the number of individuals in the sample with a certain desired characteristic. We have been informed that;

in a random sample of 50 bus riders with monthly passes, 23 are students.

Using the above formula and the values given we have;

ρ with ^ = $\frac{23}{50}=0.46$ or equivalently 46%
